A NEW METHOD FOR ANALYSIS PRESSURE DECLINE OF POST-FRACTURING

With the development of whole fracturing technology for gas reservoir, more and more importance is attached to the post-fracturing evaluating technology. This paper introduces a new mathematical fitting method and develops a set of computer software for Windows, by which we can obtain the relevant parameters for post-fracturing evaluation.Some field examples show that the new method is simpler and more reliable compared with the conventional curve fitting method.
