HLB product is a water-base drilling fluid with extreme pressure lubricant, is composed of a variety of special surfactant, compared with similar products, it can form a layer on the surface of drilling, drilling tools, and other tools of solid adsorption film, can greatly reduce the tool wear i the drilling process and fatigue, prolongs the service life of drilling, bearings and other tools; Prevent the occurrence of adhesion stuck accident of downhole drilling tools, shorten the trip time and improve the drilling speed; The fluorescence of the product is lower than 3.0, the biotoxicity meets the requirements of environmental protection, and it is easy to biodegrade. Temperature resistance up to 200℃, salt resistance up to saturation, calcium resistance and no bubble; It has no adverse effect on fluid rheology properties and fluid loss, and is an ideal additive for reducing friction and increasing velocity in vertical wells, exploration wells, highly deviated wells and horizontal wells.
