摘要
鄯善油田属于低孔特低渗油田,注水井注水压力逐年上升,注水井欠注已成为突出矛盾,严重影响油田注水开发效果。室内试验和现场经验认为储层敏感性、注入水水质、地层结垢以及增注措施的影响是油田注水井伤害主要因素。通过开展岩心溶蚀试验,认为多氢酸体系在该地区具有良好的适应性,并以此确定出用酸强度等关键参数,绘制了相应的应用图版。
Shanshan oilfield belongs to low porosity injection pressure rises year by year in injection and low permeability oil fields.The water wells.Owe injection water has become a prominent contradiction,which seriously affects the development of oilfield water injection. Laboratory test and field experience think that reservoir sensitivity,injection water quality, the influence of formation scaling and the measures augmented injection are the major factors of well damage in the oil field.Through the development of core dissolution test,we believe that the more hydrogen acid system has the good adaptability in the region. Through these,this paper identifies with the acid strength of key parameters and draws the corresponding application chart.
