Experimental study for pressure drop of variable mass flow in horizontal well
摘要
Abstract
The flow in the horizontal well is the variable mass flow due to the inflow through the perforated holes. Pressure drop due to inflow was measured in a horizontal perforated pipe loop by using water as working fluids. The experiment result shows that pressure drop grows as a result of increasing injection ratio. The mixture of inflow and main flow can cause the additional pressure drop. Moreover, the additional pressure drop has linear relationship with the ratio of acceleration pressure drop and injection ratio. A new model of pressure gradients for the vary mass flow in perforated pipes was developed. The total pressure drop consists of two parts including perforated pipe wall friction loss and additional loss. The predictive values by new model is in good agreement with true values, the average relative error is 7. 5%. The accuracy of the model proposed in this paper is better than other models. So the new model can be used in coupled well and reservoir simulation model.关键词
