The combined production of vertical and horizontal wells can make horizontal well production rates be 2 to 5 times greater than unstimulated vertical well rates, but the areal sweep efficiency is less than that of vertical well pattern untill when the perforation ratio is greater then a certain value, which depends on the pattern of the combination. Seven spot pattern of the combination of vertical and horizontal wells has some advantages over others.

当水平井和直井联合面积布井时，在同样的压差下，水平井的产量要高于相应直井井网的直井产量的2～5倍，但只有当穿透比达到一定程度，或水平井达到一定长度时，其波及系数才高于相应直井井网的波及系数（五点法井网的穿透比界限为0.521，七点法井网的穿透比界限为0.430），因而在水平井开发油气田时，必须保证水平井一定的长度，这样从长远的观点，水平井才能显示出优势，对比性分析表明，水平井和直井的七点法联合布井和直井井网以及水平井和直井的五点法联合布井井网相比，具有一定的优势，数值模拟表明，在水平井和直井的联合面积布井的各种方式中，改进的九点井网是一种较好可取的布井方式。
