Description

Technical Field

[0001] The utility model relates to the technical field of oil field testing, and in particular to an Internet of Things intelligent dynamic liquid level monitoring device. Background Art

[0002] The dynamic liquid level of an oil well is an important indicator of the fluid supply capacity of the oilfield formation. Timely mastering of the dynamic liquid level and reasonable adjustment of the submergence of the oil pump to stabilize the suction pressure of the oil pump within a reasonable range are important measures to improve the working efficiency of the oil well, ensure stable production of the oil well, and save energy and reduce emissions.

[0003] In the field of low-pressure testing of domestic oil and gas fields, for many years, various instrument manufacturers have not made any essential breakthroughs in technology and testing methods, and the testing methods and processes are basically the same. Around 2000, some manufacturers gradually changed the thermal paper recording method to data storage and display; after 2010, due to safety and other reasons, various instrument manufacturers eliminated the gunpowder acoustic bomb firing mode that had been used, and changed it to high-pressure nitrogen or casing gas firing, digital storage, and software automatic analysis. This testing mode has continued to this day.

[0004] The low-pressure test work on site requires at least two people to complete. The equipment is bulky and has low intelligence. The settings of various instrument parameters are all manually operated by testers, which requires personnel to have high field testing experience. The test data is stored in portable instruments, and the security and timeliness cannot be effectively guaranteed. Sometimes it takes a lot of time to find the well location on site. The data of the field test needs to be transferred to the computer in time after the tester returns from the well site, and then manually analyzed, sorted and calculated by the data analyst, and then a data report is formed and uploaded to the database or printed. The entire test and analysis process has low work efficiency, and the accuracy of the data depends entirely on the responsibility and professional level of the test and analysis personnel.

[0017] Based on the working principle of echo reflection, the instrument is installed at the test wellhead through the thread 11, and the air chamber 6 is deflated to generate a sound wave pulse. When the test sound wave pulse propagates in the gas medium, it will generate a reflection pulse when it encounters the phonetic symbol, the joint hoop and the liquid surface. The sound pulse is received by the micro-phone 9 and converted into an electrical signal. The control circuit in the explosion-proof tablet computer 12 performs digital processing, and the propagation speed of the sound wave pulse and the reflection time of the reflection pulse can be accurately measured, thereby obtaining the distance between the liquid surface and the wellhead. The test results and curve graphics are stored in the data storage of the control circuit. The communication function of the control circuit can be used to transmit the test results and curve graphics to the explosion-proof tablet computer 12 by wired or wireless communication, and then transmitted to the computer in the oilfield control center through the 4G network.
