Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.
利用该公式计算表明:当水平井长度一定时,存在一个最优井网形状,使得水平井的产能最大,在此基础上提出了水平井井网的优化方法;(5)提出了水平井无因次长度的概念,给出了联合井网最优井网形状因子与水平井无因次长度的关系式,并对水平井长度、油层厚度及井网面积对产能的影响进行了分析;(6)推导出了一无限水平井井排在XY 平面内势的解析解,为不同水平井整体开发井网或水平井和直井井网整体开发渗流理论的研究奠定了理论基础;(7)建立了交错式水平井与直井整体开发渗流理论,给出了拟三维条件下井网产能的精确解析解及该井网最优井网形状因子与水平井无因次长度的关系,并对产能的影响因素进行了分析;(8)建立了水平井与水平井正排列井网、交错排列井网条件下渗流理论及井网产能在拟三维条件下的精确解析解,给出了交错井网条件下最优井网形状因子与水平井无因次长度的关系,通过与正方形井网对比,说明优化井网可大幅度提高开采效果;(9)建立了分支水平井和直井面积井网水油两相非活塞驱替条件下渗流问题的解析解,给出了见水前后无因次产量与无因次时间的关系式以及见水时间等。

One has proved that the viewpoint that the horizontal sidetrack is the most important technology for exploiting "large scale"unswept remaining oil in mature oilfields from three aspects.They are:(1) the horizontal sidetrack is the main technology for exploiting primary rich areas of"large scale"unswept remaining oil in mature oilfields;(2) the horizontal sidetrack can hit any rich area of"large scale"unswept remaining oil in reservoirs;(3) the cost of the horizontal sidetrack is more low in contrast with the vertical well and the conventional horizontal well.
从三方面论证了侧钻水平井是开采成熟油田&大尺度&未波及剩余油最重要的技术这一观点:①侧钻水平井是开采成熟油田&大尺度&未波及剩余油主要富集区的主要技术;②侧钻水平井可钻达油层中任何部位的&大尺度&未波及剩余油富集区;③侧钻水平井比钻垂直井和常规水平井费用低得多、更加经济。
