Iwo Basics of Reverse Circulation Drilling
Horizontal directional drilling hachisi chinhu chitsva.Vanhu vakachera matsime makore anopfuura 8,000 apfuura kuitira mvura yepasi pevhu munzvimbo dzinopisa uye dzakaoma, kwete nePDC bits nemadhaka mota sezvatinoita nhasi.
Pane zvinhu zvakawanda zvekufunga nezvazvo pakusarudza nzira yekuchera.Ichi chirevo chakanyanya kuitika kana iwe uchichera kutsvaga kana giredhi kutonga.Mazhinji makondirakiti uye mainjiniya epetroleum anowanzo sarudza kudhiraivha kutenderera nekuti inopa mabhenefiti akawanda pane dzimwe nzira dzekuchera.
Tisati taratidza mabhenefiti ereverse circulation drilling, ngatitsanangurirei kuti chii chemufananidzo wakajeka.
Chii chinonzi Reverse Circulation Drilling?
Reverse circulation drilling inzira yekuchera iyo inoshandisa reverse circulation PDC bits, uye matanda ane madziro maviri kuti awane kuchera uye sampuli yekuunganidza.Rusvingo rwekunze rune machubhu emukati anobvumira kuti kucheka kudzoserwe kumashure kumusoro sezvo kuchera kunoenderera mberi.
Reverse circulation ichiri kubvumira kusungirirwa kwemaburi ekuvhura asi kunosiyana nekuchera madhaimani pakuti inounganidza matombo ekucheka pachinzvimbo chedombo core.Chibooreso chinoshandisa akakosha reverse circulation bits anofambiswa nepneumatic reciprocating piston kana sando.
Aya madhiri ekutenderera anotenderera anogadzirwa netungsten, simbi, kana musanganiswa wezviviri nekuti akasimba zvekudambura nekupwanya dombo rakaomarara.Kuburikidza nekufamba kwayo kwepiston, sando inokwanisa kubvisa dombo rakapwanyika, rinobva raendeswa kumusoro nemhepo yakamanikidzwa.Mhepo inovhuvhuta ichidzika pasi.Izvi zvinogadzira shanduko yekumanikidza inokonzeresa kutenderera kutenderera, izvo zvinoendesa kuchekwa kumusoro kwechubhu.
Reverse circulation drilling yakanakira sampuli yepasi pedombo nyaya yekuongorora stratification uye nheyo dzeinjiniya zvinangwa.
Zvino zvauri kuziva kuti chii, ngatitarisei mamwe mabhenefiti ereverse circulation drilling.
Inobatsira Kuwana Zvisina Kusvibiswa Samples
Reverse circulation drilling inobvisa chero kusvibiswa kwematombo akachekwa kana aendeswa pamusoro, sezvo kucheka kunofamba nemuchubhu yemukati yakavharirwa nekuvhura kumwe chete pamusoro panounganidzwa sample.Iwe unogona, saka, kuunganidza nhamba huru yemhando yepamusoro sampuli yekuongorora.
Incredible Penetration Rates
Iwo akasarudzika reverse kutenderera mabheti akasimba zvakanyanya kupfuura akajairwa kupedzisa mabhiti nekuda kwetungsten-simbi inoumbwa mazano.Reverse circulation drills inoshanda nekukasira mitengo uye inotora zvakachekwa munguva yekurekodha.Velocity iyo zvicherwa zvinodzoserwa kumusoro zvinogona kudongorera zviri nyore pamamita 250 pasekondi.
Kusiyana-siyana Mumamiriro Akashata
Reverse circulation drilling haisi nzira yakaoma uye haidi mvura yakawanda.Iyi ficha inoita kuti reverse circulation drilling ive yakanaka kunyangwe munzvimbo dzine mvura shoma senge nzvimbo dziri kunze kana nzvimbo dzakaoma.
Zvishoma Zvinodhura
Reverse circulation drilling inodhura zvakanyanya, kunyanya zvichienzaniswa nekuchera madhaimani.Kwete chete nekuda kwekuderedzwa kwemutengo wekushanda, asiwo nekuda kwenguva pfupi inotora kupedzisa kuchera.Pakazere, kucheresa kutenderera kutenderera kunogona kuita mari inosvika 40% isingasviki pakuchera kwakajairika.Kana iwe uchichera munzvimbo dzine hutsinye, mutengo-unoshanda unogona kutopetwa kaviri.
Reverse Circulation yeGiredhi Kudzora
Hunhu hwemasamples akawanikwa hwakakosha zvakanyanya muchirongwa chekuongorora kuita kwakaringana kuronga kwemugodhi kana kuisa zvinoputika.Kudzora kwegiredhi ndiko kunoshandiswa kutsanangura mabhuroki uye mamakisi ematombo.Reverse circulation drilling yakanakira giredhi control nekuti:
- Inoda kubata kushoma pane dzimwe nzira
- Samples dzakawanikwa hadzina chero zvinosvibisa
- Inokurumidza kutenderera nguva
- Samples dzakawanwa dzinogona kuendeswa ku lab kuti dziongororwe
Chinhu chakanyanya kukosha chechero reverse kutenderera kudhiraivha kushanda ndeye sampuli yekucheka.Nzira dzakawanda dzinogona kushandiswa kudzoreredza sampuli, asi chinangwa chikuru ndechekuwana akawanda emhando yemasampuli sezvinobvira munguva pfupi pfupi.
Kana iwe uchida chero reverse circulation yekuchera masevhisi, rangarira kutsvaga chete nyanzvi dzine marezenisi dzinoziva nzira yavo yekutenderedza reverse circulation drill uye vanonyatsoziva maitiro akasiyana.Kumbira kuti vangoshandisa zvakasimbiswa zvemhando yepamusororeverse circulation PDC bitskudzivirira chero kunonokera kunokonzerwa nekutyoka kwezvibooreso.Chekupedzisira, gara uine chokwadi chekuti nzira yekuchera inoenderana neyakatemerwa yezvakatipoteredza zviyero.
