摘　　要：断层及断层破碎带是影响渤海地区井漏的重要因素,针对该区多期次构造叠加、应力分布复杂等情况,结合行业技术发展现状,优选井-震相结合的方法精细刻画断层破碎带。首先,利用地震方差体进行断层破碎带的边界刻画;其次,在地震方差体的基础上,利用主动蚂蚁体和被动蚂蚁体相结合的方法精细识别断层面和充填带,实现对断裂破碎带宽度半定量的识别;最后,通过测井三孔隙度裂缝解释成果等对地震属性进行标定,并在井-震结合下实现对充填物的性质、破碎带物性、宽度进行精细定量刻画。实际应用表明,在井-震结合下可以有效预测和定量精细刻画断裂破碎带的规模,其成果在实际钻井过程中可提高对井漏预测的可靠性和准确性。Faults and fault-fractured zones are important factors affecting well loss in Bohai Sea area.In view of multi-stage structure superposition and complex stress distribution in this area,combined with the development of industry technology,the method of combining well and seismic is selected.Firstly,the boundary of fault fracture zone is characterized by variance cube.Secondly,based on the seismic variance cube,a combination of active and passive ant bodies is used to finely identify fault planes and filling zones,achieving semi quantitative identification of the width of fault-fractured zones.Finally,the seismic properties are calibrated by logging the results of three-porosity fracture interpretation,and the properties of the fill,the physical properties and the width of the fault-fractured zones are accurately and quantitatively described under the combination of well and seismic.The practical application shows that the scale of fault-fractured zone can be effectively predicted and quantitatively and accurately described under the combination.Therefore,the results can improve the reliability and accuracy of loss prediction in actual drilling process.
