摘要

以典型碳酸盐岩裂缝型有水气藏为例，阐述了裂缝型气藏三维地质建模与数值模拟一体化气藏评价技术。首先应用三维地质建模技术，利用地质、测井等测试资料，进行地层格架、断层、裂缝及相模型的建立，为气藏数值模拟提供了初始静态地质模型；其次，通过数值模拟技术，利用生产动态测试资料，通过历史拟合调整完善数值模型；最后，对不同采气速度、增压开采工艺、排水采气工艺等开发措施进行指标预测评价，最终确定合理的开发调整方案。生产实践表明，应用气藏一体化评价技术能实现不同开发阶段的协同管理，为复杂气藏调整开发方案提供了依据。

Abstract

As an example of typical carbonate water gas reservoir, we discussed the integrated evaluation techniques for fractured-vuggy reservoir numerical simulation of 3D geological modeling.Firstly, based on geology and logging data, we used the application of 3-D geological modeling to set up the geological model of stratigraphic framework, fault and discrete fracture network, so that the initial static geological model can be built for gas reservoir numerical simulation.Secondly, based on the production performance data, we used the numerical simulation to get the reasonable gas reservoir mode by means of history matching and parameters adjustment.Finally, we got a reasonable development plan on predicting and valuating development indexes of different gas velocity, pressurization mining technique and gas drainage technology.The production practice showed that application of integration technology of gas reservoir evaluation in the fracture water-gas reservoir could realize the different development stages of cooperative management for the complex reservoir and provide reference for adjusting development scheme.

Key words： Fracture reservoir; Discrete fracture network model; Numerical simulation; Pressurization mining.
