Description

Technical Field

[0001] The utility model belongs to the technical field of oil and water wells, and specifically relates to an oil and water well data recording instrument. Background Art

[0002] In the process of oilfield production monitoring and measurement, it is essential to measure the pressure value of oil and water wells, but ordinary pressure measuring devices have the following problems: 1. Since the pressure measuring device is often placed inside the oilfield, the pressure measuring device will be corroded by the oil over time, causing the pressure measuring device to be damaged and unable to continue to be used. 2. Ordinary oil and water well pressure measuring devices are integrated, and there are problems such as inconvenient reading of the pressure gauge, inaccurate pressure measurement, untimely pressure measurement, inconvenient recording, inconvenient installation and difficult disassembly. 3. When an ordinary pressure measuring device is measuring pressure, since one end of the pressure measuring device is connected to the oil and water pipe and the other end is suspended and not fixed, the gauge head will vibrate due to pressure or other external factors, resulting in inaccurate pressure measurement. Repeated pressure value measurement results in high labor intensity and reduced work efficiency for workers.

[0003] The utility model patent with announcement number CN 213039276 U discloses an oil and water well data recorder, including a shell, a pressure measuring joint, a sensor and a fixing mechanism. A groove is provided at the top of the pressure measuring joint, and a connecting hole is opened from the top of the groove to the bottom of the pressure measuring joint. The sensor is built in the groove. The device is novel in design and simple in structure. By providing an anti-corrosion layer on the outside of the shell, the pressure measuring device can be effectively prevented from being corroded by oil; by providing a signal acquisition module, a signal conversion module and a data transmission module, it is not only convenient for data transmission and observation, but also conducive to workers to record pressure values ​​in a timely and accurate manner; by providing a fixing mechanism, it is convenient for workers to regularly inspect and maintain the pressure measuring device and install and fix the pressure measuring device, reducing the labor intensity of workers and improving work efficiency.

[0004] However, the above device limits the pressure measuring device by the friction generated by the slider and the locking knob. This limiting placement makes the pressure measuring device unstable and easy to loosen. In addition, the above pressure measuring device only has one pressure sensor for pressure measurement, and multiple measurements are required to obtain accurate data. However, the pressure sensor in the above device is in direct contact with the oil. Long-term contact will cause corrosion to the pressure sensor and affect the working efficiency of the pressure sensor. In view of this, the present utility model is proposed. Utility Model Content
