河86地区生物灰岩油藏注水水源评价及储层伤害研究

注入水与地层水的配伍性和水质对地层的伤害是影响低渗透油藏开发的重要因素。在五敏实验研究的基础上，通过结垢趋势计算、室内流动实验对河86生物灰岩油藏注水水源进行了系统评价；通过膜滤实验、岩心堵塞实验、细菌堵塞实验等对注水水质控制指标进行了研究。研究结果表明，郝现联合站、史南联合站污水经处理后是理想的注水水源，并给出了主要水质控制指标。

Injected Water Source Assessment and Reservoir Damage Study on He 86 Biolithite Reservoir

Compatibility of injected water and formation water as well as the formation damage caused by water quality are the main factors to affect the development of low permeable reservoir. Based on the five sensitive experiment study, the injected water source of He 86 biolithite reservoir is assessed by means of scaling tendency calculation and lab flow test; injected water quality control index is studied by means of membrane filtration test, core jam test and bacterial plugging test. The study results indicate that the treated waste water from Haoxian gathering station and Shinan gathering station is the ideal injection water source, the main water quality control index is given in this paper.
