摘要
对巨厚古潜山油藏水平井开发可行性及合理注水方式进行了研究。结果表明,巨厚古潜山油藏裂缝溶洞发育,采用水平井开发能够获得较高的产能;采用底部注水时,由于储层的非均质性及重力作用,上部生产层注水难以受效,采用逐层上返注水方式能使注入水均匀向上推进,获得较高的水驱采收率,取得了很好的开发效果。
How to effectively and reasonably develop ultra-thick buried hill is a challenging research field. The development feasibility of horizontal well and reasonable water flooding pattern research of Ultra-thick buried-hill reservoir were investigated. The results show that a high single well output can be acquired by horizontal well in ultra-thick buried-hill reservoir where cave and fracture are highly developed. An ideal development performance can be acquired by bottom water flooding for the reservoir which is not very thick. But for ultra-thick buried-hill reservoir, top layer has a relatively poor flooding response by bottom water flooding new zone-by-zone water flooding development from bottom is applied in this ultra thick buried reservoir with a high oil recovery rate.
