An automatic sampler for petroleum liquid comprehensive samples

Abstract

The invention discloses an automatic comprehensive petroleum liquid sample sampler. The automatic comprehensive petroleum liquid sample sampler comprises an oil sample storage barrel, a water bath barrel, an anti-explosion heating pipe, an anti-explosion temperature controller, oil sample circulating pipes, a stainless steel circulating pump, an anti-explosion distribution box and an anti-explosion motor, wherein the oil sample storage barrel is arranged in the water bath barrel; the top of the oil sample storage barrel is provided with two oil sample circulating pipes and an oil sample inlet connected with an oil sample input pipe; the water bath barrel is internally provided with the anti-explosion heating pipe which is positioned below the oil sample storage barrel; the outer bottom of the water bath barrel is provided with the anti-explosion temperature controller; the stainless steel circulating pump is positioned at one side of the water bath barrel; the anti-explosion motor is connected with the stainless steel circulating pump; the oil sample input pipe is provided with a timing distribution valve. The petroleum liquid comprehensive sample automatic sampler has the advantages that the structure is reasonable; the labor intensity is low; the testing accuracy of water content conditions of offshore crude oil convergence and transportation is improved; errors for handing over and taking over the crude oil convergence and transportation are reduced; the safety and the environment protection in the crude oil sampling process are ensured.

Description

Technical field [0001] The invention belongs to the technical field of offshore oil exploitation, in particular to an automatic sampler for comprehensive samples of petroleum liquids. Background technique [0002] With the continuous expansion of the field of offshore oil exploration and the increase in the number of offshore platforms, the analysis and research of crude oil sampling and transportation is particularly important. The existing crude oil gathering and transportation sampling is mainly carried out by manually setting the interval time to take the average data value for analysis. Due to the influence of subjective factors such as workers’ sense of responsibility and the length of the interval time, the oil samples taken cannot fully reflect the actual situation, resulting in crude oil The water cut analysis is inaccurate and the crude oil gathering and transportation volume has errors. Summary of the invention [0003] The problem to be solved by the present invention...
