Abstract

Abstract

The Archean crystallization metamorphic rocks are important reservoir rock types in buried hill, and fracture developmental potential for different types of Archean metamorphic rocks have not been yet clearly recognized.Based on a large number of rock mechanics experiments, core fracture observation, imaging logging data, and oil field production practices, the fracture developmental potential for different types of Archean metamorphic rocks has been analyzed.Rock mechanics test results show that the mechanical properties are changable in different Archean lithology, e.g., the brittleness coefficient generally decreases with increase of dark minerals.In addition, rock mechanics parameters are closely related to the loading direction in gneiss which bear well-developed oriented structure.The brittleness coefficient f_b gets greater when the angle between gneissosity and the loading direction changes from less than 45° into greater than 45°.A large number of oil production practice data show that shear fracture is more often seen in the gneiss with oriented structure, while tension fracture in the granulite without oriented structure.According to the comprehensive analysis, the development potential of shear fracture in different rocks can be arranged as:gneiss class > mixed granite class > amphibolite; while that of tension fracture as: mixed granite class, light granulite > gneiss class > amphibolite.
