【摘要】 在松辽盆地南部,随着勘探的深入和技术的发展,勘探与开发的目标重点已经由寻找构造、断块型油气藏逐渐转移至以岩性因素起主导作用的复杂油气藏,这些带有隐蔽性的油气藏大多数都具备小特征大难题的特点,其中古河道做为良好的油气储集体,其物性好、产能高的特点成为岩性勘探的首选目标。但受地震资料分辨率、信噪比、保真度以及埋藏深度的影响,以及储层纵横向变化快、与围岩阻抗差异小等实际地质问题的限制,古河道的识别始终是地震资料解释中的难点。我们选择作为今后储量接替重要区域的长春岭地区来开展古河道识别技术攻关,应用地震属性分析、分频扫描、参数反演、波形分类、可视化雕刻等多种储层预测技术手段联合作业,突破以往只能定性预测而不能定量识别古河道地震资料解释的瓶颈问题,精确预测和有效识别主力储层分布规律,特别是精细刻画该区泉四段古河道空间展布特征,为高效开发动用这部分储量提供地质依据。同时,对古河道识别方法进行仔细研究和筛选,探索出适合于吉林探区古河道识别方法的工作流程。为其他地区的开发产能建设、勘探井位部署提供技术服务。更多还原

【Abstract】 In the south of SongLiao basin, with the deeply development of oil-gas exploration and the improving of its technology, the target point of oil-gas exploration and development has transferred from the structural and fault hydrocarbon trap to the lithologic occupies the predominant function complicated hydrocarbon trap . These subtle reservoir have the characteristic of "low magnitude. little fault and thin sand " mostly, among them, the old channel as a good reservoir has been an optimized target which is characterized by good physical properties and high productivity. But the channel identification is still difficult in seismic data interpretation for the limitation of resolution, signal-to-noise ratio, fidelity and the influence of burial depth, vertical-horizonal variation of reservoir and the small difference between reservoir and host rock, etc. We have practiced technique research of the old channel identification in Chang Chun ling area of JinLin oilfield’ important reserves, by integrating such as Attribute analysis, Frequency scan, Parameter inversion, Wave classification, Visibility detection, etc. reservoir prediction technologies, break the former a bottleneck for can settling sex predicting but can’t fixed amount identifying ancient course of problem of the old channel identification in seismic data interpretation, Fine predict reservoir distribution regulation, especially the old channel in q4 layer of Chang Chunling area. for developping to use efficiently this part oil-gas reserves the deal provides the geology according to. At the same time, we offers the applicable flows of old channel identifacation in Jilin prospecting area which is contributed to development productivity and well location deployment.更多还原
