1. Product Description
DOC-BT4 is a reinforcing material commonly used in low density cement slurry system. It can effectively guarantee the strength development of cement paste at low temperature, and it is an oil well cement admixture with hydration activity based on the theory of particle size distribution. It can be used together with all grades of oil well cement defined by GB10238 or APISpec10A. After matching the lightening agent, a high-performance and low density cement slurry with a density of 1.35 to 1.75g/cm3 will be made out, which is comparable with normal density cement slurry. The material has good compatibility with various oil well cement admixtures.
2. Usage
Temperature: 20~180 ℃ (BHCT)
Recommended amount: 20-30% of cement
High strength low density cement slurry is suitable for low pressure and leakage wells, long sealing wells, horizontal wells, thermal recovery wells and general wells of cementing operation.
