摘要
提出了一种应用灰色理论和优化技术处理三相流产出剖面资料的方法。该方法以滑脱模型为基础 ,建立极小化目标函数及视流体速度 (流量 )、密度、持水率、温度和压力等测量参数的理论响应方程。在资料解释之前 ,首先根据井的近期动态监测资料运用灰色模型 GM(1 ,1 )进行参数预测。最后将预测结果作为初值代入优化模型中处理得到最优解。
If fluid flowing pressure is smaller than bubble point pressure, downhole fluids flow in a flowing regime of oil/gas/water phase In view of the problem of three phase flow interpretation, a method for applying grey theory and optimization technique to processing three phase producing profile is presented This method sets up the minimal target function and ideal response equations of apparent fluid velocity (flow rate), density, holdup, temperature and pressure on the basis of slip models It uses grey model GM(1,1) in predicting some parameters based on the recent dynamic data before interpreting data The predicted results are taked as primary values and used in optimization model to get the optimum results
