【摘要】：由于油氣水三相流流動(dòng)的復(fù)雜性,目前還沒有具有普通適用性的模擬計(jì)算公式來計(jì)算混輸管道的工藝設(shè)計(jì)。PIPEPHASE軟件在這一領(lǐng)域運(yùn)用的比較廣泛,自身具有計(jì)算模型簡單化、縮短時(shí)間等特點(diǎn),采用比較簡單的經(jīng)驗(yàn)計(jì)算公式組合。PIPEPHASE軟件內(nèi)有多種經(jīng)驗(yàn)計(jì)算公式,由于每一種計(jì)算公式的適用范圍不同,所以便會(huì)導(dǎo)致在相同條件下,通過各個(gè)公式計(jì)算出來的結(jié)果會(huì)不一樣。所以在利用PIPEPHASE計(jì)算多相流混輸管道壓降時(shí),所選用的經(jīng)驗(yàn)計(jì)算公式會(huì)影響最終的結(jié)果。每種經(jīng)驗(yàn)公式都有他相適應(yīng)的油品物性,而PIPEPHASE軟件無法根據(jù)現(xiàn)有的條件做出相適合的判斷,并選取較為匹配的公式,所以在利用PIPEPHASE軟件模擬計(jì)算時(shí),人為選擇會(huì)對(duì)結(jié)果造成比較大的影響,誤差相對(duì)的也會(huì)增加,還需要利用實(shí)驗(yàn)和現(xiàn)場的實(shí)際數(shù)據(jù)進(jìn)行核實(shí),分析其影響因素。北三三轉(zhuǎn)油脫水站是屬于薩北油層的脫水站,該站管網(wǎng)復(fù)雜,且運(yùn)行時(shí)間長,因其特殊情況的存在,導(dǎo)致管道腐蝕現(xiàn)象增多,為了保證該脫水站的正常生產(chǎn)運(yùn)行,就需要對(duì)站內(nèi)管線進(jìn)行經(jīng)常性的檢查,并對(duì)腐蝕導(dǎo)致不能正常生產(chǎn)的管線進(jìn)行更換,本文正是針對(duì)這種情況,通過PIPEPHASE軟件,運(yùn)用更準(zhǔn)確、更直觀的軟件技術(shù)來分析北三三轉(zhuǎn)油脫水站的管道運(yùn)行基本情況,從而為此后選取合理的設(shè)計(jì)參數(shù)打下堅(jiān)實(shí)的基礎(chǔ),并為提高管道安全生產(chǎn)系數(shù)提供重要的保障。本文利用PIPEPHASE軟件,根據(jù)北三三轉(zhuǎn)油脫水站所提供的生產(chǎn)數(shù)據(jù),將模擬出的結(jié)果與實(shí)際數(shù)據(jù)進(jìn)行誤差對(duì)比,并對(duì)北三三轉(zhuǎn)油脫水站的部分管網(wǎng)進(jìn)行誤差因素分析,分析出含水率、管路溫度、產(chǎn)油量、產(chǎn)氣量、管徑大小等因素對(duì)計(jì)算誤差有影響。其中DR的計(jì)算模型應(yīng)用于北三三轉(zhuǎn)油脫水站的誤差最小,但當(dāng)產(chǎn)油量大于140m3/d或含水率大于90%時(shí),該方法的誤差變高,因此對(duì)PIPEPHASE中的壓降相關(guān)式DR模型進(jìn)行修正,修正后,擴(kuò)大了DR的適用范圍和計(jì)算精度,更加適用于北三三轉(zhuǎn)油脫水站的壓降計(jì)算研究,為工程設(shè)計(jì)建設(shè)提供可靠的依據(jù)。最后,利用C++Builder6.0軟件自主編制一套適用于北三三轉(zhuǎn)油脫水站的程序,該程序可以自由錄入管道的基本參數(shù),流動(dòng)參數(shù),節(jié)點(diǎn)數(shù)據(jù)以及圖象的顯示。
[Abstract]:Because of the complexity of oil-gas-water three-phase flow, at present there is no general applicable simulation formula to calculate the process design of mixed pipeline. PIPEPHASE software is widely used in this field, and its own calculation model is simplified. In order to shorten the time and so on, there are many kinds of empirical formulas in the software of PIPEPHASE, because of the different scope of application of each formula, it will lead to the same conditions. The results calculated by each formula will be different. So the empirical formula will affect the final result when calculating the pressure drop of multiphase flow pipeline by using PIPEPHASE. Each empirical formula has its own physical properties of oil products, but the PIPEPHASE software can not make the appropriate judgment according to the existing conditions, and select the more matched formula. So, when using the PIPEPHASE software to simulate the calculation, The artificial selection will have a great influence on the result and the error will increase relatively. It is also necessary to use the actual data of the experiment and the field to verify and analyze the influencing factors. The Beisanshanzhuan oil dehydration station is a dehydration station in the Sabei oil reservoir. The pipe network of the station is complicated and the operation time is long. Due to the existence of its special circumstances, the corrosion phenomenon of the pipeline is increased. In order to ensure the normal operation of the dehydration station, It is necessary to carry out regular inspection of the pipeline in the station, and to replace the pipeline which is not normally produced due to corrosion. This paper aims at this situation, using the PIPEPHASE software to use more accurately. More intuitionistic software technology is used to analyze the basic conditions of pipeline operation in the North Sanshanzhuan Oil Dewatering Station, thus laying a solid foundation for selecting reasonable design parameters and providing an important guarantee for improving the safety production coefficient of the pipeline. In this paper, according to the production data provided by the North Sanshanzhuan Oil Dewatering Station, the simulated results are compared with the actual data by using PIPEPHASE software, and the error factors of some pipe networks of the Beisanshanzhuan Oil Dewatering Station are analyzed, and the water cut is analyzed. Pipeline temperature, oil production, gas production, pipe diameter and other factors affect the calculation error. The calculation model of Dr is applied to the North Sanshanzhuan oil dehydration station with the smallest error, but when the oil production is greater than 140m3/d or the water cut is greater than 90, the error of this method becomes higher. Therefore, the pressure drop correlation Dr model in PIPEPHASE is modified, and the correction is made. The application range and accuracy of Dr are expanded, and it is more suitable for the calculation of pressure drop in the North Sanzhuan Oil Dewatering Station, which provides a reliable basis for the engineering design and construction. Finally, a set of program is programmed by C Builder 6.0, which can input the basic parameters, flow parameters, node data and image of the pipeline freely.
