The sedimentary characteristics of Feixian Guan Formation in Lower Trassic System, Beipei area，have been discussed in this paper. It is believed that the carbonate deposit-dominated barrier system is similar to, but different from the terrigenous barrier system. Information in the paper fully shows the distinguishing features of geomorphologic units, sediment assemblages, hydro-dynamic conditions of the carbonate barrier. The purpose of this paper is to provide an example for recognition and division of the ancient carbonate barrier.

Electrofacies technology was introduced in 1980 by Schlumbeger well Surveying Corp, but it only provided the service. This paper uses a method of Fuzzy mathematics to set up a mathematical model of electrofacies different from that of schlumbeger well Surveying Corp. Satisfactory electrofacies for the long curves of zhong 50 Well have been obtained in Zhongba Gas Field NorthWestern Sichuan Province.

Time-dependent characteristics of the have been found experimentally. It can be residual resistance factor (FRR) visualized as an additional residual effect (FARE) produced by the retained polymer molecules while of the injection water is changed. And the additional residual the flow-rate effect factor (FARE) has been defined. Theoretical analyses based on comformation changes of the polymer molecules in a varying flow field indicate that polymer viscoelastic property is essentially responsible for this effect.

The turbulent flow of plastic fluids in smooth pipes has been studied by using the stochastic theory of turbulent flow, and the formulas have been presented for evaluating the time average velocity in the whole section of pipes，mean velocity and friction factor, The results obtained from the study have shown that the influence of the yield stress of plastic fluids on turbulent flow is determined by ，The influence will be soon reduced as Re(z) increases or the diameter of pipe red aces. The influence of the yield stress on the dimensionless velocity profile is very small.

The course of saturation of core with one side vacuumized and the other injected is studied in this paper. By analysing the test data and explaining the saturation course of cores of different permeabilities, a general regularity is obtained，which is of great significance to directing the core saturation in relevent experiments.

In this paper, suspended pipelines with definite rigidity which cross over deep valleys or rivet's are studied by the method of differential operator. According to boundary conditions, the equation of flexibility and the equation of bending moment are determined. And then the internal stress and deformation of the suspended pipelines are obtained. An example is used here to compare with the flexible suspended cables.

By applying the regression analysis method，the relations between the abrasive wear volume of the friction surface material of a drilling of a drilling pump and its hardness，the piston material and the surface finish of the friction surface of the drilling pump are studied. The regression equation of the abrasive wear volume is set up. The working condition with minimum rate of wear is ascertained.
