Transfer synchronizing mechanism of high-temperature and high-pressure formation fluid analysis meter

Abstract

The invention provides a transfer synchronizing mechanism of a high-temperature and high-pressure formation fluid analysis meter. The transfer synchronizing mechanism comprises two high-precision motors (1-1 and 1-2), two high-precision right-angle speed reducers (2-1 and 2-2) connected with the two high-precision motors (1-1 and 1-2) respectively, a host A (3) connected with the high-precision right-angle speed reducer (2-1), a host B (4) connected with the high-precision right-angle speed reducer (2-2), a metal high-pressure line (5) used for connecting the host A (3) and the host B (4), a synchronizing controller (7) connected with the high-precision motor (1-1) and the high-precision motor (1-2), and synchronous control cables (6) used for being connected with the two high-precision motors (1-1 and 1-2) and the synchronizing controller (7) respectively. The high-precision servo motors and the high-precision right-angle speed reducers are adopted, so that the feeding quantity of the host A and the supplementary quantity of the host B are controlled to be consistent, and pressure is also stabilized.

Description

technical field [0001] The invention relates to a sample transfer synchronization mechanism of a high-temperature and high-pressure formation fluid analyzer, belonging to the technical field of fluid analysis. Background technique [0002] The formation fluid analyzer is mainly used to measure the phase characteristics of black oil, heavy oil, natural gas, condensate gas and volatile oil. It directly observes the oil and gas changes of formation oil and gas under different temperature and pressure conditions through a container with a transparent observation window. A complete set of analysis and test data is calculated and sorted out through the test processes of pressure measurement, isovolumic exhaustion test and differential condensation. Calculate the phase diagram according to the relevant software. [0003] The existing high-temperature and high-pressure formation fluid analyzer has the following disadvantages: when the existing high-temperature and high-pressure...

Problems solved by technology

[0003] The existing high-temperature and high-pressure formation fluid analyzer has the following disadvantages: when the existing high-temperature and high-pressure formation fluid analyzer transfers samples (the liquid sample is transferred from host A to host B) because it is a DC motor, it is manually controlled by two hosts The rotating speed and speed must not be synchronized, which will make the pressure of the main engine unstable and the liquid will cause degassing
