The pressure measurement technology of casing and tubing refers to the technical means used to monitor the fluid pressure in the pipeline in the oil pipeline transportation system. It has important application value in pipeline engineering in the fields of oil and natural gas. Let’s take a detailed look at the oil pipeline transportation pressure measurement technology and its application in engineering.
First of all, the principle of casing and tubing transportation pressure measurement technology is to install pressure sensors or pressure gauges and other equipment on the pipeline to monitor the changes in fluid pressure in the pipeline in real time, and transmit the data to the monitoring system for processing and analysis. This technology can effectively grasp the operating status of the fluid in the pipeline, detect problems in time and take measures to ensure safe and stable pipeline operation.
In engineering applications, Casing and tubing's transmission pressure measurement technology is widely used in pipeline systems in the energy fields such as oil and natural gas. Its main applications include the following aspects:
Pipeline operation monitoring: By monitoring the pressure changes of the fluid in the pipeline in real time, we can understand the operating status of the pipeline, including parameters such as flow rate, flow rate, pressure, etc., and provide data support for pipeline operation management.
Leak detection: Casing and tubing delivery pressure measurement technology can be used to detect whether there are leaks in pipelines. When the fluid pressure in the pipeline changes abnormally, the system can promptly alarm and instruct operation and maintenance personnel to perform repairs and prevent leakage accidents.
Safety guarantee: By monitoring the pressure changes in the pipeline, abnormal conditions in pipeline operation, such as overpressure, pressure drop, etc., can be detected in time to ensure the safe operation of the pipeline system.
Data analysis and optimization: By analyzing the collected pressure data, pipeline operation strategies can be optimized, transportation efficiency improved, and energy consumption reduced.
In addition, oil pipeline transportation pressure measurement technology can also be combined with other monitoring technologies, such as temperature monitoring, flow monitoring, etc., to form a diversified pipeline monitoring system to further improve the level of pipeline operation and management.
Oil well pressure testing is a specialized test performed to accurately evaluate the productivity of oil wells and study reservoir parameters and reservoir dynamics. Conventional oil well pressure measurement technology usually uses wire trip downhole pressure gauges to conduct oil well pressure testing. However, this method has some shortcomings。
Disadvantages:
After the pressure measuring string is lowered into the well, it is necessary to inject oil layer cleaning agent, which increases the cost.
When measuring pressure in oil-heavy wells, the instrument is slowly raised and lowered, causing the pressure measuring wire to deform and the instrument to be blocked and unable to reach the actual testing depth.
Repeated operations of flushing the well or injecting other well fluids slow the recovery of formation pressure and may cause damage to the formation.
The current pressure measurement method can only obtain the instantaneous state after the pressure data is restored, and cannot comprehensively monitor the oil well pressure recovery process, nor can it observe the changes in formation pressure over time.
For heavy oil, extra heavy oil, and super heavy oil reservoirs, the success rate of conventional pressure testing is low.
Therefore, Casing and tubing pressure measurement technology plays an important role in this regard. It can obtain the pressure data in the pipeline in real time through online monitoring without going down the well, thus avoiding the above problems. This technology can improve the safety and stability of pipeline operations, reduce the risk of accidents, and is of vital significance to ensuring smooth and reliable energy transmission. With the continuous development and innovation of technology, oil pipeline transportation pressure measurement technology is expected to be more widely used and promoted.
