Crude oil mixed-transferring integrated device and method

Abstract

The invention relates to a skid-mounted integrated device of medium and small sized mixed-transferring stations in a low permeability oil field, in particular to a crude oil mixed-transferring integrated device and a method of heating, separating, buffering, pressurizing and out-transferring processes during the oil field production and building project, which can realize at least four production processes. Pressurizers in the production processes 1 and 2 can realize mutual reservation. The production processes 1 and 3 are suitable to the condition that casing gas is used as fuel of a heating device; the processes of 1 to 3 are suitable to the condition of crude oil without being heated, the crude oil can not be performed by the heating procedure, the separating procedure, the buffering procedure and the like under the condition; the process 4 is also suitable to the condition that the crude oil can meet the out-transferring condition without being heated, and the crude oil can not be heated under the condition. The invention can meet the production requirement by adopting any one of processes, and is more suitable to a multifunctional integrated device of heating, buffering, separating, pressurizing, metering and the like of the crude oil.

Description

technical field [0001] The invention relates to a skid-mounted integrated device for small and medium-sized gathering and transportation stations in low-permeability oilfields, in particular to a crude oil mixed transportation integrated device and method for heating, separating, buffering, pressurizing and external transportation processes in oilfield production and construction projects. Background technique [0002] The development of ultra-low permeability reserves in domestic oilfields is advancing rapidly, but the equipment and processes used in the pressurization (transfer) stations of small and medium-sized gathering and transportation stations in existing low-permeability oilfields have the following problems: a large number of equipment, long production and construction cycles; complex processes, Inconvenient operation and maintenance; larger floor space, higher investment, etc. Contents of the invention [0003] The purpose of the present invention is to provide...
