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.

But the proliferation of rules, and the fact that selectWikipedians have learnt how to handle them to win arguments, now represents adanger, says Andrew Lih, a former deletionist who is now an inclusionist, andwho is writing a book about Wikipedia.

依据 Andrew Lih 的观点，规则的无限扩大、某些熟谙规则的维基客利用规则来赢得讨论，这也带来一种危险。他曾是删除派一员，如今则是保留派的支持者，目前正在创作一本关于维基百科的专著。
