摘要:
针对海上油井地理位置分散、单井测试成本高等问题,为了及时掌握油井产量变化趋势、提高海上油井生产管理水平、实现海上油田智能化生产管理,开展了海上油田毛细管测压电泵井产量在线计量方法研究。从井下电泵输入功率与井下电机输出功率相等这一能量守恒原理出发,同时考虑电机参数变化的影响,结合井筒多相流计算方法与实测流量校正方法,建立了毛细管测压电泵井产量在线计算数学模型,并研究了其求解方法。现场应用表明,结合定期的实测流量校正,本方法的计算结果与实测结果吻合较好,最大相对误差小于5%。本文所建立的方法能实现电泵井产量在线计量、实时反映油井生产趋势。采用该技术能显著降低海上油田生产成本,对于提高海上电泵井生产管理水平具有重要意义。
Abstract:
Offshore oil wells are geographically dispersed, and their single-well testing cost is high. In this paper, therefore, an on-line production metering method for offshore electric pump wells with capillary piezometry was studied in order to grasp the production change trend of oil wells in time, improve the production management level of offshore oil wells and realize the intelligent production management of offshore oilfields. According to the principle of conservation of energy that the input power of downhole electric pump is equal to the output power of downhole motor, the mathematical model for the on-line production calculation of electric pump wells with capillary piezometry was established in consideration of the influence of the change of motor parameters, combined with the borehole multiphase flow calculation method and the flow rate measurement correction method. In addition, its solution method was researched. Field application indicates that combined with the periodic correction on measured flow rate, the calculation result of this method is better coincident with the measured result with the maximum relative error less than 5%. By virtue of the method established in this paper, on-line production metering of electric pump wells can be realized, and their production trend can be reflected in time. In conclusion, this technology can reduce the operation cost of offshore oilfields significantly, and is of great significance to improve the production management level of offshore electric pump wells.
