Chav ntsuas kub ntsev-Resistant Fluid Poob Control Starch yog ib qho tshwm sim ntawm polymer drilling kua additive tsim los ntawm kev hloov kho tshuaj tshwj xeeb. Tsom ntsoov rau hauv chav ua haujlwm kub thiab khav theeb zoo ntsev ua haujlwm, cov khoom no yog tsim los ntawm siab -cov hmoov txhuv nplej siab zoo. Los ntawm kev qhia cov pab pawg ua haujlwm xws li carboxymethyl thiab hydroxyl txhawm rau txhim kho nws cov qauv molecular, nws kov yeej cov kev txwv ntawm cov hmoov txhuv nplej siab, xws li cov dej tsis zoo solubility thiab tsis muaj ntsev tsis muaj zog. Tshwj xeeb tsim los rau kev ua haujlwm drilling hauv ntau cov dej ntsev tsim nyob rau hauv chav tsev kub (0-60 degree), nws tuaj yeem txo cov av nkos poob thiab ua kom muaj kev ruaj ntseg zoo nyob rau hauv chav tsev kub qhov chaw drilling. Raws li cov khoom siv muaj txiaj ntsig zoo uas sib npaug ntawm cov dej tsis zoo tswj kev ua haujlwm, ntsev tsis kam thiab cov txiaj ntsig ib puag ncig, nws tau siv dav hauv cov dej num hauv cov dej hauv chav tsev kub, nrog rau cov roj thiab roj drilling, geological tshawb nrhiav drilling thiab lwm yam kev lag luam, muab kev txhawb nqa zoo rau kev ruaj ntseg zoo thiab kev tiv thaiv reservoir.
Core Product Features
Chav zoo heev kub ntsev tiv taus, haum rau complex saline formations
Ua kom haum rau chav ua haujlwm kub thiab muaj cov ntsev ua haujlwm zoo, cov khoom lag luam muaj kev ua siab ntev rau cov ntsev ions tom qab hloov cov qauv molecular. Nws tuaj yeem ua haujlwm ruaj khov hauv dej tshiab, dej hiav txwv, dej qab ntsev thiab cov dej qab ntsev cov av nkos, tsis cuam tshuam los ntawm ntsev concentration. Nws tuaj yeem tiv thaiv kev yaig ntawm inorganic ntsev xws li NaCl thiab CaCl₂ hauv kev tsim, zam qhov txo qis ntawm cov kua dej tswj kev ua tau zoo los ntawm kev cuam tshuam ntsev ion, thiab daws cov teeb meem ntawm cov hmoov txhuv nplej siab, xws li kev ua tsis tau yooj yim thiab cov kua dej ntau dhau hauv cov ntsev ntsev. Nws yog qhov tsim nyog rau ntau yam hauv chav tsev kub saline drilling scenarios, suav nrog offshore drilling thiab ntsev -gypsum txheej drilling, ua tau raws li cov kev xav tau ntawm cov dej drilling hauv cov dej hauv chav tsev kub.
Ua kom muaj kuab paug tswj kev ua haujlwm kom muaj kev ruaj ntseg zoo
Cov khoom nthuav tawm cov dej tsis zoo tswj cov nyhuv ntawm chav tsev kub. Nyob rau hauv chav tsev kub drilling ib puag ncig, nws tuaj yeem yaj sai sai thiab tawg mus rau hauv cov kua dej drilling. Through molecular adsorption and cross-linking, it forms a thin, dense and tough filter cake on the wellbore surface, effectively reducing mud fluid loss, controlling the filtration of drilling fluid liquid phase into the formation, and reducing the damage to oil and gas reservoirs caused by filtrate intrusion. Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam shale o thiab dispersion, tiv thaiv kev sib tsoo xws li kev sib tsoo ntawm lub qhov dej thiab txoj kab uas hla, ua kom muaj kev ruaj ntseg zoo, txo qhov tshwm sim ntawm cov teeb meem xws li kev sib tw siab torque thiab tripping swabbing, thiab xyuas kom muaj kev vam meej thiab ua tau zoo ntawm cov phiaj xwm drilling nyob rau hauv chav tsev kub geological tej yam kev mob.
