【摘要】：由于油气水三相流流动的复杂性,目前还没有具有普通适用性的模拟计算公式来计算混输管道的工艺设计。PIPEPHASE软件在这一领域运用的比较广泛,自身具有计算模型简单化、缩短时间等特点,采用比较简单的经验计算公式组合。PIPEPHASE软件内有多种经验计算公式,由于每一种计算公式的适用范围不同,所以便会导致在相同条件下,通过各个公式计算出来的结果会不一样。所以在利用PIPEPHASE计算多相流混输管道压降时,所选用的经验计算公式会影响最终的结果。每种经验公式都有他相适应的油品物性,而PIPEPHASE软件无法根据现有的条件做出相适合的判断,并选取较为匹配的公式,所以在利用PIPEPHASE软件模拟计算时,人为选择会对结果造成比较大的影响,误差相对的也会增加,还需要利用实验和现场的实际数据进行核实,分析其影响因素。北三三转油脱水站是属于萨北油层的脱水站,该站管网复杂,且运行时间长,因其特殊情况的存在,导致管道腐蚀现象增多,为了保证该脱水站的正常生产运行,就需要对站内管线进行经常性的检查,并对腐蚀导致不能正常生产的管线进行更换,本文正是针对这种情况,通过PIPEPHASE软件,运用更准确、更直观的软件技术来分析北三三转油脱水站的管道运行基本情况,从而为此后选取合理的设计参数打下坚实的基础,并为提高管道安全生产系数提供重要的保障。本文利用PIPEPHASE软件,根据北三三转油脱水站所提供的生产数据,将模拟出的结果与实际数据进行误差对比,并对北三三转油脱水站的部分管网进行误差因素分析,分析出含水率、管路温度、产油量、产气量、管径大小等因素对计算误差有影响。其中DR的计算模型应用于北三三转油脱水站的误差最小,但当产油量大于140m3/d或含水率大于90%时,该方法的误差变高,因此对PIPEPHASE中的压降相关式DR模型进行修正,修正后,扩大了DR的适用范围和计算精度,更加适用于北三三转油脱水站的压降计算研究,为工程设计建设提供可靠的依据。最后,利用C++Builder6.0软件自主编制一套适用于北三三转油脱水站的程序,该程序可以自由录入管道的基本参数,流动参数,节点数据以及图象的显示。
[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.
