Shan Xi Wei Dayton Cement Group Co., Ltd. Share: B and B-class oil well cement concrete Class B oil well cement apply the same depth with a Class A cement oil well cement, but it also has anti-sulfate performance. Class B oil well cement into anti-sulfate type and high resistance to sulphate-two, for from the ground to the depth of 1830m, Class B cement and ASTM standards similar type Ⅱ. Below with the Class B sulphate resisting cement wells example. Pipe Co., Ltd. Shanxi Xin Jian Share: oil well cement each level range as follows: A grade: Use oil well cement prices in the absence of specific performance requirements, applicable from the floor to a depth of 1 830 m cementing. Just ordinary type. Class B: suitable for downhole conditions require the use of high early strength cement Witton when applied to 1 830 m from the floor to the depth of the injection of cement. Into anti-sulfate type and high resistance to sulphate type two types. Class C: suitable for downhole conditions require the use of high early strength for 1 830 m from the floor to the depth of the injection of cement. Divided into common type, anti-sulfate type and high resistance to sulphate three types. Class D: suitable for medium temperature and pressure downhole conditions used into anti-sulphate and sulphate type two types of high resistance. E Class: suitable for use in high temperature and pressure conditions for oil well cement standards were divided into high resistance to anti-sulphate and sulphate type two types. Class F: When suitable for ultra-high temperature and pressure conditions were divided into high resistance to anti-sulphate and sulphate type. Class G, H level: a basic well cement, into the anti-sulfate type and high resistance to sulphate two types. J Class: Suitable for 3 660 ~ 4 880 m depth under ultra-high temperature and pressure conditions of the cementing. The physical properties of oil well cement requirements include: water-cement ratio, cement surface area, initial consistency within 15 ~ 30 min, thickening time at a specific temperature and pressure as well as compressive strength at a given temperature, pressure and curing period of Yuncheng oil well cement cement plant _ _ Witton cement provided by Witton Cement Group Co., Ltd.
