In view of geology feature in superficial layer of oil field,the adaptability of rectangular pattern by hydraulic-fracturing integral fracturing optimization design software in this area is studied. Considering the change of ratio of fracture length to distance between wells and flow conductivity under different well array,it calculates such development indexes as daily rate and cumulative production.Moreover it discusses the adaptability of rectangular pattern,the reverse rhombus 9-spot and reverse square 9-spot.The results shows that for the rectangle pattern with fixed well spacing,it is not necessary that larger well array,larger ratio of fracture length to distance between wells and lager flow conductivity will lead to better post fracture effect. Instead, there exists a reasonable range. By study, the decrease of daily rate of rectangular pattern is the lowest of all, cumulative production is the largest. Therefore rectangle pattern is suited in oilfield. The best proportion is, fracture conductivity about 40 μm2·cm,when ratio of fracture length to distance between well is 0.1,the well line and well spacing about 300 m×250 m, if it choose 0.2, the well line and well spacing may about 400 m×300 m.
