In the normal production process of pumping well, the measured liquid level depth in the annular space of tubing and casing is called dynamic liquid level. The purpose of the test is to know the level of the oil well. In the process of oilfield exploration and development, continuous and real-time monitoring of liquid level dynamic data is helpful to analyze the relevant parameters of the formation and provide relevant guidance for the next step plan of oil production wells. The automatic liquid level monitoring instrument produced by our factory can provide reliable guarantee for the improvement of liquid level parameters in oilfield production.
Using the principle of infrasonic echo logging, combined with special filtering technology and low-frequency fuzzy automatic identification algorithm, the dynamic liquid level tester can automatically locate the position of liquid level and hoop wave, so as to realize the measurement of liquid level depth. By releasing a small amount of casing gas instantaneously, the gas at the wellhead of oil casing annular space generates expansion shock wave. The infrasonic wave component in the acoustic wave propagates along the ring to the downhole. The reflected acoustic wave generated by coupling, sound mark and gas-liquid interface acts on the micro acoustic transducer and converts into electrical signal. The electrical signal presents the liquid level that can be identified after digital processing such as amplification, filtering and A / D conversion Curve.
The product can realize continuous on-line monitoring of liquid level depth under various well conditions such as killing well and no killing well; according to the installation mode, the product can be divided into mobile and fixed type; according to the data transmission mode, it can be divided into wired transmission and wireless transmission.
