【摘要】：连续混配压裂酸化工艺技术是将先配液、再施工的常规工艺改为“边配液边注入”的连续式施工工艺。配置液体时,所有的化学添加剂都在施工过程中加入,不但实现实时调整各种化工料和液体配比,还可根据实际施工情况配制不同液体,不存在液体浪费、液体短缺、限制施工等现象,并能有效提高压裂酸化施工效率。本文介绍了连续混配供送装置的国内外研究现状,综述了国内外连续混配供送装置的制造水平,详细分析了连续混配供送装置在油气田开发领域的应用前景。论文首先介绍了酸液连续混配供送装置的设计要求、设计方案与设计原理,对装置的重要组成部分混合罐结构、干粉添加装置、液体添加装置、膏状物添加装置、吸入和排出流量计、动力及控制系统等,进行了设计和优选。另外,通过实地考察,结合压裂酸化作业现场的施工工况和施工规模,对装置设计的初始方案进行了调整,将整体装置分解为两套小型装置:简易连续配酸装置和双联连续配酸装置。其中,单台装置最大排出排量可达到7m3/min,两套装置联合使用最大排出排量可达到10m3/min。混合装置能够实现水、酸液、干粉、膏体以及各种液体添加剂的连续混配和供送;集配酸、水粉混合、液体添加、整体混合及供液功能于一体;混配均匀,混合效果好,酸液质量高。装置为撬装结构,自带动力系统,体积小、重量轻,具有占地面积小、便于搬运等优点。通过在长庆苏里格气田酸化作业的现场试验,使用效果表明,装置能大幅提高配液质量和配液效率,减少人工成本,降低储酸罐数量,避免原液浪费,产生较大的经济价值。装置适用于站内及野外压裂酸化作业现场,能够满足各大油气田的作业需求。
[Abstract]:The continuous mixing fracturing and acidizing technology is a continuous operation technology, which changes the conventional technology of mixing fluid first and then to "injection while adding liquid". When configuring liquid, all the chemical additives are added in the construction process, which not only realize the realtime adjustment of chemical materials and liquid ratio, but also make different liquids according to the actual construction conditions. There is no liquid waste and liquid shortage. The effect of fracturing and acidizing can be improved effectively. This paper introduces the domestic and international research status of the continuous mixing and feeding device, summarizes the manufacturing level of the continuous mixing and feeding device at home and abroad, and analyzes in detail the application prospect of the continuous mixing and feeding device in the field of oil and gas field development. At first, the paper introduces the design requirements, design scheme and design principle of the acid continuous mixing and feeding device, the structure of the mixing tank, the dry powder adding device, the liquid adding device, the paste adding device, and the important components of the device, such as the mixing tank structure, the dry powder adding device, the liquid adding device and the paste adding device. Suction and discharge Flowmeter, power and control system, etc. were designed and optimized. In addition, through field investigation, combined with the operation condition and scale of fracturing and acidizing operation site, the initial scheme of the device design was adjusted. The whole unit is divided into two sets of small devices: simple continuous acid distribution device and double continuous acid distribution device. The maximum discharge capacity of a single unit can reach 7 m3 / min, and that of the combined use of the two devices can reach 10 m3 / min. The mixing device can realize the continuous mixing and feeding of water, acid, dry powder, paste and all kinds of liquid additives; Uniform mixing, good mixing effect and high acid quality. The device has the advantages of small size, light weight, small area and easy to carry. Through the field test of acidizing operation in Changqing Sulige gas field, the application results show that the device can greatly improve the quality and efficiency of distribution, reduce the cost of labor, reduce the quantity of acid storage tank, avoid waste of raw liquid, and produce greater economic value. The device is suitable for field and in-station fracturing and acidizing operations, and can meet the operational requirements of major oil and gas fields.
