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338%, 年产油量占327% , 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。
Abstract
Fault- b lock reservo irs are distributed in 44 blocks in
Sheng li O ilfield. The produc ing rese rves of 33. 8 percent
be longs to the fault - b lock reservo irs in Sheng l.i The oil
production o f these fault blocks is over 32. 7 percent of the all
production in Sheng li O ilfield. So the fault- b lock reservo irs
act an im portant ro le. A im ed a t the d ifficulties o f oil
developm ent, it is very important to identify and ana ly se the
low - g rade fault of o il - bear ing b lo cks. A long w ith the
prog ress o f production se ism ic techn iques, it becom es po ssib le
to ana ly se these k inds o f fau lts. The integrated app lica tion o f
new se ism ic techn iques are focused in th is paper fo r
identify ing and studying the low - grade fau lts. A ccording to
the integ ra ted applica tions of the da ta such as geo logy,
geophysics, w e lll logg ing and production, mo re and m ore low
- grade fau lts are proved in some faulted blocks. The
influences of the low - grade faults on the distr ibution o f
rem aining o il and the developm ent o f the blocks are stud ied
deeply.
