摘要:

随着非常规油气勘探进入快速发展阶段,中国致密油气勘探取得了丰硕成果。基于多年非常规油气勘探实践,结合陆相断陷盆地致密油藏特征,初步将中国陆相盆地致密油藏分为致密砂岩油藏和特殊岩性致密油藏。特殊岩性致密油藏包括泥灰岩型致密油藏、碳酸盐砾岩型致密油藏、凝灰岩型致密油藏等。与常规致密砂岩油藏相比,特殊岩性致密油藏储层成因特殊,储集空间类型多样,常规地球物理方法预测困难。通过对冀中坳陷束鹿凹陷沙河街组三段下亚段泥灰岩-砾岩致密油藏的解剖,建立了束鹿地区特殊岩性致密油藏的成藏模式。对于特殊岩性致密油藏的勘探,需要多因素综合分析,总结致密油成藏控制因素,建立适合探区的油气成藏模式,以此指导后续勘探开发。

Abstract:

With rapid development of unconventional hydrocarbon exploration industry, fruitful results have been achieved in China's tight oil and gas exploration. Based on multi-year unconventional hydrocarbon exploration as well as characteristics of tight oil reservoirs in continental rift basins, tight oil reservoirs in China's continental basins can be preliminarily classified into tight sandstone reservoirs and special-lithology tight reservoirs; the latter include calcilutite tight reservoirs, rudstone tight reservoirs, tuff tight reservoirs and etc. As compared with conventional tight sandstone reservoirs, special-lithology tight reservoirs have special genesis and diversified reserving space types, which are difficult to predict using conventional geophysical methods. Through detailed research on calcilutite-calcirudite tight reservoirs in the lower part of Member 3 of Shahejie Formation, Shulu sag, hydrocarbon accumulation mode of special-lithology tight reservoirs was established. Multi-factor comprehensive analysis is required for exploration of special-lithology tight reservoirs. Meanwhile, it needs to summarize control factors for tight reservoir accumulation and establish applicable hydrocarbon accumulation modes for exploration areas, thus guiding the follow-up exploration and development.
