Ibhuloho lesihlabathi sokumba libhajwe kanye nokwelashwa kwengozi

Ukunamathela kwebhuloho lesihlabathi kubuye kubizwe ngokuthi ukuzinza kwesihlabathi kubhajwe, imvelo yaso ifana nokubhidlika, futhi ukulimala kwayo kubi kakhulu kunokunamathela unamathele.

1.Isizathu sokwakheka kwebhuloho lesihlabathi

(1) Kulula ukwenzeka lapho kubholwa ngamanzi ahlanzekile ngendlela ethambile;
(2)I-surface casing incane kakhulu, futhi i-soft stratum ivezwa kakhulu;
(3) Ukwengeza i-flocculant ngokweqile oketshezini lokumba;
(4)isivinini sokumba imishini siyashesha, ukugudluza uketshezi lokumba akukwazi ukuqhubeka;
(5)Shintsha uketshezi lokuqala lokumba emthonjeni, noma ushintshe kakhulu ukusebenza koketshezi lokumba;

Into yokunamathela kwebhuloho lesihlabathi

(1) Alukho uketshezi lokumba olubuyiselwa ekhanda lomthombo ngesikhathi sokumba noma uketshezi lokumba lubuyiselwa emuva ku-tubhoboza ipayipi;

(2) Ukumelana kwamathuluzi okubhola kuwukumelana okuthambile, futhi akukho ukumelana okungazelelwe pamafutha;

(3) Uma ibhuloho lesihlabathie kwenzeka ngesikhathi sokumba, izinga le-annulus liquid liyehla, futhi izinga le-liquid emgodini wamanzi wethuluzi lokumba lehla ngokushesha;

(4) Ngemva kokuba ithuluzi lokumba lingene ebhulohweni lesihlabathi, ngaphambi kokuba iphampu iqalwe, ukunyakaza okuya phezulu naphansi nokujikeleza kukhululekile. Uma ipompo izoqalwa, umfutho wepompo uzokhuphukase, isisindo esimisiwe sizokwehla, futhi uketshezi lokumba ngeke lubuyele noma lubuyele kancane kakhulu emthonjeni;

5 ikakhulukazi akukho okuqinile kwesigaba sokumba uketshezi, lokhu kwenzeka kakhulu.

Ukuvimbela ibhuloho lesihlabathi elinamathele

(1) Kungcono ukungabholi ngamanzi;

(2)Engxenyeni yembobo evulekile, isikhathi sokumba uketshezi lokuphumula akufanele sibe side kakhulu;

(3) Ukwenziwa ngcono kwe-drukwakheka kwe-fluid egulayo;

(4) Lapho kubholwag, inani elifanele lepompo kufanele likhethwe ngokuya nezici zokubunjwa;

(5) Ukugcina ukuzinza kohlelo loketshezi lokumba nokusebenza.

Ukwelashwa kwebhuloho lesihlabathi elinamathele

(1) Uma i-drilling fli-uid ingangena empompini kuphela, ithuluzi lokubhoboza libhajwe, futhi alikwazi ukususwa, kufanele kubalwe indawo yephoyinti lekhadi, futhi isikhathi kufanele sibuyiselwe emuva ukusuka eduze kwephoyinti lekhadi.

(2) Isikhundla sokwakheka kwebhuloho lesihlabathi singase sibe yingxenye engaphezulu noma engxenyeni engezansi, kodwa ingxenye yayo yomthombo ayikude kakhulu, futhi akunakwenzeka ukungcwaba wonke amathuluzi okumba. Uma ibhuloho lesihlabathi lisengxenyeni engenhla, nakuba engekho amathuluzi amaningi okubhoboza athululwe okokuqala, akunakwenzeka ukusebenzisa umshini omude wokugaya umgqomo ukuze ususe ibhuloho lesihlabathi, bese ithuluzi lokubhoboza lisenkinobho buyisela ukujikeleza, futhi kamuvaizinto kulula ukuzenza. Uma ibhuloho lesihlabathi lisengxenyeni engezansi, indlela yokuqhumisa i-backbuckle evulekile kufanele isetshenziselwe ukuthulula ithuluzi lokubhoboza elingamile ngesikhathi, futhi ithuluzi lokubhola elilandelayo lingakhishwa kuphela ngokugaya i-backbuckle.

(3) Ibhuloho lesihlabathi lokubhoboza ibhuloho elinamathelayo livame ukwenzeka ngesikhathi sokukhubeka, i-drill ayikho ngaphansi komgodi, ngakho-ke inqubo yokugaya, izinhlanzi zingase zicwile, kulokhu, kufanele kufakweiately on inkinobho, ithuluzi sokubhoboza, kungenzeka ukukhulula ikhadi in the umsebenzi. Uma singakwazi futhi ukujikeleza uketshezi lokumba, zonke izinkinga zizoxazululeka.

(4) Uma intambo yokubhoboza ifakwe i-centralizer, ibhuloho lesihlabathi livame ukuba ngaphezu kwe-centralizer yokugcina, ngakho-ke emva kokugaya i-casing kuya ku-centralizer, akudingekile ukuphinda ugaye i-centralizer, futhi imbiza inganyakaziswa futhi. ungabambeki.
