The results show that the water breakthrough time shortens with the increase of the horizontal well length. Under the same well space and production conditions, the water breakthrough time of five-spot pattern is longer than that of seven-spot and nine-spot pattern. With the increase of angle between the horizontal well and the horizontal direction, the water breakthrough time shortens in five-spot well pattern, firstly increases and then decreases in seven-spot pattern, and increases in nine-spot pattern. The influence of reservoir and fluid parameters on the water breakthough time is little.

In order to find out a simple and efficient method to calculate the water breakthrough time in combination well pattern of horizontal and vertical wells, simplifing a horizontal well into a vertical well with the same well-hole radius, and considering the unpiston-like displacement, the water breakthrough time formulas of five-spot, seven-spot and nine-spot pattern were derived and revised by equivalent percolating resistance method. In this method, the percolation region is divided into three resistance regions.
