改善检188井区克上组油藏注水开发效果技术研究

Study on the Technology for Improving Waterflooding Development Effectiveness of Keshang Formation Reservoir in Jian188 Well Area

针对检188井区克上组油藏在开发中存在的突出问题,开展综合治理研究。通过提高系统压力,改善油层注水能力。在逐步恢复地层能量的基础上,按照"分区分治"原则开展注采结构调整,通过治理达到减缓油藏递减和改善油藏水驱状况的目的。

According to the prominent problems in the development process of Keshang formation reservoir in Jian188 well area, comprehensive research was carried out. It＇s pointed out that the system pressure should be increased to improve reservoir water flooding ability. On the basis of gradually restoring formation energy, the injection production structure of every block should be adjusted based on actual situation of the block in order to slow down the oil production decline rate and improve the reservoir water flooding condition.
