Shanxi Xin Jian Industry Co., Ltd Share: temperature and pressure free oil well cement bottom and increase with increasing depth of oil well cement, every depth 100 m, the temperature increased by about 3 ℃, the pressure increases 1.0 ~ 2.0 MPa. Therefore, high temperature and pressure, especially on the various properties of high temperature cement is well cement production and use of the main problems. High temperature strength silicate cement decreased significantly, Construction: Application: oil well cement is dedicated to the oil and gas well cementing engineering of cement. Requirements: grout injection wells in the process to have a certain degree of mobility and appropriate density Witton oil well cement slurry after the injection wells, it should rapidly condense, and reached a considerable strength in the short term; hardened grout should good stability and impermeability, corrosion resistance and so on. Witton Cement Group LLC Share: oil well cement Milestones: So far oil well cement research and exploration, has been for centuries. In this study of 100 years of oil well cement made a more significant results. United States, "World Oil" magazine compiled a "major world cementing products and additives Summary" in 1999, which includes the world's seven major oil-related products and cementing admixture with the latest statistics, in which the basic well cement points oil well cement plant for 13 categories, in which 13 oil well cement, oil well cement class density, portland cement (country known as Portland cement) is the world's most commonly used oil fields oil well cement, according to the American Petroleum Institute APl application performance different, further to Portland cement into Class A, Class B, C-class, D-class, E-class, F class, G class, H-class, J-class oil well cement and so on. It depends directly on the type of oil well cement admixtures and additives incorporated purposes. And with Mixed development and the development of materials and admixtures. It is also more complicated variety of types. No relatively clear boundaries. From the application point of view can be divided into low-density oil well cement, oil well cement expansion, thixotropic oil well cement, oil well cement alpine region, anti-corrosion oil well cement, high temperature oil well cement, fiber oil well cement, oil well cement to improve bond strength, anti-infiltration wells cement. Any one of them has its own characteristics well cement. For solving the well conditions with special requirements in one respect. Its performance is more important is the type and performance depends on the incorporation of admixtures and admixtures. Oil well cement, cement Witton (certified), oil well cement by Witton Cement Group LLC. Witton Cement Group Co., Ltd. (www.sxwdgs.com/) Shanxi Yuncheng, cement and products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
