Description

TECHNICAL FIELD

[0001] The utility model relates to a detection device, in particular to a multi-probe water content rapid detection device. BACKGROUND

[0002] Water content, as an important parameter of crude oil, is a key data in oilfield production. The accuracy of water content detection results will directly affect the determination of water and oil layer position, the calculation of crude oil production, the prediction of oil well development life and other oil reservoir production and development work.

[0003] At present, the petroleum and petrochemical industry often uses a crude oil water content tester for sampling and analysis of oil samples. The automatic layered detection crude oil water content analyzer disclosed in the publication CN212111419U includes a workbench, a water content probe and a display. An electric push rod, a detection container and a control system are respectively installed on the workbench. The height of the detection container is 200mm-250mm. The piston rod of the electric push rod is vertically upward. A connecting bridge is installed on the upper end of the piston rod of the electric push rod. The water content probe is vertically downward and fixedly installed on the connecting bridge. The detection container is located on the rotation track of the water content probe. The electric push rod and the water content probe are respectively electrically connected with the control system. The electric push rod drives the water content probe to move downward step by step under the control of the control system, realizing layer-by-layer detection of the water content of the oil sample. The control system calculates and displays the layer-by-layer detection data of the water content of the oil sample.

[0004] This water content analyzer has the following problems:

[0005] 1. The detection container of the device is fixed on the workbench and cannot be moved. After one detection is completed, the sample of the previous detection is discharged through the valve. The detection container is easy to leave water marks of the sample of the previous detection, which makes it difficult to ensure the accuracy of the water content detected in the next detection.

[0006] 2. The device can only detect one oil sample at a time, and manual intervention is required. The entire detection process cannot be fully automated. After each detection is completed, the laboratory technician needs to manually discharge the sample through the valve and re-pour the sample, which greatly increases the detection time, the detection efficiency is very low, and it cannot meet the needs of large-scale centralized testing.

[0013] As a further preferred embodiment, the probe at the lower end of the moisture content sensor includes an insulating cover with multiple detection metal pillars distributed circumferentially on the insulating cover to improve the stability and accuracy of moisture content signal detection.

[0014] As a further preferred option, a temperature sensor is also provided inside the insulating cover to detect the temperature of the oil and transmit it to the controller, thereby compensating for the detected water content signal.
