【摘要】：潜油电泵采油是目前国内外油田开采的一种主要方式。为了达到油井的最佳开采效果,需要随时了解油井的生产动态,及时掌握油井压力、温度等参数的变化情况,以便对油井采取合理的调整措施。当前相应的配套测试系统被国外少数公司垄断,开发一套潜油电泵机组温度、压力测试系统具有重要的现实意义。为了填补目前国内此类产品空白,解决从国外厂商订货困难、价格昂贵的问题,本文开发了自主知识产权的潜油电泵机组温度压力测试系统。完成了井下数据采集系统的硬件电路设计、传感器选型及信号调理电路的设计,电压电流转换电路的设计,双信号分时传输电路的设计;完成了井下滤波消压系统设计以及绝缘电路的设计;发明了井下用全密封抗渗体,完成了机械结构的设计;完成了井上系统的滤波电路设计、供电系统设计、井上数据采集系统设计、显示电路设计、电流环扩展接口设计以及系统软件的软件设计。从室内及现场试验情况来看,温度压力测试系统均能长期、可靠、精确地测量潜油电泵井下的温度和压力,测量精度分别压力在±0.5%以内,温度偏差小于±1.5℃;系统可在户内或户外长期使用,且运行较为稳定,使用寿命与国外公司产品基本相等,相对于从国外进口的装置,成本较低,且能及时提供所需配件及售后服务。
[Abstract]:Electric submersible pump production is a main way of oil production at home and abroad at present. In order to achieve the optimal recovery effect of oil wells, it is necessary to know the production performance of oil wells at any time and to grasp the oil well pressure in time. The change of temperature and other parameters in order to take reasonable adjustment measures for the oil well. At present the corresponding test system is monopolized by a few foreign companies to develop a set of submersible electric pump unit temperature. The stress test system is of great practical significance. In order to fill the gap of this kind of products in our country and solve the problem that it is difficult and expensive to place orders from foreign manufacturers. In this paper, the temperature and pressure test system of submersible pump unit with independent intellectual property rights is developed, and the hardware circuit design, sensor selection and signal conditioning circuit design of downhole data acquisition system are completed. The design of voltage and current conversion circuit and the design of dual signal time-sharing transmission circuit; The design of downhole filter and voltage suppression system and the design of insulation circuit are completed. The fully sealed impermeable body used in underground is invented and the mechanical structure is designed. The filter circuit design, power supply system design, data acquisition system design and display circuit design are completed. Current loop expansion interface design and system software design. From the indoor and field tests, the temperature and pressure testing system can be used to measure the temperature and pressure of submersible oil pump downhole for a long time, reliably and accurately. The measuring accuracy is less than 卤0.5% and the temperature deviation is less than 卤1.5 鈩，
