A NEW METHOD FOR WATER SOLUBLE GAS RECOGNITION BASED ON COMPREHENSIVE LOGGING: TAKING GUSHI SAG AS AN EXAMPLE
-
摘要: 对渭河盆地第三系张家坡组砂岩储层的影响因素及造成气水层判别困难的原因进行深入的分析研究,在此基础上,结合气测录井资料,利用孔隙度重叠对比法、孔隙度差值及比值法(空隙参数法)和综合测井的补偿中子与补偿密度曲线对比分析法、TNIS成像测井法等,建立了一套适合于本地区的综合识别气水层的方法和标准。对研究区28个层段进行分析研究,并与实际生产进行对比后得出,其符合率达90%,验证了该方法在本区的应用效果,对其他盆地水溶气藏勘探和开发起到借鉴和指导作用。Abstract: Based on the deep analysis and research on the difficulties of identifying water-soluble methane gas reservoir in Tertiary Zhangjiapo Formation sandstone reservoir in Weihe Basin, combined gas logging data, the article was written to solve the difficulties of identification and interpretation about gas-and water-bearing layers, and to provide better services for exploitation of water-soluble gas unconventional new energy exploration. The authors established a set of standards such as porosity overlapping contrast method, porosity difference and ratio (porosity parameter method), and contrastive analysis between compensation neutron and compensated density curves which are suitable in the study area and the TNIS imaging logging to recognize integratedly gas-and water-bearing layers. The standards have been used in the twenty-eight sections in the study area. And compared with the practical production, the compliance rate was 90%, indicating application effect of this method was good. The method may provide reference and guidance for exploration and development of other water-soluble gas basin.
