兴隆台采油厂欧利坨、荣兴屯、大洼等油田由于储层低渗、储层堵塞等原因,部分注水井存在注水压力高、欠注、注不进等问题,影响了油田注水开发效果,制约了油田采收率的提高。针对这一问题,近年来我们积极开展水井增注工作,探索适应我厂水井增注的新工艺新技术,对多氢酸解堵技术开展研究实验,拟解决我厂砂岩油藏水井堵塞的问题,该技术有望解决我厂水井注不进或欠注问题,为实现注上水、注够水、注好水的目标提供有力技术支持。
Due to such reasons as low permeability of reservoirs and blockage of reservoirs, some injection wells have problems of high water injection pressure, under-injection and injection failure, affecting the development of oilfield waterflooding Effect, restricted the improvement of oil recovery. In response to this problem, in recent years, we actively carry out well injection work to explore the new technology to adapt to the well injection wells new technology, research on hydrogen removal of plugging technology to solve the problem of clogging wells in our sandstone reservoir , The technology is expected to solve the problem of not filling or not filling well in our well and provide strong technical support for achieving the goal of injecting water, injecting enough water and injecting good water.
