摘要

小草湖地区油气资源丰富,勘探程度低、潜力大,随着油气勘探的不断深入,构造型气藏越来越少。通过深入研究台北凹陷小草湖地区天然气成藏条件,总结气藏成藏模式,认为气藏总体受构造、岩性、断层三重因素控制,其中岩性、断层遮挡是成藏最关键的控制因素。该区岩性气藏勘探立足2 个鼻隆区和洼内,积极扩展外围区块,遵循多砂体叠合连片含气成藏模式,开展精细气藏描述。沿鼻隆脊部钻探低部位河道砂体获得成功,实现了疙7 —红台2 号含油气区的复合连片。

Abstract

Xiaocaohu area is rich in hydrocarbon resources with low degree of exploration and high potential . With the exploration increasing, structural reservoirs become rare, while the difficulty of the stratigraphic-lithologic reservoirs increase. According to the research on the accumulation conditions of the natural gas in Xiaocaohu area, Taibei Sag, the accumulation mode was discussed. The result showed that the reservoirs are cont rolled by structure, lithology and fault, among which lithology and fault are the key factors controlling the accumulation. On the basis of the exploration of lithologic reservoirs in two nose-shaped uplifts and sag, extending periphery block was carried out to develop fine gas reservoir description. The drilling of lower channel sand bodies along the ridge of the nose-shaped uplift is successful, making Ge 7 to Hongtai 2 a continuous oil/ gasbearing area.
