摘 要：
钟市油田是一个超覆沉积在荆沙组剥蚀面上的多层叠瓦状砂岩油藏,具有岩性复杂、含油层组多、油砂体多、油藏类型多、断层多、油水关系复杂等诸多难点。通过油藏精细构造和地质研究,在细分层系的基础上,重新归位重组井网。采用老区补缺、扩边等方式,完善注采井网,提高储量动用和水驱动用程度,有效改善了油藏水驱开发效果。2011~2013年年均含水上升率均为负值,注采对应率由50.6%上升为62.4%。累计年产油量增加3.49×104t。

摘 要：
Zhongshi Oilfield was a multilayer imbricate sandstone reservoir with overlap sedimentary deposited on the surface of Jingsha Erosion Surface.There were lots of problems such as complex lithology,many oil-bearing strata,many sand bodies and many types of reservoirs,many faulted zones and with complex oil-water relationship and so on.By the research of fine structures and reservoir geology and based on a series of strata subdivision,the well patterns were reorganized,by way of filling vacancy wells and expanded drilling in old oil regions,the injection-production well patterns were perfected for improving the effect of reservoir waterflooding.From 2011 to 2013,the average annual water-cut increase has been negative,the corresponding injection-production rate is raised from 50.6% to 62.4%.The cumulative annual oil production increase is 3.49 × 104 t.
