Isebenza kanjani i-TCP

I-Tubing Conveyed Perforating (TCP) Bottom Hole Assemblies (BHA) ngokuvamile iqukethe ikhanda elidubulayo, isiqalisi se-percussion, izibhamu ezibhobozayo, iziqhumane ezibambezelekayo zesikhathi phakathi kwezibhamu, isiqalisi sethuluzi lokusetha, nepulaki. Umqalisi, owaziwa nangokuthi i-CP Detonator, usetshenziselwa ukuqalisa ngokuthembekile i-BHA yemigodi engaphansi ukuze iqhume embonini kawoyela negesi.
Amandla omthelela wemishini avela ekhanda elidubulayo aguqulwa abe okukhiphayo okuqhunyiswa ngumqalisi odingekayo ukuze kuqhunyiswe isibhamu sokuqala ku-BHA. Imishini yokudlulisa imishini isetshenziswa phakathi kwezibhamu ezibhobozayo ukuze kuqalwe iziqhumane noma iziqhumiso zeziqhumiso ezibambezeleke isikhathi ukuze zinikeze isikhathi esinokwethenjelwa sokudonsela kuqoqo elilandelayo lokubhoboza. Amadivayisi okudlulisa aqhumayo angasetshenziswa futhi ukujoyina izindlela ezingasasebenzi noma eziyimpinda ezitimeleni zokuqalisa ezingasasebenzi. Izikhathi zokulibaziseka ezinembile zifinyelelwa phakathi kwemizuzu engu-5 nengu-6 emgodini ophansi futhi zincike Kumazinga Okushisa Embobo Ephansi (BHT). Ukuze kwenziwe imisebenzi esebenza kahle kakhulu, iziqhumisi zokulibaziseka ezingaphezu kwezikhathi ezingamashumi amathathu (30) zisetshenziswe ngokuthembekile ekugijimeni okukodwa phakathi kwezibhamu ezibhobozayo. Ngokusebenza kwepulaki ne-perf, amandla omthelela wemishini avela ekhanda elidubulayo, noma idivayisi yokudlulisa, asebenzisa isiqalisi se-rapid deflagrating material (RDM) esisetshenziselwa ukokhela ngokuthembekile ama-propellants ekusetheni amathuluzi okuqinisekisa izilinganiso zokusha ezingaguquki ngaphambi kokuhlukaniswa kwepulaki.

Izinzuzo ze-TCP

Ukusebenza Ngempumelelo. I-TCP ivumela opharetha womthombo ukuthi abhoboze izikhawu ezinde, noma ezihlukaniswe kabanzi, ngesikhathi esisodwa ohambweni olulodwa lokungena emthonjeni kunokuba enze imigijimo eminingi ngocingo. Umehluko phakathi kwe-TCP nesikhathi se-wire-perforating rig sincike kubude besikhawu kanye nenani lokwehla kocingo uma kuqhathaniswa nesikhathi esengeziwe sokumisa intambo nokulungiselela umthombo wokusebenza kwe-TCP. Kodwa-ke, i-TCP iveza isibhamu endaweni yomthombo isikhathi eside kunokubhoboza izintambo, okukhathazayo ekusebenzeni okunezinga lokushisa eliphezulu. I-TCP ivumela opharetha womthombo ukuthi enze ukuhlolwa kokugeleza ngokushesha ngemva kokubhoboza. Amasu okuhlola ohlobo lwe-impulse angakwazi ukukhomba izinga lomonakalo we-wellbore ngaphambi kokuthi kwenziwe ukutshalwa kwezimali okukhulu kokuvuselela noma ukupakisha amatshe. Ngaphezu kokuhlola umfutho, izinhlobonhlobo zezinye izisetshenziswa zokuhlola nokuqedela zingahlanganiswa neyunithi yezinhlamvu ze-TCP ukuze kuhlinzekwe ukuhlolwa okuphelele kwechibi ngokushesha ngemva kokubhoboza.

Ngaphansi kwe-Perforating elinganiselwe. Ukungalingani, okusungulwe phakathi kokwakhiwa kanye nezingcindezi zemithombo yamanzi ngaphambi kokuba kuqhunyiswe izibhamu ze-TCP, kudala ukugeleza koketshezi okwakheka khona ngokushesha nokulawulwayo emthonjeni, okuhlanza ukubhoboza futhi kuthuthukise ukukhiqiza komthombo kanye nokujova.

Ukuphepha.

Imishini yokulawula kahle ebusweni iyafakwa futhi ihlolwe ngaphambi kokubhobozwa, okuqinisekisa ukuphepha okuphelele kuzo zonke izigaba zokusebenza kwe-TCP. Izigaba zokusebenza kwe-TCP. Amasistimu Okusebenza Asezingeni Eliphezulu. Usayizi wesibhamu unqunyelwe i-ID yekesi, evumela ukusetshenziswa kwezindleko ezinkulu kakhulu ezivumela ukusetshenziswa kwezindleko ezinkulu kakhulu (okungaba ukungena okujulile noma uhlobo lwembobo enkulu) kanye nokuminyana kwesibhamu esiphezulu. Izibhamu zingahlelwa kabusha ukuze zinikeze ukuminyana kwesibhamu esiphezulu kanye nephethini yohlelo oluthile.

