Shan Xi Wei Dayton Cement Group Co., Ltd. Share: oil well cement dedicated to oil, gas well cementing engineering, also known as plugging cement. Its main use is to master the casing and the surrounding rock cemented cementing, packer within the formation of oil, gas, water layer, to prevent cross-talk with each other, so that the flow of oil from the well to form a good ground and cut off the oil flow channel. Basic requirements for oil well cement: water slurry have a certain mobility and a suitable density in the course of injection wells; slurry after injection wells, should quickly condense and achieve comparable strength in the short term; hardened grout should have good stability and impermeability, corrosion resistance. Witton Cement Group Co., Ltd. Share: low oil well cement early strength agent Research and Evaluation Summary: low early strength cement slurry is designed to meet the low temperature conditions to produce a kind of cementing grout, aiming at Daqing oilfield drilling during winter When surface casing cementing low formation temperature well cement composition, cement strength development is slow, long time and so on WOC, developed a new type of low-temperature coagulant early strength agent QZ-1, the early strength agent is active silica fume, solid alcohol amines and anionic polymer compound obtained by a certain percentage, and can greatly accelerate the rate of hydration of cement and promote the formation of the early strength cement; the early strength agent does not contain chlorine ions, can overcome the traditional chlorine casing corrosion problems caused by the early strength agent, at the same time, the activity of silica fume cement wells containing the early strength agent, and can react with cement, so that a slight expansion of the volume of cement; solid alcohol amines can cement particles and water molecules hydrogen bonds and van der combination of gravitational well cement standards, cement particles are adsorbed to deepen the depth of cement hydration reaction; there are a lot of adsorption groups (hydroxyl, amide) and hydration group (carboxyl) on the anionic polymer chains can be adsorbed on cement particles, increasing the viscosity of the cement slurry. QZ-1 early strength cement slurry affect performance, including compressive strength of the experimental study analysis. Oil well cement standards, Witton cement (certified), oil well cement by Witton Cement Group, LLC. Witton Cement Group Co., Ltd. (www.sxwdgs.com/) Shanxi Yuncheng, cement and products of leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
