Hydroxethyl celdlosese (Hec) ke e tloaelehileng indastering ea oli ea oli, moo e sebeletsang mesebetsi e fapaneng ea ho cheka liforomo tsa metsi. Mekhoa ena, hape e tsejoang ka hore e cheke semumu, re bapale karolo ea bohlokoa ka ho phallela mokhoa oa ho cheka le ho fafatsa sehiloeng ka holim'a seliba. Mona ke kakaretso ea lits'ebetso, lits'ebetso le litebiso tsa maqheka a ho cheka ha oli:

1. Selelekela ho hydroxeeyyl cellulosese (Hec) ka ho cheka oli

1.1 Tlhaloso le mohloli

Hydroxethyl cellulosese ke selefou e sentsoeng e fumanoeng ka ponts'o ea selefounu. Ho etsoa hangata ho tloha pulp ea lehong kapa k'hothone 'me e sebetsoa ho etsa moemeli ea qhibilihang ea metsi, a sheba moemeli ea bonang metsi.

1,2 moemeli ea shebang ho fofa ka metsi

Hec o sebelisoa ho ho cheka maro a hoele ho tloaela le ho laola pono ea bona. Sena se bohlokoa bakeng sa ho boloka khatello e hlokahalang ea hydrauli ka hantle le ho netefatsa li-cuttings tse phethahetseng li tsamaisana.

2. Mesebetsi ea hydroxethyl celluloulose ea metsi a entsoeng ka oli

2.1 taolo ea li-viscosity

Hec o sebetsa e le mosebeletsi oa Rheology Morifier, ea fanang ka taolo holim'a pono ea mokelikeli o tahiloeng. Bokhoni ba ho fetola litšoantšiso ho bohlokoa bakeng sa ho ntlafatsa thepa ea phallo ea mokelikeli tlasa maemo a fapaneng a ho taka.

Li-cukets tse 2.2 ho emisoa

Tsamaisong e cheke, li-cuketings li hlahisoa, 'me ho bohlokoa ho emisa likepe tsena ho mokelikeli oa ona hantle. Hec o thusa ho boloka ho emisoa ha li-cuttings.

2.3 Ho hloekisa sekoti

Ho hlapaola ho hloeka ho bohlokoa bakeng sa ketsahalo e chesang. Hec o kenya letsoho bokhoni ba ho tsamaisa le ho tsamaisa ho bokella thepa ka sefitsoana ebe ba khothaletsa ts'ebetso e lekaneng ea ho cheka.

2.4 Ho tsitsase mocheso

Hec o bonts'a botsitso mocheso mocheso o motle, o etsa hore o boloke o sebedish marong a ka kopanyang mocheso o fapaneng nakong ea mocheso nakong ea mocheso nakong ea mocheso.

3. Litšitiso ho Maro a oli ea oli

3.1 Mefuta e thehiloeng Metsi

Li-Hec li sebelisoa ka maro a se nang metsi a thehiloeng metsing, a fana ka taolo ea lipono, li-cutlets li emise, le botsitso. E ntlafatsa ts'ebetso ea kakaretso ea li-muds tse thehiloeng metsing libakeng tse fapaneng tsa metsi.

3.2 Shale Sihires

Hec e ka kenya letsoho ho Shale inhibition ka ho theha tšitiso e sireletsang marakong a maholohali. Sena se thusa ho thibela ho ruruha le ho se fetohe ha mofuta oa moriti, ho boloka botsitso hantle.

3.3 Sethala sa ho potoloha

Ts'ebetsong ea ho cheka moo ho lahleheloang ke ho thehoa, maqhe a ka kenyelletsoa ho thusa ho laola, ho tiisa hore metsi a ho cheka a lula a le hantle seliba.

4. LITLHAKISO LE LITLHAKISO

4.1 TLHOKOMELISO

Khatello ea Hec ho Maraba a Chesang ho Akarelletsa ho Sebetsa Ka Hloko Ho fihlela thepa e batlang e le e sa lebelloang kapa e mpefatsang hampe e le ho baka litšobotsi tse ling tsa mokelikeli.

4.2 Khokahano

Ho tsamaisana le litlatsetso tse ling tsa mokelikeli le likarolo tse ling tsa bohlokoa. Ho nahanisisa ka hloko ho lokela ho fuoa mokhoa oa ho etsa o thibelang litaba tse kang ho shapuoa kapa ho fokotsoa.

4.3 Taolo ea Frieid

Ha hec a ka kenya letsoho taolong ea ho lahleheloa ke metsi, litlatsetso tse ling le tsona li kanna tsa hlokahala ho sebetsana le mathata a itseng a ho lahleheloa ke metsi le ho laola li-svindara.

5. Q QALANG

Hydroxethyl Celluloseses e bapala karolo ea bohlokoa ho ts'ebetso ea oli ea oli ka ho kenya letsoho ka katleho le botsitso ba metsi a ho nooang le ho tsitsipana a metsi a hoele. Joaloka Moemeli ea nkang Boemo, o thusa ho laola thepa ea koae, e emisa ho itšepa le ho boloka botsitso hantle. Mafuputsi a hloka ho nahana ka hloko le ho tsepamisa mohopolo, katinati ea eona le tšebeliso ea tsona ka kakaretso ho etsa bonnete ba hore li-hec li bolela melemo ea eona likopo tse cheleng tsa oli.
