Umehluko Phakathi Kwama-Cement Retainers nama-Bridge Plugs

Ukubhola Nokugaya Indlela Engcono Kakhulu:

Uma isimo ukwenza ukubhola nomaimisebenzi yokugaya(isigayo sikadoti), umkhuba onconyiwe umi kanje:

• Sebenzisa aI-tricone Bit(I-IADC Bit Amakhodi2-1, 2-2, 2-3, 2-4, no-3-1) - ukwakheka okuqinile okuphakathi.Idatha ye-PDCakunconyelwa.
• I-RPM engcono kakhulu izoba ngu-70 kuya ku-125
• Sebenzisa i-viscosity yodaka engu-60 CPS ekususeni ukusikwa
• Isisindo kubhithi - Faka ama-5-7 Klbs. Kuze kube sekugcineni phezulu mandrel ibhobozekile kude, okuyinto 4-5 amayintshi. Bese wengeza u-3 Klbs. yesisindo intshi ngayinye kasayizi omncane ukubhoboza ingxenye esele. Isibonelo: 4-1/2 bit izosebenzisa 9,000-13,500 lbs. isisindo.
• Ungafaki isisindo phezu kwenani elinconyiwe. Isisindo esingenangqondo singadabula izingcezu ze-Bridge Plug, futhi ukwenza olunye uhambo kuyoba isibopho ukususa izingcezu ukuze kuvunyelwe ukungena okwengeziwe.
• I-Drill Collars- izosetshenziswahlinzeka nge-WOB edingekayofuthiI-drilling bitIsibonelo: 4-1/2 thru 5-1/2 (8 imiz.) 7 nangaphezulu (12 imiz.).
• Obhasikidi Abangafuneki- Kuzosetshenziswa ubhasikidi owodwa noma ngaphezuluintambo yokubhoboza. Uma kuhlelwa ukujikeleziswa kwe-reverse, noma yimaphi amathuluzi kushubhu noma intambo yokubhoboza kufanele abe ne-ID efanayo yebhithi ukuze ukusikwa kungabi ibhuloho.
• I-Anular Velocity- 120 ft/min kufanele kucatshangelwe.
• Ubhasikidi kadoti ngenhla kwebhithi.

Amathuluzi Adingekayo Ukusetha Nokusevisa

• Ikhithi ye-adaptha yocingo
• I-Stinger Seal Assembly
• I-Tubing Centralizer
• Ithuluzi Lokusetha Lomshini
• Ikhithi ye-adaptha yocingo ye-Flapper Bottom
• Ithuluzi Lokusetha I-Hydraulic

Ukusetha I-Bridge Plug Nezindlela Zokukhipha

Ngempela, ukusetha kanye nezindlela zokubuyisa zizohluka kumkhiqizi nomkhiqizi. Kodwa, sethula inqubo evamile ukuze uthole umbono.

I-Tension Set

Gijimani ekujuleni okudingekile ngenkathi kuxhunywe ethuluzini lakho lokubuyisa.

Thatha, zungezisa XX (1/4) jikela kwesokudla kupulaki, bese wehlisa ishubhu ukuze usethe ama-slip aphansi.

Donsa ukungezwani okwanele ukuze upakishe izinto, nciphisa, bese uyaphakamisa futhi ukuze uqinisekise ukulungiselelwa kwepulaki (15,000 kuya ku-20,000 lbs).

Ngemva kokusetha ipulaki, nciphisa isisindo seshubhu, ubambe itorque engakwesokunxele, bese uthatha ukuze ukhulule ithuluzi elisebenzayo kupulaki.

Isethi Yokucindezela

Gijimela ekujuleni okudingekile ngenkathi uxhunywe ethuluzini lokubuyisa.

Thatha, zungezisa XX (1/4) jikela kwesokudla kupulaki, bese wehlisa ishubhu ukuze usethe ama-slip aphansi.

Yehlisa isisindo esanele ukuze upakishe izinto, bese uthatha ukuze usethe ngokuqinile iziliphu eziphezulu bese uhlehle futhi (15,000–20,000 lbs).

Ngemva kokusetha ipulaki, nciphisa isisindo seshubhu, ubambe itorque engakwesokunxele, bese uthatha ukuze ukhulule ithuluzi elisebenzayo kupulaki.

Inqubo Yokukhipha

Amashubhu aphansi kuze kube umaka wethuluzi lokubuyisa kupulaki yebhuloho futhi unamathisele okufanayo.

Zungezisa ukuze ugeze isihlabathi kumapulaki.

Vula i-valve yokudlula ngokunciphisa isisindo, ubambe i-torque engakwesokudla, bese uphakamisa.

Linda ukulinganisa kwengcindezi.

Donsela phezulu ukuze ukhulule iziliphu, phumuza izinto zokupakisha, futhi ubophe kabusha.

Ipulaki manje ingase ikhululeke ukunyakaza.

Uma ipulaki ingeke idedele ngokwejwayelekile, xegise, sethe kabusha, bese udonsa ukuze ugunde ama-J-pins bese ukhulula ipulaki (ama-J-pin azosheka ngo-40,000 kuya ku-60,000 lbs ngalinye).

Uma usuphumelele ukugunda izikhonkwane, ithuluzi ngeke likwazi ukuhambisa phansi.

Izici Ezibalulekile Ze-Bridge Plug Ongacabanga Ngazo

Amapulagi amaningi ebhuloho eza ne-by-pass enkulu yangaphakathi ukuze unciphise umphumela wokuswabha we-RIH & POOH. Le bypass ivula ngaphambi kokukhulula ipulaki ukwenza ukulinganisa kwengcindezi. Amanye ama-BP nawo anekhono lokusetha nokupakisha into ekucindezelekeni.

Ukuqina kwethuluzi nakho kufanele kucatshangelwe ukuze konge isikhathi nezindleko zokusebenza.

Amanye amathuluzi eza nesici sokuguqulela kwisigcinali sikasimende noma ukusuka kusethi yomshini ukuya kusethi yezintambo.

Ukucaciswa okuhle phakathi kwepulaki yebhuloho kanye ne-casing kufanele kucatshangelwe futhi njengokusebenza okusheshayo nokuphephile ngaphandle kokusetha kungazelelwe.

Kukhona imiklamo ethile evimbela ukunyakaza ngenxa yeziliphu eziphikisanayo. Lesi sici siqinisekisa ukuthi ngeke kube khona ukunyakaza uma kwenzeka ingcindezi ehlukile ikhuphukela ngaphakathi nasendleleni (phezulu noma phansi).

Amapulagi ebhuloho angamathuluzi abalulekile omgodi ophansi asetshenziswa ekusebenzeni kukawoyela negesi ukulinganisa ingcindezi, ukushiywa kwesikhashana, kanye nokuhlukaniswa kwendawo. Kunezinhlobo eziningana zamapulaki ebhuloho atholakalayo ukuze afanele izinhlelo zokusebenza ezihlukahlukene. Uhlobo ngalunye lunezici zalo ezihlukile kanye nezinzuzo ezilwenza lufanelekele izinhlobo ezithile zokusebenza. Ukusebenzisa uhlobo olulungile lwepulaki yebhuloho kunganciphisa kakhulu isikhathi sokusebenza futhi kuqinisekise ukuhlolwa kwengcindezi okuphumelelayo.

Uma unentshisekelo ngemikhiqizo yochungechunge lwepulaki yebhuloho le-Vigor, sicela ungangabazi ukuxhumana nathi ukuze uthole imikhiqizo esezingeni eliphezulu kakhulu kanye nenkonzo yekhwalithi engcono kakhulu.
