马岭油田北三区储层敏感性分析及氧化深穿透酸化解堵增注工艺研究

SENSITIVITY ANALYSIS OF RESERVOIR AT THE NORTH 3RD ZONE OF MALIN OILFIELD AND ITS ACIDIZING PLUG REMOVAL TECHNOLOGY

针对北三区注水压力高、水井注不进的现状 ,对其储层进行敏感性评价 ,研究了适应北三区储层的氧化深穿透酸化解堵增注工艺技术 ,有效地解决水井增注的难题。并在现场进行试验 ,取得了较好的效果。

For water injection pressure of water well is high at the north 3rd zone of Malin Oilfeld or can′t inject water,this paper evaluates the sensitivity of reservoir,and studies the deep penetrating acidizing plug removal augmented injection technology.Through field application,the technology solves effectively the knotty problem of water well augmented injection and obtains good effect.$$$$
