Development Characteristics and Development Technology Analysis of Low Permeability Oilfield

Abstract

Abstract Oil is an important energy resource in the world. Therefore, the oil extraction efficiency will affect the social and economic development of our country, which requires us to constantly improve our own extraction technology and improve the efficiency of oil development. Although China is a country with abundant oil reserves, most of the oilfields in China are low permeability ones. There are many problems in Low permeability oilfield (hereinafter referred to as LPO), such as small porosity, low permeability, difficult production and so on. Therefore, this paper first analyzes the characteristics of LPO, such as low natural productivity, poor water absorption capacity, rapid decline after fracturing. Therefore, China has made more research on LPO, which has formed a relatively complete series of LPO production technology. Finally, this paper summarizes the current development technology of LPO in China, which will realize the economic and effective development of LPO.
