惠民凹陷商河地区沙一段火山岩储层成因及分布
|
摘要
通过岩心及测井资料的综合分析,总结了火成岩各种岩性在测井曲线上的响应规律和岩性的测井识别标准。在总结火成岩与正常沉积岩测井响应差异的基础上,对商河地区沙一段火山活动的期次、活动类型进行了分析。研究认为该地区沙一段火山活动可以分为6期,属浅水水下喷发。在此基础上,综合利用相干数据体、三维地震资料的时间切片及测井资料解释,研究了各期次火山岩分布,总结出火山岩分布模式及有利储集相带,认为近火山口、远火山口亚相是有利储集相带,为该区火山岩储层油气勘探提供了必要的地质依据。
By analyzing synthetically the core and logging data,this paper summarizes the response law of igneous rocks in logging curve and the logging idebtification criterion of lithology.On basis of the logging difference between the igneous and sedimentary rocks,the times and types of volcanic activity of the first member of Shahejie Formation in Shanghe Region are analyzed.It is considered that the volcanic activity can be divided into six phases in the first member of Shahejie Formation in Shanghe Region,belonging to underwater eruptions in shallow water.On this basis,this paper studies the distribution of volcanic rock in each period,summarizes the distribution mode and advantageous reservoir facies belt by synthetically using the time slice of coherent data volumes,3D seismic data and logging data interpretation.The subfacies of near and far volcanic vents are considered to be favorable reservoir facies belt,which provides the necessary geology basis for oil and gas exploration of volcanic reservoir in Shanghe Region.
