摘　　要：黄骅凹陷火成岩油藏纵向上产出层系多,横向上分布范围广,岩相、岩性及储集空间极其多样复杂。长期以来,在火成岩油藏的勘探开发中,岩相、岩性的识别,储层类型的划分,油气评价一直是地质家们棘手的问题。针对这些问题,充分发挥测井资料连续性强、分辨率高、井周覆盖面大的特性,研究分析了各种不同岩相、岩性火成岩的测井响应特征,根据这些特征对黄骅凹陷不同类型火成岩储层进行了划分,形成一套利用测井资料评价火成岩的方法。通过应用,表明具有很好的实用价值。Volcanic rock is widely developed both in the vertical and horizon direction in Huanghua depression. Because of the complexity of its lithofacies, lithologies and reservoir spaces, it＇s always difficult to identify the depression for geologists. To solve these questions, we studied the characteristics of log responses to various igneous reservoirs by taking full advantage of well logging data that have good continuity, high resolution and big cover area around the boreholes. Based on those logging responses, the types of the igneous reservoir is identified in Huanghua depression and a method is given which can be used to evaluate the reservoir. File log application shows the method is good and practical.
