Symmetric Casing Systems nrog tis

•  
• Daim Ntawv Thov Ntau

Nws yog tsim rau drilling nyob rau hauv qhov chaw pob zeb tsim yog overburden thiab xav tau casing raj los txhawb

• Qhov zoo tshaj plaws

Cov qauv yooj yim, kev ua haujlwm yooj yim, txhim khu kev qha zoo, cov cuab yeej drilling rov qab tau, thiab lub neej ua haujlwm ntev.

• Cov qauv sib txawv

Concentric system nrog lub nplhaib khoom, nrog tis thiab nrog blocks.

• Cov txheej txheem ua haujlwm
• 
• 1. Thaum lub drilling pib, lub tis viav vias tawm, thiab reams tsav lub casing khau thiab hlab rau hauv lub qhov.
• 2. Thaum tiav qhov drilling hauv cov pob zeb overburden, thim rov qab cov cuab yeej drilling thiab cov tis yuav raug kaw, thiab cov cuab yeej drilling tuaj yeem raug tsa los ntawm lub qhov.
• 3. Kev tsim kho tom ntej tuaj yeem ua raws.
