Abstract

The invention discloses a water content detector which comprises a detector outer tube, a detector inner tube is arranged in the detector outer tube, and an electrode group which enables two ends to generate different electric capacities according to different dielectric constants of crude oil and water is arranged in the detector inner tube. A thermistor for detecting the temperature of the crude oil and a photoelectric sensor for detecting the reflectivity of the crude oil are also arranged in the detector inner tube; and an electronic data processor for performing data analysis on the capacitance value transmitted by the electrode group, the temperature of the crude oil detected by the thermistor and the reflectivity of the crude oil is arranged on the detector outer tube. According to the water content detector, the water content in the crude oil in the detector inner tube is detected in real time through the electrode group, data is transmitted into the electronic data processor, the temperature of the crude oil in the detector inner tube is detected in real time through the thermistor, and the temperature of water in the crude oil is compensated through the auxiliary heating layer after analysis of the electronic data processor; and the dielectric constant of water in the crude oil is prevented from being changed due to a temperature difference.

Description

technical field

[0001] The invention relates to the technical field of oilfield exploitation, in particular to a water content detector. Background technique

[0002] In the process of oil extraction, the crude oil liquid extracted by the pumping unit is generally composed of crude oil, water and natural gas. After the natural gas in the crude oil liquid is separated, the water content of the crude oil will be tested to facilitate work. The personnel understand the water output data of the oil well, and based on these data, carry out digital oilfield construction such as estimating crude oil production, oil producing layers, predicting the development life of the oil well, controlling the production quality of the oil well, detecting the state of the oil well, and performing water injection operations.

[0003] However, most of the existing crude oil water content measurement methods are manual sampling measurement methods, and the results of manual sampling measurement are ...

Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] see Figure 1 to Figure 5 , the present invention provides a technical solution: a water content detector, including a detector outer tube 1, a detector inner tube 2 is arranged inside the detector outer tube 1, and a detector inner tube 2 is arranged according to the mediation between crude oil and water. The different electrical constants make the two ends produce electrode groups 3 with different capacitances. The inner tube 2 of the detector is also provided with a thermistor 4 for detecting the temperature of crude oil. The outer tube 1 of the detector is provided with a device for transferring the electrode group 3 The capacitance value and the electronic data processor 5 for data analysis of the crude oil temperature detected by the...
