Zvishandiso zveKushanda | Kirasi yeKuchera-Kugaya-Kugaya | Mota yeKutama Yakanaka

1. Mashandisirwo

Ichishandiswa nesimba re hydraulic pressure, PDM inofambisa gungano rekuboorera pasi richitenderera, zvichiita kuti mabasa akadai sekuboorera, kugaya, uye kutsausa nzira.

2. Chimiro

PDM inonyanya kuve nechikamu chepamusoro,vharuvhu yekupfuura, stator, rotor, coupling, water passage sub, bearing assembly, drive shaft, uye bottom sub.

3. Nheyo yekushanda

PDM inoshandura simba remvura ine simba rakawanda kuita simba remagetsi kuburikidza nekubatana kwerotor ne stator. Mvura ine simba rakawanda inopinda mumakamuri akavharwa akagadzirwa pakati pe rotor ne stator. Kusiyana kwekumanikidzwa kunoita kuti rotor itendeuke ne spiral channel ye stator. Rotor inotenderera nenzira inoshamisa kutenderedza stator's axis, uku ichitenderera panguva imwe chete newachi pa axis yayo, ichifambisa drill bit rotation.

4. Magadzirirwo ehunyanzvi

Muyero unoshanda: SY/T 5383 Positive Displacement Motor

Muenzaniso wetsanangudzo

mienzaniso:

• 9LZ95×7.0 : Dhayamita yekunze 95 mm, 9/10 lobe ratio hydraulic motor, bit nozzle pressure drop 7 MPa.
• 5LZ165×7.0Ⅱ : Dhayamita yekunze 165 mm, 5/6 lobe ratio hydraulic motor, bit nozzle pressure drop 7.0 MPa, second design modification ye straight-body PDM.
• 5LZ197×7.0-SWFG: Dhayamita yekunze 197 mm, mota ye hydraulic ine chiyero che 5/6 lobe ratio, imba yakakombama kaviri ine stabilizer, rotor isina chinhu ine flow diversion, tembiricha yepamusoro yekushanda 150°C, bit nozzle pressure drop 7.0 MPa.

5. Maitiro Ekushanda

(1) Unganidza BHA.

(2) Mhanya zvishoma nezvishoma kusvika pamamita 3–5 pamusoro pehudzamu hwechinangwa, tanga mapombi kuti atenderere uye chenesa tsime. Kumhanya kwe30 m/min kunokurudzirwa. Zadza tambo yekuboorera nemvura yakachena inoyerera pese pamamita 500 ega ega ekupinda.

(3) Kudzikisa zvishoma nezvishoma, wobva watanga kuboora. Kurema pa bit (WOB): 5–15 kN. Mwero wekuyerera: 500–600 L/min.

(4) Bvisa gomba (POOH).

6. Kungwarira

(1) Iva nechokwadi chekuti PDM yepamusoro yakasimbiswa zvakanaka panguva yekuedzwa kwenzvimbo.

(2) Mvura inoyerera inofanira kunge yakachena.

(3) Mvura inodzoka inofanira kuongororwa uye kubviswa.

(4) Musoro wetsime unofanira kunge uine mudziyo unozvivharira wega kudzivirira zvinhu zvidiki kuti zvisawire mutsime.

(5) Chenesai zvakanaka mutsime musati machinja maburi maviri uye mushure mekupedza kuboora.

7. Kugadzirisa uye Kuchengeta

(1) Mushure mekushandisa, bvisa, chenesa, uye ongorora chishandiso. Tsiva chero zvikamu zvakakuvara. Isa mafuta ekuzora pazvinhu zvese panguva yekubatanidzazve.

(2) Paunenge uchichenesa rabha re stator, usashandise utsi kudzivirira kukwegura kwerabha.

(3) Chengeta mudziyo uyu mudura rine mhepo inofefetera zvakanaka. Chengeta tembiricha iri pakati pe10°C ne25°C, hunyoro husingapfuure 85%. Dzivisa chiedza chezuva chakananga nemvura.
