【 摘 要 】

The effect of increasing cement prices and expensive additive will have an impact on the cost of cementing of oil and gas wells. So, the need for a strategy undertaken in order to minimize the cost of cementing other than that a good cement strength with additive alternative materials is necessary. Strategies are carried out by using materials that are economical and environmentally friendly in which the material is organic waste materials that have elements of silica and are pozzolanic. As for organic ingredients that are pozzolanic is bagasse ash. In addition, to reduce the level of cement pores, it is necessary to add additional additives by using nanosilica. Testing of the physical properties of cement conducted in laboratory research is by testing strength on cement with additives of bagasse ash added nanosilica into drilling cement suspension with temperature conditioning research 120°F pressure 14.7 psi and 24 hours in the water bath. The results of the research on several scenarios of the concentration of the addition of bagasse ash showed that the optimal compressive strength value obtained was 991.83 psi and the optimal shear bond strength obtained was 97,49 psi at the concentration of ash bagasse in 5% and nanosilica 0,019% in drilling cement.
