摘要
油气田的合理产能是油气田开发工作者最为关心的问题,是衡量开发方案执行情况以及制定开发调整方案的基本依据。合理产能的评价常用的方法主要有:采气指示曲线法、数值模拟法、产量不稳定分析法以及矿场生产统计法等方法,具体应该选用哪种方法需要根据油气田自身特点而定。针对苏里格气田西区的苏59区块投产时间较短,气水同产,难以进行产能评价及合理产量确定等问题,开展了对区块的产水特征研究。采用生产资料拟合建立气井模型和矿场生产统计两种方法对该区块进行合理产能评估,并用两种方法的配产结果进行综合分析,进而评价区块气井的合理配产情况,为苏里格气田西区含水气藏气井产能评价及合理产量的确定提供了依据。
The proper production capacity of an oil/gas field is a critical problem to which development operators attach great importance. It is the foundation for measuring and adjusting a development program. Commonly used production capacity evaluation methods include indicating curves of gas production method, numerical simulation, analysis of unstable yield and mineral production statistics etc. Water producing characteristics of Block Su-59 of Sulige Gas Field were explored. Applying RTA, we evaluated proper production capacity by creating gas well model and by using field production statistical method. Then we discussed the adaptability of the two evaluation methods and evaluated the proration production of Block Su-59. We believe that the research provides the reference for gas well productivity evaluation and the determination of reasonable production of the water-bearing gas reservoirs in the west of Sulige Gas Field.
