An implantable heavy oil well sand monitoring device

Abstract

The invention relates to an implantable thickened oil well shakeout monitoring device which is characterized by comprising a fixing support. A motor is connected with the fixing support. A belt wheel is connected with the output end of the motor. The belt wheel is connected with the other belt wheel through a belt. The other belt wheel is connected with the top of a sand vibration exciter of an implanting device. An impeller is connected with the bottom of the sand vibration exciter. A flange plate is arranged on the upper portion of the sand vibration exciter. The flange plate is connected to an installation opening of a production pipeline in a sealing mode. Two vibration pickup machines extending downwards in a bending mode are arranged on the flange plate. A vibration sensor and an ultrasonic sensor are arranged on the upper portion of each vibration pickup machine. The vibration sensor and the ultrasonic sensor are respectively connected with a signal collecting instrument through signal cables. The signal collecting instrument is connected with a computer through a signal cable. Vibration signals and sound signals are collected by the signal collecting instrument and sent to the computer. Processed sand-carrying capacity and information of grain size change are given by the computer. The implantable thickened oil well shakeout monitoring device can be used in the production process of an oil field, especially a thickened oil field.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an implanted heavy oil well sand production monitoring device. Background technique [0002] In the process of oil and gas production, the problem of sand production is very common. A large amount of sand production or continuous sand production will cause sand burial in oil and gas layers, sand plugging in oil pipes, and sand accumulation in ground pipes, which seriously affect the normal production of oil and gas wells. Strict control of sand production will seriously affect productivity, and maintaining reasonable sand production can greatly increase oil well production. In order to adopt moderate sand production technology to ensure the maximum benefit of oil and gas wells, a technology and equipment capable of monitoring sand production in oil wells are needed. The current sand production monitoring devices mainly include acoustic measurement and electrical resistance method. The acou...

AI Technical Summary

Problems solved by technology

The sand production monitoring system of the resistance method is to insert a metal probe into the flow pipe, and the probe is covered by a corrosion-resistant sensitive metal element. The sand production information is obtained by sensing the change in impedance of the sensitive element after receiving sand erosion. Problems such as short service life and monitoring delay

[0003] For heavy oil fields, due to the high viscosity of crude oil, the signal generated by the natural impact of sand particles on the pipe wall is relatively weak, and it is difficult to monitor the change of sand content in oil flow, which is difficult to monitor
