MicroPOR Casing Sealing Repair Technology

n  Technical Introduction

    MicroPOR casing sealing repair technology offers a drilling-free chemical plugging solution utilizing dispersible, adjustable particle size, and curable gel materials. These materials, with varying particle size gradations, enter the leakage channel under pressure, where they gather and bridge, forming a solidified plug at the point of leakage. This technology ensures fluidity within the wellbore, facilitating direct cleaning and discharge.

n  Technical Features

    ( 1 ) Demonstrates excellent stability, maintaining long-term filling without settling.

    ( 2 ) Avoids mass solidification, mitigating potential wellbore safety concerns.

    ( 3 ) Capable of repairing the well section without pinpointing the exact leakage location.

    ( 4 ) Simplifies wellbore cleaning, requiring no drilling plug, and causes no corrosion.

    ( 5 ) Post-plugging, it exhibits resistance to acid and alkali corrosion, with a compressive capacity of 115MPa.

n  Application

    MicroPOR has been successfully applied in numerous oilfields, including those of CNOOC and Sinopec, with a 100% success rate in repairing casing thread leakage. Effective across a range of leakage rates (2L/min to 10L/min) and pressures (70MPa to 115MPa), showcasing its reliable plugging performance.
