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 aspect of oil and gas fields in the development stage is the prediction of reservoir productivity. Prediction, on the other hand, is mainly based on the reservoir’s characteristic parameters to estimate the productivity of oil and gas reservoirs under the same test production conditions, mainly including porosity, permeability and formation pressure. All these parameters are derived from well logging. Logging data has the advantages of continuous, accurate and rapid prediction of production capacity. It plays a key role in providing layer selection and quick calculation of production capacity. By studying the correlation between gas production capacity and logging parameters, we have found a way to predict production capacity by directly using logging data to establish the relationship with production capacity, rather than using the results of interpretation, which avoids data interpretation In a variety of errors. Finally, the actual well data analysis and evaluation, the results show that the use of well logging data to predict the production capacity is good.
