Chii chinonzi Cement Bond Log?

Cement Bond Log: Inoyera kutendeseka kwesimende chisungo pakati petubing / casing uye kubhowa. Iyo log inowanzo wanikwa kubva kune imwe yeakasiyana-siyana sonic-mhando maturusi. Idzi shanduro itsva, dzinonzi "cement mapping", dzinogona kupa tsanangudzo, 360-degree inomiririra yekuvimbika kwebasa resimende, nepo shanduro dzekare dzinogona kuratidza mutsara mumwe chete unomiririra kutendeseka kwakabatana kwakakomberedza casing (ona Figure pazasi).

Pfungwa yeCBL:Transmitter inotumira acoustic wave kune casing / simende uye ipapo vanogamuchira vanogashira acoustic chiratidzo chinotamisa kuburikidza necasing kune simende uye inoratidza kune vanogamuchira. Acoustic wave kune vanogamuchira inoshandurwa kuita amplitude (mv). Low amplitude inomiririra yakanaka simende chisungo pakati casing uye gomba; zvisinei, yakakwirira amplitude inomiririra yakaipa simende chisungo. Pfungwa inoda patinogogodza pombi. Kana paine chinhu chakavharika papombi, kurira kwekuratidzira kunodzikiswa, uye zvichipesana (ona Mufananidzo uri pazasi).

Chishandiso cheCBL parizvino chine midziyo inotevera:

Gamma Ray/CCL:Inoshandiswa sekubatanidza log. Gamma ray inoyera kuumbwa kwemwaranzi uye CCL inorekodha kudzika kwecollar muchubhu. Correlation log ireferensi yehuwandu hwemacased hole mabasa seperforation, set plug, set chigamba, nezvimwe.

CBL/VDL:CBL inoyera sement bond kuperera pakati pecasing/tubing nematsime. Inoshandisa pfungwa yeacoustic wave kutamisa kuburikidza nemedia. VDL ndiyo inotarisa pamusoro pekuchekwa kwechikamu chepamusoro cheacoustic wave inomiririra mabatirwo esimende kubva kubhegi kuenda kutsime.

Caliper:Caliper inoyera dhayamita yetsime.

Muenzaniso weCBL unoratidzwa pazasi

Downhole mamiriro anogona kukonzera kukanganisa mukududzira kweacoustic CBL kana kuvimbika ndeaya anotevera:

• Cement sheath ukobvu: Cement-sheath ukobvu hunogona kusiyana, zvichikonzera shanduko muyero yekudzora. Iyo yakakodzera simende ukobvu hwe 3/4 in. (2 cm) kana kupfuura inodiwa kuti uwane attenuation yakazara.
• Microannulus: A microannulus idiki mukaha pakati pecasing ne simenti. Mukaha uyu ungakanganisa kuratidzwa kweCBL. Kumhanyisa CBL pasi pekumanikidzwa kunogona kubatsira kubvisa iyo microannulus.
• Centralize chishandiso: Chishandiso chinofanirwa kuve nechepakati kuti uwane iyo amplitude chaiyo uye nguva.

Vigor's Memory Cement Bond Tool yakanyatsogadzirirwa kuongorora kuvimbika kwechisungo chesimende pakati pekasi uye maumbirwo. Inoita izvi nekuyera simende bond amplitude (CBL) ichishandisa pedyo nevagamuchiri vakamira pamativi ese maviri-ft uye 3-ft. Pamusoro pezvo, inoshandisa iri kure inogamuchira iri chinhambwe che5-ft kuwana iyo variable density log (VDL) zviyero.

Kuti ive nechokwadi chekuongorora kwakazara, chishandiso chinoparadzanisa kuongororwa muzvikamu zve8 angular, nechikamu chimwe nechimwe chinovhara chikamu che45 °. Izvi zvinogonesa kunyatsoongorora 360 ° yekuvimbika kwesemende bond, ichipa ruzivo rwakakosha mumhando yayo.

Kune avo vanotsvaga mhinduro dzakagadzirirwa, Vigor inopawo sarudzo yakabhadharwa sonic Cement Bond Tool. Ichi chishandiso chinogona kugadzirwa kuti chisangane nezvinodiwa uye chinozvirumbidza nedhizaini yedhizaini, zvichikonzera kureba kupfupi kwetambo yechishandiso. Hunhu hwakadai hunoita kuti ive yakanyanya kukodzera kune ndangariro matanda maapplication.

Kuti uwane rumwe ruzivo, unogona kunyorera kubhokisi redu retsambainfo@vigorpetroleum.com&marketing@vigordrilling.com
