Anti-Channeling Agent

Peb cov tshuaj tiv thaiv-channeling tus neeg saib xyuas npog ob qib: latex-raws li FC-AG1L rau qhov dej qis dua 150℃thiab nano silicon FC-AG02L rau siab- qhov dej kub txog li 230℃. Tsim los nres cov pa roj & dej channeling thaum lub sij hawm tsim cov cement, ntxiv dag zog rau cov cement sheath kev ncaj ncees, peb muab cov qauv kuaj sim thiab kev cai tsim rau ntiaj teb onshore & offshore cementing tej yaam num.

Gas channeling tseem yog ib qho ntawm feem ntau pheej yig tsis ua hauj lwm hauv thawj qhov dej cementing. Thaum cov cement slurry hloov los ntawm cov kua rau hauv lub xeev gel, qhov poob ntawm hydrostatic siab ib txwm cia cov roj nyem los ntawm cov pores me me hauv cov cement uas tsis muaj teeb meem, ua rau muaj kev kub ntxhov siab, annular to, thiab txawm tias mus tas li zoo tso tseg.

Tau ntau xyoo lawm, peb cov engineers teb tau sib tw los tiv thaiv -gas migration additive rau pua pua ntawm cov roj & roj qhov dej nyob hauv qhov dej ntiav qis- qhov kub thiab txias thiab qhov tob tob -kub reservoirs. Peb tau tsim ob qho qauv tsim kom haum rau qhov sib txawv ntawm qhov chaw ua haujlwm, tsis yog siv ib qho khoom siv thoob ntiaj teb rau txhua hom zoo.

FC-AG1L: Latex Anti-Channeling Agent rau Medium & Low Temperature Wells

FC-AG1L yog tsim los ntawm butylbenzene latex, peb tus nqi - siv tau los tiv thaiv - channeling tov tsim rau qhov dej nrog BHCT qis dua 150℃.

Hauv daim ntawv thov teb, peb pom cov pa cement feem ntau tig nkig tom qab kho. Thaum lub qhov dej nkag mus hydraulic fracturing los yog ntev -lub sij hawm tsim siab hloov pauv, micro tawg yooj yim tsim hauv cov cement sheath thiab tsim cov dej ntws rau cov roj thiab cov dej tsim. Qhov no latex - hom zoo cementing additive hloov kho qhov yooj yim ntawm cov cement remarkably.

Sib nrug los ntawm kev tiv thaiv- channeling kev ua tau zoo, cov khoom no muab cov kua dej tsis ruaj khov thaum sib xyaw slurry thiab nqus dej. Nws kuj txhim kho cement pob zeb compactness, txo cov matrix permeability, thiab boosts kuj tiv thaiv tsim corrosive brine. Peb tau txheeb xyuas nws kev sib raug zoo nrog feem ntau cov cementing additives, nrog rau cov dispersants, retarders thiab spacer fluids. Nws tseem muaj qhov ruaj khov ua npuas ncauj thaum lub sij hawm sib xyaw ua ke ntawm qhov chaw.

Tswv yim Ntawm -Ntawv qhia chaw rau FC-AG1L

Tsis txhob siv cov latex no los tiv thaiv -channeling tus neeg sawv cev nyob rau hauv downhole kub tshaj 150℃. Qhov kub thiab txias yuav ua rau cov latex demulsification, ua rau cov cement slurry tsis ruaj khov thiab tsis siv tau los tiv thaiv - roj av kev ua haujlwm. Peb feem ntau hais qhia ua ntej -lab kev ntsuas kev sib raug zoo thaum tsim dej tag nrho cov ntsev ntau tshaj 120,000 mg / L kom tsis txhob muaj kev pheej hmoo ntawm flocculation.

FC-AG02L: Nano Silicon Anti-Channeling Strengthening Additive rau Kub Kub & Tsawg Thaum Ntxov Lub Nkoj

Ntau lub qhov dej ntiav ntiav hauv ntug dej tawm tsam nrog kev txhim kho cov cement qeeb qeeb hauv qhov kub thiab txias, uas txuas ntxiv tos - ntawm - lub sijhawm cement thiab ncua kev ua haujlwm tom qab drilling. Peb cov cement ntxiv dag zog ntxiv FC-AG02L daws qhov mob no zoo kawg nkaus nrog nano silicon suspension mis, txhawb kev ua haujlwm ruaj khov hauv qab BHCT txog 230℃.

Cov khoom ua kua mis dawb no tsis yog - lom thiab tsis muaj ntxhiab nrog cov tshuaj lom neeg ua haujlwm siab. Tom qab tau muab sib xyaw rau hauv cov cement slurry system, cov khoom siv nano silicon hnov ​​​​mob nrog cov khoom siv cement hydration los ua cov khoom siv ntom ntom silicate gel, sau cov voids hauv cov cement pob zeb. Meanwhile, nws shortens lub gel hloov lub sij hawm sharply, tswj zoo hydrostatic kem siab los thaiv cov roj invasion txoj hauv paus.

Sib txawv ntawm latex anti-channeling agents txwv los ntawm qhov kub thiab txias, FC-AG02L ua haujlwm zoo nyob rau hauv ob qho tib si qis- qhov kub thiab txias qhov dej thiab ultra- qhov tob siab - cov pa roj reservoirs. Cov ntaub ntawv hauv chaw soj nstuam qhia tau hais tias nws tuaj yeem txhim kho 48- teev ntxov compressive zog ntau dua 60% hauv qab 15℃ambient mob, ua rau lub sijhawm kaw zoo heev.

Ib qho ntawm peb cov neeg ua haujlwm kev koom tes tau ntsib cov teeb meem tsis tu ncua ntawm cov roj av hauv lawv qhov dej sib sib zog nqus nrog BHCT txij li 205℃txog 220 degree. Tom qab hloov cov tshuaj latex los tiv thaiv-channeling additive nrog FC-AG02L, tsis muaj qhov ntsuas qhov ntsuas siab tau pom tom qab kev kho cov cement. Qhov qis- qhov kub thiab txias thaum ntxov kuj tau pab tus neeg siv txiav 36 teev ntawm tos- ntawm- lub sijhawm cement rau txhua qhov dej, ua kom pom tseeb cov nqi txuag ntawm kev pabcuam drilling.
