摘　　要：本文概述了低渗透储层的地质成因特征和孔隙结构特征，以及由地质因素引起的低渗透油田的基本渗流特征。以丘陵油田为例，提出了低渗透油田裂缝和地应力研究的重要性及研究方法。应用数值模拟研究了低渗透油层人工造缝和天然裂缝与井网、注采系统部署的关系，还提出了注水井和采油井对应压裂改造、降低注水水质标准的依据。This paper summarizes the geologic characteristics and the pore structural characteristics of low permeability reservoirs, and generalizes the basic percolation characteristics of low permeability oilfield based on the geologic factors. Taking Qiuling oilfield as an example, discusses the methods of fracture and stress research in low permeability oil field and its importance. Relations between the natural fracture systems, induced fracture systems and well pattern configuration, orientation of the injection-production system are studied by means of numerical simulation. Bases for combined fracturing of injector and producer and lower standard for injection water quality are suggested in this paper also.
