Roj drilling qib HEC

Roj drilling qibHEC Hydroxyethyl celluloseyog ib hom nonionic soluble cellulose ether, soluble nyob rau hauv ob qho tib si dej kub thiab txias, nrog thickening, ncua kev kawm ntawv, adhesion, emulsification, zaj duab xis tsim, dej tuav thiab tiv thaiv colloid zog. Dav siv nyob rau hauv cov xim, tshuaj pleev ib ce, roj drilling thiab lwm yam industries.Oil drilling qib HECyog siv los ua thickener nyob rau hauv ntau yam av nkos xav tau rau drilling, zoo chaw, cementing thiab fracturing ua hauj lwm kom ua tau zoo fluidity thiab stability. Kev txhim kho av nkos thaum lub sij hawm drilling thiab tiv thaiv cov dej ntau los ntawm kev nkag mus rau hauv lub reservoir stabilize lub peev xwm ntawm cov reservoir.

Cov khoom ntawm hydroxyethyl cellulose

Raws li non-ionic surfactant, hydroxyethyl cellulose muaj cov khoom nram qab no ntxiv rau cov thickening, ncua kev kawm ntawv, kev sib txuas, ntab, zaj duab xis tsim, dispersing, dej tuav thiab muab kev tiv thaiv colloid:

1, HEC tuaj yeem yaj hauv dej kub lossis dej txias, qhov kub thiab txias tsis tuaj yeem ua rau dej nag, kom nws muaj ntau yam solubility thiab viscosity, thiab tsis yog thermal gel;

2, nws cov non-ionic tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants, ntsev, yog ib qho zoo heev colloidal thickener uas muaj siab concentration ntawm electrolyte kua;

3, dej tuav lub peev xwm yog ob zaug siab dua methyl cellulose, nrog zoo txaus adjustability,

4, HEC dispersion muaj peev xwm piv nrog methyl cellulose thiab hydroxypropyl methyl cellulose dispersion muaj peev xwm tsis zoo, tab sis muaj peev xwm tiv thaiv colloid muaj zog.

Plaub, hydroxyethyl cellulose siv: feem ntau yog siv los ua thickening tus neeg saib xyuas, tiv thaiv tus neeg sawv cev, nplaum, stabilizer thiab kev npaj ntawm emulsion, jelly, tshuaj pleev, tshuaj pleev ib ce, tshuaj ntxuav qhov muag, suppository thiab ntsiav tshuaj additives, kuj siv raws li hydrophilic gel, skeleton khoom, npaj pob txha. hom sustained tso tawm kev npaj, kuj tuaj yeem siv rau hauv cov zaub mov ua stabilizer thiab lwm yam haujlwm.

Cov khoom tseem ceeb hauv roj drilling

HEC yog nkig hauv kev ua tiav thiab cov av nkos. Nws pab muab cov av khib nyiab zoo thiab txo qis kev puas tsuaj rau lub qhov dej. Cov av nkos thickened nrog HEC yog yooj yim degraded rau hydrocarbons los ntawm acids, enzymes, los yog oxidants thiab yuav rov qab tau cov roj tsawg.

HEC tuaj yeem nqa av nkos thiab xuab zeb hauv cov av nkos tawg. Cov kua dej no tuaj yeem yooj yim degraded los ntawm cov kua qaub, enzymes lossis oxidants.

HEC muab cov dej zoo tshaj plaws uas tsis muaj cov khoom siv drilling uas muab cov permeability ntau dua thiab zoo dua drilling stability. Nws cov khoom ntim cov kua dej tuaj yeem siv rau hauv cov pob zeb nyuaj, nrog rau caving lossis zawv zawg shale formations.

Hauv kev ua haujlwm cementing, HEC txo cov kev sib txhuam hauv qhov pore-siab cement slurries, yog li txo cov qauv kev puas tsuaj los ntawm dej poob.

