摘要(Abstract):
针对杏树岗油田低渗透储层粘土矿物含量较高 ,储层伤害较严重及注水井存在着吸水能力差的问题 ,在杏树岗油田低渗透储层敏感性研究的基础上 ,研究了储层保护和酸化改造配套技术。室内实验和现场试验表明 ,该配套技术能有效提高注水井吸水厚度 ,增强油层吸水能力 ,并且现场施工成功率较高 ,有效期较长 ,可以满足杏树岗油田低渗透储层注水开发的要求
The low permeable reservoir in Xingshugang oilfield have some problems such as high clay mineral content,serious reservoir damage and poor water absorption capability of water injection wells. Based on the sensitivity study on the low permeable reservoirs in the oilfield, this paper studies the matching technique of reservoir protection and acidizing. Laboratory experiment and pilot test show that this technique can effectively increase the water absorption thickness of water injection wells and improve the water absorption capability of the reservoirs. It can be operated with a long effective term.
