Iyini i-Cement Bond Log?

I-Cement Bond Log: Ikala ubuqotho besibopho sikasimende phakathi kweshubhu/ibhokisi nokubhoboza kahle. Ilogi ngokuvamile itholakala kwelinye lamathuluzi ahlukahlukene ohlobo lwe-sonic. Izinguqulo ezintsha, ezibizwa ngokuthi “imephu kasimende”, zinganikeza izethulo ezinemininingwane, ezingama-360-degree zobuqotho bomsebenzi kasimende, kuyilapho izinguqulo ezindala zingabonisa umugqa owodwa omelela ubuqotho obuhlanganisiwe eduze kwekesi (bona Umfanekiso ngezansi).

Umqondo we-CBL:I-Transmitter ithumela i-acoustic wave ku-casing/kusimende bese kuthi abemukeli bathole isignali ye-acoustic edluliswa nge-casing iye kusimende futhi ibonise kubamukeli. I-Acoustic wave kwabemukeli iguqulelwa ku-amplitude (mv). I-amplitude ephansi imelela isibopho esihle sikasimende phakathi kwe-casing nembobo; Nokho, amplitude high imele ezimbi usimende isibopho. Umqondo uthanda uma sishaya ipayipi. Uma kukhona okuvalekayo eduze kwepayipi, umsindo obonisayo uzoncishiswa, futhi okuphambene nalokho (bona Umfanekiso ngezansi).

Ingxenye yamathuluzi e-CBL okwamanje iningi lazo liqukethe izinto ezilandelayo:

I-Gamma Ray/CCL:Isetshenziswa njengelogi yokuhlanganisa. I-Gamma ray ikala ukwakheka kwemisebe futhi i-CCL irekhoda ikhola ukujula kushubhu. Ilogi yokuxhumanisa iyireferensi yemisebenzi eminingi yembobo enamakesi njengokubhoboza, ipulaki emisiwe, isichibi sokusetha, njll.

I-CBL/VDL:I-CBL ikala ubuqotho bebhondi kasimende phakathi kwebhokisi/ishubhu kanye nokubhoboza amanzi. Kusebenza umqondo wokudluliswa kwegagasi le-acoustic ngemidiya. I-VDL iwukubuka okuphezulu kokusikwa kwengxenye engenhla ye-acoustic wave emele ukuthi ibhondi kasimende ukusuka egodini kuye emthonjeni

I-Caliper:I-Caliper ikala ububanzi bomthombo.

Isibonelo se-CBL sikhonjiswe ngezansi

Izimo ze-Downhole ezingabangela amaphutha ekutolikweni kwe-acoustic CBL noma ukwethembeka zimi kanje:

• Ukujiya kwesigxobo sikasimende: Ukujiya kwegobolondo likasimende kungase kuhluke, kubangele izinguquko kuzinga lokunciphisa. Ugqinsi olufanele lukasimende lwe-3/4 in. (2 cm) noma ngaphezulu luyadingeka ukuze kuzuzwe ukuthotshiswa okugcwele.
• I-Microannulus: I-microannulus igebe elincane kakhulu phakathi kwe-casing nosimende. Lesi sikhala singathinta isethulo se-CBL. Ukusebenzisa i-CBL ngaphansi kwengcindezi kungasiza ekuqedeni i-microannulus.
• Ithuluzi lokubeka endaweni eyodwa: Ithuluzi kufanele libe phakathi nendawo ukuze lithole ubukhulu obunembile nesikhathi.

I-Vigor's Memory Cement Bond Tool yakhelwe ngokukhethekile ukuhlola ubuqotho besibopho sikasimende phakathi kwe-casing kanye nokwakheka. Ifeza lokhu ngokulinganisa i-amplitude yebhondi kasimende (CBL) isebenzisa izamukeli eziseduze ezibekwe kuzo zombili izikhawu ze-2-ft kanye ne-3-ft. Ukwengeza, isebenzisa isamukeli esikude esibangeni elingu-5-ft ukuze ithole izilinganiso zelogi ye-variable density (VDL).

Ukuqinisekisa ukuhlola okuphelele, ithuluzi lihlukanisa ukuhlaziya libe izingxenye ezingu-8 ze-angular, ingxenye ngayinye ihlanganisa ingxenye engu-45°. Lokhu kunika amandla ukuhlolwa okuphelele okungu-360° kobuqotho bebhondi kasimende, okuhlinzeka ngemininingwane ebalulekile ngekhwalithi yayo.

Kulabo abafuna izixazululo ezenziwe ngokwezifiso, i-Vigor iphinde inikeze ngethuluzi le-sonic Cement Bond elinxeshezelwa ngokuzikhethela. Leli thuluzi lingenziwa ngendlela efanele ukuze lihlangabezane nezidingo ezithile futhi liziqhayisa ngokuklama kwesakhiwo esihlangene, okuholela ekubeni bufushane bonke ubude beyunithi yezinhlamvu yamathuluzi. Izici ezinjalo ziyenza ifaneleke kakhulu izinhlelo zokusebenza zokungena kwimemori.
