ABSTRACT: Low permeability reservoirs are the main object of future oil and gas exploration and development in China. To achieve the efficient development of low-permeability reservoirs, the classification, geological and development characteristics and main exploitation technology are systematically analyzed by comparing and analyzing the development characteristics of 68 low-permeability sandstone oil fields at home and abroad. At the same time, starting from the analysis of reservoir damage caused by minerals and crystalline salts in low-permeability reservoirs, this paper summarizes and analyzes the resistance reduction and increased injection characteristics of common formation modification, formation surface modification, and supporting drilling and completion technology. And the design and development of plugging + resistance reduction of surface modification is put forward for resistance reduction and increased injection technology, It provides a basis for the subsequent efficient replenishment of formation energy and greatly enhanced oil recovery in the low permeability reservoirs.
