Isengezo sokulahlekelwa uketshezi lwe-humic acid siwuhlobo lwesengezo sokulahlekelwa uketshezi lwe-polymer kahle esiye sathola ukuduma eminyakeni yamuva nje.Njengomunye wemikhiqizo emisha ye-Oilbayer, inkampani esebenza ngokukhethekile ku-R&D kanye nokukhiqizwa kwamakhemikhali e-oilfield, lesi sengezo sokulahlekelwa uketshezi siklanyelwe ukusiza abasebenzisa uwoyela negesi emzamweni wokukhiqiza okuphezulu nokusebenza kahle.
Lolu hlobo lwesithasiselo ngokuvamile lwenziwa ngenhlanganisela ye-AMPS/NN/humic acid enezinga lokushisa elihle kanye nokumelana nosawoti.I-humic acid isebenza njenge-monomer eyinhloko, kuyilapho amanye ama-monomers amelana nosawoti ahlanganiswa ukuthuthukisa ukusebenza kwawo.Umphumela uba isithasiselo esisebenza kahle kakhulu esingasiza ekunciphiseni ukulahlekelwa uketshezi ngesikhathi sokufakwa kukasimende kahle, ngaleyo ndlela kuthuthukiswe ukusebenza komthombo futhi kuthuthukiswe yonke imbuyiselo ekutshalweni kwezimali.
Ukulahlekelwa uketshezi kuyinkinga evamile embonini kawoyela negesi, ikakhulukazi ngesikhathi sokusebenza kukasimende.Kwenzeka lapho uketshezi olusetshenziselwa ukufaka usimende umthombo womthombo lungena ekwakhekeni kwamadwala, kushiye izikhala ezinciphisa amandla esibophezelo sikasimende.Lokhu kungaholela ezinkingeni eziningi, njengokuncishiswa kokukhiqiza, ukukhuphuka kwezindleko zokunakekela, kanye nezinkinga zobuqotho bemithombo.
Isengezo sokulahlekelwa uketshezi lohlobo lwe-humic acid sisiza ekwehliseni lezi zinkinga ngokwakha ungqimba oluvikelayo oluzungeze umthombo.Lolu ungqimba lusebenza njengesithiyo, luvimbele uketshezi lukasimende ukuthi lungangeni ekwakhekeni futhi lunciphise inani loketshezi olulahlekayo ngesikhathi sokusebenza kukasimende.Lokhu kufezwa ngenhlanganisela yezinto eziyingqayizivele ze-polymer, esiza ekwandiseni i-viscosity yoketshezi lukasimende futhi luvimbele ukuthi lungagelezi emgodini womthombo.
Enye yezinzuzo eziyinhloko zokusebenzisa izithasiselo zokulahlekelwa kwamanzi ohlobo lwe-humic acid ukushisa kwazo okuhle kakhulu nokumelana nosawoti.Lokhu kusho ukuthi zingasetshenziswa ezindaweni eziningi ezihlukene, okuhlanganisa ukwakheka kwezinga lokushisa eliphezulu kanye nalezo ezinosawoti omningi.Lokhu kuguquguquka kubenza babe yinketho ekahle kubaqhubi bakawoyela negesi abafuna ukukhulisa ukusebenza kahle nokukhiqiza kwemisebenzi yabo yokumba.
Sengiphetha, isengezo sokulahlekelwa uketshezi lohlobo lwe-humic acid siyisixazululo esisha sezinkinga zokulahlekelwa uketshezi ezitholwa imboni kawoyela negesi.Ithuthukiswe i-Oilbayer, lo mkhiqizo uhlanganisa izinzuzo eziyingqayizivele ze-AMPS/NN/humic acid namanye ama-monomers amelana nosawoti ukuze kwakhe isithasiselo esisebenza kahle kakhulu esingasetshenziswa kuzinhlelo zokusebenza eziningi.Uma unentshisekelo yokuthuthukisa ukukhiqiza nokusebenza kahle kwemisebenzi yakho yokumba, cabanga ukufaka isengezo sokulahlekelwa uketshezi lohlobo lwe-humic acid emisebenzini yakho yokufaka usimende.
ISINCISHI SOKULAHLEKELA OKUPHAKATHI KANYE NESIPHANSI
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.
