临清拗陷地震剖面的特征,可以划分为四个地震反射构造层,其反射特征和相互关系表明:拗陷形成于中立代中期;早第三纪为拗陷的发展期,同时形成了凹陷和凸起,晚第三纪早期,拗陷开始萎缩直至消亡。不同发展期有不同沉积环境,因而形成了不同生油能力的生油岩。为数不多的钻井资料,揭示了这些生油岩的存在,但还未完全揭示整个拗陷的含油远景。拗陷的一级构造单元具单断结构,呈北北东带状分布,高低相间。局部构造呈带状分布,多数位于大断层下降盘,为被断层破坏了的半背斜型。大部分局部构造形成于早第三纪且分布在东部和南部。总结已揭示的石油地质及构造特征,临清拗陷可能有五种主要油气藏类型,东部应是石油勘探的重点。
The characteristics of the seismic profile of the Linqing depression can be divided into four seismic reflection structural layers. The reflection features and correlations show that the depression was formed in the middle-mid-Mesozoic. Early Tertiary was the development of the depression and formed the depression And raised, Late Early Tertiary, the depression began to shrink until its demise. There are different depositional environments in different developmental stages, thus forming source rocks with different oil generation ability. The few drilling data reveal the existence of these source rocks, but the oil outlook of the entire depression has not yet been fully revealed. The first-order tectonic units in the depression have a single-break structure with north-north east belt distribution and high and low phases. The local structure is zonal distribution, most of them are located in the large fault downdip, which is a half-bevel type destroyed by faults. Most of the local structure formed in the early Tertiary and distributed in the east and south. Summarizing the revealed petroleum geology and tectonic features, there may be five major reservoir types in the Linqing depression, and the east should be the focus of petroleum exploration.
