新疆柯坪—巴楚地区碳酸盐岩构造裂缝发育的控制因素及油气勘探意义
The Controlling Factor Study of Development of Carbonatic Rock Fractures in the Kelpin-Bachu Area, Xinjiang and Its Petroleum Exploration Significance
摘要
Abstract
The development degree of fractures is an important aspect of quantitative study on structural fractures in the carbonatic rock area,and is if great important to reservoir prediction of fractured carbonate oil and gas reservoir.Based on the field geological work,the development and distribution of fractures were discussed in terms of lithology,rock bed thickness and structure types.The geological model was proposed according to the different factors controlling the fracture development.The results show that dolomite is subject to produce structural fractures in the same tectonic setting.The thicker the layer,the smaller the fracture density,and the bigger the scale of fractures.The fracture density controlled by strike-slip fault decreases exponentially with increase of the distance,resulting in the formation of so-called fault-controlling fracture zones.The fault-controlling fracture zones are closely related to nature,scale and offsetting distance of the faulting.The ratio (K) of fracture zone width to fault fracture zone is an important parameter for the prediction of fracture zone controlled by fault.关键词
