Ukuthuthukisa Ikhono Lokubhoboza Ngokusebenzisa I-Lightweight Drilling Fluids kanye nama-Hollow Glass Microspheres

Emhlabeni wokuhlolwa kukawoyela negesi, ukuphishekela ukusebenza kahle kanye nokuphumelela kwezindleko kuyinto eqhubekayo. Enye yezindawo ezibalulekile lapho ukuqamba okusha kunomthelela omkhulu ukuthuthukiswa koketshezi lokumba olulula. Lawa manzi ayisipesheli adlala indima ebalulekile enqubweni yokumba futhi anikezela ngezinzuzo eziningi ezisiza ukwandisa ukusebenza kahle kanye nokunciphisa umthelela wendawo. Eminyakeni yamuva nje, ukungezwa kwama-microspheres engilazi angenalutho njengama-fillers oketshezini lokumba olulula kuye kwavela njengesixazululo esisebenza kahle esinikeza isethi eyingqayizivele yezinzuzo futhi silungisa kabusha indlela yemboni yokumba imisebenzi.

Kuyini uketshezi lokumba olulula futhi luyini ukusetshenziswa kwalo?

Uketshezi lokumba olulula, olukwaziwa nangokuthi uketshezi olumbayo olunokuminyana okuphansi noma olusebenza kahle kakhulu, luwuketshezi olwakhiwe ngokukhethekile oluklanyelwe ukunciphisa umfutho we-hydrostatic okhishwa ekubunjweni ngesikhathi sokumba. Ukwehliswa kwengcindezi kusiza ekuvimbeleni ukungazinzi kwe-wellbore, ukungena kwamanzi, nezinye izinselele zokumba, ekugcineni kukhulise ukusebenza kahle kokumba nokunciphisa izindleko.

Lawa manzi ngokuvamile asetshenziswa ezimeni lapho uketshezi olujwayelekile lokumba lungaba nengcindezi eyeqile ekubunjweni, njengokumba kwamanzi ajulile, ukubhola okufinyelelekayo okunwetshiwe, kanye nokwakheka kokuphuka okuphansi kokuphuka.Ngokusebenzisa uketshezi lokumba olulula, ama-opharetha anganciphisa ingozi yokuwa kwe-wellbore, ukulahleka kokujikeleza kwegazi, kanye nokubambeka komfutho ohlukile, ngaleyo ndlela bathuthukise ukuphepha nempumelelo yokusebenza.

Kungani ama-microsphere engilazi angenalutho engaba izigcwalisi ezisebenza kahle kakhulu zoketshezi lokumba olulula?

Ingilazi encane microspheres baye bakhanga ukunaka njengobaizigcwalisi ezisebenza kahle kakhulu kuketshezi lokumba olulula ngenxa yezakhiwo zabo eziyingqayizivele zomzimba namakhemikhali. Ngokuvamile enziwe ngengilazi ye-borosilicate ye-soda-lime, lawa ma-microsphere anomthamo ophansi, amandla aphezulu, nokuma okuyisiyingi, okuwenza alungele ukuthuthukisa ukusebenza koketshezi lokumba.

Enye yezinzuzo eziyinhloko zeingilazi encane microspheres esetshenziswa oketshezini lokumba olulula yikhono lazo lokunciphisa ngokuphawulekayo ukuminyana okuphelele koketshezi ngaphandle kokuphazamisa ukusebenza kwalo. Ngokungeza lawa ma-microspheres, ama-opharetha angafinyelela ukuminyana koketshezi oludingekayo kuyilapho benciphisa okuqukethwe okuqinile, bethuthukisa izici ze-rheological, futhi bathuthukise ukuqina koketshezi.

Ngaphezu kwalokho, ama-microspheres engilazi angenalutho anamandla amakhulu okucindezela kanye nokuzinza kokushisa, okuwenza afaneleke kahle izimo ezinzima ezihlangatshezwana nazo ekusebenzeni kokumba. Imvelo yabo engasebenzi iqinisekisa ukuthi ukusebenzisana kwamakhemikhali noketshezi kuyancishiswa, ngaleyo ndlela kugcinwe ubuqotho boketshezi lokumba futhi kunciphise ingozi yokulimala kokubunjwa.

