Yintoni iSamente Bond Log?

I-Samente Bond Log: Ilinganisa imfezeko yebhondi yesamente phakathi kwetyhubhu/icasing kunye nokubhoreka. Ilog iqhele ukufunyanwa kwesinye sezixhobo ezahlukeneyo zohlobo lwe-sonic. Iinguqulelo ezintsha, ezibizwa ngokuba "yimephu yesamente", zinokunika iinkcukacha ezicacileyo, ii-360-degree ezibonisa ukuthembeka komsebenzi wesamente, ngelixa iinguqulelo ezindala zingabonisa umgca omnye omele imfezeko edibeneyo ejikeleze i-casing (jonga umfanekiso ongezantsi).

Ingqikelelo ye-CBL:I-Transmitter ithumela i-acoustic wave kwi-casing/samente kwaye emva koko abamkeli bafumana umqondiso we-acoustic ogqithiselwa kwi-casing ukuya kwisamente kwaye ubonakalisa kubamkeli. I-Acoustic wave kubamkeli iguqulwa ibe yi-amplitude (mv). I-amplitude ephantsi imele ibhondi yesamente elungileyo phakathi kwe-casing kunye nomngxuma; nangona kunjalo, i-amplitude ephezulu imele ibhondi yesamente embi. Ingqikelelo ithanda xa sinkqonkqoza umbhobho. Ukuba kukho into egqunyiweyo ejikeleze umbhobho, isandi esibonakalisayo siya kuthotywa, kwaye ngokuchaseneyo (jonga umfanekiso ongezantsi).

Icandelo lesixhobo se-CBL okwangoku libandakanya izixhobo ezilandelayo:

Gamma Ray/CCL:Isetyenziswa njengelog yonxulumano. Imitha yeGamma ilinganisa ukubunjwa kwemitha kwaye iCCL irekhoda ubunzulu bekhola kwityhubhu. Ilog yonxulumano sisalathiso senani lemisebenzi yomngxuma enecased njengokugqobhoza, iplagi yokuseta, isiziba sokuseta, njl.

CBL/VDL:I-CBL ilinganisa ukuthembeka kwebhondi yesamente phakathi kwecasing/ityhubhu kunye nokubhora. Isebenzisa ingqikelelo ye-acoustic wave yogqithiso ngemidiya. I-VDL yimbono ephezulu yokusikwa kwendawo ephezulu ye-acoustic wave emele indlela ibhondi yesamente ukusuka kwingxowankulu ukuya kumthombo

I-Caliper:I-Caliper ilinganisa ububanzi bomthombo.

Umzekelo we-CBL uboniswe ngezantsi

Iimeko ezisezantsi ezinokubangela iimpazamo kwi-acoustic CBL toliko okanye ukuthembeka zimi ngolu hlobo lulandelayo:

• Ubungqingqwa beshefu yesamente: Ubukhulu beshefu yesamente bunokwahluka, nto leyo ebangela utshintsho kwisantya sokuthomalalisa. Ubukhulu besamente obufanelekileyo be-3/4 in. (2 cm) okanye ngaphezulu bufunekayo ukufezekisa ukuthotywa ngokupheleleyo.
• I-Microannulus: I-microannulus yi-gap encinci kakhulu phakathi kwe-casing kunye ne-samente. Lo msantsa unokuchaphazela umboniso we-CBL. Ukuqhuba i-CBL phantsi koxinzelelo kunokunceda ukuphelisa i-microannulus.
• Isixhobo sokubeka kwindawo esembindini: Isixhobo kufuneka sibekwe kwindawo enye ukuze kufumaneke i-amplitude echanekileyo kunye nexesha.

I-Vigor's Memory Cement Bond Tool yenzelwe ngokukodwa ukuvavanya ingqibelelo yebhondi yesamente phakathi kwe-casing kunye nokwakheka. Ifezekisa oku ngokulinganisa i-sement bond amplitude (CBL) isebenzisa abamkeli abakufutshane ababekwe kuzo zombini izithuba ze-2-ft kunye ne-3-ft. Ukongeza, isebenzisa umamkeli omde kumgama we-5-ft ukufumana imilinganiselo ye-variable density log (VDL).

Ukuqinisekisa uvandlakanyo olubanzi, isixhobo sihlula uhlalutyo lube ngamacandelo angama-8 angama-angular, kunye necandelo ngalinye eligubungela icandelo le-45 °. Oku kuvumela uhlolo olucokisekileyo lwe-360 ° lwentembeko yebhondi yesamente, ibonelela ngeembono ezixabisekileyo kumgangatho wayo.

Kwabo bafuna izisombululo ezilungiselelwe wena, iVigor ikwabonelela ngesiXhobo seBond ye-sonic esihlawulelwayo. Esi sixhobo sinokulungelelaniswa ukuhlangabezana neemfuno ezithile kwaye siqhayisa uyilo lwesakhiwo esidibeneyo, esikhokelela kubude obufutshane obufutshane bomtya wesixhobo. Ezo mpawu ziyenza ilunge ngakumbi kwizicelo zokungena kwimemori.
