Abstract

The invention provides a monitoring apparatus and a transmission apparatus of high-temperature production well pump temperatures and pressures, and a system. The system comprises two discrete apparatuses, namely the monitoring apparatus of high-temperature production well pump temperatures and pressures and the transmission apparatus of high-temperature production well pump temperatures and pressures; the monitoring apparatus is used for measuring the temperatures and the pressures of an underground oil reservoirs and sending the temperatures and the pressures to the transmission apparatus in the form of ultrasonic wave signals; the transmission apparatus receives the ultrasonic wave signals and generates acoustic signals for loading on an oil pipe and sending out; compared with a direct-reading pressure gage, the process of cable tying during construction is avoided, the construction difficulty and the construction risk are reduced, and the launching intervals of an ultrasonic emitter and an electroacoustic transducer can be adjusted according to requirements, and therefore, the monitoring apparatus and the transmission apparatus also are capable of meeting the requirements of instantaneity. Besides, the monitoring apparatus and the transmission apparatus both are provided with thermal insulating elements and are capable of well adapting to high-temperature working environments.

Description

technical field [0001] The invention relates to the technical field of oil well temperature and pressure monitoring, in particular to a temperature and pressure monitoring device, transmission device and system under a high-temperature production well pump. Background technique [0002] In the process of oilfield development and production, the data acquisition of production wells has important guiding significance for the formulation of oil and gas well development and production plans. Therefore, in the production activities of oilfield production wells, the recording of parameters such as pressure and temperature of production wells is generally carried out. [0003] It is the most common form to use storage pressure gauges to record production well data. Its characteristic is that the pressure gauge is installed under the pump, and it is lowered into the production well along with the pump. The pressure gauge monitors the pressure and temperature changes of the product...
