Experimental study on reasonable production allocation of tight sandstone gas reservoir

Abstract

Due to the characteristics of poor physical property, low natural productivity, and rapid production decline of tight sandstone gas reservoir[1]. Therefore, it is usually necessary to optimize the working system of gas Wells after fracturing in tight gas reservoirs and determine the length of stable production period to ensure the large accumulated gas volume. In this paper, through the reasonable production allocation experiment on tight sandstone reservoir cores, the comparison diagram of instantaneous flow and cumulative gas volume at the end of stable production at different stable production rates is established, and the optimization experimental results of reasonable production allocation working system of gas Wells are obtained to determine the optimal stable production rate interval. Understanding and mastering the stable production capacity and reasonable production allocation of gas Wells in tight gas reservoirs provides the corresponding basis for formulating reasonable development measures of gas fields, and provides quantitative analysis means for optimizing the production allocation of gas Wells[2].
