Abstract
Provided is a gas-liquid two-phase liquid flow measuring device. Crude oil extracted from the underground of oil fields contains a lot of gas and is gas-liquid two-phase mixture. Currently, most oilfield operation is completed by adopting such a conventional method that crude oil is separated into gas-phase flow and liquid-phase flow via a liquid-gas separator and then the liquid-phase flow is measured by using a common liquid flowmeter. However, the gas-liquid two-phase liquid flow measuring device is capable of directly measuring the liquid flow in crude oil extracted from the underground. The gas-liquid two-phase liquid flow measuring device comprises a liquid flowmeter (1) which has a front end with a front cavity (2) and a rear end with a rear cavity (3). The front cavity and the rear cavity are connected via a gas pipe (4). A floater (5) is disposed at the upper portion of the front cavity at a position corresponding to a gas hole of the gas pipe. The gas-liquid two-phase liquid flow measuring device of the utility model is applied for measurement of gas-liquid two-phase liquid flow.
Description
Technical field:
< b TranNum=" 74 ">the utility model relates to a kind of novel liquid flow measurement device, is specifically related to a kind of vapour-liquid two-phase fluid flow measurement mechanism that is used for petroleum pipe line.</b>
Background technology:
A large amount of gas is contained in < b TranNum=" 78 ">from the crude oil of down-hole, oil field extraction; It is the vapour-liquid two-phase mixture; The traditional method in oil field is to adopt liquid-gas separator that crude oil is separated into gas phase and liquid phase mostly at present, detects the flow of liquid phase again with common liquid flowmeter.And vapour-liquid two-phase fluid flow measurement mechanism can directly be measured the flow of liquid in the crude oil of down-hole extraction.Vapour-liquid two-phase fluid flow measurement mechanism compare with the tradition liquid-gas separator that adopts have continuous on-line measurement, unmanned, compact conformation floor area are little, invest characteristics such as little maintenance cost is low.</b>
Summary of the invention:
The purpose of < b TranNum=" 82 ">the utility model provides a kind of vapour-liquid two-phase fluid flow measurement mechanism of measuring fluid flow in the vapour-liquid two phase petroleum mixtures.</b>
Above-mentioned purpose realizes through following technical scheme:
< b TranNum=" 86 ">vapour-liquid two-phase fluid flow measurement mechanism; Its composition comprises: liquid flowmeter; Described liquid flowmeter front end has preceding cavity; Described liquid flowmeter rear end has back cavity, and described preceding cavity is connected through snorkel with described back cavity, and float is equipped with in the described preceding position corresponding with the air hole of snorkel, cavity top.</b>
< b TranNum=" 88 ">described vapour-liquid two-phase fluid flow measurement mechanism, described preceding cavity has the described air hole that communicates with described snorkel with cavity top, described back.</b>
< b TranNum=" 90 ">described vapour-liquid two-phase fluid flow measurement mechanism, described preceding cavity top has the carriage of holding described float.</b>
Beneficial effect:
1. the utility model is worked as the few liquid of gas for a long time, and liquid level rises in the entrance point cavity, the float come-up, and float is blocked air hole,
Liquid can not flow through from snorkel and guarantee measuring accuracy.
