摘要:

特低渗断块油藏由于储层物性较差、注水容易造成储层损害而不能进行有效开发。在此以花园断块油藏为例,通过对特低渗油藏的油藏特征分析和储层伤害分析,有针对性地进行注水配伍试验、储层结垢预测、注水药剂的筛选和酸化预处理工艺研究等注水实验评价,为特低渗油藏注水抑制储层损害、方案优化提供基础数据,在现场试验中取得明显效果。

Abstract:

The extra-low permeability block reservoirs can not be exploited efficiently because of its poor physical property and reservoir damage by water injection. The paper, taking Huayuan oilfield as the case, analyzes the reservoir characters and reservoir damages of extra-low permetyvoen ijection match experiment, scale formation prediction, the medicaments' choose and the acid pretreatment's study is made. These experimental evaluations provide the basic information to inhibit the reservoir damages and optimize the water injection. This study has been well applied in field test.

Key words: water injection production, extra-low permeability, water-injection match, reservoir damage
