Sei uchishandisa ma casing stabilizers?

Kuisa Pakati Pechifukidziro

Kushandisa ma "casing centralizers" inzira yakakosha yekuvandudza kunaka kwe simende.

Chinangwa chekusimbisa chine zvinhu zviviri: chekutanga, kuparadzanisa kutenderera kweropa kusina kugadzikana, kana dzimwe nguva dzakaomarara nekavha, nokudaro zvichipa dziviriro yekuramba uchiboorera zvakachengeteka uye zvakanaka; chechipiri, kuparadzanisa zvinobudirira nzvimbo dzakasiyana dzemafuta negasi, kudzivirira mafuta negasi kuti zvisafambe zvichienda pamusoro kana kuti zvifambe pakati pemaumbirwo, uye kupa mugero wekugadzira mafuta negasi.

Zvichienderana nechinangwa chekusimbisa, zvinodiwa pakuongorora kunaka kwekusimbisa zvinogona kusimbiswa. Hunhu hwakanaka hwekusimbisa hunoreva kuti chivharo chiri pakati pegomba remvura, uye simende yakakomberedza chivharo inoparadzanisa chivharo nemadziro egomba remvura uye inoparadzanisa maumbirwo akasiyana kubva kune mumwe nemumwe.

Zvisinei, matsime chaiwo akacherwa haana kumira zvakanaka uye ane mwero wakasiyana wekutsauka. Nekuda kwekutsauka kwemasero emvura, chivharo hachizove pakati pechivharo, zvichikonzera kureba kwakasiyana uye madhigirii ekusangana nemadziro emvura. Izvi zvinoita kuti pave nekupatsanurwa kwakasiyana pakati pechivharo nemadziro emvura. Kana nzvimbo yakavhurika yakakura, ivhu rekutanga rinobviswa nyore nyore netsvina yesimende; zvakasiyana, kana nzvimbo yakavhurika iri diki, nekuda kwekusakwanisa kuyerera zvakanyanya, slurry yesimende inonetsa kubvisa ivhu rekutanga, zvichiita kuti pave nechinhu chinowanzonzi slurry channeling yesimende. Kana nzira yavhurika yaitika, nzvimbo dzemafuta negasi hadzigone kuparadzaniswa zvinobudirira, uye mafuta negasi zvinofamba nepakati pasina simende sheath.

Kushandiswa kwe casing centralizers ndekwekuti casing irambe yakamira pakati pevhu panguva yekuisa simende. Kune matsime anotungamira kana akatsauka zvakanyanya, casing centralizers dzinonyanya kukosha. Pamusoro pekudzivirira zvinobudirira simende kuti isatsvedzerere, casing centralizers dzinoderedzawo njodzi yekunamira kwe differential casing. Nekuti centralizer inochengetedza casing iri pakati pevhu, casing haimire pamadziro e wellbore; kunyangwe panguva dzinopinda mvura, casing hainyanyi kunamira nekuda kwedhaka remadhaka rinoumbwa nekumanikidzwa kwakasiyana. Casing centralizers inoderedzawo kukotama kwe casing mu wellbore (kunyanya muzvikamu zvakakura), nokudaro ichideredza kupera kwe casing ne drill strings kana zvimwe zvishandiso zve downhole panguva ye drilling inotevera, nokudaro ichidzivirira casing. Nekuda kwerutsigiro rwunopiwa ne casing centralizers, casing string inogona kutamiswa zviri nyore panguva ye cementing operations.

Muchidimbu, kushandisa ma "casing centralizers" inzira iri nyore, inoshanda, uye inokosha yekuvandudza kunaka kwe simende.
