【摘要】：大庆葡南油田黑帝庙油层的试油工作于1967年开始,但到目前为止,黑帝庙浅层气仍处于评价阶段,尚未进行大规模开发。葡南葡194-16井区位于葡萄花油田南部葡南鼻状构造带,面积约12.6km2,是目前黑帝庙层重要的油气增储潜力区。自2007年起,在葡194-16井区开展了多次试气工作,油气显示良好,针对葡南油田田田黑帝庙油层砂体分布规律及油水分布特征研究作为油田开发的地质依据,成为推进勘探开发工作的核心和重点。本文以层序地层学、沉积岩石学、石油地质学等油气田开发地质相关理论作为基础,以大庆葡萄油田黑帝庙油层为研究目标,结合研究区实际勘探开发数据,利用三维高分辨地震、储层反演预测、AVO烃类检测、套后中子资料分析等技术手段,开展研究区的构造特征、储层特征以及油水分布规律开展地质规律再认识研究。结果表明:葡194-16井区位于葡萄花构造向西南延伸部分的葡西鼻状构造带西侧葡-1号构造内,为典型的断鼻型构造圈闭,是葡西鼻状构造被19号断层切割形成的,且断裂深度较大,在三层构造图上均有明显发育。根据砂体等值图,HⅠ组油层组砂岩发育明显优于HⅡ组,其中HⅠ 2、HⅠ 3、HⅠ 5最为发育,其次是HⅠ 4、H Ⅰ6, HⅡ组除HⅡ1有不足2m的砂体发育外,其余分层组砂体均不发育;葡194-16井区砂体平面和纵向非均质性突出,纵向薄互层且层数多,平面相变快。单井纵向砂体总数平均23.4m,平均单层钻遇厚度为2.7m,且有21.5%的单井无5m以上的砂体发育;平面表现为砂体孤立、无连通,砂体厚度变化快。葡194-16井区为构造—岩性油气藏,含油气富集程度取决于砂体与局部构造的配置。圈闭内为油气层,砂体规模大,油气水可以在局部构造内分异;圈闭外为水层,砂体规模小,含油气连续性差。通过构造精细解剖、储层精细描述、油水精细分析等一系列工作的开展,在研究区的构造特征、储层刻画以及剩余油分布规律清晰认识的基础上,落实油气水关系,明确油藏类型,结合区域AVO烃类检测资料、套后中子资料、试油井、生产井等资料,将研究井区油气潜力分布分为三个级别,实现油气富集有利区预测与评价,为葡194-16井区黑帝庙层的进一步布井开发提供有力的理论依据和技术支持。
[Abstract]:The test work of Heidimiao reservoir in Punan oilfield of Daqing began in 1967, but up to now, the shallow gas of Heidimiao oil field is still in the evaluation stage and has not been developed on a large scale. Well area 194-16 is located in the southern Punan nose structural zone of Putaohua Oilfield with an area of about 12.6km2. It is an important oil and gas accumulation potential area in Heidimiao formation at present. Since 2007, many gas tests have been carried out in Pu194-16 well area, and the oil and gas show well. According to the distribution law of sand body and oil-water distribution characteristics of Hedimiao oil reservoir in Punan Oilfield, the research is used as the geological basis for oilfield development. To become the core and focus of the exploration and development work. Based on the related theories of sequence stratigraphy, sedimentary petrology, petroleum geology and other oil and gas fields, this paper takes the Heidimiao reservoir of Daqing Grape Oilfield as the research object, and combines the actual exploration and development data of the study area. By means of 3-D high-resolution earthquake, reservoir inversion prediction, AVO hydrocarbon detection, post-neutron data analysis and other technical means, the structural characteristics, reservoir characteristics and oil-water distribution law of the study area are studied again. The results show that the Pu-194-16 well area is located in the west side of the Puxi nasal structural belt extending southwest of the Puxi nose structure belt. It is a typical fault nose type structural trap formed by the cut of the Puxi nose structure by fault No. 19. The fault depth is very deep, and it is obviously developed on the three-layer structural map. According to the sand body equivalent diagram, the sandstone development of H 鈪，
