Underground parameter measurement monitoring system

Abstract

The invention relates to an underground parameter measurement monitoring system. The underground parameter measurement monitoring system comprises a main body, wherein a protective sleeve sleeves themain body; the lower end of the main body is in butt joint with a sensor short section; the sensor short section is divided into a sensor short section upper section and a sensor short section lower section; an outer barrel sleeves the sensor short section; the upper end of the outer barrel is in butt joint with the lower end of the protective sleeve; the lower end of the sensor short section lower section is connected with a bypass short section; the lower end of the outer barrel is in butt joint with a signal conversion short section; the lower end of the signal conversion short section is in butt joint with an instrument outer barrel; and a probe outer barrel is arranged in the instrument outer barrel. The underground parameter measurement monitoring system has the beneficial effects that the working condition of an underground drilling tool is monitored in real time, the underground drilling working condition is mastered in time, accidents are avoided or reduced, the economic lossis reduced, and the exploration and development process is accelerated.

Description

technical field [0001] The invention relates to a downhole parameter measurement and monitoring system, which belongs to the field of petroleum and natural gas extraction. Background technique [0002] Due to the concealment and complexity of the drilling process, downhole accidents occur frequently in deep wells and ultra-deep wells in complex formations, which seriously restricts the exploration and development of oil and gas fields and causes huge economic losses. In the process of oilfield exploitation, the monitoring and automatic control of on-site projects are indispensable for safe and economical operation, and it is necessary to measure the temperature and pressure of the downhole in time. In particular, in the pilot test and field project test of petroleum thermal recovery, since the temperature and pressure at the bottom of the well are very high, it is necessary to continuously measure and read the downhole temperature and pressure. Due to the high requirements ...

AI Technical Summary

Problems solved by technology

[0003] With the development of measurement-while-drilling technology, the development and research of downhole parameter measurement systems have been carried out at home and abroad, and the measurement of single parameters such as well deviation, azimuth, and pressure has been realized, and there are problems such as unstable downhole work and poor field applicability.

Copilot, NDS and other systems developed and promoted by foreign companies have achieved good results in field application, but these foreign technologies are currently refused to be sold to my country
