Kuvandudzwa kwehunyanzvi hwekuchera tekinoroji kunonyanya kutsamira pane yakasimba yekudzora michina.Mechanical yakasimba kudzora chinhu chakakosha chekuchengetedza uye kuve nechokwadi chekuita kwakanaka kwekuchera madhaka, uye zvakare chimwe chezvikamu zvezvakajairwa kuchera tekinoroji.
Mukuchera madhaka, saizi yezvimedu zvakasimba zvine simba guru pakushanda kwedhaka uye chiyero chemagetsi chekupinda chinodarika 15 microns, inoverengera inosvika makumi manomwe muzana ezvese zvakaonda.Vanhu vanoedza kuibvisa chero nguva kuburikidza nemichina inoshanda yakawanda.Nekuvandudzwa kwekuchera tekinoroji, zvinodiwa pakuita kwedhaka zvakakwirira uye zvakakwirira.Kudzidzira kwakaratidza kuti tekinoroji yekuvandudza mashandiro edhaka nekudzora madhaka akaomarara yakave yakakosha tekinoroji yekuchera madhaka, inowirirana zvakanyanya nekudzikamisa mamiriro etsime uye kuvandudza kumhanya kwekuchera.Kuti upe madhaka emhando yepamusoro ekuchera, zvinodikanwa kuve neseti yemidziyo yakakwana uye inoshanda yekuchenesa dhaka, inova vimbiso yekuchengetedza kuita kwakanakisa kwekuchera madhaka.
Iyo yakasimba chikamu mukuchera mvura uye madhaka inogona kukamurwa muzvikamu zviviri zvinoenderana nemabasa avo: imwe inobatsira yakasimba chikamu, senge bentonite, kemikari kurapwa mumiririri, barite upfu, etc. Imwe yacho haibatsiri yakasimba, sekuchera cuttings, murombo bentonite, jecha, nezvimwewo.
Iyo inonzi solid phase control yekuchera mvura ndeyekubvisa inokuvadza yakasimba chikamu uye kuchengetedza inobatsira yakasimba chikamu kuti isangane nezvinodiwa zvekuchera tekinoroji pakuita kwemvura yekuchera.Kazhinji, kutonga kwakasimba kwemvura yekuchera kunonzi kusimba kwakasimba.
Kukosha kwekutonga kwakasimba kuri kutariswa.Yakava chinhu chakakosha chinobata zvakananga kuchera kwakachengeteka, kwepamusoro-soro uye kunoshanda uye kuchengetedzwa kwemafuta uye gasi reservoirs.Kudzora kwakasimba ndiyo imwe yenzira dzakakosha dzekuwana kuchera kwakaringana.Kudzora kwakanaka kwakasimba kunogona kupa mamiriro anodiwa ekuchera kwesainzi.Yakakodzera yakasimba chikamu chekutonga chinogona kuchengetedza oiri negasi reservoir, kuderedza kuchera torque uye friction, kuderedza kusimba kwekuchinja kweannulus suction, kuderedza mukana wekusiyanisa kumanikidza kunamatira, kunatsiridza kumhanya kwekuchera, kuwedzera hupenyu hwechibhorani, kuderedza. kupfekedzwa kwemidziyo nemapombi, kunatsiridza hupenyu hwenzvimbo dzisina njodzi dzechibhorani chemvura inotenderera, kuwedzera kugadzikana kwegomba, kunatsiridza mamiriro ekuisa, kuderedza kusvibiswa kwezvakatipoteredza, uye kuderedza mutengo wekuchera mvura.The field statistical data inoratidza kuti mu low density range, the mechanical penetration rate inogona kuwedzerwa ne8% yega yega kuderedzwa kwe1% mune yakasimba yemvura yekuchera (yakaenzana ne0.01 kuderera muhuwandu hwemvura yekuchera).Zvinogona kuonekwa kuti zvikomborero zvekutonga kwakasimba zvakakosha zvikuru.
