Abstract: The modern well test interpretation technique is an automatic fitting and solution method by computer operating system integrated with exclusive software, by which the velocity and quality of well test interpretation can be greatly increased and improved. However, it is also closely related with the work ability of interpretation engineer. At present, many interpretation engineers can only finish the interpretation task by means of computer, they just know a little or basic theory and methods referred to the technique. This may not only directly influence the quality of well test interpretation made by them, but also influence their skill development. This paper elaborates the basic knowledge and methods of the modern well test interpretation technique, including dimensionless processing and unit conversion, definition and variation of differential of pressure, deduction of differential of pressure calculation method, dimensionless rate and typical curve, etc. Finally, two examples are cited to explain how to use modern well test interpretation technique for solution of various parameters required for homogeneous and dual porosity reservoir.
