A coring and sampling integrated sub, including an integrally formed base body, a probe module, a coring module and a hydraulic module. The probe module, the coring module and the hydraulic module are all mounted on the base body. The hydraulic module, the probe module and the coring module are sequentially arranged from top to bottom. An output end of the hydraulic module is configured to be connected to the probe module and the coring module, respectively. The hydraulic module is configured to provide telescopic power for the probe module, and provide power for movement, flipping, and pushing of the coring module. Also disclosed is a downhole instrument including the coring and sampling integrated sub.

Coring and sampling integrated sub and downhole instrument

Provided are a method and system for measuring a composition and property of a formation fluid. The method includes: 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.
