针对天然气的开发特点，优选出了方便实用的可采储量标定方法。以气田开发数据库为基础，采用面向对象的程序设计语言VC＋＋，编制了可采储量标定软件，该软件集数据处理、物性参数计算、可采储量标定、结果输出4个模块为一体，计算快捷、迅速、准确，运行稳定、安全、可靠，提高了天然气可采储量标定的精度和工作效率。

According to the character of natural gas, convenient and applied demarcating methods are chosen. Based on the development database of gas field, the demarcating software of recoverable reserves is developed by using the program of VC＋＋, which concludes four models： the pretreatment of database, calculating of parameters, demarcating of recoverable reserves and outputting of results. It has the advantages of being easy to learn and put into use, and friendly data interface. The software improved the demarcating precision and work efficiency greatly.
