Discovery and significance of subtle buried hills in Jiyang Depression, Bohai Bay Basin
-
摘要: 针对渤海湾盆地济阳坳陷下古生界碳酸盐岩潜山勘探陷入低谷，勘探方向不明的实际情况，通过深入分析其成藏条件，特别是圈闭有效性问题，打破了传统成藏模式束缚，取得了勘探的成功。新发现了埕北313负向构造型、埕北古斜14斜坡型和陈家庄侧向对接高渗透储层型等3种新的潜山油气成藏模式。这3种新的模式使早期认为没有勘探潜力的潜山负向构造带、圈闭有效性差的斜坡带和圈闭侧向不封堵的潜山断块成为有利的勘探目标区。从断层活动特征角度对圈闭有效性进行了分析，同时提出了"类砂泥岩"潜山储层发育模式，为潜山圈闭有效性分析提供了一个全新的思路。Abstract: The exploration of carbonate buried-hills in the Lower Paleozoic in the Jiyang Depression of the Bohai Bay Basin are at a minimum now, and the exploration targets are not clear. Hydrocarbon accumulation conditions were analyzed, especially the effectiveness of traps, which broke the shackles of traditional accumulation models and achieved exploration success. Three new buried-hill reservoir models have been discovered, namely the Chengbei 313 negative structure, the Chengbei Guxie 14 slope, and the Chengjiazhuang laterally adjacent high-permeability reservoirs. These three new models make the buried-hill negative structure, the slope zone with poor trap effectiveness, and the laterally unblocked buried hill fault blocks that were considered to have no exploration potential earlier become favorable exploration targets. The effectiveness of traps was analyzed from the aspects of fault activity characteristics. At the same time, a development model of 'sand-like mudstone' buried hill reservoirs was provided, which provided a new idea for the effectiveness analysis of buried hill traps.
