摘要/Abstract

摘要： 以百口泉油田检188断块克上组油藏为例,总结了如何提高非均质、薄层、低饱和砾岩油藏开发效果的做法:针对低饱和油藏地饱压差大的特点,充分利用油藏弹性能量,采取先转抽求产;当地层压力降到一定程度后,在短期内完成注水井的转注工作,进行温和注水,控制注采比,合理补充地层能量,以扩大注水波及体积;注水见效后再及时放大生产压差生产,进行合理的动态调配,进一步扩大注水效果;对油井进行增产措施;对水井进行地面分注,对注不进、注水不满足井进行增注等措施,进一步扩大注水波及系数,提高了油藏的采收率。

Abstract: Using an example from Baikouquan oilfield, we summarize how the improved performance of thin, heterogeneous conglomerate reservoir with low fluid saturation can be achieved. In view of larger saturated pressure different present in the low-saturation reservoir, oil production started with pumping for higher production; when the reservoir pressure declined to some extent, mild water injection began at a reasonable injection-production ratio to improve the sweep volume; after the waterflooding response was observed, production was under way at elevated pressure drop to furthur improve the waterflooding performance; well stimulation was undertaken; separated injection on surface and enhanced injection in the wells with no injection and inadequate injection were done for additional sweep improvement and then for enhanced oil recovery.
