【摘要】 巴东油田K层为高孔低渗型的灰岩层 ,在开发方案的编制过程中 ,需要对该油田的直井、水平井和定向斜井 (井眼斜穿油层 )进行产能预测。文中利用等效直井方法计算得出了这 3种不同结构油井的产液指数随含水的变化规律 ,具体分析了水平段长度、泄油半径和井斜角大小对产能的影响 ,并对 3种不同结构井的产能进行了比较。更多还原

【Abstract】 Formation K is the high-porous and low-permeability limestone in Badong Oilfield. According to its characteristics,it is necessary to predict the productivity of the vertical wells,horizontal wells and directional wells during setting development program.In this paper,the changing regularity of liquid-producing index vs.water content ratio in three types wells is calculated by the equivalent straight well method.The influence of the horizontal length,drainage radius and deviation angle on the productivity is analysed,and finally compare the productivity of three structural wells.更多还原
