Cement Bond Log ke eng?

Samente Bond Log: E lekanya botšepehi ba maqhama a samente pakeng tsa li-tubing / casing le bore ea seliba. Log hangata e fumanoa ho e 'ngoe ea lisebelisoa tse fapaneng tsa mofuta oa sonic. Liphetolelo tse ncha, tse bitsoang "mapa a samente", li ka fana ka litlhaloso tse qaqileng, tsa 360-degree tsa botšepehi ba mosebetsi oa samente, athe liphetolelo tsa khale li ka hlahisa mola o le mong o emelang botšepehi bo kopanetsoeng ho pota-pota casing (sheba Setšoantšo se ka tlase).

Khopolo ea CBL:Transmitter e romella leqhubu la acoustic ho casing/samente ebe ba amohelang ba amohela lets'oao la acoustic le fetisang ka casing ho ea samente ebe le bonts'a ho ba amohelang. Acoustic wave ho ba amohelang e fetoleloa ho amplitude (mv). Amplitude e tlaase e emela tlamo e ntle ea samente pakeng tsa casing le lesoba; leha ho le joalo, amplitude e phahameng e emela tlamo e mpe ea samente. Khopolo e rata ha re kokota phala. Haeba ho na le ho hong ho koaheletsoeng haufi le phala, molumo o bonahatsang o tla fokotsoa, ​​'me ka tsela e fapaneng (sheba setšoantšo se ka tlase).

Karolo ea lisebelisoa bakeng sa CBL hajoale hangata e na le lisebelisoa tse latelang:

Gamma Ray/CCL:E sebelisoa e le sebaka sa ho hokahanya. Lehlaseli la Gamma le lekanya mahlaseli a tlhaho 'me CCL e tlaleha botebo ba molala ka har'a li-tubing. Correlation log ke sesupo sa mesebetsi e mengata ea likoti tse kang perforation, set plug, set patch, joalo-joalo.

CBL/VDL:CBL e lekanya botšepehi ba bonto ea samente lipakeng tsa casing/tubing le seliba. E sebetsa mohopolo oa acoustic wave e fetisang ka media. VDL ke chebahalo e holimo ea ho khaoha ha karolo e kaholimo ea leqhubu la acoustic le emelang hore na bond ea samente ho tloha mokotleng ho ea ho seliba.

Caliper:Caliper e lekanya bophara ba liliba.

Mohlala oa CBL o bontšitsoe ka tlase

Maemo a tlase a ka bakang liphoso tlhalosong kapa ho ts'epahala ha acoustic CBL ke a latelang:

• Botenya ba sheath ea samente: Botenya ba samente bo ka fapana, bo baka liphetoho ho sekhahla sa ho fokotsa. Botenya bo loketseng ba samente ba 3/4 in. (2 cm) kapa ho feta bo hlokahala ho fihlela ho fokotsoa ka botlalo.
• Microannulus: Microannulus ke lekhalo le lenyane haholo lipakeng tsa casing le samente. Lekhalo lena le tla ama tlhahiso ea CBL. Ho matha CBL tlas'a khatello ho ka thusa ho felisa microannulus.
• Sesebelisoa sa Centralize: Sesebelisoa se tlameha ho ba bohareng ho fumana amplitude e nepahetseng le nako.

Vigor's Memory Cement Bond Tool e etselitsoe ka ho khetheha ho hlahloba botšepehi ba maqhama a samente pakeng tsa casing le sebopeho. E finyella sena ka ho lekanya bophahamo ba sekontiri sa samente (CBL) e sebelisa li-receiver tse haufi tse behiloeng ka nako ea 2-ft le 3-ft intervals. Ho feta moo, e sebelisa seamoheli se hole se hole sa 5-ft ho fumana litekanyo tsa "density density log" (VDL).

Ho netefatsa tlhahlobo e felletseng, sesebelisoa se arola tlhahlobo ka likarolo tse 8 tsa angular, 'me karolo ka' ngoe e koahela karolo ea 45 °. Sena se nolofalletsa tlhahlobo e phethahetseng ea 360 ° ea botšepehi ba bonto ea samente, e fanang ka lintlha tsa bohlokoa tsa boleng ba eona.

Bakeng sa ba batlang litharollo tse ikhethileng, Vigor e boetse e fana ka sesebelisoa sa Cement Bond sa boikhethelo se lefelloang. Sesebelisoa sena se ka etsoa hore se finyelle litlhoko tse khethehileng 'me se ithorisa ka moralo oa sebopeho se kopanetsoeng, se hlahisang bolelele bo khuts'oanyane ba khoele ea sesebelisoa. Litšobotsi tse joalo li etsa hore e tšoanelehe ka ho khetheha bakeng sa lits'ebetso tsa ho rekota memori.
