试井及生产资料在储气库早期评价中的应用

针对陕224井区储量、储层连通性、边界封闭性不确定的问题,运用压力恢复试井与生产动态分析相结合的方法,通过压力恢复曲线拟合,确定近井地带特性参数,如井筒储集系数、表皮系数,并获得4组储层及边界解释模型;利用流量标准化拟压力曲线拟合校正了解释模型,求取到气藏关键参数,如地层系数、径向复合半径、流度系数比、储容系数比、边界位置,计算井区共动用储量10.43×108m3。研究表明,试井与生产动态分析相结合的方法,弥补了资料周期短、精度低的缺陷,克服了解释模型不全面、不唯一的弊端,获得了完整准确的井区气藏模型。

Hydrodynamics of Supercavitating Bodies at an Angle of Attacks under Conditions of Considerable Effect of Fluid Weightiness and Closeness of Free Border

We present the results of theoretical and experimental studies of flow processes of extended axisymmetric cavitators during motion near a free surface taking into account a considerable effect of fluid weightiness. The main objective of work is to study ways of reduction of fluid weightiness effect using lift at cavitator and other body （hull） elements within a cavity, in order to apply this way of drag reduction for a range of considerably lower motion speeds.
