多分量地震资料预测松辽盆地兴城地区深层火山岩与有利含气带
摘要
松辽盆地断陷期天然气有利带预测是扩大该盆地勘探领域的一个重要组成部分.为在油气资源基地松辽盆地开展大范围深层油气预测,选择徐家围子断陷内局部构造—升平-兴城构造进行地面三分量地震勘探,得到一个可行的预测方案.在深探井控制下,利用三分量地震资料,进行P波、P-SV波层位标定、震相对比,得到研究工区断陷期火山岩分布的局部预测;经过目标层段振幅比、频率比等物性参数的计算对比,得到该工区断陷期营城组有利含气区预测.进一步分析了研究工区区域构造对断陷期地层的控制作用.从烃源岩种类、成熟程度以及火山岩储层性能几方面综合分析,认为在更大范围内存在深层有利含气区带是可能的.最后指出在深层有利含气区带预测中采用三维三分量技术的必要性,以及无井控预测的基本方法,包括构造特征、地层特征预测知识的延用,多参数特征间相似性和综合比较等.
It is an important part of increasing the exploration prospect area in the basin to predict the deep favorable gas zone in Songliao Basin during the fault period.In order to carry out large-range oil and gas prediction in Songliao Basin as the oil and gas resource base,Shengping-Xingcheng structure within the Xujiaweizi faulting depression is chosen to perform the ground three-component seismic exploration,and obtain a feasible predicting project.Under the constraints of the geologic data from deep exploratory wells,using the three-component seismic data,the P-wave and P-SV wave layer calibration,and seismic phase correlation,the prediction of distribution of volcanic rocks in the fault period was gained in the research area;then after calculation and comparison of the parameters of physical properties such as the amplitude ratio and frequency ratio,the favorable predicting zone of Yingcheng formation in fault-zone was obtained. The controlling effect of the regional structures on the fault-depression formation was further analyzed.Synthesizing the analyses of hydrocarbon source rock types,level of maturity and volcanic reservoir performance,a greater extent of the deep gas-bearing zone was considered possible.Finally it is suggested that three-dimension and three-component seismic technology is necessary to predict the deep gas-zone,and the basic methods without control wells include extended application of predictable knowledge on the structure,stratigraphic features,the comparability of multi-parameter characteristics and integrated comparison.
