Hydroxyethyl cellulose (HEC) chinhu chinowanzo shandiswa muindasitiri yekuchera mafuta, uko chinoshanda mabasa akasiyana-siyana mukugadzira mvura yekuchera. Mafomu aya, anozivikanwawo semadhaka ekuchera, anoita basa rakakosha mukuita kuti kuchera kuitwe nekutonhodza nekuisa mafuta pagomba rekuchera, kutakura zvidimbu pamusoro, uye kupa kugadzikana kwegomba remvura. Heino pfupiso yekushandiswa, mabasa, uye kufunga nezveHEC mukuchera mafuta:

1. Nhanganyaya yeHydroxyethyl Cellulose (HEC) muKuchera Oiri

1.1 Tsanangudzo uye Manyuko

Hydroxyethyl cellulose ipolymer yakagadziriswa ye cellulose inowanikwa nekubatanidza cellulose ne ethylene oxide. Inowanzo torwa kubva mu pulp yehuni kana donje uye inogadziriswa kugadzira chinhu chinonyunguduka mumvura, chinosimbisa ganda.

1.2 Mumiriri weViscosifying muDrilling Fluids

HEC inoshandiswa mukuchera mvura kuti igadzirise uye idzore kusviba kwayo. Izvi zvakakosha pakuchengetedza kumanikidzwa kwe hydraulic mugomba remvura uye kuona kuti zvidimbu zvinofamba zvakanaka pamusoro.

2. Mashandiro eHydroxyethyl Cellulose muOiri Drilling Fluids

2.1 Kudzora Kusviba

HEC inoshanda senzira yekugadzirisa rheology, ichipa simba pamusoro pekupenya kwemvura inoboorwa. Kugona kugadzirisa kupenya kwakakosha pakuvandudza hunhu hwemvura inoboorwa mumamiriro akasiyana ekuboorwa.

2.2 Kuchekwa Kwesimbi

Mukuita kwekuchera, matombo anochekwa anogadzirwa, uye zvakakosha kumisa zvidimbu izvi mumvura yekuchera kuti zvive nyore kubvisa kubva mugomba. HEC inobatsira kuchengetedza kumiswa kwakasimba kwezvidimbu.

2.3 Kuchenesa Maburi

Kuchenesa maburi zvakanaka kwakakosha pakuita basa rekuchera. HEC inobatsira kuti mvura ikwanise kutakura nekutakura zvidimbu pamusoro, zvichidzivirira kuungana mugomba remvura uye zvichikurudzira mashandiro ekuchera zvakanaka.

2.4 Kugadzikana kweTembiricha

HEC inoratidza kugadzikana kwakanaka kwekushisa, zvichiita kuti ikodzere kushandiswa muzvinwiwa zvekuboorera zvinogona kusangana nekupisa kwakasiyana-siyana panguva yekuboorera.

3. Mashandisirwo muOiri Drilling Fluids

3.1 Mvura Inocherwa Nemvura

HEC inowanzoshandiswa muzvinwiwa zvinocherwa nemvura, ichipa kudzora kusviba, kumisa kucheka, uye kugadzikana. Inowedzera kushanda kwese kwematope akavakirwa mumvura munzvimbo dzakasiyana-siyana dzekucherwa.

3.2 Kudzivisa Shale

HEC inogona kubatsira mukudzivirira shale nekugadzira chipingamupinyi chinodzivirira pamadziro etsime. Izvi zvinobatsira kudzivirira kuzvimba nekuputsika kwemafuro, zvichiita kuti tsime rirambe rakagadzikana.

3.3 Kudzora Kuyerera Kweropa Muropa

Mumabasa ekuboora uko kurasikirwa kwemvura pakuumbwa kwayo kuri dambudziko, HEC inogona kuiswa muchimiro ichi kubatsira kudzora kurasikirwa kwekufamba kwemvura, zvichiita kuti mvura yekuboora irambe iri mutsime.

4. Zvekufunga nezvazvo uye Zvekudzivirira

4.1 Kuisa pfungwa pachinhu chimwe chete

Kuwanda kweHEC muzvinwiwa zvinoboorwa kunofanirwa kudzorwa nokungwarira kuti zviwane hunhu hwe rheological hunodiwa pasina kukonzera kukora kwakanyanya kana kukanganisa zvimwe zvinhu zvemvura.

4.2 Kuenderana

Kuenderana nezvimwe zvinhu zvinowedzerwa mumvura yekuboora kwakakosha. Kunyatsofunga nezvemushonga wese kunofanirwa kupihwa kudzivirira matambudziko akadai sekupwanyika kana kudzikira kwekushanda kwawo.

4.3 Kudzora Kusefa Kwemvura

Kunyange zvazvo HEC ichigona kubatsira mukuderedza kurasikirwa kwemvura, zvimwe zvinowedzera zvinogonawo kudiwa kugadzirisa matambudziko chaiwo ekurasikirwa kwemvura uye kuchengetedza kudzora kusefa.

5. Mhedziso

Hydroxyethyl cellulose inoita basa rakakosha mukuchera mafuta nekubatsira mukushanda zvakanaka uye kugadzikana kwemvura inocherwa. Semushonga unosimbisa ganda, unobatsira kudzora hunhu hwemvura, kumisa kucheka, uye kuchengetedza kugadzikana kwenzvimbo dzakachekwa. Vagadziri vemafuta vanofanirwa kunyatsoongorora huwandu, kuenderana, uye kugadzirwa kwese kwese kuti vave nechokwadi chekuti HEC inowedzera mabhenefiti ayo mukushandisa kuchera mafuta.
