cn recently, the Pu 6-180 well deployed and implemented by the Dongpu Development Research Institute of the Zhongyuan Oilfield Exploration and Development Research Institute, after fracturing and commissioning Shasanzhong 4, it produced 11.
5 tons of high-yield oil per day, confirming the extremely low oil flow in the Zhongyuan Oilfield.
Permeable reservoirs can achieve good production results under the conditions of advanced water injection and pressure retention
.
Well Pu 6-180 is a new productivity well deployed in the Pu 84 block in the southwest wing of the Pucheng structure.
According to the overall production plan, a total of 3 water wells and 4 oil wells are deployed in this block.
Well Pu 6-180 is the third.
For the oil well that was successfully put into production, the target interval of Shasanzhong 3-4 encountered a total of 13 layers of 31.
0 meters.
After the fracturing was put into production, the daily oil production was 11.
5 tons, the daily fluid production was 14 tons, and the water cut was 18%
.
The successful commissioning of the three oil wells has further confirmed that the ultra-low permeability reservoirs can be supplemented by advanced water injection through water wells, and the large-scale fracturing of the oil wells can achieve good results, and it has also strengthened the researchers to effectively develop the ultra-low permeability and difficult-to-produce reserves.
Confidence
.
In the next step, this technology will continue to be promoted and applied in the same type of oil reservoirs in Pucheng, Mazhai, Weicheng and other oil fields, and it is estimated that the new recoverable reserves will be 1 million tons
