Abstract

Abstract: It is precondition of preparing reasonable production testing scheme to precisely predict the natural productivity in production testing interval. This method for the natural productivity prediction is proposed based on analysis of plenty of logging and production testing data, by which several solutions to gain permeability could be provided; using logging data to predict both stock tank oil viscosity and in-situ crude viscosity is presented, and a regression equation for fluid productivity index vs. flow coefficient is established by Darcy equation. This method is characterized by fewer and easily acquired parameters, precisely predicted results and better practicability and feasibility. It is used to provide direct and reliable bases for the interval preference and the scheme optimization of production test.

Key words: production test, productivity prediction, viscosity, permeability, mobility, flow coefficient
