Abstract:The factors that influence the piping occurring in embankment are uncertain and random, and in the process of piping they turn out to be nonlinear behavior. RBF neural network theory was used to establish a new model in order to predict the piping of embankment. This paper discussed the establishment of predicting model and process of application in detail. Comparing with BP neural network, the application in 23 cases of embankment piping shows that RBF network be more precise, more quickly and faster.

Abstract:Solid control on drilling fluid is an essential technique for under-balanced drilling. Preparation, control and maintenance for emulsified drilling fluid will directly affect the forecast on oil and gas. With the drilling experience in SN308, each performance index of emulsified diesel oil drilling fluid was determined by design of negative pressure value of the formation and calculation on the fluid density and water pressure. The method of usage and maintenance of the fluid were suggested and applied successfully in the construction.
