Mota yeDownhole Positive Displacement (PDM Drill)

Chibooreso chePDM (Positive Displacement Motor) imota inoburitswa mugomba rinopinda mugomba rinoshandisa mvura yekuboorera sesimba rekushandura simba remahydraulic kuita simba remuchina. Kana matope anopombwa nepombi yematope achiyerera nepakativharuvhu yekupfuurauye ichipinda mumota, pane musiyano wekumanikidzwa kunoumbwa pakati pekupinda nekunze kwemota. Izvi zvinosunda rotor kuti itenderere kutenderedza stator's axis, zvichitumira kumhanya netorque kuburikidza neuniversal joint uye drive shaft kuenda kudrill bit, zvichiita kuti zvikwanise kuchera.

Zvikamu Zvikuru

Chibooreso chePDM chinowanzo kuve nezvikamu zvikuru zvina: vharuvhu yekupinda,mota yedhaka, joini yepasi rose, uye mubato wekutyaira.

Mota yescrew ndiyo chinhu chikuru chemudziyo. Zvichienderana nemaitiro uye ongororo yedzidziso, kuti mota ishande zvakanaka, kudonha kwepressure padanho rega rega remota hakufanirwe kudarika 0.8 MPa. Zvikasadaro, mota inogona kudonha, zvichikonzera kudzikira nekukurumidza kwespeed kana kumira zvachose, izvo zvinogona kukuvadza mota.

Mutsetse mumwe chete wemota unotsanangurwa sedanho rimwe chete. Mwero wekuyerera kwematope unoshandiswa panzvimbo yacho unofanirwa kuramba uri mukati mehuwandu hunokurudzirwa; zvikasadaro, zvichakanganisa kushanda zvakanaka kwemota uye zvinogona kuwedzera kupera. Maparamita ekushanda kwemota yescrew ndiwo maparamita ekutanga ekushanda kwePDM drill.

Torque yekubuda kwemota inoenderana nekudonha kwekumanikidzwa, nepo kumhanya kwekubuda kwacho kunoenderana nekuyerera kwematope anopinza. Sezvo mutoro uchiwedzera, kumhanya kwekutenderera kwechishandiso kunoderera. Naizvozvo, nekudzora kuverenga kwe pressure gauge uye kumhanya kwekuyerera kwepombi pamusoro, torque yekudzika uye kumhanya kwekutenderera zvinogona kudzorwa.

Chikamu cheVharuvhu Yekupfuura

Vharuvhu yekubvisa mvura inosanganiswa nemuviri wevharuvhu, sleeve yevharuvhu, spool yevharuvhu, chitubu, nezvimwe zvinhu. Pasi pesimba rekumanikidzwa, spool yevharuvhu inotsvedza mukati me sleeve yevharuvhu. Kufamba kwe spool yevharuvhu kunochinja divi rekuyerera kwemvura, izvo zvinogona kuisa vharuvhu yekubvisa mvura muchimiro che bypass kana closed state.

Pakugumburwa nekubuda, nzira dziri muvharuvhu nemuviri wevharuvhu hadzina kuvharwa, saka vharuvhu yekupinda inenge iri muchimiro chekupinda. Izvi zvinobvumira matope kubva patambo yekuboorera kuti apfuure mota opinda mu annulus.

Kana mwero wekuyerera kwevhu uye kumanikidzwa kwaro zvasvika pachiyero chakatarwa, vharuvhu inodzika, ichivhara mavharuvhu anotenderera. Zvadaro, vhu rinoyerera nemumota, richishandura simba re hydraulic kuita simba re mechanical.

Kana mwero wekuyerera kwevhu wakaderera zvakanyanya kana kuti pombi yamiswa, chitubu chinosundira vharuvhu kumusoro, chichivhura maburi epadhuze uye chinoisa vharuvhu muchimiro chepadhuze.

Mota (Chikamu cheSimba)

Mota iyi ine stator nerotor. Stator inoumbwa nekupinza rabha muchubhu yesimbi. Bore rayo remukati rine chimiro chespiral chine ma parameter chaiwo ejometri. Rotor idanda re screw rine pamusoro wakaoma.

Rotor ne stator mesh pamwe chete. Musiyano uripo pakati pemaleads avo unogadzira makomba akavharika, izvo zvinoita kuti simba rishandurwe.

Ma helices emota rotor anogona kuva single-lobe kana multi-lobe. Kana rotor lobes dzishoma, kumhanya kwacho kwakakwira uye torque yakadzikira; kana lobes dzakawanda, kumhanya kwacho kwakaderera uye torque yakakwira.

Joinhi Yese

Basa rejoini repasi rose nderekushandura kufamba kwepasi kwemota kuita kutenderera kwakagadzika kwejoini redhiraivha uye kutumira torque nekumhanya kunogadzirwa nemota kuenda kujoini redhiraivha uye gare gare kuenda kubhori. Rudzi rwejoini repasi rose rinochinjika rinowanzoshandiswa.

Mugodhi weDrive

Basa remuchina wekutyaira nderekutumira simba rinotenderera remota kuenda kuchikamu chekuboorera uku uchitsungirira mitoro yeaxial neradial inogadzirwa nehuremu huri pachikamu. Saka, muchina wekutyaira unoda kuomarara kwakanyanya, kuramba kupfeka, uye hupenyu hurefu hwebasa. Kudzima kupisa kunogona kuwedzera hupenyu hwebasa remuchina wekutyaira.
