Problems solved by technology

However, due to the incomplete separation of existing oil, gas and water, the measurement results have large deviations
The surface technology of oil production wells in some oilfields adopts ring line oil collection or scattered oil wells, and conventional single well fixed metering devices cannot meet the demand
In addition, the current single well metering process has no output gas metering, especially for oil wells containing hydrogen sulfide, wellhead operations such as wellhead sampling and packing replacement have the risk of hydrogen sulfide poisoning

Abstract

The invention provides a multi-parameter mobile measuring device for oil well output liquid. The multi-parameter mobile measuring device comprises a liquid inlet pipe; a jet pump connected with the liquid inlet pipe; a separation tank provided with an electric flocculation device; a flash tank communicated with the bottom of the separation tank through a water pipe, wherein a second oil pipe is connected to the bottom of the flash tank and connected to a second oil storage tank; an electric heater arranged on the water pipe and used for heating the liquid in the water pipe to over 100 DEG C; and a condenser communicated with the flash tank through a flash pipe, wherein the outlet end of the condenser is connected with a condenser pipe, and a water flow meter is arranged on the condenser pipe. According to the embodiment of the invention, the oil-water metering is more accurate.

Description

technical field [0001] The invention relates to the technical field of oil and gas production, in particular to a multi-parameter mobile measuring device for oil well output fluid. Background technique [0002] In the process of oilfield production and development, the measurement of the output fluid volume and water cut analysis (sampling and testing) are necessary requirements for monitoring the production status of oil wells. Different metering methods and manual sampling, distillation and testing of water content have certain error effects, but they can meet the basic production status analysis of oil wells. [0003] With the improvement of refined management of oilfield production and the deepening of production analysis, the importance of real-time recording and analysis of oil well production status is increasing. However, due to the incomplete separation of existing oil, gas and water, the measurement results have large deviations. The surface technology of oil pro...
