将高分辨率层序地层学和地震储层预测技术有机结合,并充分发挥这2种技术的优势,可为岩性地层油气藏勘探研究提供行之有效的方案。在高柳地区东营组岩性地层油藏勘探中应用了该方法。首先以多级次基准面旋回为参照面进行高分辨率层序地层研究,建立研究区层序地层划分方案和层序地层格架,将东营组划分为1个二级层序,并进一步划分出4个三级层序;然后应用高分辨率地震资料,在高分辨率层序地层格架约束下,采用储层地震反演技术,追踪识别4个层序旋回内的有效砂体(砂层组)共28个,为研究区岩性地层油气藏勘探提供了有利的决策依据。
The organic combination of high resolution sequence stratigraphy and seismic reservoir prediction technology and giving full play to the advantages of these two technologies can provide effective solutions for the exploration and study of the lithologic stratigraphic reservoirs. This method is applied to the exploration of lithologic stratigraphic reservoirs in Dongying Formation in the Gaoliu area. Firstly, multi-level datum cycles are used as reference planes to study high-resolution sequence stratigraphy, and to establish sequence stratigraphic division scheme and sequence stratigraphic framework in the study area. The Dongying Formation is divided into a second-order sequence and further divided Then, using the high-resolution seismic data, under the restriction of high-resolution sequence stratigraphy framework, the reservoir seismic inversion technique is used to track and identify the effective sand bodies (sand Layer) a total of 28, for the study area lithologic reservoir exploration provides a favorable basis for decision-making.
