Imikhiqizo
Ithuluzi lokugaya le-API 7-1 Casing Section
Iphrofayela yomkhiqizo
I-Section mill uhlobo lwethuluzi lokuvula ifasitela le-casing elihlanganisa imisebenzi yokusika i-casing kanye ne-milling. I-section mill ingena e-casing kanye ne-BHA, bese inquma i-casing endaweni ekhethiwe kuqala. Ngemva kokuba i-casing isiqediwe ngokuphelele, izogaywa ngqo kusuka kulesi sikhundla. Ngemva kokufinyelela ekujuleni okuthile, umsebenzi wokuvula ifasitela le-casing usuqediwe. I-section mill inezinzuzo zesakhiwo esilula, ukusebenza okulula ukuyenza ithuluzi lokuvula ifasitela le-casing elisebenza kahle kakhulu.
Okwamanje, umshini wokugaya izingxenye ungacindezela futhi ufake usimende ekusebenzeni kokulahla umthombo, okungenza usimende uxhumane ngqo nokwakheka ebangeni elide ngaphakathi kwama-degree angu-360. Usimende ungangena echibini ngokuya ngezimbobo ezikhona kanye nokuqhekeka kokwakheka, futhi umphumela wokuxhuma ungcono kakhulu kunowokucindezela usimende ngemva kokubhoboza.
Isimiso sokusebenza
Ngemva kokuba umshini wokugaya izingxenye wehliswe endaweni ekhethiwe ebhokisini kanye ne-BHA, qala itafula elijikelezayo, uvule ipompo, i-piston esethuluzini icindezelwa phansi yingcindezi, ikhoni engezansi ye-piston isunduza ama-cutting blades avuleke bese ilungisa imbobo evulekile. Lapho ama-cutting blades evuleka ngobubanzi obukhulu, ukulungiswa kwembobo evulekile kuqediwe. Ngaphansi kwengcindezi yepompo eqhubekayo, i-blade ingavulwa futhi ilungiswe kabusha imbobo ngqo. Ngemva kokuba ipompo imisiwe, i-piston iyasethwa kabusha ngaphansi kwesenzo sentwasahlobo futhi ama-cutting blades azohoxiswa ngokuzenzakalelayo.
Izici zomkhiqizo
(1) Umklamo wemishini, isakhiwo esilula kanye nokusebenza okulula
(2) Ingcindezi yokuqalisa ephansi kanye namandla amakhulu okusekela ama-blade kuyasiza ekusikeni i-casing;
(3) Umklamo wentwasahlobo onamandla aphezulu usiza ukuhoxisa ngokuzenzakalelayo umshini wokusika ngemva kokusika;
(4) Ukwakheka kwe-stop block kanye ne-pin kuyasiza ekuphoqeleleni ukuhoxiswa kwethuluzi;
(5) I-blade inokukhula okukhulu futhi ingasetshenziswa ku-casing efanayo enobukhulu obuhlukene bodonga;
(6) I-blade yenziwe nge-tungsten carbide esezingeni eliphezulu kanye ne-Bake hughes inqubo efanayo yokushisela, enekhono eliphezulu lokusika kanye nokuphila isikhathi eside kwenkonzo.
Ithebula Losayizi Wesigayo Sesigaba
Amathuluzi okufanisa - Isigayo se-taper sezinga eliphezulu
Amathuluzi okugaya wonke enziwe nge-tungsten carbide alloy esezingeni eliphezulu kanye nobuchwepheshe obufanayo bokushisela bukaBaker Hughes. Inhloso yalolu chungechunge lwezigayo ukubuyisela ngokuphelele ukukhethwa kwezinto, ukwakheka kwesakhiwo kanye nenqubo yokushisela kaBaker Hughes, ukuze kufezwe ikhwalithi efanayo yomkhiqizo kaBaker Hughes.
2. Iphrofayili yokugaya ipompo yekilasi eliphezulu
ingakhiqiza umshini wokugaya wezinga eliphezulu one-diameter yangaphandle engu-76 mm kuya ku-445 mm. Insimbi ye-alloy esezingeni eliphezulu isetshenziswa njengomzimba oyinhloko, okuvumela ukucutshungulwa kwemigodi yamanzi emikhulu ukuqinisekisa ukukhishwa okubushelelezi kwemfucumfucu yokugaya. Ngesikhathi esifanayo, ngokwezidingo ezithile zamakhasimende, isakhiwo somkhiqizo singaklanywa ukuze kufezwe ukusebenza okuhle kakhulu kokusetshenziswa.
3. Ithebula losayizi we-Taper mill
Isakhiwo somkhiqizo
1. Isigayo sesigaba sihlanganisa ikakhulukazi izingxenye ezilandelayo: ilunga eliphezulu, umzimba oyinhloko, i-piston, umlomo, ama-cutting blades kanye ne-guide cone, njll.
III. Izinzuzo zobuchwepheshe zePetrozhr section mill
1. Kukhiqizwe nge-tungsten carbide esezingeni eliphezulu
Ama-blade okugaya akhiqizwa yinkampani yethu anezinzuzo ezilandelayo:
(1) Imisebenzi yokugaya nokusika ishesha kakhulu kunezinsika ezivamile;
(2) Nciphisa ingcindezi yokubhoboza edingekayo ekusikeni;
(3) Amamaki amazinyo ayalingana futhi akukho ndawo ephumayo;
(4) Imfucumfucu ekhiqizwayo iyafana kakhulu;
(5) Ubulukhuni bezinto zokusetshenziswa buphakeme futhi isakhiwo siyafaneleka. Uma kusebenza, kusika insimbi kunokugaya insimbi.
