Gucunga Isima Gucomeka mumavuta na gazi neza

Ibikoresho bya inflatable byakoreshejwe munganda za peteroli na gaze mumyaka irenga 50 kugirango bakore imirimo itandukanye yo gukosora. Inflatableabapakira neza,ibiraro, na sima igumana ikoreshwa mubyobo bifunguye, ibyobo bifunze, byerekanwe Ikariso, hamwe na kaburimbo-yamashanyarazi mu mariba ya peteroli na gaze, ariko bigomba gukoreshwa gusa mugihe ibikoresho bisanzwe bidakwiriye. Kugumana sima bikoreshwa cyane cyaneIbikorwa byo gutunganya sima. Aba bagumya gucukura bashizwe mumutekano muri buriweseUbwoko bwa Case.

Ibikoresho bitwikwa ni ingirakamaro cyane cyane mu mwobo ufunguye ubunini butazwi. Nkabapakira bisanzwe (reba kandiAbapakira burundu) n'amacomeka yikiraro, ibikoresho bya serivisi byaka birashobora gushirwaho muburyo ubwo aribwo bwose (urugero,gupakira, gusubiranamo gupakira, gucomeka ikiraro gishobora kugarurwa, hamwe na sima igumana), kwemerera ibikorwa bimwe gukorwa nkibikoresho bisanzwe.

Ububiko bwa sima bugurumana Guhuza inteko ya flapper-valve hamwe nikiraro gihoraho cyaka umuriro bigumana sima. Ububiko bwa sima busanzwe bukoreshwa muguhagarika umusaruro udashaka cyangwa imiyoboro ya gaze hagati yumwobo ufunguye. Amapfizi yo hepfo yamashanyarazi akurwaho agasimbuzwa intebe yumupira. Kuzamura sub (Gucukura) hejuru isimbuzwa inteko ya valve.

Igikoresho cya sima kigurumana cyemerera sima gushirwa mumiyoboro. Isima imaze kuba, iumuvuduko wa hydrostatikeyorohewe no gukuramo uwagumanye. Iyo umaze gusohoka muri reta, valve irafunga kandi ntabwo yemerera gukomeza kunyunyuza.

Kuzenguruka

Kuzenguruka kuzenguruka akenshi bikorwa hamwe na sima igumana guhitamo abapakira. Kuzenguruka bigerwaho n'amazi cyangwa aside nk'amazi abanza. Intera izengurutswe n'amazi yo gukaraba kugirango isukure neza, hanyuma isima ya sima ihita ivomwa ikimurwa.

Nta kwiyongera k'umuvuduko bibaho mugihe cyakazi, usibye kwiyongera guterwa numuvuduko wa hydrostatike winkingi ya sima nkuko itemba annulus. Iyo ibibanza bimaze kurangira, stinger cyangwa abapakira bararekuwe. Isima irenze izenguruka hanze yo hejuru irashobora guhindurwa iyo ubishaka.

Ingano ya slurry isabwa kugirango irangize kuzenguruka ntizwi; kubwibyo, harateguwe byinshi. Kubwibyo, haribishoboka cyane ko bimwe mubisima bya sima bishobora kwinjira mukibanza,umuyoboro, cyangwa tubing cyangwa annulus hejuru igikoresho cyo gukanda mugihe cyakazi.

Niba iyi sima ishyizweho, umuyoboro wa dring (cyangwa tubing) urashobora guhagarara mumwobo. Kubwibyo, kugirango ugabanye ibi byago, kugumana sima bigomba gukoreshwa aho kubipakira. Biroroshye kuvanaho inteko ya stinger kuruta abapakira, kuberako iyanyuma ifite case yoroheje. Kugumana bigomba gushyirwaho hafi hashoboka kuri perforasi yo hejuru. Ibi bigabanya kwerekana imiyoboro ya drillage kumasima ya sima ishobora kwinjira mumariba unyuze hejuru.

Gufata sima

Kugumana sima ikoreshwa nayo murisimaakazi. Imikoreshereze yacyo ifatwa nkubwoko bwa tekinike yo gushyira ibikoresho. Ubu buhanga bushobora kugabanywamo ibice bibiri - uburyo bwo kugarura ibintu bushobora kugarurwa hamwe nuburyo bwo kugumana sima. Intego nyamukuru yo gukoresha ibikoresho byo gukanda ni ugutandukanya agasanduku n'iriba mugihe ukoresha umuvuduko ukabije.

Abagumana sima ni abapakira bapakurura bafite valve ikoreshwa na stinger kumpera yakazi (Ishusho.1). Kugumana sima bikoreshwa mukurinda gusubira inyuma mugihe nta sima ihari iteganijwe cyangwa mugihe umuvuduko mwinshi utandukanye ushobora guhungabanya cake ya sima. Mubihe bimwe, gukoresha paki birashobora guteza akaga kuberako itumanaho rishobora gutoboka hejuru. Iyo gushimangira uturere twinshi, kugumana sima itandukanya perforasi yo hepfo hanyuma gukanda kwa zone birashobora gukorwa udategereje ko ibishishwa bishyirwaho.

Kugumya kugumya guha umukoresha ikizere cyinshi mugushiraho abapakira hafi ya perforasi. Iyindi nyungu nuko ingano ntoya ya fluid iri munsi yabapakiye yimurwa binyuze muri perforasi mbere ya sima.

Ikipe ya Vigor izashyira ahagaragara ibicuruzwa byacu bishya WID RANGE BRIDGE PLUG mugihe cya vuba, niba ushaka kumenya byinshi kuri yo, nyamuneka ntutindiganye kutwandikira kugirango ubone inkunga ya tekiniki yumwuga hamwe ninkunga yibicuruzwa.

Kubindi bisobanuro, urashobora kwandika kuri agasanduku k'ipositainfo@vigorpetroleum.com&kwamamaza@vigordrilling.com
