Problems solved by technology

However, at present, the data collection in the pipeline is still a difficult point. The main reason is that the downhole pipeline is long, the pressure is not balanced, and the situation is changeable, which leads to inaccurate data collection, often causes false alarms, and leads to unnecessary waste of human resources.

Embodiment Construction

[0015] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0016] The pipeline pressure monitoring method provided by the present invention comprises the following steps:

[0017] Step 1: Install a number of pressure sensors at the horizontal pipes, longitudinal pipes and elbows, and set pressure sensors on the outer and inner walls of each elbow; ensure that at least three pressure sensors are installed on each horizontal pipe, and each longitudinal pipe Set at least three pressure sensors on it.

[0018] Step 2, collecting pressure sensor data according to a certain frequency, and recording the data of each pressure sensor separately.

[0019] Step 3: For each pressure sensor data, when the data collected by the press...

Abstract

The invention discloses a pipe pressure monitoring method, and the method comprises the steps: setting a plurality of pressure collection devices at a plurality of key points in a pipe, carrying out the spatial omnibearing monitoring, and eliminating errors in the time dimension through a corresponding calculation method. The data of the adjacent sensors can be employed for verification while thedata of the sensors is monitored to be abnormal, thereby reducing the errors and avoiding the false alarm. In addition, the method can achieve the triggering of an alarm when the accumulated number ofabnormality times reaches a certain value.

Description

technical field [0001] The invention belongs to the technical field of pipeline information collection and monitoring, and relates to a pipeline internal pressure monitoring method. Background technique [0002] With the advancement of technology, industrial systems usually rely on various types of automated information collection devices to achieve full-process monitoring. For example, use sensors, transmitters and other devices to record data such as wellhead pressure and oil temperature, and deal with abnormal conditions of wellhead equipment accordingly. However, at present, the data collection in the pipeline is still a difficult point. The main reason is that the downhole pipeline is long, the pressure is not balanced, and the situation is changeable, which leads to inaccurate data collection, frequent false alarms, and unnecessary waste of human resources. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a pip...
