摘　　要：以临兴气田为例,详细介绍了致密气上市储量评估流程与方法,初步建立了一套基于低渗致密气藏生产特征的上市储量评估体系,即:以单井为储量评估单元,采用井控法确定储量的级别与状态;采用动态法和概率法评估已开发和未开发储量;采用净现值法评估经济可采储量。这一评估体系解决了致密气藏井间地质差异大、生产特征复杂的问题,确保了评估结果的合理性。Taking Linxing gas field as an example,the evaluation process and method of listed reserves for tight gas were introduced in detail.Furthermore,based on production characteristic of low-permeability tight gas,an evaluation system of listed reserves was preliminarily established,that is,taking single well as reserve evaluation unit,use the well control methodto determine the level and status of reserves,adoptthe dynamic method and probability methodto evaluate the developed reserves and undeveloped reserves,and apply the net cash flow method to evaluate theeconomically recoverable reserves.The evaluation system addresses the problems of large geological differences and complex production characteristics between wells of tight gas,and is helpful to ensure the evaluation results are more reasonable.
