摘要:
时频电磁法具有激发信号强、探测深度大、精度高的特点, 可以通过探测油气藏的电和电化学异常确定含油气状况, 是精细识别火成岩储层目标并进行地面油气检测技术中最有潜力的方法之一. 通过统计辽河盆地中HX凹陷电测井资料, 证实了时频电磁法具备识别不同火成岩的物性基础. 井震-时频电磁联合反演落实了断裂-构造特征, 对沙河街组火成岩内幕刻画更清晰, 共识别出沙河街组内幕沙三段5期火山活动. 通过提取与电阻率和极化率相关的振幅和相位异常, 对比已知钻井出油情况, 总结出了一套极化率评价的分级标准. 结合地震资料, 运用时频电磁法, 反推HX凹陷油气运移机制. 通过研究获得了该区油气评价模板. 根据这一模板在该地区识别出多个油气有利区, 并经后续钻探证实. 该方法可为类似地区油气评价提供借鉴.
Abstract:Time-frequency electromagnetic method(TFEM), characterized by strong excitation signal, large detection depth and high precision, is one of the most promising techniques for the fine identification of igneous rock reservoirs and surface oil-gas detection, which can determine the oil-gas content by detecting the electrical and electrochemical anomalies of oil-gas reservoirs. Through analyzing the electrical logging data of HX sag in Liaohe Basin, it is confirmed that TFEM has the physical basis to identify different igneous rocks. The fault structure characteristics as well as the igneous rock inner structures of Shahejie Formation are obtained by the well seismic-TFEM joint inversion, and 5 stages of volcanic activities within the third member of Shahejie Formation are identified. A set of classification standard for polarizability evaluation is summarized through the extraction of amplitude and phase anomalies related to resistivity and polarizability, and comparison of oil production condition of the known wells. Combined with the seismic data, the oil-gas migration mechanism in HX sag is reversed by TFEM. The oil-gas evaluation template in the area is obtained through the research, by which several oil-gas favorable areas are identified and verified by subsequent drilling work. The method can provide reference for oil-gas evaluation in similar areas.
