Abstract: The paper mainly studys the productivity of a horizontal well pattern,and compares theconing parameters between horizontal wells and vertical wells in a resevoir with bottom water drive,First,the paper applies the method of image and superimposed criterion of poten-tial function to derive the productivity formula of horizontal well pattern,In the process ofderivation,the factors,such as impermeable boundary on the top of oil bearing formation,onstant pressure boundary,the position of horizontal wells in the oil bearing formation,anistropy of oil bearing formation,which have influence on potential distribution,are con-sidered in the derivation of the potential distribution expression and productivity formula of ahorizontal well pattern in a reservoir with bottom-water drive,Second,this paper comparesthe key factors which control coning in horizontal wells and vertical wells,these parametersare:(1) anistropic ratio,(2) oil viscosity,(3) well spacing,(4) water-oil density contrast,(5) oil zone thickness.

Key words: bottom water drive, horizontal well, well pattern, productivity formula coning parameters

摘要： 主要研究底水驱油藏水平井井网产能公式和影响水平井、垂直井锥进参数的比较.应用镜像法和势函数叠加原理推导水平井井网产能公式,在推导过程中,考虑了油层顶部封闭边界、垣压边界、水平井在油层中位置、油层各向异性等因素对水平并势分布的影响,推导出底水驱油藏水平井井网势分布函数及其产能公式.比较控制水平井和垂直井锥进的关键参数,这些参数是:油层各向异性比值、原油粘度、井距、油水密度差、油层厚度.
