摘要
中牟页岩气区块在目的层系储层中存在裂缝发育带,但由于对裂缝发育规模及分布范围认识不足,影响水平井的部署及页岩气的开发.本文介绍了利用三维地震数据检测裂缝的技术原理、计算方法及关键参数,通过RGB融合的裂缝检测技术,优选参数和属性数据计算,结合该地区的地质认识和地震响应特征,将最终优选的曲率和蚂蚁追踪属性结果进行属性融合.通过裂缝检测结果与测井资料对比,验证了裂缝预测的可靠性,可以将融合后的数据体预测中牟地区页岩气的裂缝发育情况,从而有效提高该区块水平井页岩气的钻探效果.
In the Zhongmou shale gas block,there are fracture development zones in the target strata reservoirs,but due to insufficient understanding of the fracture development scale and distribution range,the deployment of horizontal wells and the development of shale gas are affected.This article introduces the technical principles,calculation methods and key parameters of the use of 3 D seismic data to detect cracks.Through RGB fusion crack detection technology,optimal parameters and attribute data calculations,combined with the geological knowledge and seismic response characteristics of the area,will finally optimize the curvature Perform attribute fusion with the ant tracking attribute result.The fracture detection results are compared with logging data to verify the reliability of fracture prediction.The fused data volume can be used to predict the fracture development of shale gas in Zhongmou area,thereby effectively improving the drilling effect of shale gas in horizontal wells in this block.