Tshuaj Specification

Cov khoom Qib 

Cov yam ntxwv ua haujlwm

1.Ntsev tsis kam

HEC ruaj khov nyob rau hauv cov tshuaj ntsev ntsev ntau heev thiab tsis decompose rau hauv ionic xeev. Siv hauv electroplating, tuaj yeem ua rau lub plating nto tiav, ci dua. Qhov tseem ceeb tshaj yog siv rau cov borate, silicate thiab carbonate latex xim, tseem muaj viscosity zoo heev.

2.Thickening khoom

HEC yog cov thickener zoo tagnrho rau coatings thiab tshuaj pleev ib ce. Hauv kev siv tswv yim, nws thickening thiab ncua kev kawm ntawv, kev nyab xeeb, dispersion, dej tuav ua ke daim ntawv thov yuav tsim ib tug zoo tagnrho cov nyhuv.

3. Pseudoplastic

Pseudoplasticity yog cov cuab yeej uas cov viscosity ntawm cov tshuaj txo nrog qhov nce ntawm kev sib hloov ceev. HEC muaj cov xim latex yog ib qho yooj yim rau siv nrog txhuam los yog cov menyuam thiab tuaj yeem ua kom lub ntsej muag du, uas tuaj yeem ua rau kev ua haujlwm zoo; Hec-muaj tshuaj zawv plaub hau yog kua thiab nplaum, yooj yim diluted thiab yooj yim dispersed.

4.Kev tuav dej

HEC pab kom cov dej noo ntawm lub cev nyob rau hauv lub xeev zoo tagnrho. Vim tias ib qho me me ntawm HEC hauv cov kua dej tuaj yeem ua tiav cov dej tuav tau zoo, kom lub kaw lus txo cov dej xav tau thaum lub sijhawm npaj. Yog tsis muaj dej tuav thiab adhesion, cement mortar yuav txo nws lub zog thiab adhesion, thiab av nplaum kuj yuav txo tau cov yas nyob rau hauv tej yam kev nyuaj siab.

5.Membrane

Lub membrane tsim cov khoom ntawm HEC tuaj yeem siv rau hauv ntau qhov kev lag luam. Hauv kev ua haujlwm ntawm papermaking, coated nrog HEC glazing tus neeg sawv cev, tuaj yeem tiv thaiv cov roj nkag mus, thiab tuaj yeem siv los npaj lwm yam ntawm cov tshuaj papermaking; HEC nce elasticity ntawm fibers thaum lub sij hawm weaving txheej txheem thiab yog li txo cov neeg kho tshuab kev puas tsuaj rau lawv. HEC ua raws li cov yeeb yaj kiab tiv thaiv ib ntus thaum sizing thiab dyeing ntawm cov ntaub thiab tuaj yeem ntxuav tawm ntawm cov ntaub nrog dej thaum tsis xav tau kev tiv thaiv.

Daim ntawv qhia rau oilfield kev lag luam:

Siv nyob rau hauv roj teb cementing thiab drilling

●Hydroxyethyl cellulose HEC tuaj yeem siv los ua cov thickener thiab cementing tus neeg sawv cev rau cov kua dej zoo. Ib qho kev daws teeb meem qis uas pab ua kom pom tseeb, yog li txo qis kev puas tsuaj rau lub qhov dej. Cov kua dej thickened nrog hydroxyethyl cellulose yog yooj yim tawg los ntawm acids, enzymes los yog oxidants, zoo heev txhim kho lub peev xwm rov qab hydrocarbons.

●Hydroxyethyl cellulose HEC yog siv los ua cov khoom thauj hauv cov kua dej zoo. Cov kua dej no tseem tuaj yeem tawg tau yooj yim los ntawm cov txheej txheem tau piav qhia saum toj no.

●Drilling kua nrog hydroxyethyl cellulose HEC yog siv los txhim kho drilling stability vim nws cov ntsiab lus tsis tshua muaj khib nyiab. Cov kev ua tau zoo suppressor kua yuav siv tau rau drilling nruab nrab rau siab hardness pob zeb txheej thiab hnyav shale los yog av nkos shale.

●Hauv kev ua haujlwm cement, hydroxyethyl cellulose HEC txo cov kev sib txhuam ntawm cov av nkos thiab txo cov dej los ntawm cov pob zeb poob.
