Shengli Oilfield's CO2 flooding plan was approved
The industrial test plan for carbon dioxide flooding in the Shasi section of the Shasi section of the Shasi section of the high 89-Fan 142 area of Shenglizhuang Oilfield of Shengli Oilfield has been approved
recently.
This is currently Sinopec's largest overall industrial test scheme
for CO2 flooding.
The traditional oilfield development method is water injection flooding, but it is difficult to inject water in ultra-low permeability reservoirs, and the use of carbon dioxide gas flooding can improve the development effect and efficiency
of ultra-low permeability reservoirs.
It is understood that the program deploys 180 wells, including 110 oil wells and 70 gas injection wells, and will build a production capacity position with an annual oil output of 120,000 tons
.
According to the deployment, starting from next year, the block will inject an average of 340,000 tons of carbon dioxide per year in the first three years, and by the end of 2029, it will inject 4.
65 million tons of gas cumulatively, and the carbon dioxide storage rate will reach 62%.
