系国家“八五”科技攻关项目“中国生物气成藏条件及有利勘探区研究”之四级课题,编号85-102-02-04。杭州石油地质研究所承担研究,研究人数6人,课题长严经芳。1992年4月签订研究合同,研究期限两年,完成时间1994的6月。目的通过剖析浙江第四系生物气的分布和典型气藏,总结浙江沿海地区生物气的成藏条件与富集规律,并进行有利探区的生物气勘探目标优选和浅层地震方法试验,为浙江沿海第四系气藏勘探提供理论指导和勘探目标。背景研究期间,共钻各类浅探井848□,采集浅层地震测线93km,化探试验面积25.5km~2,电法(磁偶源探测)试验2.lkm。初步摸索出一套普查勘探方法,以及钻、采、完井技术和集输工艺,达到了降低成本、提高效益的目标。
Department of national “85 ” scientific and technological project “China biogas accumulation conditions and favorable exploration area research ” of the four issues, number 85-102-02-04. Hangzhou Institute of Petroleum Geology commitment to research, the number of 6 people, the subject Yan Chang Jing. In April 1992 signed a research contract, the study period of two years, the completion of time in June 1994. Objective By analyzing the distribution and typical gas reservoirs of Quaternary biogas in Zhejiang Province, the accumulation conditions and enrichment rules of biogas in the coastal area of Zhejiang Province are summarized, and the targets of biogas exploration and the shallow seismic methods in the favorable exploration area are tested. Quaternary reservoirs in Zhejiang coastal area provide theoretical guidance and exploration targets. During the background study, a total of 848 Shallow exploration wells were drilled to collect 93km of shallow seismic lines, 25.5km ~ 2 of geochemical exploration areas and 2.lkm of electrical method (magnetic dipole source detection). Preliminary exploration of a set of census and exploration methods, as well as drilling, mining, completion technology and gathering process, reaching the goal of reducing costs and improving efficiency.
