【摘要】：随着科学的发展、技术的进步,油田开发中各种需求也在不断提高,功能强大的、自动化水平高的油井计量装置越来越被人重视。传统的稠油分离计量方法,是使得油、气、水分离后再分别进行计量,虽然计量精度较高、技术也比较成熟、,但是由于稠油自身的特性,难于进行准确计量,如果仍然采用传统的计量法,一是会造成比较高的投入、不经济实惠,二是低投入会造成计量精度低,因此寻找一种多井稠油在线实时计量装置就显得意义重大。论文通过全面的分析国内外油田常用稠油分离计量系统,结合我国稠油油田的实际情况,尤其是北方高含蜡稠油,提出了论文新型油井分离在线实时计量的构想。通过深入分析研究过后,设计出了一套比较切实可行、经济实惠的稠油油井计量系统。受到简易翻斗计量的启发,确定了以翻斗称重计量的设计方案,并设计了多油井分离在线实时计量的结构简图。通过对多油井在线实时计量系统进行全面的考察分析后,根据工作原理确定了各个部件选择类型,包括气体测量、温度测量、含水率测定、称重各个看似独立又紧密结合的部分。最后设计出最常见的西门子S7—300PLC控制系统对在线计量系统进行实时控制、数据收发、储存等。通过与传统的两相分离器、三相分离器进行深入的比对,对稠油直接进行称重的计量方式,计量环节更简单,一方面提高了稠油的计量准确度,而且结合PLC系统后,自动化程度更高,真正实现了远程监控、无人职守化的管理水平,是原油采油行业集输模式的一种突破,为提高劳动生产率、降低工人劳动强度,以及节省投资提供了有力的支持。通过本论文的研究,不仅能为稠油在线实时计量方式的后续研究提供理论依据,同时还能对一些其它类型的计量系统提供一定的参考。
[Abstract]:With the development of science and technology, a variety of requirements in oil field development are also increasing. The powerful and high level of automation oil well metering device has been paid more and more attention. Traditional heavy oil separation measurement method. Oil, gas and water are separated and then measured separately. Although the measurement accuracy is higher and the technology is more mature, it is difficult to measure accurately because of the characteristics of heavy oil itself. If the traditional metering method is still adopted, it will cause relatively high input, not economical, and low input will result in low measurement accuracy. Therefore, it is of great significance to find a real-time measuring device for multi-well heavy oil. Through the comprehensive analysis of the separation and measurement system of heavy oil at home and abroad, combined with the actual situation of heavy oil field in China. Especially for the heavy oil with high wax content in the north, the paper puts forward the conception of on-line real-time measurement of the new oil well separation, and after in-depth analysis and research, a set of practical and feasible is designed. The economical and economical heavy oil well metering system. Inspired by simple tipping bucket metering, the design scheme of weighing heavy oil well by tipping bucket is determined. The structure diagram of on-line real-time measurement of multi-well separation is designed. After a comprehensive investigation and analysis of the on-line real-time measurement system for multi-well separation, the selection types of each component are determined according to the working principle. Including gas measurement, temperature measurement, moisture content measurement. Weighing each seemingly independent and closely combined parts. Finally, the most common Siemens S7-300 PLC control system for on-line measurement system real-time control, data transceiver. Storage. Through the traditional two-phase separator, three-phase separator in-depth comparison, the heavy oil directly weighing measurement, measurement link is simpler, on the one hand, improve the measurement accuracy of heavy oil. Combined with the PLC system, the degree of automation is higher, and the management level of remote monitoring and unmanned management is truly realized. It is a breakthrough in the gathering and transportation mode of crude oil production industry, in order to improve labor productivity. Reducing the labor intensity of workers and saving investment provides a strong support. Through the research of this paper, it can not only provide the theoretical basis for the follow-up research of on-line real-time measurement of heavy oil. At the same time, it can also provide some reference for some other types of metering systems.
