致密低渗透气田的试井特征分析--以新场气田为例

经对新场气田的试井资料处理,建立了不同类型储层典型井试井解释范例,得出低渗透试井判别式和判别图版,对该区具有低渗透特征的试井曲线进行了讨论。根据试井结果,可识别气藏(气层)储集类型,确定产层物性参数,为气藏动态分析提供基础资料。为开发致密低渗砂岩气藏、保持稳产高产奠定基础。

Well Testing Character Analysis for Tight and Low Permeability Gas Field- Taking Example of Xinchang Gas Field

By the process for well testing data of Xinchang gas field, the standard interpretative samples for different type of reservoir have been established and the discriminating formula and plate of well test in the low permeability reservoir are reduced and the character of testing curves in this district is preliminarily discussed. According to testing result, reservoir type is determined,physical parameters can be confirmed and that provides basis data for dynamic analysis of the gas reservoir and establishes a basement for efficiently developing dense and low percolation sand reservoir and keeping a high gas potential steadily.
