层序约束地震储层预测技术在高柳地区东营组岩性地层油藏勘探中的应用
|
摘要
将高分辨率层序地层学和地震储集层预测技术进行有机结合,为岩性地层油气藏勘探提供行之有效的方案,并在高柳地区东营组岩性地层油藏勘探中成功应用。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。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个三级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 high resolution sequence stratigraphy was combined with the seismic reservoir prediction techniques to provide a method of lithological reservoir exploration and successfully applied in the reservoir exploration in Gaoliu Area. The multi-grade base-level cycle was used for a high-resolution sequence stratigraphical study to establish a program of sequence stratigraphical division and a sequence stratigraphical framework,by which Dongying formation was divided into one long-time level cycle and four mid-time level cycles. By using the seismic reservoir inversion technique and constraining by the high-resolution sequence stratigraphic framework,twenty individual sandstone in the four sequences are identified,it provides important evidence for the lithological reservoir exploration.
