通过对涠洲油田群黏土矿物、敏感性、注入水质以及注入水自身结垢、注入水与地层水混合结垢等伤害因素的系统分析、评价,查找出注入水悬浮物含量及其粒径是目前涠洲油田注入水伤害的主要因素,其次为注入水自身结垢和注入水与地层水混合结垢伤害。提出了控制水质和改善防垢效果的建议,对更好地解决涠洲油田注水伤害问题具有一定的指导意义。
Through the systematic analysis and evaluation of the clay mineral, sensitivity, influent water quality, fouling of injected water and mixed scaling of injection water and formation water in Weizhou Oilfield, the content and particle size of suspended solids in injected water were found to be At present, the main factors of water damage in Weizhou oilfield are injected, followed by scaling of injected water and mixed scaling damage of injected water and formation water. Put forward the suggestion of controlling the water quality and improving the anti-scaling effect, which is of guiding significance for solving the water injection injury problem in Weizhou Oilfield better.
