Measurement and adjustment of underground intelligent injection in Qinghai Oilfield
As of February 1st, the Qinghai oil field has completed 4 wells with self-developed underground intelligent injection technology. Field continuous testing and tracking data show that the downhole data transmission is efficient and accurate, and the ground control is fast and reliable, marking the significant progress of intelligent separate injection technology in Qinghai oilfield.
Qinghai oilfield has 60 years of exploration and development, some oil field has entered the middle and late stages of development, low formation pressure and insufficient fluid supply, wells, wells, wells with high water, shut down wells increasing year by year. The existing multi-layer separate injection technology has been unable to meet the needs of "enough water, water injection, fine water injection and effective water injection" because of the long time of occupying well and the ineffective effect of stratified water injection.
In order to solve the problem of water injection well test to be repeated under existing instruments, the number of cast fishing, long test cycle, low efficiency and easy resistance and sticking problems of Qinghai oilfield research following the formation of separate injection concentric bridge after the fourth generation of injection technology, intelligent downhole separate injection technology. After the application of this technology, the qualification rate of the adjustment is 100%, which realizes the functions of real-time admission of stratified flow and pressure data and the adjustment of layered distribution.
"It takes 2 to 3 days to complete the adjustment operation by the conventional process. The underground intelligent injection technology realizes the adjustment of the adjustment, and it takes only 1 hours to complete it." Yuan Yongwen, director of the oil production technology research institute of Qinghai drilling and Mining Technology Research Institute, said.
