Self-Developed Rotary Steering-CG-Steer
The Drilling and Production Institute has successfully developed th e CG STEER rotary steering drilling system with independent intellectual property rights in view of the urgent need for the development of unconventional resources such as shale gas and tight gas in China. CG has completed more than 150 wells in Sichuan-Chongqing shale gas, tight gas, conventional gas, Xinjiang shale oil, Changqing tight gas, Jilin shale oil and overseas Central Asia, with a total footage of more than 170,000 meters.
Precise Pressure Control Drilling Technology(MPD)
The rotary BOP is miniaturized, low in height, and convenient for installation. The serial circulating cooling structure design ensures the sealing reliability of the equipment and prolongs the service life of the assembly.
The pressure automatic control system (electric control) is designed with a single-blade double-inlet structure, which has the functions of automatic control and remote control, and the pressure level is 14 MPa. During pressure control operation, the throttling accuracy of ±0.1 MPa can be realized, which can meet the requirements of automatic control and compensation of wellhead pressure in drilling and cementing.
The new plunger throttle valve is erosion resistant and has a long service life.
The dynamic balance pressure cementing simulation analysis and control software can realize the optimization design of slurry column structure and the real - time dynamic control of annular pressure in cementing, displacement and wait - on - cement stages, and the simulation accuracy is greater than or equal to 95%.
Coring Technology
After more than 50 years of development, "Sichuan-style" coring technology has formed "Three Conventional +Nine Featured" coring technology, which has the ability of "where the drill hits is where the core can be taken ", and the company integrates design, research and development, production and processing, and on-site service. Become the most perfect professional coring service team with the most comprehensive strength in the domestic industrial chain; The unique Sichuan-style coring technology has a market share of more than 80% in China.
Oil-Based Cuttings Thermal Desorption Treatment Technology
Aiming at the problem of high transportation risk in the disposal of oil-based cuttings in remote exploration wells in shale gas development, a thermal desorption treatment device for oil-based cuttings while drilling is developed, which adopts "grinding" internal heating technology, heats uniformly, recovers high oil quality, and the oil content of the residue after treatment is less than 0.35%. It is not identified as hazardous waste by a third party and can be used according to DB51/T 2850-2021. The unit completed the treatment of oil-based cuttings while drilling in two wells on Wei202-H23 platform, with a cumulative treatment of 1125 tons of oil-based cuttings, and all the recovered fluids were used to re-prepare oil-based mud. The processing mode of oil-based cuttings while drilling is established.
Downhole Tools
