Description

Technical Field

[0001] This invention relates to the field of oil and gas production technology, specifically to an online moisture meter installation device. Background Technology

[0002] In the process of oil production and management, real-time monitoring of changes in crude oil water content is crucial for dynamic analysis of oil wells, control of the operational status of oil station facilities, and assurance of the quality of exported crude oil. However, due to factors such as radioactivity, unstable measurement results, excessive size, and high cost, traditional online automatic crude oil water content analyzers have not been widely adopted in the oil and petrochemical production industry.

[0003] Manual sampling and testing is currently the most common method for water cut detection in oilfields. Whether at the wellhead or in the pipeline, oil samples need to be manually extracted and analyzed in the laboratory regularly. The measurement process involves procedures such as water bath heating, rough water cut measurement with a graduated cylinder, centrifugation, and manual calculation. Analyzing a single sample is time-consuming, and the sample volume is very small compared to the volume of liquid flowing through the pipeline, resulting in poor sample representativeness.

[0004] The online water content analyzer utilizes the different absorption rates of high-frequency electromagnetic waves by oil and water. Because water's dielectric constant is much greater than that of oil, its absorption rate of high-frequency electromagnetic waves is significantly higher. By measuring the electromagnetic wave energy in the electromagnetic resonant cavity probe, the water content in crude oil can be determined through data processing and analysis. The sensing probe employs a high-frequency electromagnetic resonant cavity structure. This structure features concentrated electromagnetic wave energy within the probe, good signal stability, resistance to wax formation, and immunity to the effects of oil-in-water or water-in-oil emulsions. The excitation signal uses a 1GHz high-frequency signal. A 1GHz signal source has a small frequency broadening, and the water salinity has minimal impact on the detection results at this frequency.

[0005] However, while this type of online water content analyzer has many advantages, it requires accurate installation to ensure that the sensor probe is in full contact with the oil and water in the oil and gas pipeline, thus guaranteeing the accuracy and precision of the measurement. At the same time, the tilt angle of the sensor probe in the oil and gas pipeline will directly affect the degree of adhesion of crude oil to the sensor probe. Ensuring the installation accuracy of the online water content analyzer is crucial to prevent blockage of the oil and gas pipeline. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an online moisture meter installation device.

[0043] 1. The positioning base of the present invention can effectively ensure the stability of the center positioning position of the positioning base through the synchronous lifting of the first, second and third positioning parts. When the installation equipment is positioned on the branch pipe of the oil and gas pipeline, it can effectively ensure that the axis of the installation equipment coincides with the axis of the branch pipe of the oil and gas pipeline, thereby ensuring the installation position of the online moisture meter.

[0044] 2. The sliding guide in this invention has a triangular guide rail with a triangular structure, so that the oblique guide surfaces on both sides of the equilateral triangle cross section of the triangular guide rail are symmetrically arranged, so that the bottom guide wheels of the slide blocks that are slidably supported on the two oblique guide surfaces can be automatically aligned, thereby ensuring the stability of the axis center of the first and second slide blocks when the online moisture measuring instrument is moved.

[0045] 3. The sliding clamping part in this invention has an arc-shaped support part with an arc-shaped end face. By rotating the arc-shaped support part, the circumferential rotation of the online moisture meter held by the sliding clamping part can be achieved while keeping the axis fixed. This allows for adjustment of the corresponding installation positions of the bolt holes of the meter flange and the pipe flange. Attached Figure Description
