Abstract

CO2 flooding technology in ultra-low permeability reservoir is the key technology in modern oilfield technology development, which plays a key role in oilfield exploitation of ultra-low permeability reservoir. In this paper, CO2 flooding technology for ultra-low permeability reservoir in oilfield is analyzed and studied. The main characteristics of ultra-low permeability reservoir in oilfield are briefly analyzed, and the development of CO2 flooding technology is discussed. At the same time, the application of CO2 flooding technology in ultra-low permeability reservoir of XX Oilfield is studied and summarized.

Highlights

Oil is an important resource used in the development of modern society, and it has a good application in many fields of social production
In its oilfield development technology research, CO2 flooding technology research is an important technology in the region, which plays a key role in oilfield development
In the technical exploitation of the XX oilfield, certain improvements have been made to the CO2 flooding technology currently used in my country

Summary

Introduction

Oil is an important resource used in the development of modern society, and it has a good application in many fields of social production. The increasing demand for modern oil resources leads to the depletion of oil reserves in the modern world. The exploitation of oil resources has entered a more difficult stage. The development of low and medium permeability reservoirs in oil fields is difficult, which has become an urgent problem to be solved in modern oil field exploitation. In the research process of modern oilfield exploitation technology, relevant experts put forward that CO2 flooding technology can improve the development efficiency of ultra-low permeability reservoirs and play a vital role in the comprehensive exploitation of modern petroleum resources
