【摘要】：在油田平台井(也称丛式井)钻井施工中,由于受到传统的产量计量方式和原油输送方式的限制,需要等平台所有的井眼都完井后才能统一计量投产,浪费了大量的等待时间。本文针对油田平台井的计量投产问题,对平台井已完井的提前投产技术和装备进行了研究,进而研发出一套集原油产液量计量、含水率计量、多井切换计量、自动化远程控制等功能于一身的橇装式平台井计量投产装置。本文研究了目前国内外油井计量技术和装备现状,特别是对油井产液量计量及含水率计量技术和方法进行深入研究和探讨,对各种计量方法和仪器设备的优缺点进行分析对比,进而为后续的样机设计提供理论依据。在理论的指导下,本文结合油田实际情况,对平台井计量投产装置进行总体方案设计,形成一套科学、有效的计量工艺流程。以该流程为基本依据,进而对设备样机进行详细设计,包括样机总体结构设计,选井多通阀设计,热平衡含水仪设计,称重计量装置设计,橇体设计以及自动控制系统设计,最终形成一套完整的设备设计方案和施工图纸,并对样机的试验和使用方法提出了方向性的指导。根据设计方案,使用该设备后,平台井后续井眼钻井期间,前期完成的井眼可以提前计量原油产量并投产采油,大大提高了平台井的采油时效,提升了油田的投资效益。当一个平台的所有井完钻并决定以常规的流程投产时,该装置可整体搬迁至新的平台开始新的服务。
[Abstract]:In the drilling operation of platform wells (also known as cluster wells), due to the limitation of traditional production metering and crude oil transportation, it is necessary to wait until all well holes in the platform are completed before they can be measured and put into production uniformly. A lot of waiting time has been wasted. Aiming at the problem of measurement and production of platform well in oil field, this paper studies the technology and equipment of early production of platform well, and then develops a set of measurement of liquid production of crude oil. Water cut measurement, multi-well switching measurement, automatic remote control and other functions in one skid-mounted platform well measurement and production device. This paper studies the present situation of oil well measurement technology and equipment at home and abroad. In particular, the measurement technology and method of oil well liquid production and water cut are deeply studied and discussed, and the advantages and disadvantages of various metering methods and instruments are analyzed and compared. Then provides the theoretical basis for the follow-up prototype design. Under the guidance of the theory, this paper combined with the actual situation of the oil field, the overall design of the platform well metering and putting into production device, forming a set of science. Effective metering process flow. Based on this process, the prototype of the equipment is designed in detail, including the overall structure design of the prototype, the multi-way valve design of well selection, and the design of heat balance water cut meter. The design of weighing device, the design of skid body and the design of automatic control system finally form a complete set of equipment design scheme and construction drawings. According to the design scheme, after using the equipment, the platform well follow-up borehole drilling period. The well hole completed in the early stage can measure the crude oil production in advance and put into production, which greatly improves the oil recovery time of the platform well. When all the wells of a platform are drilled and decided to go into production in the normal process, the unit can be moved to the new platform to start the new service as a whole.
