And Function

This paper firstly explained the working principle of Subsea Control Module (SCM) and function and performance of the electro-hydraulic control valves, and then mathematical model of the electro-hydraulic control valve in SCM was analyzed. The test board was designed according to characters of hydraulic system of the test stand. And on the basis of these, an effective testing method of the electro-hydraulic control valve in SCM has been defined. According to the test method of hydraulic system, we built and analyzed a model of the hydraulic test system by using the AMESim software. Based on the analysis results, the judgments whether or not the test stand could meet the requirements is made.

Two kinds of nonmetallic pipes, steel skeleton polythene plastic composite pipe and reinforced plastic composite pipe, whose application effect in oilfield are preferable, were chosen as the research objects in this paper. An indoor experiment apparatus was established to measure the on-way resistance of this two kinds of pipes under different flow rates. Then many hydraulic calculation formulas were used to calculate the on-way head loss of tested pipes and the relation curves of pressure drop gradient on flow velocity and Reynolds Number were drawn. According to the comparison of calculated value and measured data, appropriate calculation formulas of on-way head loss for the two nonmetallic pipes were sorted out respectively. The result shows that as for steel skeleton polythene plastic composite pipe and reinforced plastic composite pipe, Panhandle A formula and Drew Et al Formula are recommended respectively to calculate the on-way hydraulic computation.
