Productivity Analysis Of Single Well In Shale Condensate Gas Reservoir

With the growing demand of society for green energy and the continuously rising of natural gas price, and the huge success of exploration and development of shale gas in America and Canada, shale gas has becoming a hot point in petroleum industry all over the world. The exploration and development of shale gas as well as condensate oil&gas in China is very late, therefore, a series of measurements and theory methods of exploration, development and evaluation criterion need to be established, especially the deliverability analysis method, this method has a great significance for guiding gas well production determine and related to ground facilities.This paper is based on extensively correlated literature of productivity evaluation in shale gas, and the migration mechanism of shale gas reservoir, combined with gas reservoir characteristics and production situation, production testing data, productivity test simulation calibration, test mining method and numerical simulation method were employed to evaluate the capacity of production of the three wells, the "Kcom-Pvt-K multicomponent" numerical simulation software was used to analysis affecting factors of the production capacity in gas reservoir.Results shows that if the test time is too short, the evaluated well capacity by the tested data would be higher than it actually is, while the gas well production capacity can be predicted well by the test simulation method, the test method and the numerical simulation method also which has a high consistency with gas well test in the late; Adsorption phenomenon, fracture permeability, the main fracture number and horizontal section length have great influence on gas well production capacity—adsorption, gas well production was stable in the late phase, parameters of the fracture permeability, the main fracture number and the horizontal section length,the better, the greater the output and the higher reservoir recovery.
