Abstract

The invention relates to the technical field of crude oil on-line dynamic measurement, in particular to a crude oil moisture content on-line detection device capable of separating solid and gas impurities. The technical problem to be solved is to provide the on-line detection device capable of separating the solid and gas impurities for the moisture content of the crude oil, which is convenient for separating the solid and gas impurities in the crude oil and improving the measurement precision of the moisture content. According to the technical scheme, the device comprises an outer shell, a cover plate, an oil well pump, an input pipeline, an output pipeline, a first electromagnetic ball valve and the like, the cover plate is arranged at the top of the outer shell, the oil well pump is installed in the outer shell, the input pipeline and the output pipeline are arranged on the oil well pump, and the output pipeline penetrates through the outer shell to be communicated with a petroleum pipeline; and a first electromagnetic ball valve is arranged on one side of the output pipeline. The influence of solid and gas impurities in crude oil on a final measurement value in the measurement process of the water content of the crude oil is solved through the solid-gas separation mechanism, and online real-time dynamic measurement of the water content of the crude oil is realized through the detection mechanism.

Description

technical field [0001] The invention relates to the technical field of on-line dynamic measurement of crude oil, in particular to an on-line detection device for water content of crude oil capable of separating solid-gas impurities. Background technique [0002] The water content of crude oil refers to the amount of water present in crude oil, expressed in mass fraction. As a large number of oilfields in my country are exploited in the middle and later stages, oil well production fluids are generally crude oil with high water content, and the water content value is an important parameter for formulating subsequent oil production, transportation and trading plans. Therefore, real-time and accurate measurement of the water content of crude oil is very important. important. [0003] Among the many methods of measuring the water content of crude oil, the advantage of the microwave method is non-contact measurement, which prevents the crude oil from causing corrosion damage to th...
