摘要
油气田在开发阶段最重要的一个环节就是储层产能的预测。而预测则主要基于储层的特征参数预算油气层在同一试采条件下的产出能力,主要包括孔隙度、渗透率和地层压力等,这些参数均来源于测井。测井资料在预测产能方面具有连续、准确、快速等优点,尤其在提供选层建议、快速求取产能方面起着关键性作用。通过对气层产能和测井参数之间的相关性研究,找到了产能的预测方法,即直接利用测井资料建立与产能间的关系,而不是利用解释的成果资料,这就避免了资料解释中带来的各种误差。最后,对实际井的资料进行分析评价,结果表明利用测井资料进行的产能预测效果良好。
The most important step for oil and gas field is to predict reservoir productivity, i.e. to predict the productivity of oil and gas reservoir under the same production test condition in accordance with data including porosity, permeability and formation pressure, etc. Logging data has advantages of continuity, accuracy and rapidity in reservoir prediction especially playing a key role in suggestion for layer selection and finding production rapidly, so the prediction method of productivity is described through research on the correlation between gas reservoir productivity and logging parameters. The method establishes a direct relationship with productivity by using logging data instead of achievement data of interpretation, which avoids various errors in data interpretation. It is shown that this method has good effect on productivity prediction by using logging material after evaluating and analyzing the actual well data.
