摘要
胜北—盐家地区被陈南、胜北和罗西断裂分为3个区域,不同的断层活动时间和强度对区域的影响也不同。沙四段早期,盐家—胜北地区整体呈退积序列;沙四段晚期,盐家、胜北地区沉积有差异。其中,盐家地区地层整体北高南低,砂砾岩体仍然呈退积序列;根据断层活动不同,胜北断层上升盘地层分为北高南低台阶式和反向洼斗式两种;胜北断层下降盘的沉积形态及储层分布与断层活动密切相关。
The Shengbei-Yanjia area is divided into three regions by Chennan fracture, Shengbei fracture and Luoxifracture, and the fault activities in different time and intensity give different impacts on different regions. Thesedimentary sequences were retrograding sequence in the early of Es4 in whole Shengbei-Yanjia area, but weredifferent in the late of Es4 between the Shengbei and Yanjia area. The stratas are entirely high in the north and lowin the south in Yanjia area and the glutenite bodies are still retrograding sequence. According to the different faultactivities, the upthrow side of the Shengbei fault could be divided into step type which is high in the north and lowin the south and inverted bucket type, the sedimentary pattern and reservoir distribution are closely related to thefault activity in the downthrow of the Shengbei fault.
