Cement Casing Rubber Plug for oilfield
Incazelo:
Ipulaki yenjoloba isetshenziselwa ukuhlukanisa udaka lukasimende kolunye uketshezi, ukunciphisa ukungcoliswa kanye nokugcina ukusebenza okunodaka okubikezelwayo.Izinhlobo ezimbili zamapulaki o-cementing ngokuvamile asetshenziswa ekusebenzeni kukasimende.Ipulaki engezansi yethulwa ngaphambi kodaka lukasimende ukuze kuncishiswe ukungcoliswa uketshezi olungaphakathi kwekesi ngaphambi kokuhlanganisa usimende.I-diaphragm emzimbeni wepulaki iyaphuka ukuvumela udaka lukasimende ukuthi ludlule ngemva kokuba ipulaki ifinyelele kukhola yokumisa.
Ipulaki ephezulu inomzimba oqinile onikeza inkomba enhle yokuthinta ikhola yokumisa kanye nepulaki engezansi ngokukhuphuka komfutho wepompo.
Amapulagi okufaka usimende ayingxenye ebalulekile ekuzuzeni ukuhlukaniswa kwendawo, isici esibalulekile sokuhlanganisa usimende we-wellbore.Zisebenza njengesithiyo phakathi kodaka lukasimende nolunye uketshezi oluphuma emthonjeni, ngaleyo ndlela luvimbele ukuxutshwa nokungcoliswa.Ipulaki engezansi, nesici sayo se-diaphragm, iqinisekisa ukuhlukana koketshezi kuze kube yilapho udaka lukasimende lufinyelela endaweni yalo ehlosiwe.Ngesikhathi esifanayo, ipulaki ephezulu inikeza inkomba ethembekile yokufika kwepulaki ngempumelelo kanye nokubekwa kukasimende ngokukhuphuka okubonakalayo komfutho wepompo.Ekugcineni, ukusetshenziswa kwalawa mapulaki kubangela ukusebenza kahle kukasimende okunokwethenjelwa, okubalulekile ekuzinzeni nasekuphileni isikhathi eside.
