井-震结合下的断裂破碎带规模识别与应用
A Identification and application of the faulted-fractured zone scale under combination of well and seismic
摘要
Abstract
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 proper-ties 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 de-scribed 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 combina-tion.Therefore,the results can improve the reliability and accuracy of loss prediction in actual drilling process.关键词
