Well depth measurement is one of the logging engineering techniques, specifically the measurement of the liquid depth of the well using logging tools.
In order to understand the oil supply capacity of oil wells and master the production dynamics, it is a regular task to measure the liquid level of oil wells. Therefore, in the logging process, the accuracy and reliability of the depth system is critical to obtaining high-quality logging data, which often depends on the accuracy of the depth measurement method. Currently used depth measurement methods include wireline logging depth and Martin Dyke depth measurement system logging depth.
Logging referred to in the petroleum industry is a process of recording the measured parameters as a function of depth as the logging instrument passes through different rock formations. Logging is a component of oil and gas reservoir engineering. It involves oil physics, storage properties, fluid properties, computer technology, testing processes and instrumentation. It is the main technical means for exploration and development of oil and gas fields. Nowadays, logging technology has been an indispensable means for accurately identifying oil and gas reservoirs and accurately describing oil and gas reservoirs. Well logging data is an important basis for oil and gas reserves parameter calculation, capacity assessment and development and adjustment of development plans. From the point of view of logging, logging can be divided into two types: cable logging and logging while drilling. Wireline logging is done in its own wells. It is a common logging method at present; LWD, as the name implies, is completed with the drilling process.
Among many logging techniques, measuring the oil well depth and the pumping unit's power map are the two most commonly used logging techniques in oil production.
