Crude oil property prediction method and system based on precutting test

The invention relates to a pre-cutting test-based crude oil property prediction method and system, and the method comprises the steps: obtaining second target data through judging whether a reference property curve meets a preset curve rule or not on the basis of obtaining first target data through employing known basic data and a preset database to execute physical property similarity matching operation; the second target data is pre-cut to obtain prediction data close to a use scene, the crude oil basic data and the crude oil evaluation experiment data are subjected to specific processing to form basic data for cutting calculation of a cutting tool, and the basic data are stored as a data source; and testing and verifying by using a result obtained by pre-cutting to obtain a predicted value of the target property data. 本发明涉及一种基于预切割测试的原油性质预测方法及系统，使用已知基础数据与预设数据库执行物性相似度匹配操作获得第一目标数据基础上，通过判断参考性质曲线是否满足预设曲线规则获得第二目标数据，再对第二目标数据进行预切割从而获得贴近使用场景的预测数据，将原油基础数据、原油评价实验数据通过特定的处理后，形成可供切割工具切割计算的基础数据，并做为数据源进行存储，再利用预切割所得结果进行测试验