Uhlu lwezicaciso zengilazi ezingenalutho ezitholakalayo ukuze amakhasimende akhethe kuzo

Lapho ucubungula ukungezwa kweingilazi encane microspheres kuketshezi lokumba olulula, kubalulekile ukuhlola izidingo ezithile bese ukhetha umkhiqizo wobuhlalu ofaneleka kakhulu. Ukusiza ngale nqubo, amakhasimende kumele acabangele lezi zicaciso ezilandelayo:

1.Ukusabalalisa usayizi we-particle : Ukusatshalaliswa kosayizi wezinhlayiyana zama-microspheres engilazi angenalutho kudlala indima ebalulekile ekunqumeni ukuziphatha kwe-rheological nokulawula ukuminyana koketshezi. Amakhasimende kufanele ahlole ukusatshalaliswa kosayizi wezinhlayiyana ukuze aqinisekise ukuhambisana nezinto ezidingwayo zoketshezi lokumba.

2.Ukuminyana : Ukuminyana kwama-microsphere engilazi angenalutho kuthinta ngokuqondile ukuminyana okuphelele koketshezi lokumba. Ukukhetha ama-microsphere anokuminyana okufanele kubalulekile ukuze kuzuzwe ukuminyana koketshezi oludingekayo kuyilapho ugcina ukusebenza kahle.

3.Amandla nokuphihliza ukumelana : Amandla emishini nokumelana nokuchoboza kwama-microsphere engilazi angenalutho kuyizinto ezibalulekile zokucatshangelwa, ikakhulukazi ezindaweni zokumba ezinengcindezi ephezulu kanye nezishisa kakhulu. Amakhasimende kufanele abeke phambili ama-microsphere anamandla aphakeme ukuze aqinisekise ukuzinza nokwethembeka ngesikhathi sokumba.

4.Ukuzinza okushisayo : Ukuzinza okushisayo kwama-microsphere engilazi angenalutho kuyisici esibalulekile uma kucatshangelwa izimo zokushisa eziyinselele okuhlangatshezwane nazo ekubhobolweni. Ukukhetha ama-microsphere anokusimama okuhle kakhulu kwe-thermal kubalulekile ekugcineni ukusebenza koketshezi ngaphezu kwebanga lokushisa elibanzi.

5.Ukungangeni Kwamakhemikhali : Ukungangeni kwamakhemikhali kwama-microsphere engilazi angenalutho kubalulekile ekugcineni ubuqotho boketshezi lokumba kanye nokuvimbela ukusebenzisana okungalungile nezinye izingxenye zoketshezi noma ukwakheka ngokwako. Amakhasimende kufanele abeke phambili ama-microsphere ane-inertness yamakhemikhali efakazelwe ukuze anciphise ubungozi bokuthikameza kabi inqubo yokumba.

Sengiphetha, ukusetshenziswa koketshezi lokumba olulula oluthuthukiswa ukufakwa kwama-microsphere engilazi angenalutho kumelela inqubekelaphambili enkulu emkhakheni wobuchwepheshe bokubhola. Lezi zixazululo ezintsha zinikeza uhla lwezinzuzo eziphoqayo, okuhlanganisakuncishiswe umfutho we-hydrostatic, ukuqina kwe-wellbore okuthuthukisiwe, kanye nokusebenza okuthuthukisiwe okuthuthukisiwe . Ngokukhetha ngokucophelela ama-microsphere engilazi angenalutho anezincazelo ezifanele, o-opharetha bangalungisa uketshezi lokumba ukuze luhlangabezane nezidingo ezithile zezindawo zokumba ezihlukene, okugcine kube nesandla emisebenzini yokumba ephephile, engabizi kakhulu, kanye nebhekele imvelo.

Njengoba imboni iqhubeka nokuguquguquka, ukuhlanganiswa kwe-lightweight drilling fluids kanyeingilazi encane microspheres izodlala indima ebalulekile ekwenzeni ngcono ukusebenza kahle kanye nokusimama kuyo yonke imboni kawoyela negesi. Ikusasa lentuthuko eqhubekayo kubuchwepheshe bokumba liyathembisa njengoba imizamo yocwaningo nentuthuko eqhubekayo igxile ekuthuthukiseni ukusebenza nokuhlukahluka kwalezi zixazululo.

Singajabula kakhulu ukukusiza ngokuqhubekayo! Uma unentshisekelo, sicela ungangabazi ukusithinta ukuze uthole ukwesekwa okwengeziwe.
