渤深6潜山带油气藏特征

渤深6井发现了富集高产的下古生界潜山油藏。地震、钻井和成像测井资料的研究表明,潜山带油气藏类型主要有潜山风化壳型和内幕型两类,储集空间以裂缝、溶洞为主。地层结构、构造特征分析表明,该区下古生界具备有利的成藏条件,油气分布明显受油源控制,紧邻油源的潜山断块具有较大的勘探潜力。

Boshen 6 buried hill belt reservoir characteristic

A rich and high-productivity reservoir has been discovered at late palaeozoic buried hill by drilling Boshen 6. The seismic, drilling and logging data shows that types of the reservoirs can be divided into crust and inside hill, the reservoir space are mainly fracture and solution cavity. The structures and characteristics of stratum in this area show a favorable reservoir-forming condition at bottom palaeozoic, the distribution of reservoirs were controlled by sources, the buried hill faults near the oil sources are of most exploration potential.
