The Logging Evaluation Method of Carbonate Reservoir in the YD Oifield
-
摘要: 为提高碳酸盐岩储层测井参数的准确性,利用地质、岩心和试油资料,根据YD油田主要储层的岩电特征,采用正逆累积统计方法、油气累计体积以及Pickett交会图方法,更新了储层岩石、矿物、孔隙度、渗透率和饱和度解释模型,细化了各个层系的孔渗饱解释参数,特别是每个参数的截止值.根据最新的解释参数,重新建立了储层划分类型和解释标准;并在此基础上,利用SFT测试资料对所有目标层系重新划分了油水系统.油田实际生产测试表明,碳酸盐岩储层测井评价方法能够指导碳酸盐岩的测井综合评价、油藏储量计算和油气实际生产.Abstract: In order to improve the logging accuracy of reservoir parameters, based on the geologic, core and well test data and rock-electrical characteristics of main reservoirs in the YD Oilfield, the positive and negative accumulation statistics method, oil and gas accumulation volume method and Pickett crossplot method were used to update the models of reservoir rock, mineral, porosity, permeability and saturation. The interpretation parameters of porosity, permeability and saturation in each zone were refined, especially for the cutoff value.The reservoir division and interpretation standards were rebuilt according to the latest parameters,and on this basis, the oil-water system in all target zones were redivided according to the SFT data. Well testing showed that the logging evaluation methods can be used to guide the comprehensive logging evaluation, reserve calculation and actual production in carbonate reservoir.
