| 摘 要： | 茅口组储层以生屑灰岩储层为主,储集空间主要为溶孔、裂缝。这里运用P波振幅方位各向异性分析方法,对清溪场构造茅口组储层开展裂缝预测,搞清了裂缝发育与地层岩性以及构造发育之间的关系,明确了裂缝的走向、强度,以及密度发育部位,预测了裂缝的分布范围。实际资料应用表明,用该套方法识别裂缝—溶隙型储层是有效和可靠的,可以检测出有利的裂缝储层发育带。

| Abstract: | Maokou formation is a set of bioclastic limestone reservoirs in which the main type of reservoir space are dominated by dissolution pores and fractures. In this paper, the fractures in Maokou formation of Qingxichang structure has been predicated by analyzing the P wave amplitude anisotropy, and as a result, the relations among fracture development, lithology and structures are clarified. The strikes, intensity and the location of massive fractures are found out and the range of fractures distribution are p... |
