| 摘 要： | 溶洞型储层在塔河油田奥陶系地层中比较常见。文中通过对洞穴在常规测井及成像测井的响应特征的分析研究,建立了塔河油田溶蚀孔洞的测井识别方法,即利用自然伽马与电阻率的交会图,结合常规测井资料和全井眼地层电阻率扫描成像测井,可以评价溶蚀孔洞的发育及充填程度;利用多种不同径向探测深度测井资料的对比,可以评价溶蚀孔洞的径向延伸程度。实例分析表明,利用测井资料识别溶洞的方法是可行的。

| Abstract: | Cave reservoir is common in Ordovician strata of Tahe Oilfield. Based on the analysis of response characteristics of conventional logging and imaging logging of the caves, the identification method of cave has been established in Tahe Oilfield, namely through the use of the cross plot of gamma ray and resistivity combined with conventional logging data and formation scanner log of full hole, the development and filling situation of cave can be evaluated. Through the comparison of logging data of different radial depths, the extension of corrosion caves can be evaluated. Case analysis shows that the identification method of cave using logging data is feasible. |
