储层构造裂缝预测研究

Research on the forecast of reservoir structural fractures

储层构造裂缝预测是低渗透油藏研究的主要内容之一,通过大量的文献调研,对构造裂缝预测研究的现状、难点、影响因素和发展趋势进行了总结。储层构造裂缝预测研究的难点为裂缝的空间分布和参数定量表征,主要影响因素是现今地应力和构造活动,今后的重点研究内容是加强构造裂缝的形成机制研究、提高其分布规律及数值模拟的准确性等。

Reservoir structural fractures forecast is one of the main research contents of the low permeability oil reservoir. The researching present, difficult points, influencing factors and development tendency of the structural fractures were summarized based on comprehensive investigation and analysis. The spatial distribution and the quantitative characterization with parameters of the fractures are the difficult points in the structural fractures forecast. The present ground stress and structural activity are the key factors affecting the fractures forecast. The research about forming mechanism and the improvement in accuracy of distribution and numerical simulation of the structural fractures will be the most important content in future.
