| 摘 要： | 在区域地质背景研究及大量文献调研的基础上,结合地质地震资料,通过单井分析及连井对比研究,探讨了研究区古岩溶的形成机理和控制因素、储层的空间发育及岩溶洞穴的充填特征。认为轮古西地区经历多期地壳抬升,奥陶系古潜山发育两期岩溶旋回,纵向上形成了四套与洞穴有关的古岩溶储层,其中第Ⅱ岩溶层主要分布在岩溶斜坡区,洞穴广泛发育,充填程度低且位于构造高部位,是最有利的油气聚集层段。

| Abstract: | Based on the analysis and comparisons of drilled wells,geological and seismic data,it is shown that two phases of karst cycles developed during Ordovician period in the west part of Lungu area,which results in four sets of palaeokarst reservoirs related with caves in vertical.Among them,the second reservoir is mainly distributed in the karst slope so that plenty of caves and pores are developed and have fillings less than those in relatively higher structural locations.The second reservoir is recognized as the most favorable one for hydrocarbon accumulation in this area. |
