Kodi Logi ya Cement Bond Imagwira Ntchito Bwanji?

CBL ndi ntchito yapadera yodula mitengo yomwe imachitidwa kuti adziwe kukhulupirika pakati pa casing-to-simenti ndi simenti-to-formation. CBL nthawi zambiri ikuchitika pambuyo cementing annulus chitsime ndi mwina 7 inchi kapena 9-5/8 inchi casing. Kuyika simenti, komabe, kumachitidwa pofuna kudzipatula kuti madzi asalowe m'madera omwe ali ndi matope omwe ali mu dziwe komanso kuti malo osungiramo madzi azikhala olimba. Ndizoyenera kudziwa kuti CBL yoyimiridwa ndi chithunzi pamwambapa, idayendetsedwa mu dzenje pogwiritsa ntchito GR + CCL + PACE chida cholumikizira. Kumene GR ndi Gamma Ray Log, CCL ndi Casing Coller Locator ndipo PACE ndi Pulsed Acoustic Cement Evaluation. Kusonkhanitsa zida ndizomwe zimathandiza kupanga ndikutanthauzira deta ya CBL.

GR Log imathandizira kuzindikira zolemba zosiyanasiyana pazitsime. Zimathandizanso kulumikizana pakati pa ma 2 GR Logs molingana ndi siginecha yakuzama yofananira. CCL imagwiritsidwa ntchito kupeza malo omwe oyimba aliyense ali pafupi ndi chitsime pomwe PACE imagwiritsidwa ntchito kupanga ndikutanthauzira siginecha ya matalikidwe, VDL - Variable Density Log komanso siginecha yamakanika. Gulu la zida za 3 zophatikizidwa zimalumikizidwa palimodzi ndikuthamangira mu dzenje mothandizidwa ndi mawaya omwe amaperekedwa.

Komabe, pali zinthu zitatu zofunika kudziwa ngati ntchito ya simenti pachitsime ikuchitika bwino kapena moyipa kwambiri. Kuti ntchito ya simenti ikhale yabwino komanso yopambana, ndiye kuti iyenera kukwaniritsa zinthu zitatu zomwe zikuphatikizapo: Low Amplitude, High Attenuation and Weak VDL. Kuchokera pazida za CBL zomwe zili pamwambapa, pali mizati isanu ndi umodzi iliyonse pazipika zonse ziwiri. Gawo lachitatu ndi gawo lachisanu la chipika choyamba, lili ndi matalikidwe otsika komanso VDL yofooka - kusonyeza ntchito yabwino kwambiri komanso yopambana ya simenti. Komano, ndime 3 ndi 5 ndime ya chipika 2, ali mkulu matalikidwe ndi VDL wamphamvu - kusonyeza osauka kwambiri simenti ntchito.

Ndi kutanthauzira uku, zitha kudziwika kuti ntchito ya simenti yolembedwa ndi CBL pa chipika choyamba ikukwaniritsa zofunikira za ntchito yabwino ya simenti. Pamene chipika chachiwiri chinalephera zikhalidwe za ntchito yabwino ya simenti. Choncho, tikulimbikitsidwa kuti pa ntchito iliyonse ya simenti yomwe ikuchitika, CBL iyendetsedwe kuti iwonetsetse kukhulupirika kwa simenti pachitsimepo. Ndi izi, kampaniyo imatha kudziwa momwe ingapitirire ndi ntchito zomwe zikubwera.

Chida cha Vigor's Memory Cement Bond chimayesa kukhulupirika kwa bond ya simenti poyesa Cement Bond Amplitude (CBL) ndi olandila pafupi ndi 2-ft ndi 3-ft intervals ndikugwiritsa ntchito cholandila kutali pa 5-ft pamiyezo ya Variable Density Log (VDL). Imapereka kuwunika kokwanira kwa 360 ° pogawa kuwunikirako m'magawo 8 aang'ono, chilichonse chimakhala ndi 45 °. Timaperekanso chida cholipiridwa cha sonic Cement Bond Tool chokhala ndi kapangidwe kocheperako, koyenera kugwiritsa ntchito kudula mitengo pamtima.

Ngati muli ndi chidwi ndi Memory Cement Bond Tool kuchokera ku Vigor kapena zida zina zobowola ndikumaliza kudula mitengo yamafuta & gasi, chonde musazengereze kutilumikizana nafe kuti mupeze malonda apamwamba kwambiri komanso ntchito zabwino kwambiri.
