摘要:
泌阳凹陷下二门地区油气资源丰富，油藏类型以断层－岩性油气藏为主，断裂特征与砂体展布的配置关系是该区油气勘探的主控因素。笔者综合3D地震、钻测井、岩心资料，以古近系核桃园组三段Ⅳ油组1小层（Eh3Ⅳ1）为例，通过精细构造解析、断层活动性定量分析和砂体展布特征刻画，从构造活动−沉积响应的角度分析生长断层对辫状河三角洲砂体展布的控制作用。结果表明，下二门地区主要发育一系列SW−NE转近E−W走向的北倾生长正断层，剖面形态呈阶梯状断层组合，各条断层沿走向活动性差异明显。研究区主要发育侯庄辫状河三角洲前缘亚相和前三角洲亚相，平面上来自北部的水下分流河道砂体在断层转换带或同一断层活动性较弱部位易通过，而在活动性较强部位受到限制或转向。垂向上，通过活动性较弱区域砂体垂向连续叠置、加厚发育，通过活动性较强区域砂体垂向间歇分散、减薄发育。该研究可为东部断陷盆地低序级生长断层发育区砂体展布规律认识和断层−岩性油气藏勘探开发提供一定借鉴。
Abstract:Xiaermen area of Biyang sag is rich in oil and gas resources. The reservoir type is mainly fault-lithologic reservoir. The configuration relationship between fault characteristics and sand body distribution is the main controlling factor of oil and gas exploration in this area. Based on 3D seismic, drilling, logging and core data, taking the Small layer 1 of Ⅳ oil formation in the third member of Paleogene Hetaoyuan Formation (Eh3Ⅳ1) as an example, through structure analysis, quantitative analysis of fault activity and characterization of sand body distribution characteristics, this paper analyzes the distribution characteristics of Braided River Delta sand body controlled by growth fault from the perspective of tectonic activity sedimentary response. The results show that a series of North dipping growth normal faults with SW-NE turning to E-W strike are mainly developed in Xiaermen area. The profile forms a stepped fault combination, and the activity of each fault is obviously different along the strike. The study area mainly develops Houzhuang braided river delta front subfacies and pre delta subfacies. The underwater distributary channel sand body from the north is easy to pass through the fault transition zone or the weak part of the same fault activity, but is limited or turned in the strong part. Vertically, sand bodies in areas with weak activity are vertically continuously superimposed and thickened, while sand bodies in areas with strong activity are vertically intermittently dispersed and thinned. This study can provide some reference for the understanding of sand body distribution law and exploration & development in the low order growth fault development area of the eastern fault basin.
