用于石油生产的微乳液粘度降低剂

The chemical mixing and preparation device is used for uniform blending, dilution and proportioning of viscosity reducers. The high-pressure injection pump set pumps the microemulsified viscosity reducer into the wellbore and formation. The wellhead injection and pipeline system realizes safe chemical delivery, pressure control and process switching.

Microemulsion stabilization technology forms a uniform and stable microemulsion system with good dispersion, high temperature resistance and high salt tolerance, adapting to complex reservoir environments. Resin & asphaltene cracking viscosity reduction technology destroys the macromolecular structure of heavy oil, greatly reduces crude oil viscosity and improves fluidity. Low interfacial tension flooding technology reduces oil-water interfacial tension and improves oil washing efficiency and crude oil recovery. High-efficiency penetration and emulsification technology quickly penetrates crude oil to form low-viscosity emulsion for easy lifting and transportation.

Types and Characteristics of Equipment

Type

Oilfield Chemicals Belong to the category of chemical additives for oil production. They are functional products designed specifically for oilfield development, meeting the viscosity reduction requirements of crude oil under various reservoir conditions.

Microemulsified Viscosity Reducer Different from conventional viscosity reducers, it takes a microemulsion system as the core and integrates multiple functions including viscosity reduction, emulsification and dispersion. It is suitable for high-viscosity and high-wax crude oil.

Oil Production Stimulation Additives Their core functions are to reduce crude oil viscosity, improve fluidity, lower pipeline transportation resistance and enhance oil recovery efficiency. They are classified as chemical products for oilfield stimulation and efficiency improvement.

Features

A high-efficiency nano-emulsion system for the exploitation and gathering transportation of heavy oil and super-heavy oil. Its core features include high-efficiency viscosity reduction at room temperature, strong permeability, high stability, low formation damage and easy demulsification, showing significant advantages over conventional emulsions and oil-soluble viscosity reducers.

Basic Principles and System Composition

Basic Working Principle

This product adopts a microemulsified viscosity reduction mechanism and forms a uniform and stable microemulsion system through surfactants.

It rapidly penetrates into high-viscosity crude oil, destroys the resin and asphaltene structures, and reduces intermolecular forces.

It forms a low-viscosity emulsion with crude oil and water, greatly reducing the apparent viscosity of crude oil.

It lowers oil-rock and oil-pipe interfacial tension, improves crude oil fluidity, reduces flow resistance, and enables smooth lifting and transportation.

Overall System Composition

The microemulsion main component forms a stable microemulsion system, ensuring uniform dispersion and stable performance. High-efficiency viscosity-reducing active components destroy the resin and asphaltene structures of crude oil, lowering viscosity and interfacial tension. Surfactants improve the oil-water interface state and enhance emulsification, dispersion and oil displacement effects. Stabilizers and salt-resistant components improve stability under high-temperature and high-salinity formation conditions. Cosolvents and penetrants increase penetration speed into crude oil and boost viscosity reduction efficiency.

Basic Principles and System Composition

Chemical Preparation Stir the microemulsified viscosity reducer with water thoroughly at the designed concentration to prepare a uniform working fluid.

Pumping Operation Inject the working fluid into the wellbore and target formation by high-pressure injection pump.

Shut-In Reaction Shut in the well to allow sufficient penetration, emulsification and viscosity reduction of crude oil.

Flowback & Production Open the well to flow back residual liquid and restore well production. Crude oil fluidity is significantly improved to achieve normal recovery.
