Process Description:

The integrated process of cementing slip-jacket can realise the integrated operation of cementing, sectional modification of a trip of tubing column, which can realise continuous operation and greatly save the operation time. At the same time, it does not change the cementing operation procedure, ensuring the consistency of the process.

Features:

● Before cementing, the centering device is opened to centre the casing and improve the quality of cementing. 

● During the cementing process, the casing is centred to improve the quality of cementing.

● During cementing process, the use of reducer plugs makes the cementing operation simple and reliable.

● Directly open and open the toe slide to complete the first section of the target layer fracturing, simple operation.

● Pitching and opening the cementing pitching slips to complete the fracturing task in sections, which is simple and reliable; 

● After the fracturing is completed, the cementing slips are opened to complete the fracturing task in the first section.

● After the fracturing is completed, the cementing and fracturing integrated tubing string can realise the regimental diameter, which can guarantee the production of oil and gas in the wellbore with five obstacles.
