Hydroxyethyl cellulose (HEC) chinhu chinowedzera muindasitiri yekuchera mafuta, kwainoshandira mabasa akasiyana mukudhirowa kwemvura. Maumbirwo aya, anozivikanwawo sekuchera madhaka, anoita basa rakakosha kufambisa basa rekuchera nekutonhodza nekuzora chibhorani, kutakura zvicherwa pamusoro, nekupa kugadzikana kutsime. Heino tarisiro yemashandisirwo, mabasa, uye kufunga kweHEC mukuchera oiri:

1. Nhanganyaya yeHydroxyethyl Cellulose (HEC) muOiri Drilling

1.1 Tsanangudzo uye Kwakabva

Hydroxyethyl cellulose imodified cellulose polymer inowanikwa nekuita cellulose ine ethylene oxide. Inowanzo kutorwa kubva muhuni pulp kana donje uye inogadziriswa kugadzira inonyungudika nemvura, viscosifying agent.

1.2 Viscosifying Agent muDrilling Fluids

HEC inoshandiswa mukuchera zvinwiwa kugadzirisa uye kutonga viscosity yavo. Izvi zvakakosha pakuchengetedza iyo inodiwa hydraulic pressure mutsime uye nekuona kuchekwa kwakanaka kutakurwa kuenda pamusoro.

2. Mabasa eHydroxyethyl Cellulose muOiri Drilling Fluids

2.1 Viscosity Control

HEC inoshanda se rheology modifier, ichipa kutonga pamusoro pe viscosity yemvura yekuchera. Iko kugona kugadzirisa viscosity kwakakosha pakugadzirisa kuyerera kweiyo fluid pasi pemamiriro akasiyana ekuchera.

2.2 Cuttings Kumiswa

Mukuita kuchera, kucheka kwematombo kunogadzirwa, uye zvakakosha kumisa kucheka uku mumvura yekuchera kuitira kuti kubviswa kwavo kubva mutsime. HEC inobatsira mukuchengetedza kumiswa kwakagadzikana kwekucheka.

2.3 Kuchenesa Gomba

Kunyatsochenesa gomba kwakakosha pakuchera. HEC inobatsira pakukwanisa kwemvura kutakura uye kutakura zvidimbu kusvika pamusoro, kudzivirira kuungana mutsime uye kukurudzira kushanda kwakanaka kwekuchera.

2.4 Kugadzikana kweTembiricha

HEC inoratidza kugadzikana kwakanaka kwekushisa, zvichiita kuti ive yakakodzera kushandiswa mukuchera zvinwiwa zvinogona kusangana nemhando yetembiricha panguva yekuchera.

3. Zvikumbiro muOiri Drilling Fluids

3.1 Mvura-Yakavakirwa Pakuchera Fluids

HEC inowanzoshandiswa mumvura-based drilling fluids, inopa viscosity control, cuttings kumiswa, uye kugadzikana. Inosimudzira kushanda kwese kwemvura-yakavakirwa madhaka munzvimbo dzakasiyana dzekuchera.

3.2 Shale Inhibition

HEC inogona kuita kuti shale inhibition nekugadzira chidziviriro chekudzivirira pamadziro etsime. Izvi zvinobatsira kudzivirira kuzvimba uye kuparara kwe shale formations, kuchengetedza wellbore kugadzikana.

3.3 Yakarasika Kutenderera Kudzora

Mumabasa ekuchera apo kurasikirwa kwemvura kune kuumbwa kunonetsa, HEC inogona kuiswa mukugadzirisa kubatsira kudzora kutenderera kwakarasika, kuve nechokwadi chokuti mvura yekuchera inoramba iri mutsime.

4. Kufunga uye Kungwarira

4.1 Kuisa pfungwa

Iko kusungirirwa kweHEC mumvura yekuchera kunoda kunyatsodzorwa kuti uwane inodiwa rheological zvimiro pasina kukonzera kukora zvakanyanya kana kukanganisa mamwe maitiro emvura.

4.2 Kugarisana

Kuenderana nezvimwe zvekuchera mvura yekuwedzera uye zvikamu zvakakosha. Kunyatsotariswa kunofanirwa kupihwa kune iyo yose dhizaini kudzivirira nyaya dzakaita senge flocculation kana kuderedzwa kushanda.

4.3 Fluid Filtration Control

Nepo HEC inogona kubatsira pakudzora kurasikirwa kwemvura, zvimwe zvinowedzera zvinogona zvakare kudikanwa kugadzirisa chaiyo yekurasikirwa kwemvura nyaya uye kuchengetedza filtration control.

5. Mhedziso

Hydroxyethyl cellulose inoita basa rakakosha mukuchera oiri nekubatsira mukubudirira uye kugadzikana kwemvura yekuchera. Semumiriri we viscosifying, inobatsira kudzora zvimisikidzo zvemvura, kumisa kucheka, uye kuchengetedza kugadzikana kwetsime. MaFormulators anofanirwa kutarisisa kutarisisa, kuenderana, uye kuumbwa kwese kuti ive nechokwadi chekuti HEC inowedzera mabhenefiti ayo mukuchera mafuta.
