摘　　要：利用区块三维地震数据体,沿煤层提取了构造曲率属性,利用构造曲率法预测了区块裂缝发育特征,形成裂缝预测玫瑰图,对裂缝的密度与方位进行了预测。通过与单井压裂裂缝监测结果对比,预测结果与监测结果一致,证实了该方法的可靠性,可指导井位部署。在部署过程中,一是垂直于裂缝方向部署水平井,二是在裂缝较发育区,采用筛管完井,在裂缝不发育区,采用套管压裂水平井,均取得较好效果,提高了区块开发效果。Using the 3D seismic data volume of the Block,the structural curvature attributes are extracted along the coal seam,and the structural curvature method is used to predict the fracture development characteristics of the Block,generating a fracture prediction rose diagram and predicting the density and orientation of the fractures.By Comparing with the monitoring results of individual well fracturing fractures,the predicted results are consistent with the monitoring results,confirming the reliability of this method and its effectiveness in guiding the deployment of well locations.During the deployment process,there are two strategies to be employed,one is to deploy horizontal wells perpendicular to the direction of the fractures,and the other is to use screen tube completion in areas with more developed fractures,and in areas without developed fractures using casing fracturing for horizontal wells.Both strategies have achieved good results,leading to an improvement in the Block's development efficiency.
