ethula:
Ubuchwepheshe bokufaka uwoyela we-polymer kahle busetshenziswe kabanzi ekuhloleni nasekuthuthukisweni kwezizinda zikawoyela negesi.Enye yezingxenye ezibalulekile kubuchwepheshe be-polymer cementing yi-ejenti elwa nokulahlekelwa kwamanzi, enganciphisa izinga lokulahlekelwa kwamanzi ngesikhathi senqubo yokufaka usimende.Ukusetshenziswa kobuchwepheshe besimende we-polymer kunezinzuzo eziningi njengamandla aphezulu, ukungena kancane, nokusebenza okuhle kakhulu kokuvala.Kodwa-ke, inkinga evamile ehlangabezane nayo kule nqubo ukulahlekelwa kwamanzi, okungukuthi, i-slurry ye-cement ingena ekubunjweni, okwenza kube nzima ukukhipha ithubhu ngesikhathi sokubuyiselwa kwamafutha.Ngakho-ke, ukuthuthukiswa kwesinciphisi sokulahlekelwa kwamanzi okushisa aphakathi nendawo nesiphansi sekugxilwe ekuqhubekeleni phambili kobuchwepheshe bokufaka usimende endaweni kawoyela.
I-polymer oil well-cement fluid loss reducer:
Isengezo sokulahlekelwa uketshezi siyinto esetshenziswayo esetshenziswayo ekulungiseni udaka lukasimende.Kuyimpushana encibilika kalula emanzini futhi enezinto ezinhle zokuxuba.Ngesikhathi sokwakhiwa, ama-ejenti okulawula ukulahlekelwa kwamanzi ahlanganiswa nezinye izingxenye ukuze enze udaka lukasimende olulinganayo futhi oluzinzile.I-ejenti yokulawula ukulahlekelwa uketshezi idlala indima ebalulekile ekwehliseni izinga lokulahlekelwa uketshezi ngesikhathi senqubo yokufaka usimende.Inciphisa ukufuduka kwamanzi odakeni kuya ekwakhekeni okuzungezile futhi ithuthukise izakhiwo zemishini zikasimende.
Ukulahlekelwa kwamanzi ≤ 50:
Uma usebenzisa ama-ejenti okunciphisa ukulahlekelwa uketshezi, kubalulekile ukulawula izinga lokulahlekelwa uketshezi phakathi kwebanga elithile, ngokuvamile elingaphansi noma elilingana no-50ml/30min.Uma izinga lokulahlekelwa kwamanzi liphezulu kakhulu, udaka lukasimende luyongena ekwakhekeni, lubangele ukugeleza kwemigodi, udaka, nokwehluleka kukasimende.Ngakolunye uhlangothi, uma izinga lokulahlekelwa kwamanzi liphansi kakhulu, isikhathi sokumisa sizokwandiswa, futhi i-ejenti eyengeziwe yokulwa nokulahlekelwa kwamanzi iyadingeka, okwandisa izindleko zenqubo.
Isinciphisi sokulahlekelwa kwezinga lokushisa elimaphakathi neliphansi:
Phakathi nenqubo yokufaka usimende ezindaweni zikawoyela, izinga lokulahlekelwa kwamanzi lithintwa izici ezihlukahlukene ezifana nezinga lokushisa lokubunjwa, ukucindezela, nokungena kwamanzi.Ikakhulukazi, izinga lokushisa le-cementing fluid linomthelela omkhulu ekulahlekelweni kwamanzi.Ukulahlekelwa uketshezi kuvame ukwanda kakhulu emazingeni okushisa aphezulu.Ngakho-ke, enqubweni yokufaka usimende, kuyadingeka ukusebenzisa izithasiselo zokulahlekelwa kwamanzi okushisa okuphakathi nendawo neziphansi ezinganciphisa izinga lokulahlekelwa uketshezi emazingeni okushisa aphezulu.
Ngokufigqiwe:
Ngamafuphi, ubuchwepheshe bokufaka uwoyela we-polymer kahle sebungomunye wobuchwepheshe obubalulekile bokuhlola nokuthuthukiswa kwendawo kawoyela negesi.Enye yezingxenye eziyinhloko zalobu buchwepheshe i-ejenti elwa nokulahlekelwa kwamanzi, edlala indima ebalulekile ekwehliseni izinga lokulahlekelwa kwamanzi phakathi nenqubo yokufaka usimende.Ukulawulwa kokulahlekelwa kwamanzi ngesikhathi sokulungiswa kodaka nakho kudlala indima ebalulekile ekuqinisekiseni impumelelo yenqubo yokufaka usimende.Ukuthuthukiswa kwezinciphisi zokulahlekelwa kwamanzi okushisa okuphakathi nendawo naphansi kubaluleke kakhulu ekuthuthukiseni ukusebenza kahle kukasimende, ukunciphisa izindleko kanye nokwenza ngcono ubuqotho bemithombo kawoyela negesi.
