Product Introduction

Reducing the water lock effect is an important measure to protect natural gas reservoirs. Due to the fine pore throats and high capillary pressure in low-permeability gas reservoirs, there is greater fluid confinement and water locking effect damage. This requires drilling fluid, completion fluid, and other filtrate that invade the pore throats in advance to have lower surface tension, lower interfacial tension, and higher contact angle. The main components of waterproof lock agent are fluorocarbon surfactants and modified surfactants. This product has low surface tension and interfacial tension. Mainly used in natural gas well water lock removal process, to remove water lock damage in the production layer, restore gas well permeability, improve gas production capacity, extend gas well production cycle, and enhance recovery rate. Good compatibility with formation water, tap water, and fracturing fluid, and simple on-site construction.
