近年来随着富台油田勘探成功,济阳坳陷新一轮潜山油气藏勘探顺利展开。作者根据渤海湾盆地区经历的大地构造演化,分析了济阳坳陷前中生界潜山所经历的构造背景和发育过程。指出古生代两次大隆大坳和轻度褶皱,为潜山构造带的形成奠定了基础;印支期的构造运动对潜山储层性能的提高起到重要作用;燕山晚期以来的张性块断作用,使得局部剥蚀潜山定型和断块潜山形成。济阳坳陷潜山型油气藏类型具有多样性、成带性,前中生代业已形成的大型潜山带是油气有利运聚方向,但不是整体富集带,而紧邻生油坳陷的各类潜山是勘探的重点部位。
In recent years, with the success of Futai oilfield exploration, a new round of buried hill reservoir exploration in Jiyang Depression commenced smoothly. Based on the evolution of the tectonic evolution experienced by the Bohai Bay basin, the authors analyzed the tectonic setting and development of the buried hills in the Pre-Mesozoic in the Jiyang Depression. It is pointed out that the Paleozoic two Dalongdaosu and slight fold have laid the foundation for the formation of buried hill structural belt. The Indosinian tectonic movement played an important role in the improvement of buried hill reservoir performance. Broken effect, making the partial erosion of buried hill stereotypes and fault block buried hill formation. The buried hill reservoirs in Jiyang Depression are diverse and banded. The large buried hill belts formed in the Mesozoic Mesozoic are favorable hydrocarbon migration and accumulation directions, but not the whole enrichment zone. However, Buried hill is a key part of exploration.
