摘要
在油藏工程研究中，计算油、气井的排驱半径与单井控制储量是一个常见而又难以确定的问题。特别在低渗储层中，往往不能得到一条合格的压力恢复曲线；有的异常高压油、气井由于受设备、技术条件限制而不能关井测压，无法获得不稳定测试资料。为此，采用产量不稳定测试的现代产量递减曲线分析方法，为计算早期试采的油、气并地层参数与单井储量提供了一个有效手段。
It is hard to calculate and determine the expulsion radius and single well control production of oilgas wells while studying oil reservoir engineering.Especially in low permeability reservoirs,a qualified pressure build-up curve can not be obtained frequently.Shut in pressures of some oil-gas wells with abnormal high pressure can not be tested as the limitation of equipment and technique conditions to fail in getting test data. So,the analysis method of present production decline curve of transient test provides an effective means for calculating stratigraphic parameters and single well reserves of oil-gas wells at early stage of producing.
