摘要

摘要: 储层丰度低、单井产量低是制约煤层气开发的瓶颈,因此如何提高钻井效率、控制成本是实现煤层气有效开发的关键。在总结延川南煤层气区块前期钻井经验的基础上,引入"井工厂"钻井模式,重点开展了井组及施工工序优化、预偏离防碰、导向钻具、个性化钻头和高效堵漏等降本增效技术的研究和实践,并利用学习曲线法对关键技术进行了持续优化,形成了煤层气低成本高效钻井技术。延川南煤层气区块808口井采用了煤层气低成本高效钻井技术,优质高效地完成了产能建设任务,其中平均单井钻井周期较产能建设前缩短30.3%以上,机械钻速提高了51.6%以上。研究与实践表明,煤层气开发时应用"井工厂"钻井模式能够显著控制钻井成本,提高开发效率,实现煤层气有效开发。

Abstract: Low reservoir volume and low single well production are bottlenecks that restrict coal bed methane(CBM) development, so how to improve the drilling efficiency and how to control the costs are the keys to the effective development of CBM. After summarizing the previous drilling experiences in South Yanchuan CBM block, the well factory drilling model was successfully applied and many technical research and field applications focused on reducing the cost and increasing benefits were carried out. Techniques included cluster well optimization, preventive deviation anticollision, navigational BHA, individualized bit design, efficient leak stoppage, etc. Then, the learning curve was used to optimize and improve key technologies and develop low cost and efficient drilling technology. Low cost and efficient drilling technology that was developed in the South Yanchuan CBM Block was applied to 808 wells and the operations were performed with good quality and high efficiency, in which the average single well drilling cycle was shortened by more than 30.3%, and productivity construction and penetration rate were improved by over 51.6%. The application showed that the well factory drilling mode could be employed in the field of CBM development to significantly control drilling costs, improve the efficiency to cost-effectively develop CBM.
