Umgaqo kunye nendlela yokusebenza ye-magnetic positioning perforation

Ngokweemfuno zesicwangciso sophuhliso, i-perforating kukusebenzisa i-oyile ekhethekileyo ye-perforator ukungena kudonga lwe-casing kunye nomqobo wesamente yesamente yomgangatho ojoliswe kuyo ukwenza umngxuma wokudibanisa phakathi kwendawo ekujoliswe kuyo kunye ne-casing wellbore.Ngoko ke, ukutyhoboza kuyinyathelo elibalulekileyo lophuhliso lwe-oilfield kunye neendlela ezibalulekileyo zokuvelisa ioli, igesi kunye namanzi.

1.umgaqo wokusebenza we-positioner magnetic

Kuyaziwa kumthetho we-electromagnetic induction ukuba xa umazibuthe okanye ikhoyili ikwintshukumo ehambelanayo, imagnethi

Intsimi ye-etic ejikeleze utshintsho lwekhoyili, intambo yamagnetic inqumla i-coil ijika kwaye ivelise amandla okunyanzeliswa kunye nokunyanzeliswa kwangoku, i-coil ayikho i-loop, akukho yangoku i-induced, kuphela amandla abangelwayo akhoyo.Imeko esisiseko ye-electromagnetic induction yi-coil magnetic wire-cut ye-coil magnetic field ejikeleze ikhoyili, kunye nokwenza i-coil ye-magnetic cut-cut coil, i-flux magnetic of the magnetic field ejikeleze ikhoyili kufuneka itshintshwe.Oko kukuthi, umazibuthe kunye nekhoyili ikwintshukumo ehambelanayo, kodwa ubume bendawo yemagnethi ayivumeli umazibuthe kunye nekhoyili ukuba ibe kwintshukumo ehambelanayo, emva koko i-magnetic flux ejikeleze ikhoyili ayiyi kutshintsha, kwaye ayiyi kuvelisa. amandla okungeniswa, ukuze sikwazi ukusebenzisa olunye uhlobo lotshintsho lwemagnethi, oko kukuthi, sithembele kutshintsho lwemathiriyeli ye-ferromagnetic yangaphandle.Amandla anyanzelwayo aveliswa yimathiriyeli yangaphandle ye-ferromagnetic echaphazela indawo yayo yamagnetic ibonisa utshintsho kwimekobume yangaphandle.Ngoko ke, xa i-locator magnetic glides ngekhola kwi-casing, ukuhanjiswa komgca wemagnethi utshintshile ngenxa yokutshintsha kobunzima bezinto zangaphandle ze-ferromagnetic - udonga lwe-casing, ukwenzela ukuba amandla okufakelwa iveliswe ngokusika ikhoyili.Xa imbonakalo yophawu lwemagnethi yomqondiso irekhodwa kwisixhobo somphezulu, kuya kuqinisekiswa ukuba indawo yemagnethi idlula ikhola kubunzulu obuthile equleni.Ngaloo ndlela, inokulungelelanisa kunye nobunzulu benxalenye yesixhobo somhlaba ukugqiba umsebenzi wokumisa i-perforation.

2.Thobela iinkqubo zokusebenza ze-perforating site

(1)Bulala kakuhle ngokweemfuno zeskimu soyilo.

(2) Lungisa izixhobo zequla kunye nofakeloizixhobo zokulungiselela ngokufanelekileyo ukuthintela ukuvuthuza.

(3) Ngaphambi kokugqobhoza, i-casing kufuneka idlulengokusebenzisa iqula ngokwemigaqo, ukuhlamba isanti iqula ukuya ezantsi eyenziweyo equleni.

(4) Uxinzelelo lwe-Casing kufuneka luvavanywe kwaye coigqitywe phambi kokuba kugqobhozwe iqula elitsha.

(5) Ubunzulu bokugqobhoza impazamo siholo ingabi ngaphezu kwe-0.1m.

(6) Ukuba imitha yokugqobhoza ingaphezulu kwe-3m,iqula lingagqitywa kuphela emva kokuba umtya wombhobho uhlanjiwe.

(7) Umthombo womgca kufuneka uvavanywe aemva kokugqobhoza, umthamo we-extrusion mkhulu kune-1m³, uxinzelelo lwe-extrusion lungaphantsi kwe-15MPa, kwaye ixesha lokukhupha alikho ngaphantsi kwe-5min.

(8) Ngexesha lenkqubo yokugqobhoza,kufuneka kubekho umntu okhethekileyo wokunyamekela i-wellhead, ukukhusela izinto eziwela phantsi, kwaye ubeke ingqalelo ukuba kukho umboniso weoli kunye negesi.Ukuba ukuphuphuma kufunyenwe, i-perforation kufuneka imiswe, umtya wombhobho kufuneka ubanjwe ngokukhawuleza, kwaye uxinzelelo lwekholamu yolwelo kufuneka lulungiswe ngaphambi kokubhoboza.

(9) Kwinkqubo ye-cannonball, ukubakukho ukuchasana, ungabi nzima, kufuneka ubeke phambili i-cannonball, kwaye uthathe amanyathelo ahambelanayo emva kokufunda imeko ephantsi komhlaba.

(10) Ngexesha lonke ukwakhiwainkqubo, iqela lomsebenzi kufuneka lisebenze ngokusondeleyo neqela lokugqobhoza ukuze liphumeze ngokukhuselekileyo, kwaye akukho ziqhushumbisi zivunyelweyo malunga nentloko yequla.

(11) Ukuqokelelwa kwedatha yokwenziwa:

① Phonononga ulwakhiwo lokugqobhoza caNONE

② Ukulinganisa ukuxinana kolwelo lokubulala;

③ Indlela yokugqobhoza zimbini zompupe

④ Ukwakheka okuvulekileyo, ixesha lokuphumla, inani le-holes, emissivity;

⑤ Yintoni eboniswa emva kokugqojozwa;

⑥ ixesha lokugqobhoza kunye nocwangco;

⑦ Ezinye iimeko ezikhethekileyo.
