Isebenza Kanjani Ilogi Yebhondi Yesimende?

I-CBL wuhlelo olukhethekile lokugawulwa kwemithi olwenziwa ukuze kunqunywe ubuqotho bebhondi phakathi kwe-casing-to-cement kanye ne-cement-to-formation. I-CBL ivamise ukwenziwa ngemuva kokufaka usimende i-annulus yomthombo okungenzeka ukuthi inekheseji engamayintshi angu-7 noma angu-9-5/8. Ukufakwa kukasimende nokho, kwenzelwa inhloso yokuhlukanisa ukuze kugwenywe ukungena kwamanzi ezindaweni ezinezimbobo echibini kanye nokuqina kwendawo yokugcina amanzi. Kuyafaneleka ukuqaphela ukuthi i-CBL emelwe ngesithombe ngenhla, yafakwa emgodini kusetshenziswa ukuhlanganiswa kwamathuluzi e-GR + CCL + PACE. Lapho i-GR iyi-Gamma Ray Log, i-CCL iyi-Casing Coller Locator futhi i-PACE iyi-Pulsed Acoustic Cement Evaluation. Ukuhlanganiswa kwamathuluzi yikho okusiza ukukhiqiza kanye nokutolika idatha ye-CBL.

I-GR Log isiza ukuhlonza ama-lithologies ahlukahlukene kuwo wonke umthombo. Kuphinde kusize ekuhlobaneni phakathi kwamalogi angu-2 ahlukene e-GR mayelana nokujula okuhambisana namasignesha elogi. I-CCL isetshenziselwa ukuthola indawo yabashayi bezingcingo be-casing ngayinye eduze komthombo kuyilapho i-PACE isetshenziselwa ukukhiqiza nokuhumusha amasiginesha okungena obude, i-VDL - Ilogi Yokuminyana Okuguquguqukayo kanye nesiginesha yelogi yokucindezeleka. Ukuhlanganiswa kwamathuluzi angu-3 kuhlanganisiwe kuxhunywe ndawonye futhi kugijime emgodini ngosizo lweyunithi yocingo oludluliswayo.

Noma kunjalo, kunezimo ezintathu eziyisisekelo zokunquma ukuthi umsebenzi kasimende emthonjeni wenziwa ngempumelelo noma kabi kakhulu. Ukuze umsebenzi usimende ube muhle futhi uphumelele, khona-ke kufanele uhlangabezane nezimo ezi-3 ezihlanganisa: I-Amplitude Ephansi, I-High Attenuation kanye ne-VDL Ebuthakathaka. Kusukela kudatha ye-CBL engenhla, kunamakholomu ayisithupha lilinye kuwo womabili amalogi. Ikholomu yesi-3 kanye nekholomu yesi-5 yelogi yoku-1, ine-amplitude ephansi kanye ne-VDL ebuthakathaka - ekhombisa umsebenzi omuhle kakhulu futhi ophumelelayo we-cement. Ngakolunye uhlangothi, ikholomu yesi-3 kanye nekholomu yesi-5 yelogi yesi-2, ine-amplitude ephezulu ne-VDL eqinile - okubonisa umsebenzi ompofu kakhulu wokuhlanganisa.

Ngale ncazelo, kungatholakala ukuthi umsebenzi kasimende njengoba ulotshwe yi-CBL kulogi lokuqala uyahlangabezana nemibandela yomsebenzi omuhle usimende. Ngenkathi i-log yesibili yehluleka imibandela yomsebenzi omuhle kasimende. Ngakho-ke, kunconywa kakhulu ukuthi kuwo wonke umsebenzi kasimende owenziwayo, kufanele kuqhutshwe i-CBL ukuze kunqunywe ubuqotho bebhondi kasimende endaweni yomthombo. Ngalokho, inkampani ingakwazi ukunquma indlela engcono kakhulu yokuqhubeka nemisebenzi ezayo.

Ithuluzi le-Vigor's Memory Cement Bond lihlola ubuqotho bebhondi kasimende ngokukala i-Cement Bond Amplitude (CBL) nabamukeli abaseduze ngezikhathi eziyi-2-ft kanye ne-3-ft futhi isebenzisa isamukeli esikude ku-5-ft ukuze kukale i-Vaable Density Log (VDL). Inikeza ukuhlola okuphelele okungu-360° ngokuhlukanisa ukuhlaziya kube izingxenye ezingu-8 ezingama-angular, ngayinye ihlanganisa u-45°. Siphinde sinikeze ngethuluzi le-sonic le-Cement Bond elinxeshezelwa ngendlela oyifisayo elinomklamo ohlangene, olungele izicelo zokugawulwa kwenkumbulo.

Uma unesithakazelo kuThuluzi le-Memory Cement Bond elivela ku-Vigor noma amanye amathuluzi okumba nokuqeda ukugawula embonini kawoyela negesi, sicela ungangabazi ukusithinta ngemikhiqizo esezingeni eliphezulu kakhulu kanye nenkonzo yekhwalithi engcono kakhulu.
