1. It only costs a five-spot.

2. Adjusted the well pattern from inverted nine-spot to five-spot will improve the oil production and recovery.

3. Finally, the planned paths are smoothed by adopted the five-spot triple smoothing algorithm.

4. At present, more integral fracturing design research focus on five-spot well network and nine - spot well network but little on rhombus anti - nine- spot well network.

5. The new maths model can be apply to forecasting of line drive gas injection, and can be popularized to five-spot and other areal well pattern.

6. Four branches should be taken for the radial multilateral horizontal in five-spot well pattern. At the same time, branch length should be long based on the drilling technology and drilling security.
