本文以罗228区高压欠注问题严重开篇,对采取的增注、日常洗井效果进行综合分析对比,从实践中总结出对高压欠注井治理措施几点认识以及问题管网优化改造方案;针对高压欠注井所处油藏地理方位不同,地层物性、注水条件、客观因素影响差异大,具体分析出高压欠注井欠注原因;及对引进的微弱酸新技术的效果分析,以及小排量压裂增注工艺的提出,总结出对罗228区高压欠注井的治理对策的几点建议。
In this paper, Luo 228 area under high pressure owe a serious issue of the beginning of the injection, take note of the daily washout effect comprehensive analysis and comparison, from practice, summed up the high pressure under-well governance measures and problems of pipe network optimization and transformation programs; In view of the difference of reservoir geography in high pressure under-injection well, the differences of formation physical property, water injection conditions and objective factors are large, and the causes of under-injection in high-pressure underfilled well are analyzed in detail; and the effect analysis of new weak acid introduction technology and small Displacement fracturing and replenishment technology proposed, summed up a number of recommendations 228 Luo high-pressure under-hole injection well governance measures.