Yooj yim yoog raws, cuam tshuam tsawg kawg nkaus ntawm Drilling Fluid Rheology
Cov khoom muaj zog heev compatibility. Raws li cov khoom siv tsis yog - ionic polymer, nws tsis tshua ua rau lub cev viscosity los yog hloov cov rheology qub tom qab ntxiv rau cov kua dej drilling, thiab tuaj yeem siv ncaj qha yam tsis muaj kev hloov kho ntxiv ntawm cov kua dej drilling, ua haujlwm yooj yim. Lub caij no, nws muaj kev sib raug zoo nrog lwm cov khoom siv ntxiv hauv cov kua dej drilling, xws li polymers, cross- txuas cov tshuaj thiab cov kab mob. Nws tuaj yeem ua kom zoo dua qhov kev ua tau zoo ntawm cov dej drilling thiab ntxiv txhim kho chav dej kub tsis zoo tswj, ua tau raws li kev xav tau ntawm cov dej sib txawv thiab cov tshuab drilling hauv cov dej hauv cov dej hauv cov dej hauv cov dej hauv chav dej, thiab zam kev ua haujlwm txawv txav los ntawm kev tsis sib haum xeeb ntxiv.
Environmentally Friendly nrog Controllable Nqi
Ua los ntawm cov hmoov txhuv nplej siab ntuj, cov khoom lag luam muaj biodegradability zoo thiab yuav tsis ua qias neeg tsim, dej hauv av thiab ib puag ncig ib puag ncig, ua raws li kev tiv thaiv ib puag ncig ntawm kev loj hlob ntsuab oilfield thiab tsim nyog rau kev ua haujlwm drilling hauv thaj chaw rhiab heev. Piv nrog rau cov khoom siv hluav taws xob hluav taws xob tswj cov dej tsis zoo, nws muaj cov khoom siv dav dav thiab cov nqi tsim khoom tsawg, thiab yuav tsum tau siv me me (kev pom zoo yog 0.3-0.5% hauv cov dej tshiab drilling dej thiab 1-1.5% hauv dej ntsev ntsev dej), uas tuaj yeem txo cov nqi tshuaj lom neeg ntawm kev lag luam drilling thiab ua tiav ob qho txiaj ntsig kev lag luam.
Ua ke nrog nws cov yam ntxwv tseem ceeb, cov khoom lag luam feem ntau yog tsim rau ntau yam dej -raws li drilling kua tshuab nyob rau hauv chav tsev kub (0-60℃). Nws yog feem ntau yoog rau hauv chav ua haujlwm kub, nrog rau chav tsev kub tsis zoo ntawm cov kua dej tsis zoo thiab muaj zog sib xws, thiab tau siv dav hauv cov haujlwm drilling nyob rau hauv chav tsev kub geological, suav nrog:
- Roj thiab roj drilling kev ua haujlwm, tshwj xeeb tshaj yog tsim nyog rau kev ua haujlwm nyuaj xws li kev tsim cov dej qab ntsev, dej hiav txwv drilling thiab ntsev -gypsum txheej drilling;
- Geological tshawb nrhiav drilling, hydrological zoo drilling thiab lwm qhov chaw, uas tuaj yeem tswj tau cov dej tsis zoo thiab tiv thaiv cov dej hauv av.
Khoom Mechanism ntawm Action
Chav ntsuas kub ntsev-Resistant Fluid Poob Control Starch ua tiav ob qho kev tiv thaiv ntawm cov kua dej tsis zoo tswj thiab ntsev tiv thaiv los ntawm "adsorption- thaiv-} kev ruaj khov" triple nyhuv: Ua ntej, cov pab pawg ua haujlwm ntawm cov hmoov txhuv nplej siab hloov pauv tuaj yeem tsim electrostatic adsorption nrog cov av nplaum ntawm cov khoom siv hauv av, txo cov khoom siv hauv av. thaj chaw tshwj xeeb thiab tus nqi tsis zoo, inhibit av nplaum hydration thiab dispersion, thiab stabilize lub drilling kua system. Second, the molecular chains form a three-dimensional network structure through cross-linking, blocking the pores of the drilling fluid, reducing liquid phase penetration, and forming a dense filter cake on the wellbore to further block filtrate intrusion. Thib peb, kev taw qhia ntawm cov pab pawg ua haujlwm txhim kho cov ntsev tsis kam ntawm cov saw hlau molecular, uas tuaj yeem tswj cov qauv kev ruaj ntseg hauv siab - ntsev ib puag ncig, zam kev ua haujlwm tsis ua haujlwm los ntawm kev puas tsuaj los ntawm ntsev ion, thiab xyuas kom muaj kev ruaj ntseg ntawm cov kua dej tsis tu ncua.
