Product Introduction

Based on a single-phase microemulsion spontaneously formed by limonene, surfactant, complexing agent, cosolvent and water in a certain proportion, the acid system is formed through organic acid oxidation, nucleophilic addition reaction and electron cloud rearrangement among molecules.

It integrates the dual functions of microemulsion and organic acid, dissolves and etches to enhance permeability, and improves oil washing efficiency.

As a new type of organic acid, it fills the gap in the industry.

Features

Nano‑scale acid‑in‑oil (W/O) slow‑release acidizing system. It features retarded reaction, low corrosion, deep penetration, strong blockage removal and high temperature stability, specially designed for low‑permeability, tight, high‑temperature and high‑calcium oil reservoirs.

Microemulsified Lactic Acid for Oil Production

Microemulsified lactic acid for plug removal and enhanced oil recovery.

Microemulsified Lactic Acid for Oil Production

Slow-release acid fluid with high temperature resistance and good compatibility.

Basic Principles and System Composition

Basic Working Principle

Deep Retarded Acidification

Slowly releases acid to avoid excessive dissolution near the wellbore, achieves deep plug removal and deep-penetration fracture creation in the reservoir, and extends the acidizing distance.

Dissolution of Plugging Substances

Efficiently dissolves calcium scale, mud contamination and inorganic deposits, unclogs seepage channels and restores formation permeability.

Reduction of Tubing String Corrosion

Forms a protective film in the wellbore, significantly slowing acid corrosion on tubing, casing and downhole tools.

Oil Washing & Wettability Alteration

Reduces interfacial tension, strips oil film from rocks, improves wettability and enhances crude oil flow and recovery efficiency.

High Temperature & High Salinity Resistance

Stable without demulsification in high-temperature, high-salinity formations, adapting to complex oil and gas well conditions.

Easy Flowback & Low Formation Damage

Rapid demulsification and flowback after treatment, reducing secondary precipitation and formation damage to protect long-term productivity.

Single-Well Production Improvement

Reduces flow resistance through combined plug removal, permeability enhancement and oil washing, improving oil well production and water well injectivity.

Overall System Composition

Lactic Acid Base Fluid

The main lactic acid component provides an organic acid source to achieve retarded acidizing and blockage removal.

Microemulsion System

Reduces surface tension, improves formation permeability and oil washing efficiency.

Surfactant Component

Stabilizes the emulsion and enhances emulsification, dispersion and oil displacement performance.

Corrosion Inhibitor

Protects tubing, casing and equipment from acid corrosion.

Stabilizer & Compatibility Agent

Ensures system stability under high-temperature and high-salinity formation conditions.

Slow-release Additives

Enable gradual acid release, extending the effective distance and duration of action.

Basic Principles and System Composition

Operating Procedure

Prepare and dilute microemulsified lactic acid solution according to formation conditions. Pump the prepared acid fluid into the wellbore and target formation by injection pump. Shut in the well to ensure sufficient reaction for plug removal and oil displacement. Flow back the reacted fluid and clean the wellbore to restore oil production capacity.
