摘要
L1井区油藏为低孔特低渗透油藏,水平井压裂改造技术是L1井区水平井主要投产方式,为了取得更好的开发效果,需要对其井网形式进行研究。基于L1井区实际地质模型,建立了10种联合井网数值模型,对比不同井网形式下的开发指标发现:直井注压裂水平井采的五点法井网是L1井区首选联合井网。
L1 well block has low porosity and ultra- low permeability reservoirs, which are produced by the horizontal well fracturing technology. In order to achieve better development effect, the research of well pattern is needed. Based on the actual geological model of L1 well block, 10 kinds of combined well network numerical models were established. By comparing the development indexes under different well network, it is found that the preferred well pattern in L1 well block is the five -point pattern having vertical injection wells and horizontal producing wells by fracturing.
