Analysis of Dynamic Characteristics and Main Control Factors of Deep Shale Gas
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.
