大庆三肇地区扶杨油层剩余有利目标区优选
|
摘要
三肇地区经历了近四十年的油气勘探,已经成为一个重要的油田区。该区扶杨油层储层为低孔、低渗储层,油气分布规律复杂,勘探开发成本高。为降低勘探开发成本,搞清油气分布规律,为今后的勘探开发提供可靠的地质依据,有必要对扶杨油层进行沉积相和有利目标区研究。
通过对取心井的岩石学特征、单井剖面相分析,结合区域沉积背景,总结了三肇地区扶杨油层的主要沉积相类型及特征,确定三肇地区扶杨油层为三角洲平原和三角洲前缘沉积。通过沉积相平面图、砂岩等厚图的分析对比,阐述了三肇地区扶杨油层沉积相的平面分布特征及砂体展布规律。
通过对三肇地区扶杨油层物性资料和油藏剖面分析来看,该区扶杨油层油水平面分布表现为不同构造、不同区块油水界面不统一,呈波状变化,呈现多套、多构造单元油气水组合。整体上具有含油连片性,但受构造高低、断层发育、岩性和物性的影响,不同断块含油富集程度差别较大,一般的地垒块、断裂带发育周围油气连片分布且相对富集。
在此研究的基础上应用控藏要素多元叠合法制定二类有利区的优选原则,并预测和优选出了二类含油有利区;在此基础上提出了部署原则,并为下一步的工作提出了具体的实施要求。
Atfer about forty years prospecting and developing,Sanzhao Area has become the important oilfield. Because Fu-yang oil bed is low porosity and low permeability reservoir and the oil distribution is complex,the cost of exploration is very high. In order reducing the cost of the exploration and development,finding out the rule of the oil and gas distribution,providing the credibility geology gist for the further exploration and development,it is necessary to research the sedimentary facies and main target district.
Through the analysis of petrology characteristics and individual well section of sedimentary facies of core holes,main facies types and its features of Fu-yang oil bed in Sanzhao area are summarized on the basis of sedimentary background of region. The sedimentary facies of this area are delta plain facies and delta front facies. By the analysis and contrast of plans of sedimentary facies and isopach maps of sandstone, the planar characteristics of distribution of sedimentary facies and sand bodies of Fu-yang oil bed in Sanzhao area are elaborated.
Through analysis of physical property information and oil reservoir profile,Oil-Water Interface of Fu-yang oil bed in Sanzhao area are not unified in different geological structures and areas. which assume wavy variation,multiple series and structural units combination of oil-gas-water. Generally,the oil distribution are pieces-link.But different fault blocks make a great difference in accumulation degree of oil,because of the high or low tectonic, fault development, petrology characteristics and physical property. Generally,oil and gas are enriched in the surroundings of horst blocks and fault zone.
According to the results of this study, multi-dimensional method is applied to carry on the reservoir prediction, and two types favorable area are forecasted. Based researched above, we work out well site disposition principle. At last implementation demands are put forth for future work.
