Iintlobo zeMipu yokuGqiba

Umpu oqhumayo wetyhubhu

I-thru tubing perforating guns ingenza i-reservoirs eyongezelelweyo isebenze ngokungena kwiintambo ezininzi zemveliso kunye nokufikelela kwiindawo ezongezelelweyo zemveliso ngaphandle kokususa umtya wokugqitywa kwiqula. Ukongeza, akusayi kubakho mfuneko yokufumana i-workover okanye i-drilling rig ukwenza umsebenzi onjalo njengoko sinokubhobhoza ngokungenasiphelo.

Iingenelo

● Ulawulo olungcono lomthombo lunokuphunyezwa ngenxa yokuba umpakishi kunye netyhubhu ikhona ngexesha lokugqobhoza.

● Ivumela ibhalansi elinganiselweyo kulwakhiwo.

● I-Packer kunye nokugqitywa / izixhobo ze-DST zisequleni ngexesha lokugqobhoza.

● Ukulungelelana kunceda ekucoceni imingxuma.

Iingxaki

● Imipu ene-diameter encinci yangaphandle kunye neentlawulo ezincinci ziya kuba nomsebenzi oqingqiweyo wokugqobhoza.

● Kukho imfuneko yokwahlula-hlula imipu ukuze kuphuculwe ukusebenza kakuhle.

Umda we-underbalance ukuya malunga ne-1000 psi.

● Ukucuthwa kobude be-perforator ngobude be-lubricator, isixhobo sokumisa, iintsimbi ezongeziweyo zokuchasana noxinzelelo oluphezulu, kunye ne-collar locator.

Iintlobo

Kukho ubukhulu becala ezintathu iindidi eziphambili ze-thru tubing perforating gun:

● Imipu esebenzisa izithwali ezinokubuyiswa ngokupheleleyo.

● Abo basebenzisa iintlawulo zenkxaso yecarrier stripeable equlethwe kwiimeko ezinokuthengiseka.

● Imipu apho ityala kunye neekepusi ziqhekeka zibe ziingceba ezincinci emva kokugqabhuka

Imipu yokuthwala eHollow enokufunyanwa

Ezi ziinguqulelo ezincinci zecasing gun esinokuthi siziqhube kwi-tubing, kungoko sinexabiso eliphantsi le-180 kwaye, ngenxa yoko, ukusebenza okungcono kunayo yonke eminye imipu. Banikezela kuphela ngo-0 o ngezigaba kunye nobuninzi. ye-4spf kwi-2 1/8 ” OD gun kunye ne-6spf kwi-2 7/8” OD umpu. Ngenxa yokuma kwi-casing enokuthi le mipu ibe nayo, kuya kubakho imfuneko yoqhelaniso okanye izixhobo zokwabela amagunya.

Imipu yokuthwala iHollow iyafumaneka ngokobukhulu obahlukeneyo ukusuka kwi-30 mm (1 3/16″) ukuya kwi-73 mm (2 7/8″) ngokusetyenziswa kwetyhubhu. Ubuncinane bomtya wokugqibezela (Iintlobo zokugqibezela) i-ID inciphisa ubungakanani bompu obufanelekileyo. Nangona kunjalo, imipu emincinci ukuya kuthi ga kwi-54 mm (2 1/8″) inamandla alinganiselweyo ngenxa yobukhulu bayo bomzimba. Oku kuthintela ubude belinen yokutshaja emile.

Ngenxa yoko, ubude bejethi bunciphisa inani leziqhushumbisi kwintlawulo nganye. Ubuninzi bokudutyulwa kwale mipu ziimbumbulu ezili-19 ngemitha nganye (6 ngonyawo ngalunye). Sinokuyiqwalasela imipu yetyhubhu ukunika phantse nasiphi na isigaba sokugqobhoza. Ukungenwa kakubi kweendleko ezincinci ezigxothwe kumthombo womthombo kunokwenzeka ukuba kunciphise ukucutheka kwesikhumba sejiyometri ngenxa yezigaba.

Umgaqo woMsebenzi

Imipu ngokuqhelekileyo isetyenziswa nge-zero phasing. Ukongezelela, sinokubeka isibhamu ngomatshini okanye ngombane ukuze sinciphise isithuba phakathi kompu kunye nombhobho we-casing. Imipu emikhulu eyi-73 mm (2 7/8″) inika ukusebenza ngokuthelekiswa naleyo ifunyenwe ngemipu emincinci enokuchithwa okanye efikeleleka lula. Ukusebenza kwabo kokungena kuvumela ukusetyenziswa kwabo kwisigaba okanye i-360 ° ukulungelelaniswa kwe-spiral, ukunciphisa ulusu lwejometri kunye nokuphucula ukusebenza kwe-inflow naxa kugxothwa kwi-borehole. Imipu yokuthwala iHollow inciphisa umonakalo wecasing njengoko umthwali ephethe amandla ogqabhuko-dubulo kunye namaqhekeza esantya esiphezulu samatyala entlawulo amile.

