摘要
以苏里格气田苏76区块三维地震区为例,综合应用地震属性提取及分析技术,结合地质、测录井等多种资料,在层位精细标定和构造精细解释的基础上,提取40多种地震属性,从中优选出与研究目标有关的最敏感的均方根振幅、平均瞬时频率、最大波峰振幅、总能量4种地震属性,并依据这4种地震属性的分布特征,对储集层的平面分布特征进行了描述。在此基础上,结合实钻井的动、静态资料进行综合分析,认为S 55、S 76-6、S 76-18等井区的强振幅、低频反射区为有利储集层发育带。
Taking 3Dseismic area of Su-76 block in Sulige gas field as an example,integrating seismic attribute extraction and analysis techniques,combining with geological,wireline logging,mud logging and other data,based on the fine calibration on layers and the fine interpretation on structures,more than40 seismic attributes were extracted,among them,four seismic attributes that were related to the research targets were preferred,they are the most sensitive RMS amplitude,the average instantaneous frequency,the maximum peak amplitude and the total energy,and distribution characteristics on reservoir plane are described based on the distribution characteristics of these four seismic attributes.On this basis,combined with dynamic and static data of the practical drilling wells to conduct comprehensive analysis,the authors believed that the high amplitude,low-frequency reflection area in wells S 55,S 76-6,S 76-18,etc.,are the favorable belts for reservoir development.
