Powell optimization algorithm is the use of logging equipment to establish reasonable error function (non-correlation function), obtained with the Powell direction of the acceleration method to achieve the most hours of non-correlation function of the solution for gas, water two-phase flow, from the pre-gas, water flow the initial value, along the different wide to search, rectifiable outlet, water may be the biggest two-phase flow production. With the currently used production logging interpretation methods, this paper proposes the method has high accuracy, practical advantages, there are defects in the logs is still possible to get better results.
