1.Kuyini ukusebenza kwe-downhole?
Ukusebenza kwe-Downhole kuyindlela yobuchwepheshe yokuqinisekisa ukukhiqizwa okuvamile kwemithombo kawoyela namanzi ohlelweni lokuhlola nokuthuthukiswa kwendawo kawoyela. Uwoyela negesi yemvelo engcwatshwe izinkulungwane noma izinkulungwane zamamitha ngaphansi komhlaba kuyimithombo ebalulekile engaphansi komhlaba. La magugu kawoyela ambiwa ngamadwala ambiwa phansi ngezingqimba zikawoyela ezingaphansi komhlaba ngezindleko ezinkulu. Enqubweni yokukhiqiza yesikhathi eside, imithombo yamafutha namanzi ilokhu ithinteka ngokugeleza kwamafutha negesi, ukuze imithombo kawoyela ishintshe ngaso sonke isikhathi, kancane kancane iguge, futhi izinhlobo ezihlukahlukene zokwehluleka zenzeka, okuholela ekuhlulekeni kokujwayelekile. ukukhiqizwa kwemithombo kawoyela namanzi. Ngisho kuyekwa. Ngakho-ke, kuyadingeka ukwenza imisebenzi ye-downhole emithonjeni yamafutha namanzi enezinkinga nokuhluleka, ukuze kubuyiselwe ukukhiqizwa okuvamile kwemithombo yamafutha namanzi. Imisebenzi ye-downhole ikakhulukazi ihlanganisa ukugcinwa kwemithombo kawoyela namanzi, ukulungiswa kabusha kwemithombo kawoyela namanzi, ukwakhiwa kabusha kwamachibi kanye nokuhlolwa kukawoyela.
2. Umsebenzi wokunakekela
Enqubweni yokukhiqiza uwoyela kanye nokujova amanzi emithonjeni kawoyela namanzi, ngenxa yokukhiqizwa kwesihlabathi nosawoti, ukungcwatshwa kokwakheka, ukunamathela kwesihlabathi sepompo, ukunamathela kukasawoti, noma ukugqwala kwentambo yepayipi, ukugqwala kwe-valve yepompo, ukwehluleka kwepacker, ukubhobhoza, ukupompa uwoyela. Ngenxa yezizathu ezihlukahlukene ezifana nokuphuka kwezinduku, imithombo yamafutha namanzi ayikwazi ukukhiqizwa ngokujwayelekile. Inhloso yokugcinwa kwemithombo kawoyela namanzi ukubuyisela ukukhiqizwa okuvamile kwemithombo kawoyela namanzi ngokusebenza nokwakha.
Ukugcinwa komthombo kawoyela namanzi kuhlanganisa: umjovo wokuhlola umthombo wamanzi, ukushintshwa kwezigxivizo, ukulinganisa iphrofayili yokumuncwa kwamanzi; ukuhlolwa kwepompo yomthombo kawoyela, ukuhlanzwa kwesihlabathi, ukulawula isihlabathi, ukukhuhla i-wax ye-casing, ukuxhunywa kwamanzi kanye nokwelashwa okulula kwengozi yemigodi kanye neminye imisebenzi yokusebenza.
Iphampu yokuhlola umthombo kawoyela
Lapho ipompo yomthombo wamafutha isebenza emthonjeni, ihlaselwa isihlabathi, i-wax, igesi, amanzi kanye nemithombo ethile elimazayo, ezolimaza izingxenye zepompo, ibangele ukuhluleka kwepompo, futhi umthombo wamafutha uzoyeka ukukhiqizwa. Ngakho-ke, ukuhlola ipompo kuyindlela ebalulekile yokugcina ukusebenza kahle kwepompo nokugcina ukukhiqizwa okuvamile kokupompa kahle.
Okuqukethwe okuyinhloko kwephampu yokuhlola umthombo kawoyela ukuphakamisa nokwehlisa induku yokuncelisa kanye nepayipi likawoyela. Umfutho we-reservoir awuphezulu, futhi isisetshenziswa sokuhosha singasetshenziselwa ukusebenza emgodini. Emithonjeni enezinto eziwayo noma umfutho wokwakheka ophakeme kancane, amanzi anosawoti noma ahlanzekile angasetshenziswa ekusebenzeni kwemigodi ngemuva kokucindezelwa komthombo, futhi ukubulawa kodaka kufanele kugwenywe.
