摘要
裂缝和溶蚀孔洞是塔河油田奥陶系碳酸盐岩的主要储渗空间,对碳酸盐岩裂缝与岩溶发育规律的研究具有重要的意义.在分析本区地质演化特征的基础上,利用不同岩溶相带在测井曲线上的不同反映,初步分析并总结了中上奥陶统尖灭线以南及以北下奥陶统岩溶发育带的测井响应特征.
Fractures and caves are the main porosity types in Ordovician carbonate reservoirs in Tahe Oilfield. Thus, it will be of very important theoretical and actual significance to study the their formation history. On the basis of the reasearch to the geological evolution history of the studied area, we analysed the different respondences of logging data corresponding to different kinds of carst phases in the studied area, and summarized the general characteristics of the respondences of logging data corresponding to carst phases in middle-upper Ordovician south of the finger-out line and lower Ordovician carst phases in the north.
