摘要
大牛地气田为低渗-致密气田,因存在启动压力梯度等因素,修正等时试井曲线按常规方法处理出现异常,无法准确获取气井的产能方程。采用LIT法和异常曲线校正法对气田异常试井资料进行了重新处理,最终获得气井产能方程,为同类气藏产能试井可能出现的异常资料处理解释探索了新的途径。
Da Niudi gas field is a low permeability and tight gas field. Due to starting pressure, correct productivity equation can't be obtained through modified isochronal data with conventional method. LIT method and informal curve corrected method are used to reprocess informal data and corrected productivity equation can be gotten. This method can be a guide for the informal data in this kind of gas reservoir.
