Automatic adjusting system for underground flow regulator and operation method of automatic adjusting system

Abstract

The invention discloses an automatic adjusting system for an underground flow regulator and an operation method of the automatic adjusting system. A measuring short joint framework arranged at the upper end of a flow regulator anchoring mechanism is included and provided with a DSP, the DSP is connected with a sensor set and a motor assembly, and a signal conditioning and data collecting unit is arranged between the DSP and the sensor set. The sensor set is used for collecting air nozzle front-back pressure, temperature and air nozzle aperture parameters, the air nozzle front-back pressure, temperature and the air nozzle aperture parameters are sent to the DSP through the signal conditioning and data collecting unit, the DSP controls the motor assembly to adjust the aperture of an air nozzle through changing of the circulation area between a valve element and a valve base according to the received information, and automatic adjustment is achieved. The automatic adjusting system for theunderground flow regulator is utilized, flow regulator air nozzle adjustment can be finished only through one-time construction, later manual intervention and measurement are not needed, a large amount of manpower and a large number of material resources are saved, and the data tendency analysis can be effectively made in real time.

Description

technical field [0001] The invention belongs to the technical field of gas production in oil and gas fields, and in particular relates to an automatic adjustment system for downhole restrictors and an operation method thereof. Background technique [0002] In the process of natural gas extraction and production, movable and fixed downhole chokes with fixed choke nozzles are commonly used, and these chokes are purely mechanical. This traditional downhole choke cannot adjust the size of the choke nozzle in real time. It is necessary to shut down the well and use wire rope operations to replace the gas nozzles of different sizes to achieve different levels of throttling functions. This working method not only prolongs the operating time Time will affect gas well production, and will also increase construction costs, and the process is complicated, labor-intensive and time-consuming. Contents of the invention [0003] The technical problem to be solved by the present inventio...
