摘　　要：目前由于低渗透油藏井网的不合理,导致开发过程中部分油井的过早水淹、注入水无效循环严重,难以建立有效的压力驱替系统。因此建立合理的井网形式和井排距,对提高低渗透油藏的开发水平具有十分重要的意义。以姬塬低渗透油田长8油藏为例,通过对罗1区块数值模拟研究,确定出适合的井网形式。根据油藏基质渗透率和裂缝密度,确定出适合的井排距。At present, due to unreasonable low-permeability reservoir well network, some wells flood in the process of developing premature, and water injection invalidly cycle severely, it is difficult to establish an effective pressure displacement system. Therefore, the establishment of a reasonable well pattern and well row spacing is important to improve the level of development of low permeability reservoir. In the eighth reservoir of Jiyuan low-permeability oilfield, for example, through the numerical simulation of Luo 1, the suitable block well pattern was determined. According to the reservoir matrix permeability and fracture density, the appropriate well row spacing was determined.
