Micronized barite is a kind of weighting agent material processed and manufactured with high-quality barite as raw material and special process technology. lt is widely used in ultra-high density drilling and completion fluid. Combined with conventional barite, it can improve the rheology ofhigh-density drilling fluid, reduce the precipitation and consumption ofbarite, and reduce the cost of drilling and completion fluid.

Fn-0-C800 is a nano multifunctional drilling fluid additive, which is applicable to water-based, oil-based and synthetic based drilling fluid. lts main functions include: effectively blocking formation micro fractures orpores, reducing the invasion of drilling fluid filtrate into the formation, weakening the destructive effect of hydraulic wedging effect on wellbore shale and improve wellbore stability; Reduce the high temperature and high pressure filtration of drilling fluid; Reduce friction torque; Increase the fracture pressure of sandstone and shale.

High temperature and salt resistant filtrate reducer ATJQ-4 is a white powder polymer product, which is suitable for all kinds of fresh water, salt water and seawater drilling fluid systems. lts temperature resistance is up to 210 'C. ATJQ-4 can be well used in combination with other water-based drilling fluid treatment agents often used in the industry. Practice has proved that, It is a high-quality high-temperature and high-pressure filtration control chemical agent for water-based drilling and completion fluid system.

The primary emulsifier for oil-base mud MOEMUL-S is a low molecular polymer with a variety of surface active groups synthesized by molecular structure design.lt can be used in conjunction with MOCOAT-S CO emulsifier in the field to form an adsorption film with a certain strength at the oil-water interface, reduce the tension at the oil-water interface and increase the viscosity of the external phase. In this way, the dispersion phase droplets are prevented from coalescence and becoming larger, and the stability of oil-base drilling fluid is significantly improved. The drilling fluid still has good performance at high temperature and high density. MOEMUL-S and its auxiliary emulsifier MOcOAT-S have stable rheological properties and high temperature and pressure filtration performance before and after rolling at high temperature, and strong resistance to various pollutants. lt is an excellent main emulsifier for oil-base drilling fluid system.

The fatty acid derivative MOCOAT-S is used to enhance the stability of oil-base drilling fluids. When used in combination with the primary emulsifier MOEMUL-S, it can significantly improve the stability of oil-base drilling fluids in a wide range of oil-water ratio (40/60 ~ 10/90), and has good stability to the oil-base drilling fluids system. It has good emulsification property with the main emulsifier and other treating.

MOTEX oil-base mud filtrate loss reducer is a kind of natural asphalt modified product. The product has good temperature resistance and filtration loss reduction effect, and the filtration performance of the system can be significantly improved in a certain temperature range. It is a kind of high quality and low price filter loss agent for oil-based drilling fluid system. It also has good compatibility with other treating agents in the system.

Oil based drilling fluid wetting agent ATWET is a polymer product synthesized with oleic acid as the main raw material. It is mainly used to change barite and other weighting materials or the surface of drilling cuttings from hydrophilicity to lipophilicity in oil-based drilling and completion fluid, increase the system stability of oil-based drilling and completion fluid, and reduce the viscosity, improve the rheology of the system.

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.

The environment-friendly starch fluid loss additive is a kind of fluid lossadditive product synthesized with starch as the main raw material. lt ismainly used for the control of filtration loss of water-based mud. This product can be used not only in fresh water drilling fluid, but also in seawater and saturated salt water drilling fluid, with good salt resistance.Compared with common starch filtration reducer, this product can effectively solve the problems of product failure and mud performance deterioration caused by fermentation and odor during use.
