【摘要】：工厂化压裂是指像普通工厂一样,压裂设备基本上固定不动,对2口或2口以上的配对井进行同步压裂、顺序压裂或交叉压裂,连续不断的泵注压裂液和支撑剂的一种压裂作业模式。随着北美页岩气的成功开发,引起了全球非常规油气的勘探开采热,同时在北美最先应用的工厂化压裂模式也得到推广。国内引进后将应用领域进一步延伸,拓展到致密砂岩油气藏。本文从调研国内外工厂化压裂现状出发,从中获取一定经验,进而分析和研究了工厂化压裂配套技术,包括速溶胍胶压裂液体系、连续混配施工工艺研究、直井裂缝高度延伸规律、封隔器精细分层压裂技术、裸眼封隔器分段压裂技术、段内多裂缝压裂技术、同步压裂技术和裂缝监测技术等八项内容。开展了SX-18-20平台工厂化压裂先导试验,在做好该平台整体压裂设计和优化的基础上,提出了一套可行有效的工厂化压裂实施方案,通过现场实践,为后续开展的SY-82-17H大平台工厂化压裂提供了指导性研究。在SY大平台井实施工厂化压裂时,开展了选域布井、井身结构设计、平台井压裂设计优化等一体化研究,通过连续供液、连续供砂、连续泵注三大系统保障了流水线作业,应用了封隔器精细分层压裂、裸眼封隔器分段压裂、段内多裂缝压裂、同步压裂、裂缝监测等多项工艺技术。通过工厂化压裂的实施,在SX平台和SY平台均取得了良好的压裂改造效果,平均日产气量均明显高于区块原平均水平,同时也为气田开发节约了大量成本,提高了设备利用率,展现出了工厂化压裂的极大优势,为国内工厂化压裂的研究提供了宝贵经验。
[Abstract]:Industrial fracturing refers to the fact that, like ordinary factories, the fracturing equipment is basically immobile and simultaneously fracturing, sequential fracturing or cross-fracturing of two or more paired wells. Continuous pump injection of fracturing fluid and proppant a fracturing operation. With the successful development of shale gas in North America, the global unconventional oil and gas exploration and production heat has been caused, and the factory fracturing model, which was first used in North America, has also been popularized. The application field will be further extended to the tight sandstone reservoir after the introduction of domestic. Based on the investigation and investigation of the current situation of industrial fracturing at home and abroad, this paper obtains some experience, and then analyzes and studies the matching techniques of industrial fracturing, including the system of instant guanidine gel fracturing fluid and the continuous mixing operation technology. There are eight contents such as the rule of fracture height extension of straight well, Packer fine stratification fracturing technology, open-hole Packer fracturing technology, multi-fracture fracturing technology in section, synchronous fracturing technology and fracture monitoring technology. The pilot test of industrial fracturing on SX-18-20 platform is carried out. On the basis of the overall fracturing design and optimization of the platform, a set of feasible and effective industrial fracturing implementation scheme is put forward, and the field practice is carried out. It provides guidance research for industrial fracturing of SY-82-17H platform. In the process of industrial fracturing in SY large platform wells, the integrated research on well layout, wellbore structure design and fracturing design optimization of platform wells is carried out. Through continuous fluid supply, continuous sand supply and continuous pump injection, the assembly line operation is ensured. Packer fine layer fracturing, open hole Packer fracturing, multi-fracture fracturing in section, synchronous fracturing, fracture monitoring and so on are applied. Through the implementation of factory fracturing, good fracturing effect has been obtained on SX platform and SY platform. The average daily gas production is obviously higher than the original average level of the block. At the same time, it saves a lot of cost for the development of gas field and improves the utilization ratio of equipment. It shows the great advantage of factory fracturing and provides valuable experience for the research of factory fracturing in China.
