5. Ubwino wa RTTS Packer

Chopakira cha RTTS ndi chimodzi mwa zida zomwe zimagwiritsidwa ntchito kwambiri poyesa zitsime. Chimagwiritsidwa ntchito makamaka pazitsime zopanda mphamvu zambiri komanso zolowa madzi pang'ono komanso zitsime zamafuta olemera (zitsime zosayenda madzi) zomwe zawonongeka kwambiri panthawi yobowola, kuyika simenti, kapena ntchito zina. Zitsime zotere nthawi zambiri zimataya zinthu zambiri, zomwe zimafuna nthawi yayitali yoyesera komanso maulendo angapo obwerera kuti zipeze magawo olondola amadzimadzi ndi mapangidwe.

Chosungira cha RTTS chimalola ntchito zosiyanasiyana zophatikizana, kuphatikizapo:
Kuyesa kwa TCP (Tubing Conveyed Perforating) + MFE (Multi-Flow Evaluator)

Kuyesa kwa TCP + MFE + JET (hydraulic pump discharge)

Ntchito za TCP + MFE + JET + acidization

Chosungira cha RTTS n'chosavuta kugwiritsa ntchito, chotsika mtengo, chimachepetsa kwambiri ndalama zogwirira ntchito, ndipo chimapereka zabwino zambiri zachuma komanso zachikhalidwe.

Chopakira cha RTTS ndi chopakira chathunthu, chopachikidwa chomwe chimagwiritsidwa ntchito poyesa, kuchiza, ndi ntchito zopopera simenti. Nthawi zambiri, chimagwiritsidwa ntchito limodzi ndi cholumikizira cha valavu yozungulira. Thupi la chopakira limaphatikizapo makina a J-slot, zopopera zamakina, chinthu chopakira, ndi zopopera za hydraulic. Zopopera zazikulu, zolemera mu hydrauliclock zimathandiza kupewa kuti chida chisapompedwe m'bowo. Pa matupi a chopakira ≤ 3½″ (88.9 mm), kasupe wokoka umagwiritsa ntchito njira ya J-slot, pomwe zopopera zimagwiritsidwa ntchito pa kukula ≥ 4″ (101.6 mm). Matupi onse a chopakira ali ndi chopopera cha J-slot chokha monga muyezo. Ngati valavu yozungulira imagwiritsidwa ntchito, imakhala yamtundu wa lock-open/lock-close ndipo imagwira ntchito ngati circulating ndi bypass valve. Chopakira chikayikidwa, valavu imatseka yokha pamalo otsekedwa. Pakuyesa kapena kupopera simenti, loko imaletsa valavu kuti isapompedwe. Malo olunjika a J omwe ali pamalo otseguka otsekeka amafanana ndi malo olunjika a J omwe ali m'thupi la packer (ngati mukufuna). Kuphatikiza kumeneku kumachotsa kufunika kozungulira chubu kuti mutseke valavu yozungulira kapena kubwezeretsanso packer mutachotsa simenti.
