应用小井眼开窗侧钻技术是降低钻井综合成本,提高原油产量的重要途径之一。针对在小井眼开窗侧钻井固井过程中存在的主要技术难题进行了研究,并在胜利、中原、辽河等油田的现场应用中取得了成功。应用效果证明,该技术所制定的固井工艺方案合理,适用性强,设计开发的101.6mm及88.9mm系列尾管固井工具可靠性好,适用范围广,解决了小井眼开窗侧钻技术发展面临的主要技术难题,提高了固井质量,降低了钻井成本,具有较好的应用推广价值。
Application of Slim Hole Side Window Side Drilling Technology is one of the important ways to reduce the comprehensive cost of drilling and increase the production of crude oil. Aiming at the main technical problems in the process of well cementing in the open side of the slim hole, the successful application in the fields of Shengli, Central Plains and Liaohe Oilfields has been carried out. The application results show that the cementing technology scheme formulated by this technology is reasonable and adaptable. The 101.6mm and 88.9mm series of tail pipe cementing tools designed and developed have good reliability and wide application range, and solved the problem of side hole drilling technology Development of the main technical problems facing, improve the cementing quality, reduce drilling costs, with good value for the promotion of the application.
