Are carbon dioxide systems used to improve oil recovery in China’s oil fields? What is the source of the carbon dioxide they use?
There are methods that use carbon dioxide to improve oil recovery; I’ve heard that the Zhongyuan Oilfield has experimented with using carbon dioxide to enhance crude oil recovery.
The Pilot Production Team of the East China Petroleum Bureau has adopted carbon dioxide gas flooding in the block where the Caoshé Joint Station is located, and the source of the carbon dioxide is also from the strata
I’ve only heard that polyacrylamide is used to improve it; I haven’t heard of carbon dioxide being used
The Daqing Oilfield is currently carrying out CO2 enhanced oil recovery pilot injections
The Chunliang Oil Production Plant in the Shengli Oilfield is currently carrying out CO2 enhanced oil recovery pilot tests
Using CO2 to improve recovery rates is an important method for storing CO2, as it can enhance recovery rates while also reducing greenhouse gas emissions
Our Jilin oil field is also working on this, but the cost is very high; due to the need for high-pressure injection, blockages occur frequently in winter, so it doesn’t seem to be very mature yet
