Abstract

The invention provides an online tubing rod wear degree monitoring device and an online tubing rod wear degree monitoring method which are used for online monitoring of eccentric wear degree of a tubing rod at an oil wellhead. The online tubing rod wear degree monitoring device and the online tubing rod wear degree monitoring method have the advantages that through acquisition, conversion and remote transmission of total iron ion concentration data, reliable data are provided for production management, test results are instructive to oil well production management, loss caused by high-frequency operation of an oil well due to tubing rod wear can be avoided, and tubing rod replacement and well repair expenses and operation costs are reduced; failure in monitoring oil well tubing rod wear in real time currently is overcome, and the iron ion concentration of oil well production materials measured on line is converted into current signals so as to achieve remote transmission of the data; success in real-time monitoring of tubing rod wear degree provides technical support for anti-eccentric measures of oil fields; the online tubing rod wear degree monitoring device is low in cost and wide in measurement range and is hopefully popularized and applied in well sites of the oil fields massively.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to an on-line monitoring device and a monitoring method for the wear degree of oil pipe rods, which are suitable for directional wells or oil wells with relatively large well inclinations. Background technique [0002] The wellbore trajectory of directional wells is complex. With the prolongation of development time, the problem of eccentric wear of pipes and rods is becoming more and more serious, resulting in the increasing number of high-frequency well operations. Under the new situation, the operating costs are increased. At present, various degrees of eccentric wear problems have been found in the developed oilfields in my country, but in the current oil exploitation industry, there is no technology for online monitoring of the degree of eccentric wear of pipes and rods during oil well production. Observe and judge the degree of wear of tubing rods, so...