2. Ukuhlolwa kwezinto zokusetshenziswa okuqinile
I-tungsten carbide ekhethwe yinkampani yethu izothunyelwa enhlanganweni yokuhlola yobungcweti ukuze ihlolwe ngemva kokufika kwebhetshi ngayinye. Ukuqinisekisa ukuthi ubulukhuni be-alloy nezinye izinkomba ziyahlangabezana nezidingo zokukhiqiza zenkampani.
3. Inqubo ephelele yokushisela
Siqasha owayengumshiseli omkhulu we-Baker Hughes futhi sikhetha amathuluzi afanayo okushisela kanye nezinto ezisizayo eshabhu likaBaker Hughes ukuze sikhiqize ubuchwepheshe bokushisela be-Becker enqubweni nasemishinini.
Ukuze sinciphise ukuguquguquka kwamathuluzi ngenxa yezinguquko zokushisa ngaphambi nangemva kokushisela, sisungula uhlelo lokuvikela ukushisela ukuqinisekisa ukuzinza kwe-geometry yomkhiqizo kanye nokusebenza kahle komsebenzi.
Inqubo yokusebenza kwesigayo sesigaba se-IV.
Ukulungiswa kwembobo yomgodi:
1. Lungisa i-casing. Lungisa i-downhole casing nge-taper mill noma i-casing shaper.
2. Ukuhlanza Imithombo. Geza uwoyela ongahluziwe noma olunye uketshezi oluvela emthonjeni ngamanzi ahlanzekile.
3. Ukuklwebha noma imbobo yomthombo. Ukuklwebha nokuklwebha amapayipi kufanele kwenziwe nge-scraper ejwayelekile kanye nobubanzi bokuklwebha kuze kube ngamamitha angama-20 ngaphansi kwendawo yokugaya ingxenye.
4. Lungisa uketshezi lokugaya. Izakhiwo zalo ezahlukahlukene zingaqinisekisa ukuthi luyakwazi ukuthwala kahle imfucumfucu.
Ukuhlolwa komhlabathi:
1. Hlola ukuthembeka kwamathuluzi;
2. Ushintsho lomfutho wephampu luyahlolwa lapho kuvulwa ama-cutting blades, okunikeza isisekelo sokwahlulela ukuthi ngabe i-downhole casing isinqunyiwe ngokuphelele.
Ukukhetha indawo yokugaya:
1. Usimende ongaphandle kwebhokisi lokugaya lesigaba kufanele ufakwe usimende kahle.
2. Gwema indawo lapho i-casing inokuphazamiseka kanye nokuguquguquka. Uma kukhona indawo enjalo, umsebenzi kufanele wenziwe ngamamitha angu-30-40 ngaphezu kwendawo. Futhi indawo yokuqala yokusebenza kokusika kufanele ibe ngamamitha angu-1-3 ngaphezu kwendawo yokuxhuma eseduze.
3. Iphakethe kufanele ligcinwe ngaphansi komgodi. Ngokuvamile, ubude bephakethe kufanele bube ngaphezu kwamamitha ayi-100.
Ukusika i-casing:
① Ngemva kokuxhuma ithuluzi ku-BHA bese wehla uye endaweni yokugaya ingxenye, qala itafula elijikelezayo ukuze unqume indawo yokuhlanganisa ikhesi ngokwerekhodi lekhesi (logging), bese wehlisa ithuluzi libe cishe yi-1-3m ngaphezu kwekhesi eliseduze nelihlanganisiwe kanye nebhuleki.
② Qala itafula elijikelezayo kuqala, wandise isivinini sokujikeleza sibe ngu-50-60r / min, qala iphampu, wandise kancane kancane ukuhamba, ukuze ingcindezi yephampu ikhuphuke. Ngalesi sikhathi, ingcindezi yephampu iyanda kusukela kokuncane kuya kokukhulu, iyanda kancane kancane ibe ngu-10-12mpa.
③ Qhubeka usika i-casing imizuzu engama-20-45. Uma ingcindezi yepompo yehla ngokuzumayo ngo-2-5mpa, i-casing iyanqunywa. Ukuze umzimba wokusika uvuleke ngokuphelele, gcina indawo yokusika kule ndawo imizuzu engama-30 ngemva kokusika, bese ukhulisa kancane kancane ukuhamba ukuze uqinisekise ukwakheka okugcwele kokuqhekeka.
Ibhokisi lokugaya:
I-WOB ingandiswa kancane kancane ngemva kokuba i-casing isinqunyiwe. Elawulwa phakathi kuka-10-25kn, ijubane elijikelezayo liyandiswa libe ngu-80-120r / min, futhi ingcindezi yepompo ilawulwa ngaphakathi kwe-10MPa ukuqinisekisa ukuthi ukuhamba okujikelezayo kungathwala imfucumfucu yensimbi. Uma ingxenye ngayinye ingama-0.5m, ingabholwa ngemitha eli-1 ukuze kuhlanganiswe futhi kujikelezwe, ukuze kube lula ukuthi imfucumfucu yensimbi egaywe kusukela engxenyeni ibuye kahle nge-annulus. Ngemva kwemijikelezo yemijikelezo engu-1-2, bhoboza futhi ukuze uqhubeke nokwakha nokugaya.
[Kule nqubo, kuyadingeka ukulungisa kahle ukusebenza kodaka ngenkathi kwandiswa ukufuduka; ngesikhathi esifanayo, hambisa kahle ithuluzi lokubhoboza bese ulungisa ukujikeleza kwegazi ukuze wenze ama-chip ensimbi abuye ngokugcwele futhi kuvimbele ukunqwabelana kwemfucumfucu]
