摘要
胜利油区断块油藏主要分布于东辛和利津等44个油田,动用储量占油区储量的33.8%,年产油量占32.7%,在油区内占有重要的地位。由于油田开发难度越来越大,对低级序断层的识别和分析成为影响复杂断块油田开发的重要因素。随着开发地震技术的不断发展,对这类断层的研究成为可能,文中从多角度研究了几种开发地震技术在低级序断层识别和分析研究中的综合应用。通过综合应用地质、地震、测井、开发动态等资料,多方位地判识低序级断层的存在,进一步深化低级序断层对剩余油分布和油田开发影响的研究。
Fault-block reservoirs are distributed in 44 blocks in Shengli Oilfield.The producing reserves of 33.8 percent belongs to the fault-block reservoirs in Shengli.The oil production of these fault blocks is over 32.7 percent of the all production in Shengli Oilfield.So the fault-block reservoirs act an important role.Aimed at the difficulties of oil development,it is very important to identify and analyse the low-grade fault of oil-bearing blocks.Along with the progress of production seismic techniques,it becomes possible to analyse these kinds of faults.The integrated application of new seismic techniques are focused in this paper for identifying and studying the low-grade faults.According to the integrated applications of the data such as geology,geophysics,welll logging and production,more and more low-grade faults are proved in some faulted blocks.The influences of the low-grade faults on the distribution of remaining oil and the development of the blocks are studied deeply.
