摘要

乐安油田草20块特稠油油藏馆一砂体自2001年起全面水淹。通过建立精确地

质模型, 进行开发历史拟合、蒸汽吞吐效果分析, 同时研究边水水侵规律, 研究边水对开发工作

制度的影响以及下一步控制边水可能的措施、方向和做法。结合建立的精细地质模型和模拟

结果, 对目前草20区块的剩余油分布规律进行分析, 得到有关定量的技术指标, 确定了后期改

善开发效果挖潜方向。

Abstract

The first sands o f the Ng Fo rm ation, an super􀀁heavy􀀁oil
reservo ir in Cao20 block in Lean o ilfie ld, have been
comp le tely flooded since 2001. In this paper, by bu ilding the
exact geo log ica l m ode ,l w e conduct the simu lation of the
developm ent h istory, analyze the e ffect o f the steam
stim ulation, then find ou t the ru les of the edge wa ter
invasion, investigate the e ffect of the edge w ater on the
developm ent pa rame ters, define the steps and the d irections
to contro l the edge w ater in future. Accord ing to the exact
geo log ical m odel that has been bu ilt and the simu la tion
resu lt, we can ana ly ze the ru les o f the rem a ind ing􀀁oil
d istr ibu tion in Cao20 block and get the quantitative technique
index w e want. A fte r tha t, w e find out a way to im prove the
production rate in the la te developm ent per iod.
