摘要
杭锦旗地区二叠系下石盒子组具有岩性复杂、储层物性差及气水识别难的问题,为了解决这些难题,将现有9口井的自然伽马能谱测井曲线应用于储层划分和物性判断、岩性识别以及储层含气性判别中得到了很好的效果,并归纳总结出了自然伽马能谱测井识别气水层的判别标准。自然伽马能谱测井在该地区的成功应用为正确评价杭锦旗地区致密砂岩储层提供了可靠的信息。
The lower Shihezi formation of Permian in Hangjinqi area has the problems with complex lithology,poor reservoir properties and gas water identification. In order to solve these problems,this paper applies the natural gamma spectral logging curves of the existing nine wells to reservoir classification, property judgment, lithologic and gas-bearing identiii- cation,which obtained a very good effect. In addition,it summarizes the criteria of gas and water layer identification of natural gamma spectral log. The successful application of natural gamma ray spectrometry logging to the region can provide reliable information for correctly evaluating tight sandstone reservoir in Hangjinqi area.
