辽河盆地及其外围盆地在漫长的地质历史时期形成了浊积扇、河流相、扇三角洲等多种类型的砂体,单层砂体较薄.为了准确地部署井位,应用井约束反演,地震属性分析和分频分析等技术,对不同类型的薄层砂体及含气砂层进行了预测,较准确地刻画了薄砂层的分布及形态,为部署井位提供了依据.经钻探,预测比较准确,效果良好.

The turbidite fan,channel sand and the fan delta in the Liaohe basin and its outside basins in the long geologic history time are thin.In order to locate accurately the position of the well,we applied the log restraint inversion,seismic attribute analysis and frequency division analysis to predict the distribution and the shape of the different thin sand and the gas-bearing sand.We have carried out tests by drilling and obtained good results.
