High-temperature gas-carrying super-heavy oil slug flow trapping and treating integrated device

Abstract

The invention relates to the technical field of slug flow trapping devices and particularly relates to a high-temperature gas-carrying super-heavy oil slug flow trapping and treating integrated device. The high-temperature gas-carrying super-heavy oil slug flow trapping and treating integrated device comprises a steam treater, a prying seat and a slug flow trap, wherein the steam treater is fixedly arranged on the prying seat through a supporting seat; the lower part of the left end of the steam treater is provided with a liquid inlet end; and the middle part of the right end of the steam treater is provided with a liquid outlet end on which a liquid outlet pipe is fixedly arranged. The high-temperature gas-carrying super-heavy oil slug flow trapping and treating integrated device is reasonable and compact in structure and convenient to use; due to the coordinated application of the steam treater, a gas and liquid mixed conveying pipe, a liquid collecting pipe, a horizontal steam collecting pipe and a vertical branch pipe, the two-phase pre-separation of gas and liquid is realized, and a liquid slug generated by oil and gas mixing is effectively trapped; the apertures of an exhaust valve and a drain valve are regulated through a pressure sensor and a liquid level sensor, so that impact to the next-grade treating equipment is avoided; and the high-temperature gas-carrying super-heavy oil slug flow trapping and treating integrated device has the characteristics of good steam-liquid separation effect, operation stability and small floor area and is convenient to operate and capable of increasing the steam-liquid separation efficiency.

Description

technical field [0001] The invention relates to the technical field of slug flow capture devices, and is an integrated device for slug flow capture and treatment of high-temperature steam-carrying ultra-heavy oil. Background technique [0002] Steam-assisted gravity drainage (SAGD) is a cutting-edge technology for developing super-heavy oil at home and abroad. Its principle is to inject high-quality steam into the steam injection well to form a steam cavity in the oil layer, and exchange and transfer heat with the oil layer. , so that the viscosity of crude oil is reduced, and the heated crude oil and steam condensate flow into horizontal production wells for production by gravity. SAGD production fluid has high temperature (temperature ranges from 160°C to 180°C, the highest temperature can reach 220°C), large steam carrying capacity (steam carrying amount ranges from 20% to 50%, and the maximum can reach 80%), and serious sand carryover. The treatment method mainly realiz...

Problems solved by technology

[0004] The present invention provides an integrated device for slug flow capture and treatment of high-temperature steam-carrying ultra-heavy oil, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem of The unstable operation of the existing ultra-heavy oil steam processor leads to the separation of more liquid entrained in the steam, and at the same time, it has a serious impact on the downstream processing system. The high content of silt and sand in the SAGD production and the small particle size of the sand carry lead to a low operation rate of the equipment question
