Gas well testing safety monitoring and controlling technology

Abstract

The invention relates to a gas well testing safety monitoring and controlling technology. The gas well testing safety monitoring is that data, such as pressure, temperature and oil, gas and water yield of a well mouth, a throttling testing manifold, a heater, a separator and the like can be monitored in real time and automatically collected and recorded by a data acquisition system, and over-limit alarm is realized; the real-time monitoring, the automatic acquisition, the data recording and the over-limit alarm of harmful gases, such as hydrogen sulfide, carbon dioxide and methane in well site air are realized; and real-time video monitoring in field and the like can be realized. The gas well safety monitoring and controlling technology disclosed by the invention aims to carry out pressure, temperature and flow monitoring and automatic alarm on the well mouth, a casing pipe hohlraum, an upper and lower flow of an oil nozzle, a heater, a separator and toxic, harmful gas and the like, whole-area video area monitoring is realized, the field technology measure is guided, multiple parameter curves are displayed in the same screen, data is synchronously printed and drawn, and therefore the data is safely monitored and completely and accurately obtained.

Description

Technical field: [0001] The invention relates to a gas well test safety monitoring and control technology, which belongs to the technical field of petroleum exploitation. Background technique: [0002] Due to the irrationality of safety monitoring and control technology, the existing gas well testing safety monitoring and control technology has the following difficulties: (1) the safety monitoring function and safety monitoring technology measures must be reasonable and reliable; (2) how to Throttling pressure drop distribution, heating, and dosing can effectively prevent ice blockage; (3) How to automatically relieve pressure when the ground process is overpressured, and how to safely and effectively implement deblocking when ice blockage occurs, so as to ensure the safety of the ground process and The test was carried out smoothly; (4) How to ensure the safety of personnel and equipment in the event of natural gas leakage; (5) How to realize the linkage between safety moni...
