河包场地区含油气检测
|
摘要
含油气检测是利用油气层不同于水层或干层的地球物理响应直接识别储集层流体类型的研究。主要方法有地震属性-地质分析、信息分解、多属性优选、多属性综合预测等。河包场地区须家河组砂岩厚度较大,砂地比高,烃源相对不足,储层含水饱和度普遍较高,油气层识别难度大。以钻井油气分布、油田地质情况分析、地震资料为基础,主要运用地震属性提取、多属性综合预测等方法对须二、须四段进行了含油气检测,有效确定了已知油气层含油气范围,预测了有利区,为储量计算、井位部署提供了依据,勘探实际证实该方法在研究区具有一定适用性。
The detection of hydrocarbon potentials is to recognize the fluid type of reservoir directly by using the different seismic response of oil&gas strata from water layers or dry layers.Concrete techniques for hydrocarbon detection include seismic attributes and geological analysis,multiple attributes optimization and prediction by integrating various seismic attributes.The high-quality reservoir is of fracture-porosity reservoir type and is showed as "two lows and one high" in the resistivity logs,making it is very difficult to explore.Based on the analysis of hydrocarbon distribution by drilled wells,geological conditions of the oilfield and seismic data,various techniques,such as seismic attributes extraction,attributes evaluation,comprehensive attributes analysis and plane prediction by multiple attributes,are used to detect hydrocarbon in T3x2 and T3x4(the second and fourth members of Xujiahe formation,Upper trassic) and determine their hydrocarbon distribution,which provides foundation for reserves calculating and well deploying.
