川西坳陷是四川盆地油气勘探的重点,而须家河组二段又是该区域重要的储层。该储层具有非均质性强、致密化程度高的特点,裂缝发育情况对油气勘探具有决定性作用。通过对分形技术的原理、方法的介绍,并利用该方法对须二段储层的裂缝进行预测。结果表明,油气藏的存在与否与裂缝发育和盖层发育两个因素直接相关。研究区内须二段储层大部分属于裂缝发育区,对油气勘探很有利。
The western Sichuan depression is the focus of oil and gas exploration in the Sichuan Basin, and the second member of the Xujiahe Formation is an important reservoir in the area. The reservoir has the characteristics of high heterogeneity and high degree of densification. The development of fractures is decisive for oil and gas exploration. Through the introduction of the principle and method of fractal technology, and by using this method, the fractures in Xu 2 reservoir are predicted. The results show that the existence of the reservoir is directly related to the development of fractures and the development of the caprock. Most of the second member of the second member of the study area belongs to the zone of fracture development, which is very favorable for oil and gas exploration.