Kufanele kuqashelwe ngokukhethekile umsebenzi wokuhlola iphampu: ukubala okunembile kokujula kwepompo, inhlanganisela enengqondo yama-sucker rods namashubhu, kanye nokugijima ama-sucker rods, amashubhu namaphampu omthombo ajulile, njll., okuyizinyathelo ezibalulekile zokuthuthukisa ukusebenza kahle kwepompo.
Umjovo wamanzi wase-Oilfield
Umjovo wamanzi we-Oilfield uyindlela ephumelelayo yokugcina umfutho wengqimba kawoyela, kanye nesilinganiso esisebenzayo sokugcina ukukhiqizwa okuzinzile nokuphakama okuphezulu ezindaweni zikawoyela, ukwandisa isivinini sokubuyisela uwoyela kanye nezinga lokugcina lokutakula.
Ngemva kokunqunywa kohlelo lokuthuthukisa umjovo wamanzi endaweni kawoyela, ukuze kutholwe ulwazi olufanele njengokucindezela komjovo kanye nevolumu yomjovo wengqimba yomjovo ngamunye, isigaba sokujova esivivinyweni kufanele sidlule ngaphambi komjovo wamanzi osemthethweni.
Umjovo wokuvivinya: ngaphambi kokuba umthombo kawoyela ufakwe ngokusemthethweni emjovweni wamanzi, ukuhlolwa kanye nenqubo yokwakhiwa komjovo womthombo omusha noma umjovo wokudlulisa umthombo kawoyela ubizwa ngokuthi umjovo wokuvivinywa. Ngokukhethekile emthonjeni womjovo wamanzi, ukukhipha ikhekhe lodaka, imfucumfucu, nokungcola odongeni lomthombo nangaphansi komthombo omusha noma uwoyela ngaphambi komjovo, bese unquma inkomba yokumunca amanzi yomjovo wamanzi kahle, ukubeka kahle. isisekelo esihle sokuqaliswa kohlelo lokujova amanzi. Umjovo wokuvivinya uhlukaniswe izigaba ezintathu, okuyi-drainage yamanzi, ukugeleza kwamanzi, umjovo wokudlulisa kanye nezinyathelo ezengeziwe zomjovo ezidingekayo.
Ukuvinjwa kwamanzi okukhethekile
Enqubweni yokuthuthukiswa kwendawo kawoyela, amanzi aphuma ongqimbeni lukawoyela azophazamisa kakhulu umsebenzi wokuthuthukiswa kwendawo kawoyela, futhi anciphise ngisho nenani lokugcina lokubuyisela endaweni kawoyela. Ngemva kokuba umthombo kawoyela ukhiqize amanzi, okokuqala thola izinga lamanzi, bese usebenzisa indlela yokuvala amanzi ukuze uvale. Inhloso yokuxhunywa kwamanzi ukulawula ukugeleza kwamanzi ongqimbeni olukhiqiza amanzi nokuguqula indlela yokugeleza kwamanzi kuwoyela okhukhula emanzini, ukuthuthukisa ukusebenza kahle kwezikhukhula zamanzi, nokuzama ukwenza ukukhiqizwa kwamanzi endaweni kawoyela kwehle noma uzinzise isikhathi esithile, ukuze kugcinwe ukwanda kokukhiqizwa kukawoyela noma ukukhiqizwa okuzinzile kanye nokuvuselelwa kokugcina kwendawo kawoyela.
Ubuchwepheshe bokuvala amanzi bungahlukaniswa ngezigaba ezimbili: ukuvala amanzi ngomshini kanye nokuvala amanzi ngamakhemikhali. Ukuvala amanzi ngekhemikhali kufaka phakathi ukuvala amanzi okukhethekile kanye nokuvala amanzi okungakhethi kanye nokulungiswa kwephrofayili yokumuncwa kwamanzi emithonjeni yokujova amanzi.
1.Ukuxhunywa kwamanzi ngomshiniukusebenzisa amapaki kanye namathuluzi asekela i-downhole ukuze uvale ungqimba lokuphuma kwamanzi emthonjeni wamafutha. Lolu hlobo lokuvala amanzi alunakho ukukhetha. Ngesikhathi sokwakha, intambo yepayipi kufanele ifakwe ukwenza isivalo sesihlalo sepacker sinembile futhi siqine, ukuze kufezwe inhloso yokuvala amanzi. Le ndlela yokuvimbela amanzi ingavala ungqimba olungaphezulu ukuze imbe ungqimba olungezansi, ivale ungqimba olungezansi ukuze imayini ungqimba olungaphezulu, noma ivale ungqimba oluphakathi ukuze imayini yomibili imikhawulo futhi ivale iziphetho ezimbili ukuze imayini ungqimba oluphakathi.
