Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Abstract: A distributed system, such as a distributed storage system in a virtualized computing environment and having storage nodes arranged in a cluster, is provided with capability by a management server to detect mutually exclusive features. If a feature being requested for installation is detected as being a mutually exclusive feature by using a first table, the management server searches for the feature in second table. If the feature is located in the second table and if the feature meets a condition for interoperability specified by the second table, then the management server proceeds with serving the request by installing the feature in the distributed storage system. Else, the management server rejects the request.
