Petroleum wellhead instrument mounting component

Abstract

The invention provides a petroleum wellhead instrument mounting component. The petroleum wellhead instrument mounting component comprises a mounting pipe body. Wherein two ends of the mounting pipe main body are respectively connected with the oil pipe, and the length of the mounting pipe main body is not less than the length requirement that the pressure gauge, the thermometer, the pressure transmitter and the temperature transmitter are simultaneously mounted according to the mounting standard. And the pressure gauge, the thermometer, the pressure transmitter and the temperature transmitter are detachably and uniformly arranged on the mounting pipe main body at intervals according to the mounting standard. According to the installation component, a pressure gauge, a thermometer, a pressure transmitter and a temperature transmitter can be installed at the same time according to standard specifications, installation, disassembly, maintenance and inspection of instruments are easy to achieve, data errors can be reduced through standard specification installation of the instruments, and the installation efficiency is improved. Reliable data support is provided for production and operation decisions, and potential safety hazards of production are reduced.

Description

technical field [0001] The invention belongs to the technical field of oil and gas production, and in particular relates to an oil wellhead instrument installation component. Background technique [0002] After realizing the remote monitoring of oil and gas production on-site data, developers found that there were problems with the wellhead temperature of many wells when using the collected data. The No. 1 Oil Production Plant checked the on-site well temperature transmitters of 755 wells one by one, and found that 122 of the temperature transmitters were not properly installed. The main reasons for the improper installation of the temperature transmitter are as follows: the installation hole is inclined, the watch rod is short, the installation hole is blocked, the thread is embroidered, the watch rod is embroidered, and the thermometer does not match the thread of the mounting base. [0003] At present, the wireless pressure transmitter and temperature transmitter are ins...

AI Technical Summary

Problems solved by technology

The main reasons for the improper installation of the temperature transmitter are: the installation hole is inclined, the meter stem is short, the installation hole is blocked, the thread is embroidered dead, the meter stem is embroidered dead, the thermometer does not match the screw thread of the installation base, etc.

[0003] At present, the wireless pressure transmitter and temperature transmitter are installed on the short joint of the oil pipe with a length of 43cm back pressure pipeline. The head of the meter is skewed, which leads to large errors in the measurement data; the nipple of the tubing is too short, so only pressure transmitters and temperature transmitters can be installed. Affected by the harsh environment of the Tahe Oilfield, the transmission instruments frequently fail and require daily maintenance. During the maintenance period, the pipeline pressure and medium temperature cannot be monitored and recorded, resulting in the inability to timely and effectively judge the abnormal conditions of the pipeline and production; The admission data caused a lot of inconvenience, as shown in the figure below

[0004] The above problems seriously affect the monitoring of wellhead temperature and back pressure and the reading of data. There is a large deviation in the wellhead temperature and pressure data monitored by PCS (Production Command System), which seriously affects production and operation decision-making and has certain hidden dangers in production safety.
