Abstract

Abstract:

Through more than five decades of exploration and development, Qikou sag of Huanghua depression has entered a high exploration stage. It is more and more difficult to detect a large-scale structural hydrocarbon reservoir, and the lithologic hydrocarbon reservoir in slope areas has become the exploration focus. Based on the total research and dissection of the whole sag, the geological differentiation characteristics of large-scale gentle slope area were discussed to propose new understandings about the gentle slope areas with triple division properties, i.e., each slope area can be divided into high slope, middle slope and low slope. Three kinds of slope have different source-reservoir-cap assemblages with obviously different accumulation and distribution of oil and gas. In the high slope, the trench region is able to control the sand, rich in dominant migration and convergence phase. In the middle slope, slope break belt is able to control the sand, rich in dominant tectonic lithological phase. In the low slope, distal fan is able to control the sand, rich in dominant source-reservoir coupling phase. Determined by the effective allocation of large slopes, sand bodies and source rocks, the slope area has the conditions to form large-area lithological stratigraphic reservoirs. Through exploration practices, major discoveries have been made in three slope areas of Qikou sag, i.e., Chengbei, Qibei and Banqiao, proving that the slope area is one of the main targets of hydrocarbon pre-exploration and breakthrough as well as large-scale reservoir formation in faulted basins.

Key words: slope area, lithologic oil and gas reservoirs, hydrocarbon accumulation, oil in the higher formation while gas in the lower formation, Paleogene, Qikou sag

摘要：

经过50多年的勘探开发，黄骅坳陷歧口凹陷已经进入高勘探阶段，寻找大规模构造油气藏的难度越来越大，斜坡区地层-岩性油气藏成为勘探的重点。在凹陷整体研究解剖的基础上，探讨了大型缓坡区地质分异特征，提出了缓坡区高、中、低三分性的新认识，高、中、低斜坡生储盖组合配置不同，油气运聚与分布差异明显。高斜坡沟槽控砂，优势运移汇聚相富集；中斜坡坡折控砂，优势构造岩性相富集；低斜坡远扇控砂，优势源储耦合相富集。大型斜坡、砂体、烃源岩的有效配置决定了斜坡区具有形成大面积地层-岩性油气藏的条件。经勘探实践，在歧口凹陷埕北、歧北和板桥三个斜坡区均获重大发现，并实现了规模增储，证实了斜坡区是断陷湖盆内油气预探突破与规模增储的主要方向之一。
