给出了考虑注采比和启动压力梯度的平均地层压力和边界压力的确定方法。
The method is presented to determine formation average pressure and boundary pressure with threshold pressure gradient and injection-production ratio.
目前常采用关井的方法来确定气藏平均地层压力，但是应用该法通常将遇到一些困难。
Average gas pool pressure is currently determined by shutting up of Wells which is fraught with difficulties.
总的来说，关井会严重地影响气矿和用气单位的生产，如果专门为获得平均地层压力而关井，其代价太大。
At all events, shut-in of gas Wells would seriously affect the producer and the consumer, and it would mean too high a cost just for taking the average formation pressure.
