Hydroxethyl Cellulose (HEC) inowanzowedzera muindasitiri yemafuta yekukweva, kwainobatira mabasa akasiyana siyana mukurovera mafiriro. Aya mafambiro, anozivikanwawo sematope anomisikidza, anotamba basa rakakosha mukufambisa maitiro nekutonhora uye nekucheka zvishoma, kutakura kucheka kumusoro, uye kupa kugadzikana kune tarisiro yebrick. Heino kutarisisa kwezvinhu zvinoshandiswa, mabasa, uye kufunga kwehisheni mukukweva kwemafuta:

1. Nhanganyaya kune hydroxytHyl Cellulose (Hec) mukukweva kwemafuta

1.1 Tsanangudzo uye Tsime

HydroxytHyl Cellulose ndeye yakagadziridzwa cellulose polymer inowanikwa nekuita cellulose ine ethylyone oxide. Izvo zvinowanzotorwa kubva kune huni durp kana machira uye anogadziriswa kuti agadzire iyo manyorerwo-soluble mumiriri.

1.2 viscondifying mumiririri mukukwevera mvura

Hec inoshandiswa mukukwezva mvura yekudhara kuti igadzirise uye kudzora viscosity yavo. Izvi zvinokoshesesa kuchengetedza izvo zvinodikanwa hydraulic kudzvinyirira muBellbore uye kunoita kuti cutings yakakodzera kutakura kumusoro.

2.

2.1 viscosity control

HEC inoita seRheology modifier, ichipa kutonga pamusoro peiyo visikopa yekukweva kwemvura. Iko kugona kwekugadzirisa viscosity kwakakosha kuti ugadzirise iyo inoyerera zvivakwa zvemvura pasi pemamiriro akasiyana ekukwevera pasi.

2,2 Kubvisa Kumiswa

Mukutonga kwekudhirowa, kucheka matombo kunogadzirwa, uye kwakakosha kumisa izvi cuttings mukukweva kwemvura kufambisa kubviswa kwavo kubva kuWellbore. Hec inobatsira mukuchengetedza kugadzikana kumiswa kwekucheka.

2.3 Hole Kuchenesa

Kuchenesa gomba rinobudirira kwakakosha pakukwezva maitiro. HEC inopa kune kugona kwemvura kutakura uye kutakura cuttings kune iyo nzvimbo, kudzivirira kuunganidzwa muTellbore uye kusimudzira kushanda kwakadzama.

2.4 Kupisa tembiricha

HEC inoratidza yakanaka tembiricha yekudziya, ichiita kuti iite kuti iwane kushandiswa mumvura inodhonzera iyo ingasangana nehuwandu hwekupisa panguva yekudhirowa.

3. Zvikumbiro mumafuta anokwezva mvura

3.1 mvura-yakavakirwa mvura yekukwevera mvura

HEC inowanzo shandiswa mumvura-yakavakirwa mvura yekukwevera mvura, kupa viscosity kudzora, kudzora kumiswa, uye kugadzikana. Iyo inosimudzira kuita kwese kwemadhaka-yakavakirwa mvura mumadhadha akasiyana siyana ekudhira.

3.2 Shale Inhibition

Hec inogona kubatsira kuti shale inhibition nekuumba chipinganidzo chekudzivirira pamadziro ellbore. Izvi zvinobatsira kudzivirira kuzvimba uye kuparadzaniswa kwehasha mafomu, kuchengeta yakanyatsogadzikana kugadzikana.

3.3 Yakarasika Kutenderera Kudzora

Mukudhirowa zvinodhaka uko kurasikirwa kwehunhu kune kuumbwa, hec kunogona kuverengerwa mukuumbwa kubatsira kudzora kwakarasika, kunoita kuti mvura yekukwevera inosara muTellbore.

4. Kufunga uye zvingangodaro

4.1 Kusimbiswa

Kuvhiringidzika kwehec mukurova kwemvura kunoda kudzorwa zvakanyanya kuti uwane zvimiro zvaunoda zvaunoda pasina kukonzera kuomarara kana kukanganisa zvimwe zvinhu zvemvura.

4.2 Kuenderana

Kuwirirana nedzimwe dhizaini yemvura yekuwedzera uye zvikamu zvakakosha. Kunyatsofungisisa kunofanirwa kupihwa kune yese yekuumbwa kudzivirira nyaya dzakadai sekuparadza kana kuderedzwa kushanda.

4.3 Fluid Filt Filt Control

Ipo herc inogona kubatsira pakurasikirwa kwekurasikirwa kwemvura, mamwe mawokuwedzera anogona kuvewo madikanwa kugadzirisa nyaya dzakareruka dzemvura uye chengetedza kudzora kwesimba.

5. Mhedziso

HydroxytHyl cellulose inotora basa rakakomba mumafuta ekudhiraivha eyemafuta nekupa mukubudirira uye kugadzikana kwekuchera mvura. Semumiriri wevasikisi, inobatsira kudzora zvinhu zvemvura, kumisa kucheka, uye kuchengetedza hutano hwakanaka. Vagadziri vanofanirwa nekunyatsofunga nezvekunyatsofunga, uye kuwirirana, uye kuumbwa kwakazara kuti vave nechokwadi chekuti hec inowedzera mabhenefiti ayo ekuchera mairi.
