摘要

随着油田开发的不断进行, 多数老油田进入开发后期, 增油潜力日渐降低。一些如低渗、潜山等难动用储量油藏的重要性逐渐凸显。河口地区碳酸盐岩裂缝性油藏储量丰富,更需对该类油藏的开发工艺进行研究与应用。在借鉴国内外同类型油藏开发的基础上, 与相关科研院所合作, 对富台油田、渤深6块等深层潜山油藏区块的储层发育特征、开采特征进行了研究, 着重对开发潜山油藏的主导工艺技术—— 酸压技术进行了探索, 初步形成了适用于河口地区碳酸盐岩裂缝性油藏的酸压工艺, 并进行了推广应用, 取得了良好效果。通过潜山油藏酸压技术的研究和应用, 现场的试验证明, 对该类油藏实施多级交替注入复合酸压工艺是成功的, 适合河口地区深层潜山油藏的地层特点, 该技术满足了高温、深层潜山油藏酸压的要求。

Abstract

W ith the developm ent o f the o ilfield, m ost o ilfie lds com e
to the phase o f production dec rease and are hard to increase
the production. The storab ility o f som e low perm eab ility and
buried h ill type reservo ir w ill become mo re important. The
effective exploita tion of these reservo irs is important fo r the
ad justm ent o f increasing production constitution and the
re tardation of decreasing. Large reserves ex ist in the c rev iced
ca rbonate form a tion in H ekou. It is necessary to study the
explo itation technique o f th is type o f reservo irs. Coopera ting
w ith o ther research institutes and investigating the technique
used in the sam e type of rese rvo irs, the ac id fractur ing
technique is studied in Futa i o ilfie ld and Boshen 6 area after
analyzing the character istics and deve lopm ent history. The
application results show that it is effective to the reservo ir by
alterna ted in jec tion. It cou ld be used at the tem perature
betw een 150􀀁 and 170􀀁 and the dep th be tw een 3 900 m
and 4 600 m, wh ich a re satisfied w ith the dem ands of the
buried hill type reservo ir.