2.Ukuxhunywa kwamanzi amakhemikhaliukujova i-ejenti yokuxhuma amakhemikhali ongqimbeni lokuphuma kwamanzi, futhi usebenzise izakhiwo zamakhemikhali ze-ejenti yokuxhuma noma izinto ezidalwe ukushintsha kwezinto ezisabela ngamakhemikhali ekwakhekeni ukuze kuvalwe imigudu yokuphuma kwamanzi yokwakheka nokunciphisa ukunqanyulwa kwamanzi okuphelele umthombo wamafutha.
Ukuxhunywa kwamanzi okukhethekile ukukhipha amanye ama-polymer aphezulu e-molecular noma ezinye izinto ezingaphili ezishona phansi futhi ziqine lapho zihlangana namanzi ekwakhekeni. Isakhi sofuzo se-hydrophilic ku-polymer sinokuhambisana kanye nokukhanga emanzini lapho sihlangana namanzi, futhi siyakhula; liyashwabana lapho lihlangana namafutha, futhi alinawo umphumela we-adsorption. Izinto ezingaphili ezakha imvula nokuqina lapho zihlangana namanzi zingavimba umzila wokuphuma kwamanzi wokwakheka, futhi ngeke zikhiqize imvula noma ukuqina lapho zihlangana namafutha.
Ukuvala amanzi angakhethi ikakhulukazi kuncike ezinhlayiyeni ze-sedimentation ukuvimba ama-pores okwakheka. Le ndlela yokuxhuma amanzi ayivimbi kuphela umzila wamanzi, kodwa futhi ivimbela umzila wamafutha.
Ukulungiswa kabusha kwemithombo kawoyela
Enqubweni yokukhiqiza imithombo kawoyela, ngokuvamile ngenxa yezingozi zemigodi kanye nezinye izizathu, imithombo kawoyela namanzi ayikwazi ukukhiqizwa ngendlela evamile, ikakhulukazi ngemva kokwenzeka kwezinto ezinamathelayo neziwayo, ukukhiqizwa kwemithombo kawoyela namanzi kuzoncishiswa noma kumiswe. , futhi ezimweni ezimbi kakhulu, imithombo kawoyela namanzi izochithwa. Ngakho-ke, kuyisinyathelo esibalulekile sokuqinisekisa ukukhiqizwa okuvamile kwendawo kawoyela ukuvimbela ukwenzeka kwezingozi zemigodi ephansi futhi ukubhekana nazo ngokushesha. Okuqukethwe okuyinhloko kokulungiswa kabusha kwemithombo kawoyela namanzi kuhlanganisa: ukuphatha ingozi yemigodi engaphansi, ukuhlengwa kwento ewayo eyinkimbinkimbi, ukulungiswa kwebhokisi, ukuchezuka, njll.
Ukulungiswa kabusha kwemithombo kawoyela namanzi kuyinkimbinkimbi, kunzima, futhi kufuna kakhulu ngobuchwepheshe. Ngaphezu kwalokho, kunezizathu eziningi zezingozi zemigodi, futhi kunezinhlobo eziningi zezingozi zemigodi. Izingozi ezivamile zamapayipi angaphansi ngokuvamile zihlukaniswa zibe izigaba ezintathu: izingozi zobuchwepheshe, izingozi zamapayipi avaleleke emgodini kanye nezingozi zezinto eziwayo. Lapho ubhekana nakho, kuyadingeka ukuthola uhlobo lwengozi, uthole imbangela yengozi, futhi uthathe izinyathelo zobuchwepheshe ezihambisanayo zokuyiphatha kahle. Zonke izingozi zobuchwepheshe zenqubo zenzeka phakathi nenqubo, futhi zingase zisetshenzwe kusengaphambili ngokwembangela yengozi phakathi nenqubo yokwakha. Izingozi zokunamathela emigodini kanye nezingozi zezinto eziwa phansi yizingozi ezinkulu zemigodi ezithinta ukukhiqizwa okuvamile kwemithombo kawoyela namanzi. INGOZI. Futhi kuyinani elikhulu lezingozi ezivamile ezingaphansi komhlaba.
