摘要:
低渗致密气藏水平井实际生产过程中,不同的气藏会有不同比例的水产出,但目前水平井气水两相非稳态变质量流及流体物性特征少有报道。针对此现状,利用复杂结构井多段井数值模拟技术,建立了低渗气藏压裂水平井变质量多相流数值模型,着重分析低渗气藏压裂水平井气水两相非稳态变质量流特征及水平井筒沿程水气比、持液率等两相流体参数变化特征。研究成果对低渗气藏压裂水平井设计及排水采气技术优选有一定指导作用。
Abstract:
In the actual production process of low-permeability tight gas reservoir, the ratio of water output is varied with various gas reservoirs. However, it was reported few studies related to the characteristics of unsteady gas-water two-phase variable mass flow and fluid physical property of horizontal wells. Aiming at this present condition, using the numerical simulation technology of multi-segment well with complex structure, a numerical model was established for variable mass multiphase flow of fractured horizontal wells in low-permeability tight gas reservoirs. The studies were emphasized on the characteristics of gas- water two-phase unsteady variable mass flow and the water-gas ratio and liquid holdup along the path of horizontal wellbore. The research results play an important role in the design of fractured horizontal wells and optimizing the drainage gas recovery technology for low-permeability gas reservoir.
