In-Situ Chemical Injection

In-Situ Chemical Injection

Micro-Fracturing Direct Injection Technology

Micro-fracturing direct injection technology utilizes the injection module of EP series drilling rigs to create fracture networks in unconsolidated formations through hydraulic fracturing. This process enables the precise injection of remediation agents to achieve rapid pollutant degradation or effective containment in target areas.

• Enhanced Formation Permeability Modifies subsurface permeability to address challenges in low-permeability formations where traditional injection wells often fail.

• Precision Injection Prevents secondary contamination by ensuring accurate agent delivery, avoiding dispersion during injection.

• Efficient Remediation Shortens treatment cycles while improving remediation outcomes through optimized fracture networks and agent distribution.

• Environmental remediation of contaminated sites with unconsolidated formations (e.g., soil, sediment).

• In-situ treatment of pollutants requiring controlled hydraulic fracturing and targeted agent injection.

• Cost-Effective: Reduces operational time and material waste compared to conventional drilling methods.

• Adaptability: Compatible with EP series rig systems for seamless integration into existing workflows.

Horizontal injection technology involves drilling and installing horizontal wells or boreholes in groundwater or soil. Target substances are injected underground through these channels. By leveraging the horizontal distribution characteristics of the wells/boreholes, this method ensures even distribution of injected substances over large areas, achieving purposes such as remediation, treatment, or other objectives.

• Efficient Substance Distribution Utilizes horizontal wells/boreholes to achieve uniform coverage in groundwater or soil.

• Targeted Application Enables precise injection for environmental remediation or pollutant management.

• Groundwater Treatment: Removes contaminants through controlled injection.

• Environmental Restoration: Restores ecosystems by distributing remediation agents.

• Pollutant Management: Injects/extracts pollutants for in-situ treatment or containment.

• Broad Applicability: Suitable for unconsolidated formations and complex subsurface environments.

• Cost-Effective: Reduces material waste and operational complexity compared to vertical methods.

Airbag Isolation Injection Technology

Airbag isolation injection technology is a depth-controlled injection method that utilizes airbag isolation devices to precisely deliver underground water and soil treatments.

By inserting airbag isolation devices into injection wells and inflating them, sealed isolation zones are formed to prevent the dispersion of injected agents. Within these isolated zones, targeted agents are delivered through injection pipelines to groundwater or soil for remediation, treatment, or monitoring purposes.