Izinhlobo Zokuqedwa kwe-TCP

Ukuqedwa Kwesikhashana Kwe-TCP. Ekuqedweni kwe-TCP yesikhashana, izibhamu zifakwa emthonjeni ekupheleni kwentambo yomsebenzi. Ngemva kokudutshulwa kwezibhamu, futhi isikhathi sivunyelwe sokuhlanza nokuhlolwa, umthombo ubulawa ngoketshezi oluphelele olungalimazi bese kukhishwa intambo ye-TCP. Izinqubo zokuqedela-ukugeza i-backwashing, ukufaka i-asidi, izinqubo-ukugeza i-backwashing, ukufaka i-asidi, ukuqhekeka, noma ukupakishwa kwegravel bese kwenziwa. Izikhawu Ezinkulu noma Imithombo ye-Multizone. Izikhawu ezinkulu noma imithombo lapho izindawo eziningi ezinezikhala ezibanzi zihlanganiswa zibe iyunithi yezinhlamvu eyodwa yokukhiqiza ziqedwa ngokuphumelelayo ekusebenzeni kwesikhashana. Ngemva kokubhoboza, umthombo ubulawa ngokubhoboza okungalimazi, umthombo ubulawa ngoketshezi oluphelele olungonakali futhi intambo yesibhamu iyakhishwa. Lolu hlelo lunikeza izinzuzo ze-TCP kuyilapho lunikeza enye indlela yokushiya intambo yesibhamu emthonjeni lapho ingase iphazamise ukusebenza kwesikhathi esizayo. Imithombo Egcwele Amatshe. Izibhamu ze-TCP ezinohlonze ophakeme kakhulu ezilayishwe ngamashaji amakhulu okungena ezimbotsheni ezidutshulwe ngaphansi kokulinganisa zisetshenziselwa ukubhoboza indawo ukuze kugcwaliswe amatshe. Ngemva zone perforated ukuba amatshe amatshe-packed. Ngemva kokuhlanza, umthombo ubulawa ngoketshezi olungalimazi futhi izibhamu ziyalandwa ukuze kuvunyelwe ukusebenza kwezikrini nokufakwa kwephakethe legravel. Ukuhlola. I-valve elawula kahle ingasetshenziswa ngokuhambisana ne-TCP ukuze kuhlinzekwe ukubukeka okusheshayo endaweni eseduze nomthombo ngokuhlolwa okungazelelwe. Ukuhlolwa kwesiqu sesikhathi eside (i-DST) kunikeza ukuhlaziya okuningiliziwe kwamandla okuhweba echibi ngokubheka izinhlobo zoketshezi ezitholiwe kanye namazinga okugeleza. Inhlanganisela ye-DST/TCP iqinisekisa ukuhlanzwa kwe-perforation okuphelele futhi inikeza izici zokusebenza kwechibi. Uhlelo lubandakanya izibhamu ze-TCP ezisebenza ngaphansi kwesipakishi esingabuyiswa kanye nesethi yamathuluzi e-DST. Ngokushesha ngemva kokudubula, umthombo wahlolwa ngokugeleza ngokushintshana nokuvaleka ukuze kuthuthukiswe ulwazi olufiselekayo lwedamu.

Ukuqedwa Kwe-TCP Engunaphakade. Ekuqedeni Okungapheli kwe-TCP. Ekuqedeni unomphela, izibhamu ziqhutshwa ukuqedwa kwe-TCP unomphela, izibhamu ziqhutshwa ekupheleni kochungechunge lokugcina lokuphothula. I-wellhead nemishini yokuphepha ifakwa ngaphambi kokudubula. Izibhamu zihlala emthonjeni ngemva kokuhlinzwa futhi zingase ziphonswe ku-rathole uma zifunwa.

Njengomkhiqizi ochwepheshile wokubhoboza izibhamu, izibhamu zethu ezibhobozayo zingaqinisekisa ikhwalithi enhle kakhulu, futhi onjiniyela bethu bezobuchwepheshe bangakwazi nokwenza ukuhlela okunengqondo kwephrojekthi ngokwezidingo zakho ukuze bakusize wonge izindleko futhi unciphise izingozi. Uma unentshisekelo ngezibhamu ze-Vigor's TCP noma ze-WCP, sicela ungangabazi ukusithinta ukuze uthole amathuluzi wokuqedela wekhwalithi engcono kakhulu kanye nezinsizakalo zokuthenga ezisezingeni eliphezulu.
