【摘要】：火成岩作为一种特殊储层,已成为辽河盆地重要的勘探目标之一,但由于火成岩作为储层时,其储集空间类型繁多、孔隙结构复杂且非均质性强,给本文的研究工作带来了很大的困难。本文以辽河东部凹陷红星地区最新采集的两宽一高(宽方位、宽频带、高密度)地震资料为基础,由合成地震记录将地震和测井资料结合起来,进行地震层位标定。运用层序地层学、油气地质学和构造地质学等理论知识,对红星地区沙三中段地层进行地震资料综合解释。通过对区域不同旋回期次界面的追踪识别以及相干体辅助断层的识别建立等时地层格架。通过地震层序理念的引入,将该区沙三中段火成岩内部细分为两大旋回四小期次,并落实了各旋回期次相应的构造特征;以此为基础,采用波形聚类、属性分析等多种技术手段,分期次识别火成岩岩性和岩相,落实工区内火成岩岩性和岩相的分布;同时,针对火成岩的特殊情况,开发重构出能够反映储层物性的优势储层预测曲线,将该曲线应用到地质统计学反演中,预测出优势储层体,识别出最优储层;最后综合叠前OVT域技术和叠后曲率分析技术预测了火成岩裂缝发育区。在综合分析基础上,将优选出的目标区火成岩储层划分为Ⅰ、Ⅱ、Ⅲ类。
[Abstract]:Igneous rock, as a special reservoir, has become one of the important exploration targets in Liaohe Basin. However, when igneous rock is used as reservoir, its reservoir space is various, pore structure is complex and heterogeneity is strong. It brings great difficulties to the research work of this paper. Based on the newly collected seismic data of two widths and one height (wide azimuth, wide band, high density) in Hongxing area of the eastern depression of Liaohe River, the seismic horizon is calibrated by combining seismic and logging data with synthetic seismic records. Based on the theoretical knowledge of sequence stratigraphy, oil and gas geology and structural geology, the seismic data of the middle section of Sha3 in Hongxing area are interpreted comprehensively. The isochronous stratigraphic framework is established by tracing and identifying the sub-interfaces of different cycles and the identification of coherent void-assisted faults. By introducing the idea of seismic sequence, the igneous rocks in the middle part of the third member of the Shahejie area are subdivided into two cycles and four stages, and the corresponding structural characteristics of each cycle are implemented, and on this basis, waveform clustering is used. Attribute analysis and other technical means to identify igneous lithology and lithofacies by stages, to implement the distribution of igneous lithology and lithofacies in the working area, and to aim at the special circumstances of igneous rocks, The predominance reservoir prediction curve, which can reflect reservoir physical properties, is reconstructed and applied to geostatistical inversion to predict the superior reservoir body and identify the optimal reservoir. Finally, the prestack OVT domain technique and poststack curvature analysis technique are used to predict the fracture development area of igneous rocks. On the basis of comprehensive analysis, the selected igneous reservoirs in the target area are divided into class 鈪，
