Single-well multiphase flow equipment state acquisition system

Abstract

The invention relates to the technical field of oil field data acquisition, and discloses a single-well multiphase flow equipment state acquisition system which is characterized in that an oil liquid output end of an oil extraction mechanism single well is connected with a multiphase flow state acquisition mechanism through an oil delivery pipe; a data transmitting end of a data acquisition card is connected with a remote display terminal in the hand of a worker through a wireless signal; and the multiphase flow state acquisition mechanism comprises a Doppler laser velocimeter, a throttling type flowmeter, a differential pressure sensor, an oil water content tester and a liquid level meter. Primary oil sequentially passes through the Doppler laser velocimeter, the throttling type flow meter, the differential pressure sensor, the oil water content tester, the liquid level meter and the like to be subjected to multiphase flow calculation of flow velocity, flow, differential pressure, water content and liquid level, decoding and displaying are carried out, and remote transmission of multiphase flow detection data is achieved. Therefore, remote detection and checking of the oil collection equipment and high quality are realized, and safe and efficient transmission and sharing of data are realized.

Description

technical field [0001] The invention relates to the technical field of oil field data acquisition, in particular to a single well multiphase flow equipment state acquisition system. Background technique [0002] Oil wells are perforations drilled by drilling methods. Generally, after the oil well is drilled into the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers. The hole gun shoots through the oil layer to form a channel, which is lowered into the oil pipe, and the oil is raised from the bottom of the oil well to the head of the well by a suitable induction method. Oilfield data acquisition is an essential equipment in oil extraction. Generally, each crude oil production well uses at least one oilfield data acquisition unit to pump out the oil hidden deep underground through the oil extraction pipe. [0003] When the oi...

Problems solved by technology

[0003] When the oil field is carrying out the oil production operation of a single well, it is often necessary to collect the status data of the initial oil collection of the oil production equipment, and a combination of various sensors and detection equipment is used to realize the high-quality monitoring of the initial oil. However, the common single well initial oil data is currently The data collected by the acquisition system is limited to simple flow velocity, temperature and humidity, etc., the phase flow of the collected data is single, and the data transmission uses data lines, which makes the remote transmission of signals inconvenient and the data analysis and data quality are not high, and the display is not intuitive enough.
