Abstract

The invention relates to a multiphase flow regulation device and a method for restraining slug flow by utilizing same. The multiphase flow regulation device comprises at least one basic unit, each basic unit comprises a front straight tube section and a rear straight tube section, a main bent tube with a bending angle at 180 degrees protrudes upwards and is arranged between the front straight tube section and the rear straight tube section, the main bent tube is connected with the front straight tube section via a front bent head with a bending angle at 90 degrees and connected with the rear straight tube section via a rear bent head with a bending angle at 90 degrees. The multiphase flow regulation device is reasonable in structure, the bending radius of the main bent tube is large, so that a wave-shaped tube is large in 'waving' range, and gas storage at the top of the main bent tube and generation of mixing effect are facilitated. By the aid of the straight tube sections for connecting the basic units, the total length of the multiphase flow regulation device can be adjusted conveniently, and the multiphase flow regulation device can be placed on a plane stably. The method for restraining slug flow by utilizing the multiphase flow regulation device is applicable to severe slug flow and hydraulic power slug flow, and is simple to operate without being allocated with extra hardware and software.

Description

Technical field

[0001] The present invention involves the field of stream flow in the sea oil and gas field development system. Specifically, it is a method of multi -phase current flow adjustment device and using its inhibitory segment flow.The segment stream refers to the strong segment plug and hydraulic segmentation flow. Background technique

[0002] The maritime oil and gas field development system usually includes 4 subsystems including underwater production system, infusion pipeline-riser system, water fixed / floating structural facilities and upper processing systems.

[0003] In the early and at the end of the development of oil and gas fields, when the output of oil and gas is low, the strong stream flow is often generated in the transmission pipeline-riser system.The strong segmentation flow refers to: the length of the liquid plug is at least 1 times the stream of the riser length. It has a periodic period. Each cycle includes 4 stages: liquid pluggingBroken / liquid fa...
