【摘要】：在油氣井開(kāi)采石油或天然氣的過(guò)程中,幾乎不可避免地要涉及到多相混合流體在垂直管道或水平管道中的流動(dòng)。油氣水混輸管道的壓降計(jì)算是油氣集輸管道設(shè)計(jì)及運(yùn)行管理過(guò)程中水力計(jì)算的主要內(nèi)容之一。由于垂直管道或水平管道中多相流的復(fù)雜性,在實(shí)際壓降的計(jì)算中多采用經(jīng)驗(yàn)計(jì)算方法進(jìn)行壓降的計(jì)算,以保證計(jì)算的準(zhǔn)確度。PIPEPHASE軟件主要用于油田集油系統(tǒng)油氣水三相流混輸計(jì)算,包括了油氣水多相混輸管道的穩(wěn)態(tài)計(jì)算模塊,其中提供了許多計(jì)算公式和方法。本文根據(jù)公開(kāi)發(fā)表的實(shí)驗(yàn)數(shù)據(jù),利用PIPEPHASE軟件中的多種方法對(duì)垂直管或水平管中多相流動(dòng)壓降進(jìn)行各種壓降計(jì)算方法的模擬,將模擬結(jié)果與試驗(yàn)結(jié)果進(jìn)行對(duì)比分析,確定出各種計(jì)算方法的實(shí)驗(yàn)誤差和計(jì)算誤差。同時(shí)也討論了原油含水率、油品溫度、油井產(chǎn)氣量等參數(shù)對(duì)計(jì)算結(jié)果和誤差的影響。本課題的研究,可以為油田實(shí)際應(yīng)用PipePhase軟件中計(jì)算方法的選擇提供了依據(jù),提高了計(jì)算準(zhǔn)確性,有助于油田生產(chǎn)管理。
[Abstract]:Oil?In the process of producing oil or gas in gas wells, it is almost inevitable to involve the flow of multiphase mixed fluids in vertical or horizontal pipelines.The calculation of pressure drop of oil-gas-water mixed pipeline is one of the main contents of hydraulic calculation in the design and operation management of oil-gas gathering pipeline.Because of the complexity of multiphase flow in vertical or horizontal pipeline, the empirical method is often used to calculate the pressure drop in the calculation of actual pressure drop.The PIPEPHASE software is mainly used in the calculation of oil-gas-water three-phase mixed flow in oil gathering system, including the steady state calculation module of oil-gas-water multiphase mixing pipeline, in which many calculation formulas and methods are provided.Based on the published experimental data, various pressure drop calculation methods for multiphase flow in vertical or horizontal tubes are simulated by using various methods in PIPEPHASE software. The simulation results are compared with the experimental results.The experimental error and calculation error of various calculation methods are determined.At the same time, the influence of the parameters such as crude oil water cut, oil product temperature and well gas production on the calculation results and error are also discussed.The research of this subject can provide the basis for the selection of calculation methods in the application of PipePhase software in oil field, improve the accuracy of calculation, and be helpful to oilfield production management.
