1. A method for measuring composition and property of formation fluid, comprising:
acquiring a measuring model used for measuring a composition and a property of a formation fluid;
using a signal measured by a sensor on a downhole hydrocarbon formation tester in real-time as input data and inputting the input data into the measuring model;
processing the input data by the measuring model; and
directly outputting a processing result as data on the composition and the property of the real-time formation fluid, or parsing the data on the composition and the property of the real-time formation fluid according to the processing result;
wherein acquiring the measuring model used for measuring the composition and the property of the formation fluid comprises retrieving a pre-created and pre-trained measuring model, or creating and training the measuring model in real-time.
