近年来,富县探区延长组发现了多个工业油流井,已发现多个含油富集区,有良好的勘探开发前景。在前人研究基础上,结合研究区勘探开发现状,详细评价研究区基础资料,分析了沉积地层、储层以及油藏类型,参照己完钻井的试油、试采等资料,重点研究长6、长8油藏成藏要素,富县地区的延长组油藏以岩性油藏为主,油层的富集与储层有密切的关系,富县地区主体位于三角洲前缘-前三角洲地带,频繁的湖侵-湖退造成盖层发育,可以形成很好的储盖组合。在探区中部和北部的构造斜坡背景上,近物源端延长组三角洲砂体较为发育,是本区延长组油气有利勘探区,为下一步勘探开发的重点。
In recent years, a number of industrial oil flow wells have been discovered in the Yanchang Formation in the Fuxian Exploration District. Several oil-rich areas have been discovered and have good exploration and development prospects. Based on the previous research, combined with the status quo of exploration and development in the study area, the basic data of the study area are evaluated in detail. The types of sedimentary strata, reservoirs and reservoirs are analyzed. With reference to the test oil production and trial production, , Chang 8 reservoir formation elements, the Yanchang Formation reservoir in Fuxian area is dominated by lithologic reservoirs, and the reservoir enrichment is closely related to reservoirs. The main body of the Fuxian area is located in the delta front-front delta zone, Frequent lake intrusion - lake retreat caused cap development, can form a good reservoir cap combination. On the tectonic slope background in the central and northern part of the exploration area, the sand body near the source extension group is well developed and is the favorable exploration area for the Yanchang Formation in this area, which is the focus of exploration and development in the next step.
