Abstract

Abstract:

According to the technical procedures and the characteristics of well -testing for a swabbing well and the formation pressure distribution of last swabbing, we developed a new mathematics model of well-testing analysis for the next step swabbing, and obtained the theoretical solution for this new model in Laplace space. Application results in Changqing oil field showed that this new model can describe the characteristics of transient drops of the well pressure in swabbing producer and the changes of the non- regularly characteristics of the well pressure during the swabbing procedures. The ratio of the well -testing data is used and the reliability of the analysis results can be also increased. The well pressure of a swabbing producing well can be calculated with this new model as well.

Key words: Swabbing well, well-testing, mathematical model, pressure
