Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described:

[0017] Depend on figure 2 combine image 3 Shown: a multi-stage gas-liquid two-phase separation device, including a cylinder 13, a mixed liquid inlet pipe 11 and a gas collecting pipe 19, the cylinder 13 is composed of a cylinder and a bottom, wherein the cylinder is cylindrical or elliptical Cylindrical, the bottom adopts an eccentric funnel structure, and the upper mouth of the funnel is a slanted mouth with a high left side and a low right side. The outlet of the cylinder is also located on the right side of the center line of the cylinder 13, so the left side of the bottom of the cylinder 13 The inclined wall a is longer than the right inclined wall b; the mixed liquid inlet pipe 11 extends into the cylinder from the top of the cylinder body 13, and the outlet of the mixed liquid inlet pipe 11 is provided with a primary separation screen 12, and the primary separati...

Abstract

The invention discloses a multilevel gas-liquid two-phase separation device, which solves the problems in the existing separation device that gas-liquid separation is not thorough and carbon dioxide cannot be collected completely. Three-level separation technology is adopted by the separation device, wherein a first-level separation sieve adopts a nozzle-type structure for sieving, and a second-level separation sieve and a third-level separation sieve both adopt an eccentric funnel-type structure, so that a gas-liquid mixture can be separated as long as possible on an area as large as possible, the gas-liquid mixture is fully separated, a good separation effect is achieved, meanwhile, a three-level collection mode is adopted, gas after each level of separation is collected, and separated gas is completely collected, so that guarantee is provided for carbon dioxide drive physical simulation experiment.

Description

technical field [0001] The invention relates to a gas-liquid separation device for a physical simulation experiment of carbon dioxide flooding. Background technique [0002] In the physical simulation experiment of carbon dioxide flooding, gas-liquid separation and accurate metering are the key steps to determine the quantification of oil displacement effect, so whether the gas-liquid separation and gas collection are complete is particularly important. [0003] The original gas-liquid separation device is attached figure 1 As shown, it is composed of a mixed liquid inlet pipe 1, a gas-liquid separator cylinder 2, and a gas collecting pipe 3. The mixed liquid inlet pipe 1 and the gas collecting pipe 3 are located at the upper part of the cylinder, and the main body of the gas-liquid separator cylinder 2 It is a cylindrical structure with an eccentric funnel structure at the bottom for liquid collection; the gas-liquid mixture generated by the oil displacement model flows in...
