济阳坳陷潜山储层以溶蚀孔、洞和裂缝为主,储层的发育程度是影响产能的主要因素。本文以CB30潜山为例,对潜山岩溶、裂缝的发育特征进行了研究、描述,根据岩芯观察、测井曲线特征,总结了中强岩溶、裂缝较发育层段测井和录井响应特征,解释了7个溶蚀或裂缝发育储集层段。并对潜山储层的分布规律、控制因素进行了论述。
The buried hill reservoirs in Jiyang Depression are dominated by dissolution pores, holes and cracks, and the degree of reservoir development is the major factor affecting productivity. In this paper, the CB30 buried hill is taken as an example to study and describe the development characteristics of karst and fractures in the buried hill. According to the characteristics of core observation and well logging, the paper summarizes well logging and well logging response Feature, explaining seven dissolution or fracture development reservoir segments. The distribution and control of buried hill reservoirs are discussed.
