根据油气层热解、试油等资料，提出了３种预测油气层早期产能的方法：一种是地质类比法，它是根据预测层位与对比模型有相似的油气水界面和构造来实现的；另两种是统计分析法和产油指数法，它们是根据数理统计原理，从不同角度对已经试油的层位进行系统分析，建立产能与多种参数的关系方程进行预测的。 According to the pyrolysis data of oil and gas layers and oil samples, three methods for predicting the early productivity of oil and gas reservoirs are proposed. One is the geological analogy method, which is based on the similar hydrocarbon-water interface and structure between the prediction horizon and the comparative model ; The other two are statistical analysis and oil production index method, which are based on mathematical statistics theory, from different angles of the oil layer has been systematically analyzed, the establishment of capacity and a variety of parameters of the relationship equation to predict.
