3.Ibikoresho byo gupakira bya RTTS biroroshye gukoresha, bihendutse, bishobora kugabanya cyane ikiguzi, kandi bikagira inyungu nziza mu bukungu no mu mibereho myiza.

Udupaki twa RTTS (Retrievable Test-Treat-Squeeze) ni udupaki tworoshye kandi dushobora gukuramo dukoreshwa mu gupima, kuvura no gusimbuza. Kenshi na kenshi, iki gikoresho gikoreshwa mu mwobo urimo icyuma gifunga J, ibyuma bifunga, ikintu gifunga, n'icyuma gifunga hydraulic. Udupaki tunini kandi dukomeye mu buryo bwo gufunga hydraulic dufasha gukumira ko igikoresho kijya mu mwobo. Ku dupaki two gufunga ≤ santimetero 88.9 (88.9 mm), isoko yo gukurura ikoresha uburyo bwa J, mu gihe ku dupaki two gufunga ≥ santimetero 101.6 (101.6 mm), hakoreshwa agace ko gukurura. Udupaki twose tuza dufite agasanduku ka J. Iyo hakoreshejwe valve ifunga, iba ifunze, ishobora gukoreshwa nk'icyuma gifunga na valve ifunga. Iyo valve ishyizwe, valve ifunga ubwayo mu mwanya wayo. Mu gihe cyo gupima cyangwa gushyira sima, igikoresho gifunga kibuza valve gufunguka. Agace ka J gagororotse mu mwanya wo gufungura gahuye n'agace ka J gagororotse (ni ngombwa) mu gice cyo gupakira. Uku guhuza bikuraho gukenera kuzunguruka umuyoboro kugira ngo ufunge valve izenguruka cyangwa kongera gushyiramo umuyoboro nyuma yuko umuyoboro uvanyweho na sima.

Ibiranga:

1. Imiterere y’agace k’umuyoboro w’imashini gapfundikiramo ibintu (packer mandrel bor) ituma amazi menshi anyura muri icyo gikoresho. Imbunda zitobora zirimo imiyoboro n’ibindi bikoresho by’insinga bishobora kunyura muri icyo gikoresho.
2. Agapaki gashobora gushyirwaho no guhindurwa inshuro nyinshi binyuze mu gukoresha imiyoboro y'amazi mu buryo bworoshye.
3. Utwuma twa tungsten carbide dutanga imbaraga zo gufata no kudashira neza, ibyo bikaba ingirakamaro cyane cyane iyo dukoreshejwe mu gasanduku gakomeye. Igitutu gishyirwa mu muyoboro gikoresha utwuma dushyirwa mu buryo bwo gufunga hydraulic.

4. Valve isanzwe izunguruka ifunguye cyangwa ifunze mu gihe cyo gupima ibintu, kandi ifungurwa byoroshye iyo bikenewe kugira ngo igere hejuru y'agapaki.

Imikorere:

Kugira ngo ushyireho agapaki, igikoresho gishyirwa munsi gato y’aho gishyirwa hanyuma kikazamurwa kikazunguruka inshuro nyinshi. Iyo igikoresho kiri hasi, bishobora kuba ngombwa kugizunguruka igice cy’izunguruka. Ariko, mu byobo byimbitse cyangwa byacitse, hashobora kuba ngombwa kuzunguruka inshuro nyinshi hakoreshejwe igikoresho gizunguruka. Kugira ngo ukomeze aho uhagaze, imbaraga zo gukoresha iburyo zigomba gukomeza kugeza igihe ibikoresho bishyirwa ku gikoresho bishyizwe kandi bigatangira gutwarwa n’uburemere. Igitutu kiringaniye kigomba gushyirwa ku mpande zombi z’agapaki kugira ngo upakire agapaki. Iyo ukuye mu muyoboro, valve izenguruka ikomeza gufungwa, bigatuma habaho uruziga rw’amazi inyuma hepfo y’agapaki. Iyo umuyoboro umanuwe, ukazunguruka iburyo, hanyuma ukazamuka, valve izenguruka irakinguka kugira ngo amazi asohoke mu mwobo.

Uburyo bwo gushyiraho no gusohora RTTS Packer

Mbere yo gukoresha umwobo wo hasi wa packer, shyiramo agakoresho ko gukurura hejuru no hasi inshuro nyinshi kugira ngo urebe ko imiyoboro y'amashanyarazi igenda, hanyuma uyinjize mu mwobo.

Mu gihe witegura kwinjira mu mwobo, funga valve izenguruka mu mwanya ufunguye; umwanya wa J nawo uri mu mwanya ufunze, ni ukuvuga agace kari ku gice cyo gufunga cya J, kandi agace ko gupfunyika kari mu mwanya wo gusubira inyuma.

Mu gihe cyo gukora, uburyo bwo kunyerera buzamuka, bushyiraho uburyo bwo kunyerera bugafunga valve izenguruka. Kugira ngo wirinde ko valve ifungwa ku buryo butunguranye, gabanya umugozi w'umuyoboro hanyuma uwuzunguruke iburyo, uwuzamure ugere aho ufunguye, hanyuma uwuzunguruke ibumoso ugere aho ufunguye, witondere kudakuraho umugozi w'umuyoboro.
Iyo igikoresho kigeze aho igikorwa kigomba gukorerwa, gimanure gato munsi y'aho gishyirwa, hanyuma ukizamure ugishyire aho gishyirwa.
Mu ruziga, zunguza umugozi w'umuyoboro inshuro nyinshi iburyo, uzunguze igikoresho igice kimwe gusa.

Shyira imbaraga z'iburyo ku mugozi w'imashini kandi ushyire uburemere ku migozi ikoreshwa mu gukata.Hagarika kumanura umugozi w'umuyoboro, uwuzungurutse ibumoso, hanyuma urekure imbaraga z'iburyo. Ubusanzwe, 1/2 cy'izunguruka ry'umuyoboro buri metero 300 kirahagije, kandi ntikigomba kurenza umubare w'izunguruka ry'iburyo mu gihe cyo gushyiraho.

Mu gihe ukoresha torque y'iburyo, shyira umugozi w'imashini ku gipakira, ushyire igikoresho mu mwanya wacyo usabwa wo gukora.

Fungura valve izenguruka hanyuma ukomeze gukoresha amazi, uzengurutse umugozi w'umuyoboro iburyo, hanyuma uwuzamure; shyira igitutu ku muyoboro hanyuma ukomeze kuzamura kugeza igihe amazi azenguruka. Noneho fata muri uyu mwanya, shyiramo amazi, hanyuma urekure umugozi w'umuyoboro kugeza igihe igitutu cy'amazi kirangiye, ureke igikoresho gitangira gutwara uburemere. Zengurutsa ibumoso hanyuma urekure imbaraga, hanyuma ukomeze kugabanya uburemere kugeza igihe umupakira wongeye gushyirwa hamwe n'icyo wifuza.

Urangije gupima no kurekura agapaki, banza ushyiremo imbaraga ku gapaki. Hanyuma, uzamura umugozi w'umuyoboro utawuzungurutse, bityo ukomeze gufunga valve kandi ushyireho uruziga rw'inyuma ruzengurutse agapaki.

Manura umuyoboro, zungurutsa umugozi w'umuyoboro, hanyuma uwuzamure, bityo ukingura valve izenguruka, hanyuma igikoresho gishobora gukurwa mu mutwe w'iriba.
