Cement compositions and methods
专利汇可以提供Cement compositions and methods专利检索，专利查询，专利分析的服务。并且A ''''basic'''' cement of enhanced properties particularly useful in the cementing of wells, methods of making it, and methods of cementing geologic formations traversed by well bores are disclosed. The cement composition comprises a hydraulic cement intimately pretreated with a small amount of water and aged or cured for at least 30 minutes. The preferred amount of water is from about 0.5 percent to about 1.0 percent by weight of the cement; although higher and lesser amounts of water may be used. As much as about 5% water is satisfactory if the aged cement is used within a relatively short period of time, but there should not be enough water added to provide substantial lumping or hydration of the cement. The ''''basic'''' cement composition when pretreated with water has good compatibility with various additives, retarders and the like, good viscosity and strength, increased thickening times, and a reduced amount of mix water may be used thereby increasing the weight of the cement slurry. The method of preparing the cement composition includes pretreating a hydraulic cement by intimately mixing, preferably with a fine spray, a small amount of water, as indicated in the amounts above, and aging or curing for at least 30 minutes before use. The water can also be incorporated in the cement by adding the small amount of water to an inert carrier, such as Diatomaceous silica then intimately mixing the carrier with the cement and aging or curing for at least 30 minutes. The method includes adding various additives as desired, such as retarders and the like. The method of performing cementing operations in geologic formations comprises placing the cement composition in such formations for bonding and plugging purposes. There are a number of examples disclosed giving the cement composition, and methods of making and using it.，下面是Cement compositions and methods专利的具体信息内容。