Imipu yokuthwala engenanto isebenza ngakumbi kunemipu ye-capsule ekugqobhozeni ixesha elide ngexesha lokubaleka ngalunye. Oku kungenxa yokuba ubunzima bomthwali bunciphisa isidingo sobunzima obongezelelweyo. Nangona kunjalo, imiqobo yezixhobo zoxinzelelo lomphezulu inciphisa ubude bompu ngexesha elinye ukuya malunga neemitha ezili-10.

Ixabisa kakhulu kwaye iSemi-Ixabisa kakhulu imipu yokuGxiba ngeTubing

Imipu efikelelekayo kunye nexabiso eliphantsi iyafumaneka kwiinkampani ezininzi zenkonzo yokugqobhoza phantsi kwamagama ahlukeneyo orhwebo kunye nobukhulu ukusuka kwi-43 mm (1 11/16″) ukuya kwi-73 mm (2 7/8″). Ukusebenza kwabo ngokuqhelekileyo kuphezulu kunemipu engenanto efana nesayizi. Le mipu iquka iintlawulo ezimile okwezomntu ngamnye, nganye ikwinqanawa yoxinzelelo eyahlukileyo exhaswa ngamacingo okanye imicu yokuthwala.

Xa umpu udubula equleni, uqhekeza iinqanawa zoxinzelelo, ezinokwenziwa ngeceramic, ialuminiyam okanye intsimbi, zibe ngamaqhekeza amancinci. Imipu enexabiso eliphantsi inokuphinda ibuyise iingcingo ezixhasayo okanye imicu, kodwa imipu ye-capsule esetyenziswayo iyayitshabalalisa kwaye iyishiye equleni. Inkunkuma enoxinano oluphezulu kufuneka iwele ezantsi equleni, kodwa ukuqukuqela kokuqukuqela kokuqala kunokuwuthwala. Kwimingxuma etenxe kakhulu, ukukhuhlana kunokuthintela ubutyobo ukuba bungehli equleni, nto leyo ebangela ukuba intsimbi okanye ezinye izinto eziqhekezayo zithwalwe phezulu xa iqula lisenziwa.

Ukuthintela umonakalo wokukrwitshwa, iivalvu zokhuseleko ezingaphantsi komhlaba, kunye nezixhobo zokuvelisa umphezulu, kubalulekile ukuthatha amanyathelo okuthintela ubumdaka. Ukuqukuqela okubuyela kumphezulu kuya kuqulatha izinto eziphantsi koxinaniso lwepolymer kunye neziqwenga zezinto ezivela kwinqanawa yoxinzelelo kunye netyala lentlawulo elimile. Ezi ziqwenga ziqhutywa ngamandla okuqhuma kunye nefuthe kwi-casing, ebangela umonakalo omkhulu kunye nokukhawuleza ukubola. Ukuthintela umonakalo ogqithisileyo we-casing, kufuneka unciphise ubungakanani be-thru tubing perforating guns ukuya kwi-54 mm (2 1/8").

Ububi

Iindidi ezinokwandiswa kunye ne-semi-exparable zemipu zithathwa njengezona zinamandla kuzo zonke iintlobo. Nangona kunjalo, izibonelelo abazinikezelayo kufuneka ziqwalaselwe ngokuchasene nemiba evelayo ngenxa yezixa ezibalulekileyo zobutyobo kumthombo, ukuba nokwenzeka komonakalo wecasing obangelwe ziintlawulo ezinamandla ngakumbi, kunye nokungabikho kwendawo ebiyelweyo yokuvala ugqabhuko-dubulo.

Umpu we-perforating owenziwe kwaye uveliswa liqela le-Vigor R&D iveliswa ngokungqongqo ngokuhambelana nomgangatho we-SYT5562-2016, kwaye unokwenziwa ngokwezifiso ngokweemfuno zabathengi, ukuba unomdla kuthotho lwethu lwemipu ebhobhozayo, nceda unganqikazi qhagamshelana nathi ukuze ufumane iimveliso ezisemgangathweni kunye nenkxaso yobugcisa.
