【 摘 要 】

Cement drilling is one of the factors that influence the success in drilling. Cementing is the process of pushing the cement slurry into the casing and up to the annulus of the borehole casing, then the cement slurry is allowed to harden. The main purpose of this study is to determine the effect of add natural additives which include bagasse, ash straw and sawdust wood albasia on drilling cement. Natural additives have advantages over chemical additives such as cheap, easy to obtain and more friendly to the environment. The natural material serves as extender, which lowers the density of the cement also serves to increase the yield slurry, reducing free water in the cement suspension resulting in strong compressive strength of cement. The first sample is the basic sample, the second sample is the first sample of 0.3% additive of bagasse, the third sample is the first sample of 0.3% additive of ash straw, the fourth sample is the first sample of 0.3% additive of sawdust wood albasia. The results of the research showed that the composition of cement slurry with ash straw additive has the best compressive strength.
