Cement Retainer Plug In Oiri & Gasi Well Guide

Inflatable sevhisi maturusi ave achishandiswa muindasitiri yemafuta uye gasi kweanopfuura makore makumi mashanu kuita akasiyana ekugadzirisa workovers. Inflatablezvakanaka packers,bhiriji plugs, uye simende retainer inoshandiswa mumakomba akazaruka, makomba ane makese, akaiswa casing liners, uye zvidzitiro zvegravel-pack mumatsime emafuta uye gasi, asi zvinofanirwa kushandiswa chete kana zvishandiso zvakajairika zvisina kukodzera. Cement Retainers inonyanya kushandiswaKugadzirisa simende mabasa. Aya madhiri ekuchengetedza akaiswa akachengeteka mune cherotype of casing.

Zvishandiso zvinoputika zvinonyanya kukosha mumakomba akazaruka ehukuru husina chokwadi. Kungofanana neyakajairwa packers (tarisa zvakarePermanent Packers) uye mabhiriji plugs, inflatable sevhisi zvishandiso zvinogona kumisikidzwa mune chero array (kureva,,retrievable packer, resettable packer, retrievable bridge plug, and simende retainer), zvichibvumira maoparesheni mamwe chete kuti aitwe semichina yakajairika.

Inflatable simende retainer Kubatanidza gungano re-flapper-valve rine bhiriji rinogara rinoputika rinogadzira simiti inochengetedza. Masimende anochengeta anowanzo shandiswa kudzvanya kugadzirwa kusingadiwe kana nzira dzegasi pakati pegomba rakavhurika uye casing. Bull plug yepasi inobviswa yotsiviwa neshear-out ball seat. Iyo lift sub (Drilling Subs) pamusoro inotsiviwa negungano revhavha.

Iyo inflatable simende retainer inobvumira simende kuti iiswe mumachaneli. Kana simenti yave panzvimbo, iyohydrostatic pressureinorerutswa nekudhonza kunze kwemuchengeti. Kamwe kunze kwekuchengetedza, valve inovhara uye haibvumiri kuwedzera kusvina.

Kutenderera Kusvina

Iyo inotenderera inosvina inowanzoitwa nesamende retainer pachinzvimbo kune packer. Kutenderera kunowanikwa nemvura kana asidhi semvura yekutanga. Nguva yacho inotenderedzwa nemvura yekugezesa kuti ive nechokwadi chekucheneswa, uye simende inotsvedza inozopombwa yobviswa.

Hapana kumanikidza kuvaka kunoitika panguva yebasa, kunze kwekuwedzera kunokonzerwa neiyo hydrostatic pressure yesamende column sezvainoyerera ichikwira annulus. Kana kuiswa kwapera, stinger kana packer inosunungurwa. Iyo yakawandisa simende inotenderera kunze kwepamusoro perforations inogona kudzoserwa kunze kana ichidikanwa.

Huwandu hwe slurry hunodiwa kuti upedze kutenderera kusvina hazvizivikanwe; saka, yakawanda slurry yakagadzirirwa. Nekuda kweizvozvo, pane mukana wakasimba wekuti imwe simende slurry inogona kupinda mucasing,chibooresa pombi, kana tubing kana annulus pamusoro pechidzitiro chekusvina panguva yebasa.

Simende iyi ikaiswa, pombi yekuboorera (kana kuti tubing) inogona kunamira mugomba. Naizvozvo, kuderedza njodzi iyi, simende inochengeta inofanira kumhanyiswa panzvimbo pepakiti. Zviri nyore kubvisa stinger musangano pane packer, nekuti iyo yekupedzisira ine shoma casing clearance. Iyo inochengetedza inofanirwa kuiswa padyo sezvinobvira kune yepamusoro perforations. Izvi zvinoderedza kuratidzwa kwepombi yekuchera kune simende slurry inogona kupinda mutsime kuburikidza nepamusoro peforations.

Cement Svina

Cement Retainer inoshandiswa zvakare musimende kusvinamabasa. Kushandiswa kwayo kunoonekwa seimwe yemhando dzeSqueeze-tool yekuisa matekiniki. Iyi nzira inogona kupatsanurwa kuita zvidimbu zviviri — nzira inodzoreredzwa yekusvina packer uye inodhirowa simende retainer. Chinangwa chikuru chekushandisa kusvina maturusi ndeyekuparadzanisa casing uye tsime musoro uchiisa yakakwira pressure downhole.

Cement retainers ndeye drillable packers ane valve inoshandiswa ne stinger pamagumo ebasa rekushanda (Fig.1). Cement retainers inoshandiswa kudzivirira kudzoka shure kana pasina simenti inopera mvura inotarisirwa kana kana yakakwirira yakashata yakasiyana-siyana inogona kukanganisa keke yesamende. Mune mamwe mamiriro ezvinhu, kushandisa packer kune njodzi nekuda kwekugona kutaurirana nepamusoro perforations. Paunenge uchiisa simende nzvimbo dzakawanda, simende inochengetedza inoparadzanisa yakaderera perforations uye inozotevera zone kudzvanya kunogona kuitwa pasina kumirira kuti slurry igadzike.

A drillable retainer inopa opareta kuvimba kwakawanda mukuseta mutakuri padhuze nekukwara. Imwe bhenefiti ndeyekuti diki vhoriyamu yemvura pazasi pepakiri inotamiswa kuburikidza neiyo perforations pamberi pesimende slurry.
