First, the use of products
By drilling mud with my company to jointly develop a green environmental protection chemical reagent of chitosan inhibitor KD-03 it is made of gum modified through high temperature reaction and its main effective components for the plant mixed poly glycoside and its derivatives, than multi glycoside has more function and higher temperature resistance and salt limit. The main mechanism of action: its strong inhibition effectively to avoid or reduce the clay mineral hydration swelling and dispersion of reservoir damage caused by molecular aggregation; bring into low membrane filtration and good wall building of effective control of the reservoir damage caused by solid and filtrate; low surface tension between water and rock mineral particles and low interfacial tension was effectively reduced by leachate retention effect caused by reservoir damage, and lubricating effect on mud cake surface; ring hydroxyl molecular structure unit has the structure effect effectively inhibit gas hydrate and the performance of the frost resistance of certain large molecules; the linear polymer, has certain viscosity. As the additive of the drilling fluid and completion fluid, it has good inhibition, lubricity, with oil base mud properties of novel inhibition water-based pseudo oil-based drilling fluid, can better protecting oil and gas reservoirs, especially for low permeability, poor physical property, pore throat fine, sensitive to water, oil and gas may cause damage to reservoir formation, at the same time, there are no fluorescence, non-toxic, biodegradable properties is an environment can receive the new modified biological products.

Three, the use of methods
In the mud of the recommended amount of 2%-5%, the site according to the design and the actual situation to adjust.
Four, storage and transportation
1 store in a cool, dry, ventilated place, prevent direct sunlight, away from the fire source.
2 transport and handling should be handled gently and prevent violent collision, extrusion, inversion.
Five, matters needing attention
In the use process, the staff shall wear labor protection supplies, to prevent products splashed into the eyes or contact to the skin, once the occurrence of the above phenomenon, immediately wash with plenty of water, in serious cases, timely medical treatment. Sprinkle on the ground should be as far as possible, for a small number of products with soil landfill, you can also use a large amount of water to wash, wash water into the waste water system.
