摘要/Abstract

摘要： 为准确预测致密气藏多级压裂水平井在非线性渗流和复杂裂缝下的生产动态特征，通过双重连续介质-离散裂缝耦合模型对原始致密储层和水力压裂裂缝系统流动特征进行刻画并构建综合渗流数学模型，采用非结构三维四面体网格和控制体积-有限元方法建立全隐式数值模型，并通过修正Peaceman方法建立复杂压裂水平井数值井模型，从而获得准确的数值解。开展含水饱和度、应力敏感系数、压裂裂缝压开程度和空间非对称分布等关键参数对X致密气藏某区块压裂水平井生产动态的影响因素分析。研究表明，该模拟方法能准确预测致密气藏压裂水平井生产动态特征，为致密气藏的高效开发提供理论支撑和计算工具。

Abstract: In order to accurately predict the production performance of multi-stage fractured horizontal wells in tight gas reservoirs under the nonlinear flow mechanisms and complex fracture distribution characteristics, the dual continuum discrete fracture coupling model is used to describe the flow characteristics of original tight reservoirs and hydraulic fractures, and a comprehensive flow mathematical model is constructed. The unstructured 3D tetrahedron mesh and control volume finite element method are used to establish the fully implicit numerical model, and the modified Peaceman method is used to establish the numerical well model of complex fractured horizontal wells, so as to obtain accurate numerical solutions. The influences of some key parameters such as water saturation, stress sensitive coefficient, opening degree and spatial asymmetric distribution of hydraulic fractures on the production performance of fractured horizontal wells in one block of X tight gas reservoir are analyzed. The results show that the simulation method in this paper can accurately predict the production performance of multi-stage fractured horizontal wells in tight gas reservoir, and provide theoretical support and calculation tools for efficient development of tight gas reservoir.

Key words: tight gas, multi-stage fractured horizontal well, gas-water flow, control volume finite element method, numerical simulation