Kuvapo kwekunyanya kusimba kusingabatsiri mumatope ndiyo ngozi huru yakavanzika yekukuvadza kushanda kwemvura yekuchera, kuderedza chiyero chekupinda uye kutungamirira kumatambudziko akasiyana-siyana.Mukuita kwenguva refu uye kuenderera mberi kwekutsvaga, vanhu vakagumisa kuti yakawandisa isingabatsiri chikamu chakasimba mumadhaka chichaunza zvinotevera zvinokanganisa basa rekuchera.
Iyo yakakwirira yakasimba yemukati medhaka, yakakura chaiyo giravhiti, uye kuwedzera kwepasi pasi pegomba kudzvanywa kwemusiyano kunowedzera simba rekubata kwekoramu yemvura padombo, izvo zvisingakodzeri kutsemuka kwedombo kuzasi kwegomba.Iyo yakasimba yedhaka yakakwira, kugona kutakura zvicherwa zvekuchera kwakadzikira, uye nhamba huru yezvimedu zvakakura zvekuchera zvicherwa hazvigone kuburitswa mugomba nenguva, zvichikonzera kudzokororwa kudzokororwa kwematombo ekucheka neiyo drill bit, uye nokudaro kuwedzera kupfekwa kwemidziyo yekuchera, zvichikanganisa kumhanya kwekuchera.
Munguva yekuchera, kurasikirwa kwemvura uye yakasimba particle yemukati medhaka inozokanganisa zvakananga kunaka kwedhaka keke rakaumbwa pamadziro gomba.Kurasikirwa kwemvura yemvura yekuchera idiki, keke yedhaka yakaonda uye yakaoma, uye kudzivirira kwemadziro kwakanaka, ndicho chinangwa chedu.Iyo yakakwirira yakasimba yemukati ichawedzera kurasikirwa kwemvura mumadhaka, izvo zvinozoita kuti kunyura kwemvura, hydration yekuwedzera uye gomba madziro kusagadzikana kwekuumbwa kwe shale, zvichikonzera kusasimudza uye kugumburwa, zvichikonzera tsaona mugomba.Mukuwedzera, kana keke yematope yakanyanyisa uye yakasununguka, inowedzerawo nzvimbo yekubatana pakati pechigadziro chekuchera uye rusvingo rwetsime, izvo zvinotungamirira nyore nyore kunamatira njodzi.
Iyo yakakura iyo yakasimba yemukati, iyo yakakura yekupfeka kwemakanika yeinotenderera system.Madhaka akawandisa anomhanyisa kupfeka kwecylinder liner uye piston yepombi yedhaka, nekudaro kuwedzera nguva yekuchengetedza uye kuderedza kuchera.Kana iyo yakasimba yemukati yakawandisa, inokonzeresa kuyera pamadziro emukati mepombi yekuboorera, kukanganisa kuredza kwepombi yemukati, uye kumanikidzwa kusimudza pombi yekuboorera kubata kuyera, nekudaro kukanganisa maitiro akajairika ekushanda.Kubudirira kwekuchera kuchaderedzwawo zvakanyanya nekuda kwekuwedzera kukuru kwekubatsira nguva yekushanda.
Panguva yekuchera, kuita kwedhaka kunoshanduka kana makucheka akasabviswa nenguva nekuti anogara achipinda mumatope.Kana jecha riri mumatope richipfuura 4%, rinoonekwa semarara slurry.Inofanira kubudiswa uye kutsiviwa neslurry itsva.Mazhinji ematope ndiwo mhinduro yealkaline, uye kubuda kwechinyakare hakungoparadzi zvinomera chete, asiwo kukonzeresa alkalization yevhu uye kunokanganisa kuvandudzwa kwezvinomera.Mukuwedzera, kune zvimwe zvinowedzera mumatope izvo zvinoita kuti dhaka rive dema, uye huwandu hwakawanda hwekubuda huchakonzera kusvibiswa kwekuona kune zvakatipoteredza.
