Abstract

The invention relates to a high-temperature high-pressure stratum crude oil physical property analysis system. The innovation points of the invention reside in that, the system comprises an analysis cylinder, and a pull rod type piston is arranged in a cylindrical shell; the analysis cylinder comprises a swing stirring system which drives reciprocate swing of the analysis cylinder, a main pump pressure adjusting and driving mechanism, which drives the pull rod type piston in the analysis cylinder to move at an axial direction in order to adjust volume, and a main pump magnetic stirring mechanism, whose magnetic stirring impeller is rotated, wherein the rotation is driven by torque transmitted from a main pump agitator motor, a main pump decelerator, a rotary long rod and a main stirring magnet in order. The invention has the advantages that: the analysis cylinder has a two in one structure, and the analysis cylinder can be used for accommodating, testing and analyzing crude oil, simultaneously is used for driving the pull rod type piston to move by the main pump pressure adjusting and driving mechanism, in order to control the pressure and the volume change, and thereby realizing direct and precise measurement and recording of samples in the analysis cylinder by cooperation of a double-stirring system composed of the swing stirring system and the main pump magnetic stirring mechanism.

Description

technical field [0001] The invention relates to an analysis system, in particular to a system for analyzing the physical properties of high-temperature and high-pressure formation crude oil. Background technique [0002] The physical property analysis of formation crude oil is to test the constant mass expansion experiment, single degassing experiment, multiple degassing experiments and multi-stage viscosity measurement of formation fluid samples under formation temperature conditions; obtain the relationship between volume and pressure change, saturation pressure, compressibility coefficient , Formation crude oil viscosity, formation crude oil density, original dissolved gas-oil ratio and volume coefficient and other high-pressure physical parameters, and at the same time, it can simulate the multi-stage degassing and multi-stage viscosity measurement of oil-gas separation state due to pressure drop during formation fluid production, etc. process and data. It provides im...
