摘要
针对赵46井裂缝性砾岩储层的特点,采用了以单向压力封闭剂DCL-1和低荧光油溶性暂堵剂YD-1为主处理剂的钻开油层完井液体系。现场应用表明,该屏蔽暂堵完井液性能稳定、流变参数合理、携砂能力强、润滑性好,密度始终小于1.18g/cm^3,暂堵率为98.84％,反排解堵率达94.57％,满足了赵46井油层钻井和保护油层的需要。
To deal with the problem of reservoir damage during drilling operation, well completion fluid system containing sealing agent DCL-1 and plugging agent YD-1 was applied in Zhao-44 well. Applications indicate that this system possesses good property of lubrication and sand-carrying ability, completion fluid density was controlled below 1. 18 g/cmj, temporary plugging ratio and plug removal ratio are 98. 84% and 94. 57% respectively.
