摘要
淮北矿区煤层下部奥陶系灰岩的问题影响着煤矿的安全生产,如何准确地解释奥陶系灰岩的地质赋存状态是煤矿开采非常关注的问题。通过对奥陶系灰岩的地质特征及其地震响应特征的分析,采用精细的二次处理解释的数据体,基于测井-地震数据体的联合技术,针对缺少钻遇奥陶系灰岩钻孔,通过数学地质的方法,基于三维地震勘探技术准确预测奥陶系灰岩的赋存状态,获得了奥陶系灰岩的地质成果,从而可得到高于传统预测方法。实现了基于三维地震勘探技术预测煤层下部奥陶系灰岩顶界面赋存状态的方法,地质效果较好。
The problems of Ordovician limestone in Huaibei mining area affect the safe production of coal mine,and how to interpret accurately the occurrence of Ordovician limestone is a major concern of coal mining.Through the analysis of the geological characteristics of Ordovician limestone and the characteristics of seismic response,this paper uses the interpretation data of the secondary treatment,aiming at the lack of drilling in Ordovician limestone drilling with the combination of logging technology based on seismic data.Through the method of mathematical geology,the occurrence of Ordovician limestone canbe predicted accurately based on 3 Dseismic exploration technology,then to get the geological results of Ordovician limestone,which can get a better method than that traditional prediction one.The method of predicting the occurrence state of top interface of Ordovician limestone based on 3 Dseismic exploration technique is realized,which gets better geological effects.
