Mhando Dzepfuti dzePerforating

Tubing Perforating Pfuti

Iyo thru tubing perforating pfuti inogona kumisa mamwe madhirigi nekupinda akawanda tambo dzekugadzira uye kuwana mamwe ekugadzira nzvimbo dzekugadzira pasina kubvisa tambo yekupedzisa kubva mutsime. Pamusoro pezvo, hapazove nechikonzero chekuwana workover kana drilling rig kuti tiite basa rakadaro sezvo isu tichigona kuboora rigless.

Zvakanakira

● Kudzora zvakanaka kwematsime kunogona kuwanikwa nekuda kwekurongedza uye tubing iri panzvimbo panguva yekuboora.

● Inobvumira kusaenzana kwakaderera pakuumbwa.

● Packer uye kupedza / DST zvishandiso zviri mutsime panguva perforating.

● Kusagadzikana kunobatsira pakucheneswa kwepaburi.

Zvakaipa

● Pfuti dzine madhayamita madiki ekunze uye machaji madiki achange aine mabhonzo mashoma.

● Pane kudikanwa kwekuisa pfuti munzvimbo dzakakwirira kuti zviite zvakanaka.

Underbalance kugumira kusvika ku1000 psi.

● Kuganhurirwa kwehurefu hweperforator nehupamhi hwekuzora, chigadziriso chekumisa, zviyereso zvakawedzerwa kurwisa kudzvanywa kwepamusoro, uye collar locator.

Types

Iko kune kunyanya matatu makuru marudzi e thru tubing perforating pfuti:

● Pfuti dzinoshandisa zvinhu zvinotakurwa zvakakwana.

● Avo vanoshandisa mari inodzoserwa yekutakura tambo yekutsigira iri muzviitiko zvinodhura.

● Pfuti umo muripo wechaji nemakepisi zvinoputsika kuita zvidimbu zvidiki mushure mekuputika

Retrievable Hollow Carrier Pfuti

Aya ndiwo madiki mavhezheni epfuti dzekukandira dzatinogona kumhanya netubing, nekudaro kuve ne180 yakaderera charge saizi uye, nekudaro, kuita zvirinani kupfuura dzimwe pfuti dzese. Vanongopa 0 o phasing ine max. ye4spf pa2 1/8 ”OD pfuti uye 6spf pa2 7/8” OD pfuti. Nekuda kwekumira-kure kubva kune casing iyo pfuti idzi dzingave nazvo, pachave nekudikanwa kwekumisikidza kana kuendesa maturusi.

Pfuti dzekutakura dzinowanikwa muhukuru hwakasiyana kubva pa30 mm (1 3/16 ″) kusvika 73 mm (2 7/8 ″) ye thru tubing application. Iyo shoma yekupedzisa tambo (Marudzi ekupedzisa) ID inoganhura saizi yakakodzera yepfuti. Nekudaro, pfuti diki dzinosvika 54 mm (2 1/8 ″) dzine simba shoma nekuda kwehukuru hwemuviri. Izvi zvinodzikamisa kureba kwechaji cheji.

Nokudaro, kureba kwejeti kunoderedza kuwanda kwezvinoputika pakuchaji imwe neimwe. Kunyanya kupfurwa nepfuti idzi pfuti gumi nemapfumbamwe pamita (6 kupfura netsoka). Isu tinokwanisa kumisikidza iyo thru tubing pfuti kuti ipe chero chero perforating phasing. Kusapinda zvakanaka kwezvidiki mhosva dzakapfurwa patsime zvinogona kukanganisa kudzikiswa kweganda rejometri nekuda kwekufamba.

Nheyo Yebasa

Pfuti dzinowanzo shandiswa ne zero phasing. Mukuwedzera, isu tinokwanisa kuisa pfuti nemagetsi kana magineti kuti tideredze mukaha pakati pepfuti uye pombi yekuisa. Idzo hombe 73 mm (2 7/8 ″) pfuti dzinopa mashandiro akafanana neakawanikwa nepfuti diki dzinoshandiswa kana semi-expendable capsule. Kuita kwavo kwekupinda kunobvumira kushandiswa kwavo muchikamu kana 360 ° spiral configuration, kuderedza geometrical ganda uye kunatsiridza inflow performance kunyangwe ikapfurwa mhiri kwechibhorani. Hollow carrier pfuti inoderedza kukuvadzwa kwecasing sezvo mutakuri ane simba rekuputika uye zvidimbu zvepamusoro zvemakesi ekuchaja akaumbwa.

