Ndezvipi zvikamu zvePDM Drill (Progressing Cavity Drill)?

PDM Drill idhiri remagetsi rinoburitswa pasi rinoshandisa mvura yekuboorera sesimba rekushandura simba rekumanikidzwa kwemvura kuita simba remakanika.

Zvikamu

PDM Drill ine zvikamu zvikuru zvina: bypass valve, hydraulic motor, cardan shaft, uye drive shaft. Screw motor (hydraulic motor) ndiyo inonyanya kukosha pa drill.

1. Kuungana kweVharuvhu Yekupfuura

Vharuvhu yekubvisa mvura inogadzirwa nemuviri wevharuvhu, chifukidziro chevharuvhu, chifukidziro chevharuvhu, nechitubu. Kana yamanikidzwa, chifukidziro chevharuvhu chinotsvedza mukati mechifukidziro chevharuvhu, uye kufamba kwechikamu chevharuvhu kunochinja mafambiro emvura—zvichipa vharuvhu yekubvisa mvura inotsvedza mamiriro maviri: kupfugama nekuvhara.

Paunenge uchidonha uchipinda nekubuda mugomba: Maburi anobuda mugomba revharuvhu nemuviri wevharuvhu haana kuvharwa, saka vharuvhu inodarika inenge iri muchimiro chepasi pevhu, zvichiita kuti dhaka riri mutambo wekuboorera ripfuure mota ripinde mugomba repasi pevhu.

Kana mwero wekuyerera kwevhu nekumanikidzwa kwasvika padanho rakatarwa: Chinovhara vharuvhu chinodzika pasi kuti chivhare gomba revharuvhu rinotenderera. Panguva ino, vhuruvhu rinoyerera nemumota, richishandura simba rekumanikidzwa kuita simba remuchina.

Kana mwero wekuyerera kwevhu wakaderera zvakanyanya kana kuti pombi yamiswa: Chitubu chinosundira pakati pevharuvhu kumusoro, uye gomba revharuvhu rinovhurwa—zvichidzosera vharuvhu kumamiriro ekupfuura.

2.Mota yeHydraulic

Mota ye hydraulic ine stator ne rotor. Stator inogadzirwa nekupinza rabha mumadziro emukati mepombi yesimbi, uye buri rayo remukati i helix rine ma parameter chaiwo e geometric. Rotor i screw rod ine coating yakaoma. Rotor ne stator mesh pamwe chete, uye helical yakavharwa cavity inoumbwa nekusiyana kwema leads avo kusvika pakushandurwa kwesimba kwakakwana.

Helix yemota rotor inogona kuva yekutanga kamwe chete kana kutanga kakawanda:

Kutanga kushoma kwerotor kunoita kuti kumhanya kwese kwese kuenderere mberi uye torque yakaderera;

Kutanga kwakawanda kwerotor kunoita kuti kumhanya kwerotor kuderera uye torque yakakwira.

3. Mugodhi weCardan

Basa remuchina weCardan nderekushandura kufamba kwemota kuita kutenderera kwemuchina weDrive shaft, uye kutumira torque nekumhanya kwekutenderera kunogadzirwa nemota kuenda kumuchina weDrive shaft (uye pakupedzisira kuDrill bit). Mazhinji emuchina weCardan shaft anoshandisa dhizaini yemuchina unochinjika.

4. Mugodhi weDrive

Mubato wekutyaira une basa rekutumira simba rekutenderera kwemota kuenda kugomba rekuboorera, ukuwo uchitakura mitoro yeaxial neradial inogadzirwa nehuremu hwepabhati (WOB). Saka, mubato wekutyaira unoda kuomarara kwakanyanya, kuramba kupfeka, uye hupenyu hurefu hwebasa. Muchiitiko ichi, kudzima kupisa kunogona kuwedzera hupenyu hwebasa remubato wekutyaira zvakanyanya.
