Cement Casing Rubber Plug for oilfield
Inkcazo:
Iplagi yerabha isetyenziselwa ukwahlula udaka lwesamente kolunye ulwelo, ukunciphisa ungcoliseko kunye nokugcina ukusebenza kodaka oluqikelelweyo. Iindidi ezimbini zeeplagi zesamente zidla ngokusetyenziswa xa kusenziwa isamente. Iplagi esezantsi iqaliswe phambi kodaka lwesamente ukunciphisa ukungcoliseka ngolwelo olungaphakathi kwi-casing phambi kokufakwa kwesamente. I-diaphragm kumzimba weplagi igqabhuka ukuvumela udaka lwesamente ukuba ludlule emva kokuba iplagi ifikelele kwikhola yokumisa.
Iplagi ephezulu inomzimba oqinileyo onika isibonakaliso esilungileyo sokuqhagamshelana nekhola yokumisa kunye neplagi ephantsi ngokunyuka kwempompo yoxinzelelo.
Iiplagi zokusamente ngamacandelo abalulekileyo ekuphumezeni ukwahlukaniswa kwendawo, umba obalulekileyo wokufakwa kwesamente kumthombo. Zisebenza njengomqobo phakathi kodaka lwesamente kunye nolunye ulwelo lwe-wellbore, ngaloo ndlela luthintela ukuxubana kunye nokungcoliseka. Iplagi engezantsi, kunye nesici sayo se-diaphragm, iqinisekisa ukuhlukana kwamanzi kuze kube yilapho i-sement slurry ifikelela kwindawo ekujoliswe kuyo. Kwangaxeshanye, iplagi ephezulu ibonelela ngesalathiso esithembekileyo sokufika kweplagi ngempumelelo kunye nokubekwa kwesamente ngokunyuka okubonakalayo koxinzelelo lwempompo. Ekugqibeleni, ukusetyenziswa kwezi plugs kukhokelela ekusebenzeni okusebenzayo kunye nokuthembekileyo kwesamente, okubalulekileyo kuzinzo kunye nokuphila ixesha elide.