Pfuti dzekutakura dzine maburi dzinoshanda kupfuura capsule pfuti mukupwanya nguva refu panguva yekumhanya kwega kwega. Izvi zvinodaro nekuti huremu hwemutakuri hunoderedza kudiwa kwemamwe uremu. Nekudaro, zvipingamupinyi zvemidziyo yekumanikidza yepamusoro zvinomisa kureba kwepfuti panguva imwe kusvika kumamita gumi.

Inodhura uye Semi-Inodhura Thru Tubing Perforating Pfuti

Pfuti dzinodhura uye dzinodhura dzinowanikwa kubva kumakambani mazhinji ebasa anopisa pasi pemazita akasiyana siyana ekutengesa uye anosiyana muhukuru kubva pa43 mm (1 11/16 ″) kusvika 73 mm (2 7/8 ″). Kuita kwavo kunowanzo kurira kune hollow carrier pfuti dzehukuru hwakafanana. Pfuti idzi dzinosanganisira machaji akaumbwa nemunhu, imwe neimwe iri mumudziyo wakasiyana wekumanikidza unotsigirwa newaya kana tambo dzekutakura.

Pfuti painorira mutsime, inopwanya midziyo yokumanikidza, inogona kugadzirwa nesimbi, aruminiyamu, kana kuti simbi. Pfuti dzinodhura dzinokwanisa kudzoreredza waya dzinotsigira kana mitsetse, asi pfuti dzekapsule dzinoshandiswa dzinodziparadza dzodzisiya mutsime. Iyo yakakwira-density tsvina inofanira kuwira pasi pegomba, asi yekutanga kuyerera kuyerera kunogona kuitakura. Mumatsime akatsemuka zvakanyanya, kukweshana kunogona kudzivirira marara kuti asadzika mugomba, zvichiita kuti simbi kana zvimwe zvinhu zvakatsemuka zvitakurwe kuenda pamusoro panogadzirwa tsime.

Kuti udzivise kukuvadzwa kwekukachidzwa, mavharuvhu ekuchengetedza pasi-pasi, uye michina yekugadzira pamusoro, zvakakosha kutora matanho ekudzivirira marara. Kuyerera kunodzokera pamusoro kuchave ne-yakaderera-density polymer zvinhu uye zvimedu zvezvinhu kubva mumudziyo wekumanikidza uye yakaumbwa yekuchaja kesi. Zvimedu izvi zvinofambiswa nesimba rekuputika uye kukanganisa pane casing, zvichikonzera kukanganisa kukuru uye kukurumidza kuora. Kuti udzivise kukuvara kwakanyanya kwecasing, unofanirwa kudzikisira saizi ye thru tubing perforating pfuti kusvika 54 mm (2 1/8 ″).

Cons

Mhando dzepfuti dzinokwidziridzwa uye dzine hafu dzinoonekwa sedzine simba pakati pemarudzi ese. Nekudaro, mabhenefiti avanopa anofanirwa kutariswa maererano nenyaya dzinomuka nekuda kwehuwandu hwakawanda hwemarara mutsime, mukana wekukuvadzwa kwekesi kunokonzerwa nekuchaja kwakasimba, uye kusavapo kwekavharivha yekuvharira kuputika.

Pfuti inoputika yakagadzirwa uye inogadzirwa neVigor R&D timu inogadzirwa zvakanyatsoenderana neyakajairwa SYT5562-2016, uye inogonawo kugadzirwa zvinoenderana nezvinodiwa nevatengi, kana iwe uchifarira yedu perforating pfuti dzakatevedzana, ndapota usazeza taura nesu kuti uwane zvigadzirwa zvemhando yepamusoro uye rutsigiro rwehunyanzvi hwepamusoro.
