Kunzwisisa Drilling Fluid
Mvura yekuchera, inozivikanwawo semadhaka ekuchera, inoshanda sechinhu chinoshanda chakawanda chakakosha pakuchera mumaindasitiri akasiyana, anosanganisira oiri negesi, geothermal, uye migodhi.Chinangwa chayo chikuru ndechekubatsira mukuchera zvibhorani, kuchengetedza mutsime kugadzikana, kutonhora nekuzora chibhorani, kutakura zvicherwa zvekuchera pamusoro, nekudzivirira kukuvara kwekugadzira.Drilling fluid musanganiswa wakaoma unosanganisira zvinhu zvakasiyana-siyana zvakagadzirirwa kusangana nezvinodiwa zvekuchera.
Zvinoumba Drilling Fluid:
Base Fluid: Iyo base fluid inoumba hwaro hwemvura yekuchera uye inogona kunge iri mvura, mafuta, kana synthetic-yakavakirwa, zvichienderana nemamiriro ekuchera uye mirau yezvakatipoteredza.Mvura-yakavakirwa mvura inowanzoshandiswa nekuda kwekudhura kwayo uye kushamwaridzana kwezvakatipoteredza.
Additives: Zvinowedzerwa zvinosanganiswa mumvura yekuchera kuti iwedzere kushanda kwayo uye kugadzirisa matambudziko anowanikwa panguva yekuchera.Izvi zvinowedzera zvinosanganisira viscosifiers, filtration control agents, lubricant, shale inhibitors, zvinorema, uye fluid kurasikirwa control agents.
Kuyeresa Zvishandiso: Zviyereso zvehuremu, senge barite kana hematite, zvinowedzerwa kuwedzera kuwanda kwemvura yekuchera, zvichiita kuti iite kudzvanyirira kwakaringana kupikisa maumbirwo anowanikwa pakadzika.
Rheology Modifiers: Rheology modifiers inodzora kuyerera kwemvura yekuchera, kuve nechokwadi kumiswa kwakaringana kwekuchekwa kwekuchera uye kufambisa kwakanaka kuenda pamusoro.Yakajairika rheology modifiers inosanganisira bentonite, polymers, uye xanthan chingamu.
Corrosion Inhibitors: Corrosion inhibitors inosanganisirwa kuchengetedza midziyo yekucheresa uye zvikamu zvekudzika kubva kune zvinosvibisa zvinhu zviri mumvura yekugadzira.
Biocides: Mabiocides anodzivirira kukura kwebhakitiriya uye tupukanana mukati memvura yekuchera, kuderedza njodzi ye microbiologically induced corrosion (MIC) uye kuchengetedza kugadzikana kwemvura.
Kusiyanisa Kuchera Madhaka kubva kuDrilling Fluid
Nepo kuchera madhaka uye mvura yekuchera ichiwanzo shandiswa zvakasiyana, dzimwe nyanzvi dzinoita mutsauko pakati pematemu maviri aya zvichienderana nemidziyo nemashandisirwo azvo.
Kuchera Madhaka: Sechinyakare, madhaka ekuchera anoreva zvakananga kumafuta-anocherwa zvinwiwa.Madhaka ekuchera anowanzo aine base fluid inoumbwa neyakacheneswa petroleum zvigadzirwa kana maoiri ekugadzira.Oiri-akavakirwa madhaka anopa mabhenefiti akadai sekuvandudzwa kwemafuta, kugadzikana kwekushisa kwepamusoro, uye kusimbaradzika kwematsime mune mamwe mafomati.
Drilling Fluid: Nekusiyana, mvura yekuchera inobatanidza chikamu chakafara chinosanganisira zvese-zvinobva mumvura uye nemafuta-based maumbirwo, pamwe neanogadzira-akavakirwa zvinwiwa.Mvura-yakavakirwa mvura yekuchera, iyo inoumba kuwanda kwemabasa ekuchera, anowanzo kunzi semvura yekuchera.Mvura-yakavakirwa mvura inofarirwa munzvimbo dzakawanda dzekuchera nekuda kwekuenderana kwezvakatipoteredza, mutengo wakaderera, uye nyore kurasa.
Zvikumbiro uye Zvinetso
Applications:
Kuchera Kwekuongorora: Mvura yekuchera inoita basa rakakosha mukuongorora kuchera, uko chinangwa chikuru ndechekuongorora pasi pepasi geology uye kuona anogona hydrocarbon reservoirs.
Kuvaka Matsime: Panguva yekuvakwa kwetsime, mvura yekuchera inobatsira mukudzikamisa tsime, kudzora mafambiro ekugadzira, uye kufambisa kuiswa kwecasing nesimende.
Formation Evaluation: Mvura yekuchera inogonesa kudzoserwa kwemasampuri epakati uye kufambisa nzira dzakasiyana dzekuongorora maumbirwo, kusanganisira kutema matanda uye kuyedzwa.
Zvinetso:
Zvemamiriro ekunze: Kuraswa kwemvura yekuchera kunounza matambudziko ezvakatipoteredza, kunyanya mukuchera kumahombekombe uko kune mitemo yakasimba inodzora kuyerera munzvimbo dzemugungwa.
Kukuvadzwa Kwemaumbirwo: Zvinwiwa zvisina kugadzirwa zvakanaka zvinogona kukonzera kukuvara kwekuumbwa, kukanganisa kugadzirwa kwetsime uye hupenyu hurefu.Kudzora kuumbwa kwemvura uye kusefa zvinhu kwakakosha kudzikisa njodzi iyi.
Fluid Loss: Kurasika kwemvura, kana kupinza kwemvura yekuchera mukugadzira, kunogona kutungamirira kune wellbore kusagadzikana, kurasika kutenderera, uye kuderera kwekuchera.Kubatanidza mashandiro ekudzora kurasikirwa kwemvura kwakakosha kugadzirisa nyaya iyi.
nepo mazwi okuti "dhaka rekuchera" uye "mvura yekuchera" achiwanzo shandiswa zvakasiyana, anogona kureva kuumbwa kwakasiyana kwakasiyana uye mashandisirwo mukati memamiriro ekuchera.Mvura yekuchera inoshanda sechinhu chakasiyana-siyana chakakosha pakuchera chibhorani, ichipa mashandiro akadai sekuzora, kuchekwa kwekutakura, uye kugadzikana kwechitsime.Ingave yakavakirwa pamvura, mafuta-yakavakirwa, kana kugadzirwa, kuumbwa kwemvura yekuchera inogadzirwa kuti isangane nematambudziko ekuchera uchitevedzera mirairo yezvakatipoteredza.Nekunzwisisa kuomarara kwekudhirowa kwemvura yekudhirowa uye maitiro, mainjiniya ekuchera nevashandisi vanogona kukwidziridza mashandiro ekuchera uku vachideredza kukanganisa kwezvakatipoteredza uye kuve nechokwadi chekuvimbika.
