High-temperature oil well cement:
As oilfields go into middle and later development period, shallow layer resources dramatically reduce or conventional oil or gas resource output reduces day by day. Consequently, people turn their eyes to deep wells, ultra-deep wells and heavy oil resource in oil and gas development. Whether for deep wells, ultra-deep wells or heavy oil thermal recovery wells, high temperature is the key problem to be addressed in designing oil well cement.
In order to address the problems of compressive strength declination and permeability increase of oil well cement sheath around the wellhole at high temperature and ensure stability and homogeneity of set cement, our company developed high-temperature oil well cement applicable to heavy oil thermal recovery well cementing. With stable high temperature resistance, it is applicable to the temperature range of 110-600℃.
