摘要
搞清奥灰岩地层裂隙发育带的裂隙分布，进行岩溶水流体预测，对于建矿寻找水源及采煤防水是至关重要的。本文利用振幅保真处理，获得连续性比较好的奥灰岩地层顶界面反射波同相轴，根据Ｂｉｏｔ理论的基本观点，结合地下流体力学理论，利用奥灰岩地层地震资料的振幅、反射系数及层速度等信息，提取奥灰岩地层流体密度等物性参数及流体参数。从而预测奥灰岩溶水的分布范围，为水文钻探找水提供依据。本文利用山西潞安及山东许厂等地区的地震资料，预测了奥灰岩含水地层的流体分布，取得良好的地质效果。
making clearly the crack distribution of crack developing belts in Ordovican limestone,predicting karst flow are important to finding water supply in constructing coal mine and preventing water in mining .In this article,the author gets the good continune reflected wave equidirectional axis of the Ordovician limestone top boundary,using amplitude undistortion processing;gets the physical parameters as flow density and flow parameters of Ordovician limestone stratum,depending on combing the basic points of Biot theory to underground hydromechanism,the amplitude and reflectance and layer rate of Ordoviaian limestone stratum.Consequently,predicting distribution areas of Ordovician limestone karst flow for the evidences of finding water with hydrological drill. In this article,good geological results of predicting flow distribution in the water-bearing strata of Ordovician limestone have been obtained from the seismic information procession of Shanxi Luan and Shandong Xuchang and soon.
