摘　　要：针对研究区断层解释误差大、断层组合难等问题,利用井震结合断层解释、垂直断层走向剖面断层解释、二三维联动断层直接解释相结合的多技术联动方法,完成了研究区断层高精度精细解释,提高了断层解释精度和工作效率。结果表明,通过利用以上4项技术,断层走向、延伸长度有9处发生变化,断距小于等于5m的断点组合率由过去的88.3%提高到95.16%,大于5m断点组合率由过去的91.3%提高到100%。该方法的应用对油田开发具有较好的指导意义。Aiming at the problems of the large error of the fault interpretation and difficult combination among the faults in the study area, the high-precision fault interpretation in the study area was completed by means of the following multi-technique linkage: well-seismic combination, vertical fault strike profile fault interpretation and direct interpretation of two and three dimensional linkage faults, thus the interpretation precision and work efficiency were improved. The results show that with the help of the above four techniques, there are nine changes in the fault strike and extension length, the breakpoint combination rates of the fault throw less than or equal to 5 m have been increased from the past 88.3% to the present 95.16%, and moreover for those greater than 5 m, the values have been increased from 91.3% to100%. The application of this method has much better guiding significance for the oilfield development.
