油层产能的确定，目前主要依赖于试油、地层测试及试术等方法。随着录井技术从定性到定量的发展，地化录井产能预测方法解决了随钻预测产能的问题。文中介绍了地球化学录井技术原理，阐明了产能控制因素与地化录井多数的关系，建立了产能预测方程。地化产能预测是一种技术和经济可行的随钻实时求产方法，对获取单层、特别是薄层产能参数具有重要的意义。它是对目前求产方法的必要补充，在实际应用中见到了良好的地质效果。
The determination of reservoir productivity currently relies mainly on methods such as oil testing, formation testing and piloting. With the development of mud logging technology from qualitative to quantitative, geochemical logging productivity prediction method solves the problem of predicted drilling productivity while drilling. This paper introduces the principle of geochemical logging technology, clarifies the relationship between production control factors and geochemical logging majority, and establishes the productivity prediction equation. Geochemical capacity prediction is a technically and economically viable real-time production-while-drilling method, which is of great significance for obtaining single-layer, especially thin-layer capacity parameters. It is a necessary complement to the current method of production, in the practical application to see a good geological results.
