| 摘 要： | 利用纯岩石体积模型、测井数据回归方法分别计算了不同岩性的骨架参数。使用常规测井资料,给出了王府断陷盆地深部火石岭组火山岩储层孔隙度和渗透率的计算方法。分析了储层物性与岩性、岩相、孔缝和埋深的关系,发现有利储层主要发育在火山口杂岩相内,岩性主要为火山熔岩和火山角砾岩;溶孔和溶蚀缝是主要储集空间;埋深对火成岩储层的发育影响不大。利用储集层品质指数(RQI),定性地对王府气田20口井的火山岩储层物性进行综合评价,评价的结果与试气产能结论符合情况较好。

| Abstract: | By pure volume model and logging data regression methods，the framework parameters of different rock types have been calculated in different methods，respectively． A method was given by using conventional log- ging data to determine the porosity and permeability of volcanic rock reservoirs of Huoshiling Formation in Lishu Fault Depression． This paper presents the relationship among the physical property and lithology，lithofacies，pore- fracture and buried depth，suggesting that the favorable reservoirs are in the crater complex facies composed of vol- canic lavas and breccias． The dominated reservoir spaces are dissolved pore- fractures and the buried depth has lim- ited influence on volcanic rocks． The Ｒeservoir Quality Index (ＲQI) have been applied to evaluate the comprehen- sive physical property of reservoir qualitatively． In order to gain a deep insight into the volcanic reservoirs，we use this method on 20 wells of Wangfu gas field． The results of this evaluation are consistent with the potential of gas test． |
