【Abstract】 According to the law of equivalent percolation resistance, the productivities of mixed well patterns of horizontal well or multilateral horizontal well with vertical well are studied. In steady flow condition, the formulae of the well pattern in common use which are 5-spot pattern, 7-spot pattern and 9-spot pattern are given. The results show that: (1) The equivalent percolation resistance law is applicable and accurate enough to be used in productivity calculation of horizontal well pattern; (2) The productivity of mixed well pattern can be used to small well pattern; (3) The production formulae constructed in this paper are based on area well pattern, which can be applied to development program design and performance prediction.更多还原
