Hydroxyethyl Cellulose (HEC) bakeng sa mokelikeli oa ho cheka

Tikolohong e hlokang boiteko ba ho hlahloba oli le khase, bokgoni le botsitso ba maro a ho tjheka ke tsa bohlokwa haholo. Hydroxyethyl Cellulose (HEC), polymer e seng ya ionic, e qhibilihang ka metsing e tswang ho cellulose, e hlahile e le sehlomathiso sa bohlokwa mefuteng ya maro a ho tjheka. Dibopeho tsa yona tse ikgethang di ntlafatsa taolo ya viscosity, di ntlafatsa botsitso ba maro, mme di kenya letsoho tshebetsong e sireletsang tikoloho, e leng se etsang hore e be karolo ya bohlokwa mekgweng ya sejwalejwale ya ho tjheka.

Karolo ea HEC ho Ntlafatsong ea Mokelikeli oa ho Cheka

1. Taolo ea Viscosity le Phetoho ea Rheology

HEC e sebetsa e le mofetoleli ea rheology e sebetsang hantle, e kenyang boitšoaro ba pseudoplastic ho maro a ho tjheka. Sena se bolela hore viscosity ea mokelikeli e fokotseha ka sekhahla se ntseng se eketseha sa ho tjheka, e leng se nolofalletsang ho pompa habonolo ha ka nako e ts'oanang ho boloka viscosity e lekaneng ka sekhahla se tlase sa ho tjheka ho emisa le ho tsamaisa li-drill cuttings ho ea holimo. Thepa ena ea ho tjheka e ntlafatsa bokhoni ba ho tjheka le ho hloekisa li-wellboord.

2. Phokotso ea Tahlehelo ea Mokelikeli

E 'ngoe ea liphephetso tsa bohlokoa ts'ebetsong ea ho cheka ke ho fokotsa tahlehelo ea mokelikeli libakeng tse potolohileng. HEC e sebetsana le sena ka ho etsa kuku e tšesaane, e tiileng ea sefe maboteng a liliba, e fokotsa ho kenella ha mokelikeli ka katleho le ho boloka botsitso ba liliba. Thibelo ena ha e boloke feela botšepehi ba letamo empa hape e ntlafatsa ho hlaphoheloa ha hydrocarbon.

3. Ho tsitsa ha mocheso le letsoai

Mesebetsi ea ho tjheka hangata e kopana le libaka tse nang le mocheso o phahameng le letsoai le phahameng. HEC e bontša botsitso bo botle ba mocheso, e boloka ho teteana ha eona le thepa ea eona ea ts'ebetso esita le mochesong o phahameng. Ho feta moo, tlhaho ea eona e seng ea ionic e netefatsa hore e lumellana le maemo a letsoai, e thibela pula kapa ho senyeha ha letsoai le le teng.

4. Ho tlotsa ho Ntlafalitsoeng

HEC e ntlafatsa thepa ea ho tlotsa ea maro a ho phunya, e fokotsa khohlano pakeng tsa khoele ea ho phunya le seliba. Phokotso ena ea torque le ho hula e fokotsa ho tsofala ha lisebelisoa tsa ho phunya, e fokotsa kotsi ea liketsahalo tsa liphaephe tse khomaretsoeng, 'me e ntlafatsa ts'ebetso ea ho phunya ka kakaretso, haholo-holo lilibeng tse shebaneng le tse otlolohileng.

5. Ho Tsamaellana le Tikoloho

E nkiloe mehloling ea tlhaho ea cellulose, HEC e bola habonolo ebile e mosa tikolohong. Tšebeliso ea eona maro a ho cheka e tsamaisana le melaoana ea tikoloho le lipheo tsa botsitso, e fokotsang tšusumetso ea tikoloho ea ts'ebetso ea ho cheka.

Hydroxyethyl Cellulose (HEC) e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea maro a ho tjheka. Bokhoni ba eona ba ho laola ho teteana, ho fokotsa tahlehelo ea mokelikeli, ho mamella maemo a thata, le ho ntlafatsa ho tlotsa ho etsa hore e be tlatsetso ea bohlokoa mesebetsing ea sejoale-joale ea ho tjheka. Ka ho kenyelletsa HEC mefuteng ea maro a ho tjheka, basebetsi ba ka fihlela katleho e kholo, ba fokotsa likotsi tsa ts'ebetso, 'me ba khomarela maemo a tikoloho.
