| Well testing is the very important part in the reservoir exploration and exploitation. The data from the well testing is different from those from core analysis and logging. And the data can be obtained from the whole process of the exploitation of reservoir, so the more useful information can be obtained.The method and interpretation software of the single well testing has been perfectly developed. The analysis method and the software that the most popular in the world is based on the theory of single well, and they only can be used in the condition when there is no interfere or interfere is small.So, the study of the interference testing and the interpreting has become more and more important. And the study will be very helpful to exploit the reservoir.The experts of the world have studied the interference testing for many years, and the overseas study is relatively success, while the study gets behind in our country. Numbers of articles show that the interference testing has not meet the need of the oil field with the geological situation became complex during the course of exploitation. So the interference testing of complex medium has been given more attention.The paper study the interference testing of complex medium according to general process of well testing: physical model?Hnathematical model?dimensionless model?Laplace transform ? solve the model in Laplace space ?numerical reverse? solution of real space.The key of the paper is to establish the interference testing model of complex medium and seek the solution of them in Laplace space, then gain the solution of model using numerical reverse, and write the software by VB. Using the software, the type curve can be plotted expediently and the formation parameter can be obtained by matching the corresponding type curve.The models established in the paper are homogeneous reservoir, double porosity reservoir, dual-penetrate reservoir, composite reservoir and dual-porosity reservoir with gas-cap. |
