针对塔河油田三叠系油藏油层薄、底水大的特点,形成了以水平井为主的开发模式。实践表明,影响水平井开发的关键技术主要有剩余油分布、隔夹层展布、轨迹控制程度、工作制度优化等。要高效利用水平井,提高单井产量和油田采收率,就需要以油藏精细描述和剩余油分布为基础,利用地质建模和数值模拟的方法,进行区块井网和参数优化,科学进行油藏管理,以实现效益最大化。

Due to thin sandstone reservoir and wide-distributed bottom water,horizontal well is themost common development pattern in Triassic of the Tahe Oil Field.The key factors influencing hori-zontal well development include residual oil and interbed distribution,trajectory control and workingsystem improvement.As to make good use of horizontal wells and to improve single well product andoilfield recovery,we should take reservoir accurate description and residual oil distribution as the base,use geological model and numerical simulation,improve regional well network and production parame-ter,and manage reservoir scientifically.Only in this way,can we make the greatest profit.
