【摘要】：隨著科學(xué)的發(fā)展、技術(shù)的進(jìn)步,油田開發(fā)中各種需求也在不斷提高,功能強(qiáng)大的、自動化水平高的油井計(jì)量裝置越來越被人重視。傳統(tǒng)的稠油分離計(jì)量方法,是使得油、氣、水分離后再分別進(jìn)行計(jì)量,雖然計(jì)量精度較高、技術(shù)也比較成熟、,但是由于稠油自身的特性,難于進(jìn)行準(zhǔn)確計(jì)量,如果仍然采用傳統(tǒng)的計(jì)量法,一是會造成比較高的投入、不經(jīng)濟(jì)實(shí)惠,二是低投入會造成計(jì)量精度低,因此尋找一種多井稠油在線實(shí)時計(jì)量裝置就顯得意義重大。論文通過全面的分析國內(nèi)外油田常用稠油分離計(jì)量系統(tǒng),結(jié)合我國稠油油田的實(shí)際情況,尤其是北方高含蠟稠油,提出了論文新型油井分離在線實(shí)時計(jì)量的構(gòu)想。通過深入分析研究過后,設(shè)計(jì)出了一套比較切實(shí)可行、經(jīng)濟(jì)實(shí)惠的稠油油井計(jì)量系統(tǒng)。受到簡易翻斗計(jì)量的啟發(fā),確定了以翻斗稱重計(jì)量的設(shè)計(jì)方案,并設(shè)計(jì)了多油井分離在線實(shí)時計(jì)量的結(jié)構(gòu)簡圖。通過對多油井在線實(shí)時計(jì)量系統(tǒng)進(jìn)行全面的考察分析后,根據(jù)工作原理確定了各個部件選擇類型,包括氣體測量、溫度測量、含水率測定、稱重各個看似獨(dú)立又緊密結(jié)合的部分。最后設(shè)計(jì)出最常見的西門子S7—300PLC控制系統(tǒng)對在線計(jì)量系統(tǒng)進(jìn)行實(shí)時控制、數(shù)據(jù)收發(fā)、儲存等。通過與傳統(tǒng)的兩相分離器、三相分離器進(jìn)行深入的比對,對稠油直接進(jìn)行稱重的計(jì)量方式,計(jì)量環(huán)節(jié)更簡單,一方面提高了稠油的計(jì)量準(zhǔn)確度,而且結(jié)合PLC系統(tǒng)后,自動化程度更高,真正實(shí)現(xiàn)了遠(yuǎn)程監(jiān)控、無人職守化的管理水平,是原油采油行業(yè)集輸模式的一種突破,為提高勞動生產(chǎn)率、降低工人勞動強(qiáng)度,以及節(jié)省投資提供了有力的支持。通過本論文的研究,不僅能為稠油在線實(shí)時計(jì)量方式的后續(xù)研究提供理論依據(jù),同時還能對一些其它類型的計(jì)量系統(tǒng)提供一定的參考。
[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.
