振幅随偏移距变化技术在高邮凹陷永安-联盟庄地区岩性油藏预测中的应用
|
摘要
针对永安-联盟庄地区构造复杂、地层可对比性差、勘探难度较大的问题,以戴南组二段的E2d52亚段为例,首先对研究区进行测井数据的岩石物理分析,确定该区目的层段的敏感参数;然后,以该区宽方位采集的叠前地震数据为基础进行振幅随偏移距变化(amplitude uersus offset,AVO)模型正演,分析已知油、水和岩性及其不同组合条件下的AVO特征,并判断该区为第一类AVO特征;最后以2口井为约束进行AVO叠前反演,得到一系列的AVO属性,结合之前的研究结果,优选PG属性和敏感因子F属性对目的层段进行有利区域的预测。结果显示,E2d52层段有利区域主要集中在该区北东方及南西方,大多数有利区域靠近汉留断层一带,储层具有厚度薄、横向连续性差的特点。该结果的提出希望为将来勘探开发工作提供借鉴。
In order to solve the problem that the interval of Yong'an-Lian Mengzhuang area is complex,the stratigraphic contrast can be comparatively poor,and the exploration is difficult,taking the segment of E2d52 as an example,based on the prestack seismic data collected in this area,the petrophysical analysis of the logging data of the target interval is used to determine the sensitive parameters. And then the AVO model forward and judge the first type of AVO features was take. Finally,AVO pre-stack inversion is carried out with two wells as constrains,and a series of lithological parameters are obtained. The AVO product attribute and the sensitivity factor F attribute are used to predict the favorable reservoir. The results show that the favorable reservoirs in the segment of E2d52 mainly focus on the northeast and southwest of the area,and most of the reservoirs are close to the Hanli fault. The results of the proposed hope for future exploration and development work to provide reference.
