Drilling Fluid Additives |HEC, CMC, PAC

Drilling fluid additives, kusanganisira HEC (hydroxyethyl cellulose), CMC (carboxymethyl cellulose), uye PAC (polyanionic cellulose), zvinhu zvakakosha zvinoshandiswa muindasitiri yemafuta negasi kusimudzira kushanda kwemvura yekuchera.Heino kupatsanurwa kwemabasa avo uye mabasa:

1. HEC (Hydroxyethyl Cellulose):
   • Viscosity Control: HEC ipolymer inonyungudika nemvura iyo inowanzo shandiswa semugadziriso we viscosity mukuchera zvinwiwa.Inobatsira kuwedzera viscosity yemvura, iyo yakakosha pakutakura uye kumisa kucheka kwekucheka, kunyanya mumatsime akamira kana akatsauka.
   • Fluid Loss Control: HEC inogona zvakare kushanda seyekurasikirwa kwemvura yekudzora mumiriri, ichidzikisa kurasikirwa kwemvura yekuchera mukuumbwa.Izvi zvinobatsira kuchengetedza wellbore kugadzikana uye kudzivirira inodhura kugadzirwa kukuvara.
   • Temperature Stability: HEC inoratidza kugadzikana kwakanaka kwekushisa, ichiita kuti ive yakakodzera kushandiswa mune zvose zviri zviviri zvepamusoro-tembiricha uye pasi-tembiricha yekuchera nharaunda.
   • Iine Ushamwari Nezvakatipoteredza: HEC inoodza uye ine hushamwari kwezvakatipoteredza, zvichiita kuti ive sarudzo inosarudzika kushandiswa mukuchera zvinwiwa, kunyanya munzvimbo dzinokanganisa nharaunda.
2. CMC (Carboxymethyl cellulose):
   • Viscosity Modifier: CMC imwe polymer inonyungudika nemvura inowanzoshandiswa sechinakisiso chinogadzirisa mumvura yekuchera.Inobatsira kuvandudza rheological properties yemvura, kuwedzera simba rekutakura uye kumiswa kwekucheka kwekucheka.
   • Fluid Kurasika Kudzora: CMC inoshanda seyekurasikirwa kwemvura yekudzora mumiriri, ichidzikisa kurasikirwa kwemvura mukuumbwa uye kuchengetedza wellbore kugadzikana panguva yekuchera mabasa.
   • Kushivirira Munyu: CMC inoratidzira kushivirira kwakanaka kwemunyu, ichiita kuti ive yakakodzera kushandiswa mukuchera zvinwiwa mune saline maumbirwo kana panowanikwa munyu wakanyanya.
   • Thermal Kugadzikana: CMC ine kugadzikana kwakanaka kwekupisa, ichiibvumira kuchengetedza kuita kwayo kunyangwe kune tembiricha yakakwira inosangana mukuchera kwakadzika.
3. PAC (Polyanionic Cellulose):
   • High Viscosity: PAC ndeyepamusoro-molecular-huremu polymer inopa yakakwira viscosity kumvura yekuchera.Inobatsira kuvandudza simba rekutakura remvura uye inobatsira mukumiswa kwekucheka kwekucheka.
   • Fluid Kurasika Kudzora: PAC inoshanda inodzora kurasikirwa kwemvura, inoderedza kurasikirwa kwemvura mukuumbwa uye kuchengetedza wellbore kugadzikana.
   • Temperature Stability: PAC inoratidza kugadzikana kwemafuta kwakanakisa, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzekuchera dzepamusoro-soro, dzakadai semvura yakadzika kana geothermal drilling.
   • Yakaderera Yekukuvadza Kukuvadzwa: PAC inoumba keke yakatetepa, isingapindike yekusefa pachiso chechimiro, ichidzikisa njodzi yekukuvara kwekugadzira uye kugadzirisa zvakanaka kugadzirwa.

Izvi zvinowedzera mvura yekuchera, zvinosanganisira HEC, CMC, uye PAC, zvinotamba mabasa akakosha mukugadzirisa mashandiro ekuchera nekudzora zvivakwa zvemvura, kuderedza kukuvadzwa kwekuumbwa, uye kuona kugadzikana kwetsime.Sarudzo yavo nekushandiswa kunoenderana nemamiriro ekuchera, senge maitiro ekuumba, kudzika kwetsime, tembiricha, uye munyu.
