Expending agent TE91

 Description

TE91 oil well cement expansive agent is a mixture of calcium oxide and its salts, magnesium oxide and its salts. cements  with this agent have stable expansion effect. The high temperature expansion agent has no sensitivity, the expansion effect increases linearly with the increase of the amount, the shape of thickening curve is good, the rheological property is good, and it is easy to ensure the safety of operation. It can be used in cement slurries with various water quality and has good compatibility with other oil well cement admixtures. High temperature oil well cement expansion agent has a wide range of applications, the formula and performance of cement slurry are easy to adjust, and the comprehensive performance of cement slurry is good, which is conducive to improving the cement bond quality.
