Integrated compound overweight injection system and working method thereof

Abstract

The invention discloses an integrated compound overweight injection system and a working method thereof and belongs to the technical field of petrochemical equipment. The system comprises a loading mechanism, a compound overweight mechanism, a driving mechanism, a pressurizing pump and a mixer arranged on a rack. The loading mechanism mixes water with a main agent and an auxiliary agent of an intelligent energy-gathering oil-displacing agent preliminarily; an outlet of the loading mechanism communicates to an input port of the compound overweight mechanism through a pipeline; the compound overweight mechanism carries out stirring, mixing, dissolving and overweight curing on the mixed solution which is preliminarily mixed to form mother liquor; the mother liquor is input to an inlet of thepressurizing pump through a pipeline by means of an output port of the compound overweight mechanism; the pressurizing pump injects the pressurized mother liquor into the mixer; the mixer mixes the mother liquor with diluted high pressure water and injects a mixture into an oil-water well; and the compound overweight mechanism and a power shaft of the pressurizing pump are driven by a driving mechanism. According to the technical scheme, the occupied area and space of the equipment are reduced greatly, the dispersing, dissolving and curing times of preparing the intelligent energy-gathering oil-displacing agent are greatly shortened, and the injection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment, in particular to an integrated composite overweight injection system and a working method thereof. Background technique [0002] The original onshore tertiary oil recovery, smart energy flooding and other uses of injection preparation, dissolution and aging technology, the process is too long and the equipment occupies a large area, such as daily preparation of 50m 3 High-concentration mother liquor covers an area of ​​200m 2 above, hundreds of m 3 The preparation of / d mother liquor requires a larger area. The process is long, there are a lot of equipment, there are many sets of installed machines, the power consumption is high, and the management and maintenance are difficult. There is a problem of taking up a large space and a large site. [0003] In the prior art, see attached figure 1 1. Preparation of smart oil-displacing agent solution: pass the smart-poly oil-displaci...

AI Technical Summary

Problems solved by technology

Usually there is a problem that multi-well production operations cannot be carried out at the same time, but only a single implementation; production requires technical measures and equipment to occupy an area of ​​no more than 30m 3 ; The injection volume is large, most of the water injection wells in offshore oilfields are horizontal wells, the injection volume of a single well is large, hundreds to thousands of cubic meters per day, and the injection equipment process will occupy a larger area; the transportation, installation and maintenance of materials and equipment are difficult and the labor costs are high Poor environment and environment; ocean typhoon environment corrosion, high cost of construction and maintenance of supporting facilities, etc.

[0007] Therefore, the oilfield injection system of the prior art has a long flow process, many equipments, many sets of installed machines, a large floor area and a large space volume, and a long maturation time, low efficiency, high power consumption, and difficult management and maintenance.

It cannot be applied to offshore oilfield platforms with small area and limited installation space or other oil production occasions with limited installation space
