摘要
Abstract
The reservoirs of Xujiahe Formation in Dayi area are super tight sandstone reservoir, and the reservoir petrophysical property is poor. The existence of fractures greatly improves the reservoir permeator. There are tectonic fractures, diagenetic fractures and abnormal high-pressure fractures in this area. There exists drilling induced fractures in some wells. Tectonic fractures develop well among them, which is the key types of factures. The tectonic fractures of this area mainly take the form of low-angle and high-angle fractures. The distribution of fractures development is controlled obviously by faults. Fracture-developed zone presents zebraic distribution along east-north fault belt, where faults clip zone as well as the fracture in high-steep part of structure develop better. The controlling factors of the fractures development mainly include tectonic stress, tectonic position, rock types, rock stratum, etc. The tectonic position and rock types are the key factors controlling the development and distribution of the fractures.关键词
