Advices for Well Jiaoye XHF, Fuling Shale Gas Field by Analyzing Production Data
摘要
Abstract
Fuling shale gas field starts the first commercial production of shale gas in China.Hence, it is of great significance to analyse the production data from Well Jiaoye XHF, as the longest production period in this shale gas field.Pesently, this well has entered the intermittent stage of development, but there is no any experience that can be referenced.By analyzing the historical data and the comparison of the current production, this study figures out the evidence for intermittent production period.According to the analysis, the best way is to shut the well to recover energy and to use intermittent way to produce more gas when production pressure is the same as the output pressure.In view of the present output pressure, the system can effectively avoid the gas flooding and guarantee the normal well production based on the historical analysis of liquid gas wells and the summary of production time between wells.Meanwhile, flowing material balance method and output decline trend are used to estimate the recoverable reserves conservatively for the well and calculate the residual recoverable reserves.These estimates suggest that this well still has a significant mining potential and economic benefit.关键词
