摘要
目前作为油田开采的重要方式,注水工艺仍然为专业人员不断研究改进。尤其在低渗透油田的注水开发中,工艺技术要求更为严格,其中注水水质标准更是要求的关键。塔中16油田CⅢ油藏为深层中孔渗砂岩储层,根据其近年来的注水开发情况,结合相关的储层特征、储层敏感性、注入水腐蚀性及其与地层水的配伍性,对注入水悬浮颗粒含量及粒径、细菌含量和溶解氧等做出室内实验分析。在此研究基础上,提出了符合塔中16油田CⅢ油藏物性条件的水质推荐标准。
Currently, as an important way of oil exploration, professionals are still ongoing research to improve the injection process. Especially in the low pemleability oilfield water flooding development, the technology requirements more stringent, water injection water quality standard is the requirements of the key. Tazhong 16 CⅢ oil reservoir is deep in mudium porosity and permeability sandstone reservoirs. According to the waterflood development situation in recent years, article researches the content and size of suspended particles, bacteria and dissolved oxygen content, etc. through the laboratory experiment, and examines the sensitivity of reservoir damage, corrosion and injected water and formation water compatibility. Based on these studies, the paper puts forward recommendation quality conforming to well Tazhong 16 reservoir conditions.
