Automatic measuring device for water content of wellhead liquid and measuring method thereof

Abstract

The invention discloses an automatic measuring device for the water content of the wellhead liquid and a measuring method thereof. The device includes a material pipe, a high-pressure self-priming pump, a measuring cavity, a buffer tank, a detector and a jet pump, wherein the material pipe is connected with the high-pressure self-priming pump, the high-pressure self-priming pump is connected withthe measuring cavity, the measuring cavity is disposed at the bottom of the buffer tank, the measuring cavity is in communication with the bottom of the buffer tank, the detector is disposed in the buffer tank and the measuring cavity in a penetration mode, a probe of the detector extends to the measuring cavity, and the jet pump is connected with the buffer tank. The device is advantaged in thata problem that measurement of the water content of the produced liquid at a wellhead of an oil well is difficult in the prior art is solved, the purpose of data measurement of the water content of theproduced liquid is realized, and working efficiency of measuring the crude oil output rate is improved.

Description

technical field [0001] The invention relates to the technical field of oil recovery in oilfields, in particular to an automatic measuring device for the water content of wellhead fluid and a measuring method thereof. Background technique [0002] At present, in all oil production wells in the world, oil production rate and oil production volume are the most important basic data of oil field production. Most oil fields in my country adopt secondary and tertiary oil flooding operations, and secondary oil recovery adopts water flooding technology. Three-element compound flooding technology is used for tertiary oil recovery. Daqing Oilfield, Jilin Oilfield, Tarim Oilfield, Shengli Oilfield and other large oilfields in China often use similar technologies for deep oil recovery due to aging oilfields. [0003] Under the conditions of secondary and tertiary flooding operations, the produced product is a three-phase flow (gas phase, water phase, oil phase), and the possible componen...
