Dab tsi yog Symmetric Casing System
Symmetric Casing System yog tsim rau kev ua haujlwm drilling xws li lub hauv paus tsev, piling tsim, drilling rau dej qhov dej thiab geothermal zog, tunneling, thiab kab rov tav drilling nyob rau hauv ntau hom av.
Ua ke, lub hauv paus xyaum me ntsis thiab lub tes tsho concentric sab nraum lub chaw xyaum me ntsis hu rau lub pob zeb laum lub qhov, thiab lub tes tsho concentric reaming nkaus maj mam ntxig lub casing rau hauv lub qhov. Lub tes tsho concentric tseem nyob rau hauv lub qhov tom qab qhov nruab nrab laum me ntsis raug tshem tawm thaum nws tau mus txog lub txaj.
Txij li thaum Symmetric Casing System siv concentric tag nrho-lub ntsej muag drilling, qhov kev pheej hmoo ntawm ib tug daig drilling kev huam yuaj yog npaum li cas qis dua nws yuav nrog eccentric los yog yeeb nkab drilling. Tsis tas li ntawd, rauj qhov kev cuam tshuam zoo ntawm qhov zaus tau nce ntau heev, ua rau lub qhov taub me me thiab txo qis Symmetric Casing System tsis kam.
Cov kauj ruam rau Symmetric Casing System:
1. Cov khau thiab cov nplhaib sib dhos ua ke rau lub casing yog welded rau lub casing ua ntej drilling, thiab lub rooj sib txoos ces muab xauv rau hauv cov khoom tsav tsheb nrog rauj pib drilling.
2. Cia lub casing, casing khau, thiab nplhaib cov khoom nyob rau hauv lub qhov tom qab txhim kho lub casing nyob rau hauv lub tsim nyog overburden bedrock. Tsuas yog qhib cov khoom tsav tsheb nrog qhov rov qab tig kom tshem tawm cov hlua tho nrog cov khoom tsav tsheb tshem tawm.
3.Txawm li cas los xij ntawm qhov drilling siv tus qauv laum cov hlua los yog tshem tawm cov casing, casing khau, thiab nplhaib cov khoom rau kev ua haujlwm ntxiv.
