Mmetụta nke Hydroxyethyl Cellulose na Oilfields

Hydroxyethyl cellulose (HEC) na-achọta ọtụtụ ngwa na ụlọ ọrụ mmanụ na gas, karịsịa n'ubi mmanụ. Nke a bụ ụfọdụ mmetụta na ojiji HEC na arụ ọrụ mmanụ:

1. Fluids Drilling: A na-agbakwunye HEC na mmiri na-egwupụta ihe iji chịkwaa viscosity na rheology. Ọ na-arụ ọrụ dị ka viscosifier, na-enye nkwụsi ike na ịkwalite ikike ibu nke mmiri mmiri na-egwupụta ihe. Nke a na-enyere aka ịkwụsịtụ mkpọmkpọ ebe na ihe ndị ọzọ siri ike, na-egbochi ha idozi na ịkpata mgbochi na olulu mmiri.
2. Njikwa okirikiri furu efu: HEC nwere ike inye aka chịkwaa mgbasa ozi furu efu n'oge a na-arụ ọrụ mkpọpu site n'ịme ihe mgbochi megide mfu mmiri n'ime usoro porous. Ọ na-enyere aka mechie mgbaji na mpaghara ndị ọzọ na-emebi emebi na nhazi ahụ, na-ebelata ohere nke mgbasa ozi na-efunahụ na enweghị ntụkwasị obi.
3. Wellbore Cleanup: Enwere ike iji HEC mee ihe dị ka ihe na-eme ka mmiri dị ọcha nke ọma wepụ ihe mkpofu, nsị mmiri, na nzacha achicha site na olulu mmiri na nhazi. Ya viscosity na nkwusioru Njirimara na-enyere aka na-ebupụ siri ike irighiri na ịnọgide na-enwe mmiri agagharị n'oge mkpocha ọrụ.
4. Enwekwukwa mmanu mmanu (EOR): N'ime ụfọdụ ụzọ EOR dị ka idei mmiri polymer, enwere ike iji HEC dị ka ihe na-eme ka ọ dịkwuo mma iji mee ka viscosity nke mmiri ma ọ bụ ihe ngwọta polymer tinye n'ime ọdọ mmiri ahụ. Nke a na-eme ka ịsa ahụ dị mma, na-ebupụ mmanụ karịa, ma na-eme ka mmanụ nwetaghachi site na mmiri mmiri.
5. Njikwa mkpofu mmiri mmiri: HEC dị irè na ịchịkwa mfu mmiri na slurries ciment eji arụ ọrụ ciment. Site akpụ a mkpa, impermeable nyo achicha na guzobe ihu, ọ na-enyere aka gbochie oke mmiri mmiri ọnwụ ka e guzobere, n'ịhụ kwesịrị ekwesị zonal iche na ọma iguzosi ike n'ezi ihe.
6. Fluids na-agbaji: A na-eji HEC na mmiri mmiri na-agbaji hydraulic iji nye viscosity na njikwa mfu mmiri. Ọ na-enyere aka iburu proppants banye n'ọkpụkpụ ahụ ma nọgide na-enwe nkwusioru ha, na-eme ka ọkpụkpụ na-agbaji dị irè na mgbake mmiri n'oge mmepụta.
7. Mmalite nke ọma: Enwere ike itinye HEC n'ime mmiri acidizing na ọgwụgwọ ndị ọzọ na-akpali akpali iji meziwanye rheology nke mmiri, na-achịkwa mfu mmiri, ma kwalite ndakọrịta mmiri na ọnọdụ nchekwa. Nke a na-enyere aka ịkwalite arụmọrụ ọgwụgwọ yana ịbawanye arụpụta nke ọma.
8. Mmiri Mmecha: Enwere ike ịgbakwunye HEC na mmiri mmecha iji mezie viscosity na nkwusioru ihe onwunwe ha, na-ahụ na mkpọ gravel dị irè, njikwa ájá, na mkpocha nke ọma n'oge arụ ọrụ mmecha.

Hydroxyethyl cellulose (HEC) na-arụ ọrụ dị oke mkpa na ngwa mmanụ dị iche iche, na-enye aka na ịrụ ọrụ nke ọma, nkwụsi ike nke olulu mmiri, njikwa mmiri, na njikarịcha mmepụta. Ngbanwe ya, ịdị irè ya na ndakọrịta na mgbakwunye ndị ọzọ na-eme ka ọ bụrụ akụkụ bara uru na sistemu mmiri na ọgwụgwọ mmanụ.
