Basa re sleeve stabilizer

Kushandiswa kwesleeve stabilizers chiyero chakakosha chekuvandudza kunaka kwesamende. Chinangwa chekuisa simende chakapetwa kaviri: chekutanga, kushandisa casing kuvhara mativi emutsime anogona kudonha, kubuda, kana mamwe mamiriro akaomarara, zvichipa vimbiso yekuchera yakachengeteka uye yakatsetseka. Chechipiri ndechekunyatsoparadzanisa madhirigi eoiri negasi akasiyana, kudzivirira mafuta negasi kuyerera kusvika pamusoro kana kubuda pakati pemaumbirwo, zvichipa nzira dzekugadzira mafuta negesi.

Zvinoenderana nechinangwa chekuisa simende, zviyero zvekuongorora simende mhando inogona kutorwa. Iyo inonzi yakanaka simende yemhando inonyanya kureva casing iri pakati petsime, uye sheadhi yesimende yakatenderedza casing inonyatso kupatsanura casing kubva kumadziro etsime uye kuumbwa kubva pakuumbwa. Zvakadaro, tsime chairo rakacherwa harina kumira mushe uye rinogona kuguma nemadhigirii akasiyana ekurerekera kwetsime. Nekuda kwehuvepo hwetsime remvura, iyo casing haizogara mukati memutsime, zvichikonzera kureba uye madhigirii ekusangana nemadziro etsime. Mukaha pakati pekasi uye chitubu chinosiyana muhukuru, uye kana simende slurry inopfuura munzvimbo dzine mapeji makuru, iyo yekutanga slurry inotsiviwa nyore; Pane zvinopesana, kune avo vane mapeji maduku, nekuda kwekudzivirira kwepamusoro-kuyerera, zvakaoma kuti simiti slurry itsive dhaka rekutanga, zvichiita kuti chiitiko chinozivikanwa chinowanzozivikanwa che simenti slurry channeling. Mushure mekugadzirwa kwechanneling, mafuta uye gasi reservoir haigoni kuiswa chisimbiso zvakanaka, uye mafuta uye gasi zvichayerera munzvimbo dzisina simende zvindori.

Kushandisa sleeve stabilizer kuisa pakati casing zvakanyanya sezvinobvira panguva yekuisa simende. Kuti usimbise matsime anonanga kana akatsauka zvakanyanya, zvinotonyanya kukosha kushandisa sleeve stabilizers. Iko kushandiswa kwecasing centralizers hakungogone kudzivirira simende slurry kubva pakupinda mugroove, asi zvakare kuderedza njodzi yekuisa kumanikidza musiyano uye kunamatira. Nekuti iyo inodzikamisa inoisa iyo casing, iyo casing haizonyatso kusungirirwa kumadziro etsime. Kunyangwe muzvikamu zvematsime zvine kupenya kwakanaka, iyo casing kashoma kuti inonamirwa nemadhaka makeke anoumbwa nekudzvanyirira kusiyanisa uye kukonzera kudhirowa jamu. Sleeve stabilizer inogonawo kuderedza kupeta dhigirii yekasi mukati megomba (kunyanya muchikamu chikuru chetsime), izvo zvinoderedza kupera kwechigadzirwa chekuchera kana mamwe maturusi ekudzikisa pane casing panguva yekuchera mushure mekunge casing yaiswa, uye kuita basa rekuchengetedza casing. Pamusana pekutsigirwa kwesleeve stabilizer pane casing, nzvimbo yekubatana pakati pekasi uye tsime inoderedzwa, iyo inoderedza kupesana pakati pekasi uye tsime. Izvi zvinobatsira kuti casing idzikiswe mutsime uye kuti casing ifambiswe panguva yekuisa simende.
