The result shows that in the combined pattern of hydraulically fractured horizontal well and vertical well,the azimuth of the horizontal well is optimum in parallel to the smallest terrestrial stress;inverted nine-spot pattern shall be adopted;the limit drainage radius for F147 reservoir is 110m with consideration of threshold pressure gradient;the optimum well pattern and spacing is 400 m × 200 m(well spacing × array spacing).
结果表明:该块压裂水平井与直井联合布井井网方位应以水平井位置平行于最小地应力方向为最优;井网类型应选择反九点井网;考虑启动压力梯度下F147区块极限供油半径为110 m;井网井距应该选择400 m×200 m(井距×排距)为最优。
