中国东部老油区的油气勘探已进入隐蔽油气藏勘探阶段,隐蔽圈闭勘探的关键是储层识别与描述(主要是砂体的预测)。针对陆相断陷湖盆复杂多样的隐蔽圈闭类型,开发形成了以三维地震勘探技术和地震地质分析技术等为基础、在不同勘探阶段的岩相、岩性、物性及流体预测的配套技术系列,应用于济阳坳陷典型的河道砂体和浊积砂体的识别与描述,取得了良好的勘探效果。

The maturing oil areas in eastern China have entered the exploration stage for subtle traps,in which the recognition and description of reservoir(mainly the prediction of sandbodies)is considered the key factor for successful exploration.Aiming at the various types of continental subtle traps in fault lakes,set of technologies that based on 3-D seismic exploration technology and seismo geological analysis are developed for determination of the facies,lithologies,physical properties of reservoirs,and prediction of fluids at different exploration stages.The application of the technologies in the recognition and description of the typical channel turbidite sandbodies and sandstones in Jiyang depression shows positive results.
