New composition of chemicals and heavy drilling fluids for drilling oil and gas wells

The article shows the importance of obtaining new composition heavy drilling fluids based on composite chemical reagents from local raw materials and industrial wastes for oil gas wells. In process building wells to maintain stability walls, prevent flow salts, penetration formation into well, it becomes necessary increase density fluid, which can be accomplished by introducing components with increased density. For stabilization fluid were investigated recommended compositions powder water soluble gossypol resin carboxymetylcellylose sodium other minerals. Stabilization indexes their determination in have been investigated. result research implemented abnormally high reservoir pressure.
