摘要： 致密气是非常规天然气的一种，是国内天然气产量的重要组成部分，与页岩气和煤层气相比其开发技术更为成熟和现实。经过多年勘探开发，从鄂尔多斯盆地和四川盆地的多个致密气田中，获得了大量比较精确的储量数据，但在渤海湾盆地、松辽盆地等，致密气勘探调查处于起步阶段，勘探开发数据不充足,这些区块和地区的资源量数据也不完善。为了预测和评价国内致密气资源量，评价模型中选用VSD（variable shape distribution）模型，该模型与常规分形分布模型相比，比如对数正态分布和帕累托分布，具有精度高，拟合灵活准确的特点。在成熟度高的气田储量基础上，拟合出VSD模型所需的参数，然后利用这套参数预测评价出国内31个致密气田的资源量，为致密气的勘探部署和经济分析提供参考数据。

Abstract： Tight gas makes up big proportion of unconventional natural gas and it accounts for a huge proportion in domestic natural gas production. Comparing with shale gas and natural gas, the development technology of tight gas is much more mature. After years of exploration and development, relatively precise reserve number of Ordos basin andSichuanbasin has been acquired. However, the exploration survey of tight gas in Bohai bay basin and Songliao basin is just beginning, thus the exploration and development information is far less sufficient. In order to forecast and evaluate domestic tight gas reserve number, the variable shape distribution (VSD) model, characterized by high accuracy and flexible fitting, is applied in this paper. Based on highly mature gas field reserve, the reserve of 31 tight gas fields has been forecasted with VSD model. This can provide reference data for exploration and development and economic analysis of oil and gas.
Key words: tight gas; reserve evaluation; proved reserve; evaluation model; VSD
