Problems solved by technology

The disadvantage of this method is that the production of oil and gas wells will inevitably be affected when the well is shut down for well testing.
The disadvantages of this method are: high data density, low precision, and generally wellhead data, and the interpretation results are more multi-solution
However, this method cannot perform simultaneous interpretation and mutual verification of t

Abstract

The invention discloses a well test interpretation method based on a pressure recovery well test and a production data well test.The method comprises the following steps that original pressure recovery data and original production data are processed to obtain a pressure recovery and production data body; the pressure recovery data in the pressure recovery and production data body is processed to obtain pressure recovery chart data; the production data in the pressure recovery and production data body is processed to obtain production dynamic chart data; the pressure recovery chart data and the production dynamic chart data are subjected to coupling processing in the same double logarithmic chart to obtain a pressure recovery and production coupling data curve; well test interpretation is conducted based on the pressure recovery and production coupling data curve.By means of the well test interpretation method based on the pressure recovery well test and the production data well test, the precision of well test interpretation is improved, and multiplicity of solutions of well test interpretation is reduced.

Description

technical field [0001] The invention relates to the technical field of gas reservoir well test analysis, in particular to a method for coupling and analyzing pressure recovery well test data and production test data to perform well test interpretation. Background technique [0002] Well testing is a special testing work for oil and gas wells, in order to determine the production capacity of the well and study the parameters and dynamic conditions of the reservoir. Well testing can provide reliable formation dynamic information, so well testing plays an extremely important role in the exploration and development of new oil and gas fields and the dynamic adjustment of old areas. Among them, pressure recovery well testing (pressure recovery well testing) and production data well testing are the two most commonly used well testing methods. [0003] Pressure recovery well testing is a traditional well testing method, which is to place a pressure gauge at the bottom or wellhead a...
