不关井条件下求气井单井控制储量和泄流半径

Solving Controlled Reserve by a Single Well and Discharge Radial under the Condition of the Gas Well without Closing Well

气田生产管理中,气井单井控制储量和泄流半径是两个重要决策参数。对于这两个参数的求解,通常采用传统的物质平衡方法和试井方法,结果不易获得或存在误差。对于干气藏、少量产水或低凝油含量气藏,在不关井条件下,将井口压力换算成井底压力后,以Palacio-Blasingame方法为理论基础,以常用的EXCEL办公软件为计算工具,逐步计算得到气井单井井控储量和泄流半径。该计算方法实用、准确,具有较大的推广价值。

In the management of the gas field production,gas well,well controlled reserve by a single and discharge radial are two important decision-making parameters. For the solution of these two parameters,usually the traditional mass balance method and the well test method are used,whose results are not readily available or have errors.For the dry gas reservoir,a small amount of water production or low pour oil content gas reservoirs,under the condition of no closing well and after changing to the bottom hole pressure from the wellhead pressure,well controlled reserve by a single and discharge radial are calculated gradually based on the Palacio-Blasingame method theoretically and making the conventional Excel office software as calculating tools.The calculation method is practical,accurate and has a greater promotional value.
