【摘要】：遼河油田稠油地面集輸技術(shù)發(fā)展相對(duì)成熟,但隨著油田開發(fā)進(jìn)入高含水階段,聯(lián)合站脫水困難導(dǎo)致的外輸原油含水率高、脫出水效果差的現(xiàn)象日趨嚴(yán)重。針對(duì)這一問題,本文選取錦州采油廠老三聯(lián)合站為研究對(duì)象,從提高原油脫水效率的角度出發(fā),以確保聯(lián)合站正常運(yùn)行為目的,對(duì)老三聯(lián)合站脫水效果影響因素進(jìn)行了較為全面的實(shí)驗(yàn)研究。實(shí)驗(yàn)部分基于遼河油田稠油現(xiàn)有兩段熱化學(xué)脫水工藝,由一段脫水室內(nèi)研究和二段脫水室內(nèi)研究組成,綜合考慮溫度、PH值、來液含水率以及破乳劑加藥量四種主要因素,采用單一變量法進(jìn)行了大量的室內(nèi)實(shí)驗(yàn),掌握各因素相互影響下稠油油水分離的規(guī)律,對(duì)實(shí)驗(yàn)現(xiàn)象及結(jié)果進(jìn)行機(jī)理研究。在軟件部分中,借助1st Opt將實(shí)驗(yàn)部分的數(shù)據(jù)進(jìn)行擬合,篩選出與之匹配的經(jīng)驗(yàn)公式;利用C#語言開發(fā)出一套界面良好、易于現(xiàn)場(chǎng)操作人員掌握的應(yīng)用程序,既能對(duì)現(xiàn)行脫水工藝下外輸原油含水率進(jìn)行預(yù)測(cè),也能優(yōu)選出合理工況下的脫水方案。此外,該應(yīng)用程序也在現(xiàn)場(chǎng)進(jìn)行了測(cè)試,以檢驗(yàn)其可行性,并將運(yùn)行中發(fā)生的問題加以修改。結(jié)論表明:針對(duì)不同來液含水率的原油,在合理的區(qū)間內(nèi)調(diào)節(jié)各項(xiàng)脫水工藝參數(shù),有利于站內(nèi)原油脫水并能改善稠油的脫水效果,也證明了該研究對(duì)錦采老三聯(lián)合站外輸原油含水率的達(dá)標(biāo)以及進(jìn)行下游生產(chǎn)有著重要的實(shí)際意義。
[Abstract]:The surface gathering and transportation technology of heavy oil in Liaohe Oilfield is relatively mature, but with the development of oil field entering into the stage of high water cut, the phenomenon of high water cut and poor effect of dewatering due to the difficulty of dehydration in the combined station is becoming more and more serious. In view of this problem, this paper selects the No. 3 United Station of Jinzhou Oil production Plant as the research object, from the point of view of improving the efficiency of crude oil dehydration, in order to ensure the normal operation of the joint station, The influencing factors of dehydration effect in LaoSan United Station were studied in detail. The experiment part is based on the existing two-stage thermochemical dehydration process of heavy oil in Liaohe Oilfield, which consists of the first stage dehydration laboratory study and the second stage dehydration laboratory study. Four main factors are considered synthetically: temperature and PH value, water cut and demulsifier dosage. A large number of laboratory experiments were carried out by using a single variable method to master the law of heavy oil-water separation under the mutual influence of various factors, and the experimental phenomena and results were studied. In the software part, the experimental data are fitted by 1st Opt, and the matching empirical formula is screened, and a set of application program with good interface and easy to be grasped by field operators is developed by using C # language. It can not only predict the water cut of crude oil under the current dehydration process, but also select the dehydration scheme under reasonable working conditions. In addition, the application was tested in the field to verify its feasibility and to correct any problems that occurred during the operation. The results show that adjusting the dehydration process parameters in a reasonable range for crude oil with different water cut is beneficial to dewatering crude oil and improving the dehydration effect of heavy oil. It is also proved that this study has important practical significance for the water cut of crude oil transported out of Jingai No. 3 Joint Station and the downstream production.
