Analysis of sand production law in sandstone underground gas storage development

By taking Shuang 6 gas storage as an example, the sand production law in sandstone underground gas storage development was analyzed. Based on the Shuang 6 gas storage reservoir geologic characteristics and production conditions, the reservoir of sand core physical simulation experiments was designed and the causes of store with sand and sand production mechanism were analyzed. The results indicate under the control of production pressure, the sand production in Shuang 6 gas storage reservoir is not serious, while the flow of water has a serious influence on production reservoir sand. Therefore, during the process of production management and sand control measures, the differential pressure should be controlled to reduce the gas seepage speed and control the water flow of reservoir, and then a good effect of active sand control was achieved.
