摘要
印度尼西亚A气田整体为一个断块发育、油气水系统分布复杂的凝析气藏,储量计算的难点在于储层油气水层难以准确划分。在进行精细测井解释的基础上,通过分析射孔测试层段已确定的油气水层的测井响应特征,采用三孔隙度差值法与比值法、视水层中子孔隙度测井值法、声波时差差值法、轻/重烃比值法及电缆地层测试法等几种方法,建立了一套适合A气田油气水层定量识别的标准,并取得了较好的应用效果。
Gas Field A was a condensate gas reservoir with the development of fault block and complex distribution of oil,gas and water system.The difficulty in calculating reserves was that it was difficult for identifying the oil,gas and water layers in the reservoirs.Based on the accurate logging interpretation,and analysis of the logging response characteristics of the oil,gas and water layers determined by the perforated test layer,several methods such as three porosity differential method and ratio method,acoustic time difference method,the method of apparent water layer neutron porosity logging,light/heavy hydrocarbon ratio method and wireline formation testing method are used to establish a set of quantitative standards of oil and gas layer identification for Gas Field A and good application effect is achieved.
