以三塘湖盆地牛东区块石炭系卡拉岗组火山岩储集层测井评价为例,应用测井和试油试采资料,结合钻井取心、综合录井和实验分析数据等资料,阐述了用常规测井方法评价火山岩储集层的基本原理及方法,确定了火山岩岩性识别标准;通过对火山岩储集层孔隙度、渗透率、含油饱和度研究以及对试油和试采层应用交会图法,确定了该地区有效储集层的下限标准。实际应用表明,用测井参数建立的火山岩储集层解释模型可以用于该区块火山岩储集层的定量评价。在提高岩性识别精度的基础上,利用测井资料可以有效预测火山岩储集层物性及含油气性,该方法为牛东区块探明储量计算提供了依据,有效指导了该地区的勘探生产。
Taking Logging evaluation of Volcanic reservoir of Carboniferous Karakang Formation in Niudong section of Santanghu Basin as an example, this paper expounds the well logging data of oil and gas reservoir by well logging and oil testing, combined with drilling coring, comprehensive logging and experimental analysis data The basic principles and methods of volcanic reservoirs evaluation by conventional well logging methods and identification standard of volcanic lithology have been established. The porosity, permeability, oil saturation of volcanic reservoirs and the intersection of oil and test beds Figure method, to determine the effective reservoir of the lower limit of the standard. The practical application shows that the interpretation model of volcanic reservoirs established by logging parameters can be used for the quantitative evaluation of volcanic reservoirs in this block. On the basis of improving the accuracy of lithology identification, logging data can effectively predict the physical properties and hydrocarbon-bearing properties of volcanic reservoirs. This method provides the basis for the calculation of proven reserves in Niudong block and effectively guides the exploration and production in this area.
