合理的井网可以利用开发初期采油速度高的优势,尽可能延长无水采油期,提高开发初期的采油速度;获得较高的最终采收率;有利于区块残余油的驱替;通过井网参数的设计,包括井网的选择和井网密度的计算,最终可以取得较好的经济效益。 Reasonable well pattern can take advantage of the high oil recovery rate in the initial stage of development, prolong the dry recovery period as much as possible, increase the recovery rate in the early stage of development, obtain higher ultimate recovery rate, facilitate the displacement of residual oil in the block, The design of the network parameters, including the selection of the well pattern and the calculation of the well pattern density, can ultimately achieve better economic benefits.
