Cement Retainer Plug In Oil & Gas Well Guide

Zida zogwiritsira ntchito inflatable zakhala zikugwiritsidwa ntchito m'makampani amafuta ndi gasi kwazaka zopitilira 50 kuti agwire ntchito zosiyanasiyana zokonzanso. Zopanda mpweyabwino mapaketi,mapulagi mlatho, ndi chosungira simenti chimagwiritsidwa ntchito m'mabowo otseguka, mabowo otsekedwa, otsekedwa zikopa zamatabwa, ndi zowonetsera miyala yamtengo wapatali m'zitsime zamafuta ndi gasi, koma ziyenera kugwiritsidwa ntchito pokhapokha ngati zida wamba sizili zoyenera. Zosungira za simenti zimagwiritsidwa ntchito kwambiriZokonza zokonza simenti. Zosungira zobowolezazi zimayikidwa motetezeka mu chilichonsemtundu wa casing.

Zida zogwiritsira ntchito inflatable zimakhala zothandiza makamaka pamabowo otseguka a kukula kosatsimikizika. Monga mapaketi wamba (onaninsoPermanent Packers) ndi mapulagi a mlatho, zida zogwiritsira ntchito inflatable zitha kukhazikitsidwa mumagulu aliwonse (ie,chonyamula chobweza, resettable packer, retrievable bridge plug, and simenti retainer), kulola kuti ntchito zomwezo zichitike ngati zida wamba.

Inflatable simenti retainer Kuphatikiza msonkhano wa flapper-valve ndi mlatho wokhazikika wa inflatable umapanga chosungira simenti. Zosungira za simenti nthawi zambiri zimagwiritsidwa ntchito kufinya zopangira zosafunikira kapena ngalande za gasi pakati pa dzenje lotseguka ndi posungira. Pulagi ya ng'ombe yapansi imachotsedwa ndikusinthidwa ndi mpando wa mpira wometa ubweya. Lifti sub (Kubowola Subs) pamwamba amasinthidwa ndi msonkhano wa valve.

Chosungira cha simenti cha inflatable chimalola simenti kuti ipopedwe munjira. Simenti ikakhazikika, ndiye kutihydrostatic pressureimatsitsimutsidwa potulutsa chosungira. Mukatuluka mu chosungira, valavu imatseka ndipo salola kufinya kwina.

Kuzungulira Finyani

Kufinya kozungulira kumachitika nthawi zambiri ndi chosungira simenti m'malo mwa paketi. Kuzungulira kumatheka ndi madzi kapena asidi ngati madzi oyambira. Nthawiyi imazunguliridwa ndi madzi ochapira kuti ayeretse bwino, ndipo matope a simenti amapopedwa ndikuchotsedwa.

Palibe kukakamiza komwe kumachitika panthawi ya ntchito, kupatulapo kuwonjezeka komwe kumachitika chifukwa cha kupanikizika kwa hydrostatic pagawo la simenti pamene ikukwera pamwamba pa annulus. Kuyikako kukamalizidwa, mbola kapena paketi imatulutsidwa. Simenti yochulukirapo yomwe imazungulira kuchokera kumtunda wapamwamba imatha kusinthidwa ngati ingafune.

Kuchuluka kwa slurry komwe kumafunikira kumaliza kufinya kozungulira sikudziwika; Choncho, slurry zambiri zakonzedwa. Chifukwa chake, pali kuthekera kwakukulu kuti matope ena a simenti amatha kulowa m'bokosi,kubowola chitoliro, kapena chubu kapena annulus pamwamba pa chida chofinya panthawi ya ntchito.

Ngati simenti iyi itayikidwa, chitoliro chobowola (kapena chubu) chikhoza kukhazikika mu dzenje. Chifukwa chake, kuti muchepetse ngoziyi, chosungira simenti chiyenera kuyendetsedwa m'malo mwa paketi. Ndikosavuta kuchotsa gulu la mbola kusiyana ndi paketi, chifukwa chomalizacho chimakhala ndi chilolezo chochepa cha casing. Chosungiracho chiyenera kukhazikitsidwa pafupi kwambiri ndi ma perforations apamwamba. Izi zimachepetsa kukhudzana kwa chitoliro chobowola ku matope a simenti omwe angalowe m'chitsime kudzera m'mabowo apamwamba.

Simenti Finyani

Cement Retainer imagwiritsidwanso ntchitokuphwanya simentintchito. Kugwiritsiridwa ntchito kwake kumatengedwa kuti ndi imodzi mwa mitundu ya njira zoyika zida za Squeeze. Njirayi ikhoza kugawidwa m'magawo awiri - njira yobweretsera yofinyidwa komanso njira yobowoleza simenti. Cholinga chachikulu chogwiritsira ntchito zida zofinya ndikupatula casing ndi mutu pomwe mukugwiritsira ntchito kutsika kwamphamvu.

Zosungira za simenti ndi mapaketi obowoleza omwe ali ndi valavu yomwe imayendetsedwa ndi mbola kumapeto kwa chingwe chogwirira ntchito (Fig.1). Zosungira za simenti zimagwiritsidwa ntchito poletsa kubweza kwa simenti pamene palibe kuchepa kwa simenti komwe kumayembekezeredwa kapena pamene kusiyana kwakukulu kosiyana kungasokoneze keke ya simenti. Nthawi zina, kugwiritsa ntchito paketi kumakhala kowopsa chifukwa cholumikizana ndi ma perforations apamwamba. Pomanga madera angapo, chosungira simenti chimapatula ma perforations apansi ndipo kufinya kotsatira kumatha kuchitika popanda kuyembekezera kuti slurry ikhazikike.

Chosungira chobowoleza chimapatsa wogwiritsa ntchito chidaliro chowonjezereka pakuyika paketi pafupi ndi zoboola. Ubwino winanso ndikuti kuchuluka kwamadzi pang'ono m'munsi mwa paketi kumasunthidwa kudzera m'mabowo kutsogolo kwa slurry ya simenti.

Gulu la Vigor lidzatulutsa mankhwala athu atsopano WIDE RANGE BRIDGE PLUG posachedwa, ngati mukufuna kudziwa zambiri za izo, chonde musazengereze kulumikizana nafe kuti tipeze chithandizo chaukadaulo chaukadaulo komanso chithandizo chamankhwala.
