X油田M区精细地震构造解释技术探讨

Discussion on Fine Seismic Structure Interpretation Technology in M Area of X Oilfield

X油田M区断层广泛发育,构造复杂,是典型的复杂断块油藏。该区开发程度已经进入中后期,构造的刻画精度在一定程度上影响着该区的开发水平。为了提高该区的构造认识精度,通过研究总结出以断层解释技术和构造成图技术为核心的地震精细构造解释技术,其中包括层位精细标定技术、三维断层解释、沿层相干体切片、井控变速成图等。这些技术在该区广泛运用,并根据认识成果指导实际生产,取得了良好效果。

Faults are widely developed in M area of X oilfield and the structure is complex.It is a typical complex fault block reservoir.The development degree of the area has entered the middle and late stage,and the description accuracy of the structure affects the development level of the area to a certain extent.In order to improve the accuracy of structural understanding in this area,the seismic fine structural interpretation technology with fault interpretation technology and structural mapping technology as the core is summarized through research,including horizon fine calibration technology,three-dimensional fault interpretation,layer coherent volume slicing,well control variable speed mapping,etc.These technologies are widely used in this area,and guide the actual production according to the understanding results,and achieved good results.
