榆林南区动态跟踪模拟及稳产潜力评价

综合应用压降法、流动物质平衡法、产量不稳定分析法等落实了榆林气田南区动储量．并在动储量评价过程中，对新引进方法进行了改进，形成了适合榆林气田实际情况的低渗气藏动储量评价方法：以一点法产能试井为基础，对低渗气藏产能变化规律、气藏合理生产规模进行了论证；在三维精细地质建模的基础之上．结合气井生产动态特征，对全气藏生产井进行精细的历史拟合，建立了气藏动态模型，并以此模型为基础评价气藏稳产潜力。通过研究，在动储量评价、产能论证、稳产潜力方面取得了相应的成果，为榆林气田南区高效合理开发奠定了基础。

Dynamic Tracking Simulation and Evaluation of Stable Production Potentiality of Southern Yulin Gasfield

Application of pressure drop, flow of material halance method, yield analysis, and other unstable implementation of the Southern District of Yulin gas reserves moving, and moving reserves evaluation process, the introduction of new methods to improve, and formed a gas suitable for the actual situation of the Yulin low permeability gas reservoirs dynamic reserves evaluation method; To point Testing method based on the production capacity of low permeability gas reservoirs productivity changes and gas reservoir was reasonable scale of production verification; Fine in 3D geological modeling based on dynamic characteristics with gas well production, the entire production wells gas reservoir history matching the fine established gas reservoir dynamic model, and this model based on the evaluation of potential gas reservoirs stable. Through research in the evaluation of dynamic reserves, production feasibility studies, stable yield potential has made the corresponding results for the Southern District of Yulin efficient gas field laid the foundation for rational development.
