There exists the optimal value of space between side laterals, which is similar to the existence of the optimal well pattern and pattern well spacing in vertical well section production mode.

与直井区块开采方式存在最优井网和井距类似，在井的基本结构确定之后，存在最优的分支间距；

It shows that the communication degree of various patterns of reservoirs has certain relation among reservoir pattern and well spacing.

研究表明，不同形态储层的连通程度与储层形态和井距有一定的关系。

Based on low productivity and injectivity of a well for low permeability reservoirs, close well pattern and well spacing must be performed.

低渗透油层低的单井采油能力和吸水能力注定了低渗透油藏必须采用密井网和油水井数比低的井网。
