Hydroxyethyl Cellulose (HEC) i polymer inonyungudika nemvura inoshandiswa zvakanyanya mukuchera mafuta. Yayo yakasarudzika yemuviri uye makemikari zvimiro zvinoipa akawanda mabhenefiti mundima iyi.
1. Kuvandudza rheological properties
Hydroxyethyl cellulose ine yakanaka thickening zvivakwa uye inogona zvakanyanya kuwedzera viscosity yemvura yekuchera. Iyi pfuma inonyanya kukosha panguva yekuchera, sezvo high-viscosity drilling fluids inogona kumisa zviri nani kucheka kwekucheka uye kudzivirira kuti isaisa pasi pegomba kana pamadziro epombi, nekudaro ichivandudza kuchera uye kuchengeteka. Iyo pseudoplastic maitiro eHEC mhinduro inoguma yakaderera viscosity pakakwirira shear rates (senge padyo ne drill bit), iyo inoderedza friction uye kupomba simba, uye yakakwira viscosity pa low shear rates (senge padhuze nemadziro etsime), iyo inobatsira Pakutakura uye kumisa zvibooreso cuttings.
2. Hydration uye mvura yekuchengetedza zvinhu
Hydroxyethyl cellulose ine yakanakisa hydration zvivakwa uye inogona kukurumidza kunyungudika mumvura uye kugadzira yunifomu mhinduro. Kuita uku kunogonesa kukurumidza kugadzirira uye kugadzirisa kwekuchera magadzirirwo emvura pane saiti, kuwedzera kushanda kuchinjika. Mukuwedzera, HEC inewo simba rekuchengetedza mvura, iyo inogona kuderedza kubuda uye kurasikirwa kwemvura mumvura yekuchera uye kuchengetedza kugadzikana uye kushanda kwemvura yekuchera. Kunyanya mukupisa kwepamusoro uye kudzvinyirirwa kwepamusoro, nzvimbo dzayo dzekuchengetedza mvura dzinonyanya kukosha.
3. Sefa control
Panguva yekuchera, kurasikirwa kwemvura yemvura yekuchera chinhu chakakosha parameter. Kurasikirwa kwakanyanya kwefiltration kuchaita kuti kuwedzera kwedhaka keke ukobvu, izvo zvinozotungamira kumatambudziko akadai sekusagadzikana kwemadziro uye kubuda zvakanaka. Hydroxyethyl cellulose inogona kunyatso kudzikisa kurasikirwa kwemvura yemvura yekuchera, kugadzira dense sefa keke, kuderedza njodzi yekudonha uye kudonha kwemadziro etsime, uye kugadzirisa kugadzikana kwemadziro etsime. Uye zvakare, HEC inogona kuchengetedza kuita kwakadzikama pasi pezvakasiyana pH kukosha uye electrolyte yekumisikidza mamiriro uye kuchinjika kune akasiyana akaoma mamiriro e geological.
4. Eco-friendly
Sezvo mitemo yezvakatipoteredza ichiwedzera kuomesera, kudiwa kwemvura yekuchera ine hushamwari kwezvakatipoteredza kuri kuwedzerawo. Seyakasikwa cellulose inobuda, hydroxyethyl cellulose ine yakanaka biodegradability uye ine zvishoma kukanganisa nharaunda. Kuenzaniswa nemamwe mapolymer ekugadzira, kushandiswa kweHEC kunoderedza kusvibiswa kunokuvadza uye kunobatsira kuzadzisa zvinangwa zvekuchera zvakasvibirira. Uye zvakare, iyo isiri-chepfu uye isingakuvadzi chimiro cheHEC zvakare inoderedza njodzi dzinogona kuitika kune anoshanda hutano.
5. Zveupfumi
Kunyangwe mutengo wehydroxyethyl cellulose wakakwirisa, kuita kwayo kwakanaka panguva yekushandiswa kunogona kuderedza zvakanyanya mutengo wese panguva yekuchera. Chekutanga, HEC's inobudirira kukora uye kuchengetedza mvura inoderedza huwandu hwemvura yekuchera uye mari yezvinhu. Chechipiri, kugadzikana uye kuvimbika kweHEC kunoderedza njodzi yekukundikana kwepasi uye kuvhara kusina kurongwa, kuderedza kuchengetedza nekugadzirisa mari. Chekupedzisira, HEC's ine hushamwari zvivakwa zvinoderedza mari inoshandiswa pakurasa marara uye kutevedzera kwezvakatipoteredza.
6. Kugarisana uye zvakasiyana-siyana
Hydroxyethyl cellulose ine kugadzikana kwakanaka kwemakemikari uye kuenderana kwakakura, uye inogona kuenderana nemhando dzakasiyana dzekuwedzera uye yekuchera mvura masisitimu kuti iite inoumbwa system ine chaiwo mabasa. Semuenzaniso, HEC inogona kushandiswa pamwe chete neanorwisa-kudonha maajenti, anti-leak agents uye mafuta ekuzora kuvandudza kushanda kwakakwana kwemvura yekuchera uye kusangana nemamiriro akasiyana e geological uye zvinodiwa pakuchera. Mukuwedzera, HEC inogonawo kushandiswa mune mamwe makemikari emumunda wemafuta akadai semvura yekupedzisa uye fracturing fluid, ichiratidza kushandiswa kwayo kwakasiyana-siyana.
Hydroxyethyl cellulose ine mabhenefiti akakosha mukuchera oiri, inonyanya kuratidzwa mukuvandudza rheological zvivakwa, kuwedzera hydration uye kuchengetedza kwemvura kugona, kudzora zvinobudirira vhoriyamu yekusefa, kuve nehushamwari kwezvakatipoteredza, hupfumi uye multifunctional. Aya mabhenefiti anoita HEC chinhu chakakosha uye chakakosha chekuwedzera mukuchera oiri maitiro, zvichibatsira kuita mabasa ekuchera anobudirira, akachengeteka uye ane hushamwari. Nekuenderera mberi kwekufambira mberi kwehunyanzvi uye nekudzika kwekushandisa, tarisiro yekushandiswa kwehydroxyethyl cellulose mukuchera oiri ichave yakakura.
