波阻抗反演预测奥陶系灰岩顶部含隔水性
|
摘要
地震反演技术是岩性地震勘探的重要手段之一,其中地震井约束波阻抗反演技术是利用钻孔测井数据高的纵向分辨率,对井旁地震资料进行井约束反演,然后在此基础上对井间地震资料进行反演,推断地层岩性在空间上的变化情况,本文根据新驿煤矿首采区的三维地震和测井资料,利用波阻抗反演技术预测该区奥陶系灰岩顶部的含隔水性,并依据波阻抗值的大小圈定含水层中的可能富水区。
Seismic inversion technique is one of the important means for lithologic seismic exploration.Logging data with high vertical resolution are used to constrain the seismic data nearby wells by well log constrained inversion technique.The seismic data between wells are inversed on the base,and the lithology variation of strata is inferred.3- D seismic and logging data of the first mining area in the Xinyi coal mine are dealt with impedance inversion to predict aquosity and watertightness of the top Ordovician limestone and the possible water-rich areas in the aquifer are determined by the impedance values.
