摘要
根据致密油井典型生产曲线公式,分析得到采用不同生产时间确定的递减率的关系,以及递减率与双曲公式中递减因子的关系,通过参数建立典型生产曲线。通过实例分析建立致密油典型生产曲线的3种数值拟合方法,并对3中方法建立的典型生产曲线进行分析。结果表明,在考虑关井时间情况下建立的典型生产曲线无需考虑生产时率的影响,并且方便对产量进行预测。该方法建立的典型生产曲线能更好的应用于致密油单井开发评价。
Get the relationship between initial decline and decline factor based on analysis of Typial Curve formula. This is one method to generate the Typical Curve. There are three projects to build Typical Curve form real production data. After analysis,another method to generate Typical Curve by numerical match without considering production hour ratio is recommended,because the Curve built by this method is easy to be used for forecasting production of well.
