摘要
针对深层页岩气田开发中产量压力递减快、稳产难度大等问题,基于试采明确了深层页岩气"一高两快一长"的动态特征,开展了气井的全生命周期递减特征分析,明确了深层页岩气井产量、压力递减规律.应用单因素分析和灰色关联分析方法,开展了递减的影响因素分析,初步确定了影响递减的主控因素,为后续优选各阶段合理配产方法,形成了深层页岩气井全链条管控及合理配产.
Abstract
The dynamic characteristics of"one high,two fast and one long"of deep shale gas are defined based on trial production in view of the problems such as rapid decline of production pressure and difficulty in stable production in the development of deep shale gas fields.The life cycle decline characteristics of gas Wells are analyzed,and the production and pressure decline laws of deep shale gas Wells are defined.By using single factor analysis and grey correlation analysis method,the influencing factors of decline were analyzed,and the main controlling factors of decline were preliminarily determined,which formed the whole chain control and reasonable production allocation of deep shale gas Wells for the subsequent optimization of reasonable production allocation methods at each stage.
