摘要(Abstract):

渤中凹陷西部斜坡带发育大量不同级别的断裂,为构造圈闭和油气成藏提供了良好条件,但同时也为构造解释带来较大挑战。以渤海海域B8油田为例,借助方差属性和边缘检测体属性在不同级别断裂识别中应用以及各种属性体剖面与平面的分析,大幅度提高了地震资料对断层的识别和解释精度,为复杂断块油田评价井部署提供了重要依据。
A great number of faults and fractures with various sizes develop in the western slope and belt of Bozhong Sag,which provide good conditions for the structural traps and hydrocarbon accumulation,but at the same time also result in much bigger difficulties for the tectonic interpretation.Taking Bohai Oilfield B8 as an example,by means of the application of the variance & edge detection attributes in different-level fracture recognitions,and the cross-section and planar analyses of various attributes,the recognitions and interpretations of the faults can be greatly improved by the seismic data,thus the important evidences for the appraisal well arrangement in complex fault-block oilfields have been provided.
