Kodi Logi ya Cement Bond ndi chiyani?

Chipika cha Cement Bond: Imayesa kukhulupirika kwa mgwirizano wa simenti pakati pa chubu / casing ndi kubowola bwino. chipikacho chimachokera ku chimodzi mwa zida zamtundu wa sonic. Mabaibulo atsopano, otchedwa "mapu a simenti", angapereke mwatsatanetsatane, ma degree 360 ​​a kukhulupirika kwa ntchito ya simenti, pamene matembenuzidwe akale angasonyeze mzere umodzi woimira kukhulupirika kophatikizidwa mozungulira casing (onani Chithunzi pansipa).

Malingaliro a CBL:Transmitter imatumiza ma acoustic wave ku casing/simenti kenako olandila amalandira ma acoustic sign omwe amasamutsidwa kudzera pa casing kupita ku simenti ndikuwonetsa kwa olandila. Acoustic wave pa olandila amasinthidwa kukhala matalikidwe (mv). matalikidwe otsika amayimira mgwirizano wabwino wa simenti pakati pa casing ndi dzenje; komabe, matalikidwe apamwamba amayimira mgwirizano woyipa wa simenti. Lingaliro limakonda tikagogoda chitoliro. Ngati chitoliro chatsekedwa mozungulira chitoliro, mawu onyezimira amachepetsedwa, ndipo mosemphanitsa (onani chithunzi pansipa).

Chida cha CBL pakadali pano chimakhala ndi zida izi:

Gamma Ray / CCL:Amagwiritsidwa ntchito ngati cholembera cholumikizira. Gamma ray imayesa kupangika kwa ma radiation ndipo CCL imalemba kuzama kwa kolala mu chubu. Logi yolumikizira nditanthauzo la ntchito zingapo zokhala ndi mabowo monga perforation, set plug, set patch, etc.

CBL/VDL:CBL imayesa kukhulupirika kwa simenti pakati pa casing/chubu ndi bore. Zimatengera lingaliro la ma acoustic wave kusamutsa kudzera pa media. VDL ndiye mawonekedwe apamwamba a kudulidwa kwa gawo lakumtunda kwa mafunde acoustic komwe kumayimira mayendedwe a simenti kuchokera ku casing kupita ku chitsime.

Caliper:Caliper amayesa kutalika kwa chitsime.

Chitsanzo cha CBL chikuwonetsedwa pansipa

Mikhalidwe yotsika yomwe ingayambitse zolakwika pakutanthauzira kapena kudalirika kwa coustic CBL ndi motere:

• Makulidwe a simenti ya simenti: makulidwe a simenti amatha kukhala osiyanasiyana, kupangitsa kusintha kwa kutsika. Makulidwe a simenti oyenera a 3/4 mainchesi (2 cm) kapena kupitilira apo amafunikira kuti achepetse.
• Microannulus: Microannulus ndi kampata kakang'ono kwambiri pakati pa casing ndi simenti. Kusiyanaku kungakhudze kafotokozedwe ka CBL. Kuthamanga CBL pansi pa kupanikizika kungathandize kuthetsa microannulus.
• Chida chapakati: Chidacho chiyenera kukhala chapakati kuti chipeze matalikidwe olondola ndi nthawi.

Chida cha Vigor's Memory Cement Bond chapangidwa makamaka kuti chiwunikire kukhulupirika kwa mgwirizano wa simenti pakati pa casing ndi mapangidwe. Imakwaniritsa izi poyeza matalikidwe a simenti (CBL) pogwiritsa ntchito zolandila pafupi ndi 2-ft ndi 3-ft intervals. Kuphatikiza apo, imagwiritsa ntchito cholandila chakutali pamtunda wa 5-ft kuti ipeze miyeso ya variable density log (VDL).

Kuti muwonetsetse kuwunika kokwanira, chidachi chimagawaniza kusanthula m'magawo 8 aang'ono, ndipo gawo lililonse limakhala ndi gawo la 45 °. Izi zimathandizira kuwunika kokwanira kwa 360 ° kwa kukhulupirika kwa chomangira cha simenti, kupereka zidziwitso zofunikira pazabwino zake.

Kwa iwo omwe akufuna mayankho makonda, Vigor imaperekanso mwayi wolipira sonic Cement Bond Tool. Chida ichi chikhoza kupangidwa kuti chikwaniritse zofunikira zenizeni ndipo chimadzitamandira kamangidwe kameneka, zomwe zimapangitsa kuti chingwechi chikhale chachifupi. Zoterezi zimapangitsa kuti zikhale zoyenera kwambiri pakugwiritsa ntchito kukumbukira mitengo.
