摘要
本文在研究大民屯凹陷大量地质、地震、测井、地化等资料的基础上，应用二维盆地模拟技术，重建了该凹陷的沉积构造发育史、地层热变史，利用地化法、压实法恢复了盆地的生烃史和排烃史，并模拟了各洼陷及全区的油气资源量。模拟结果以单井图、剖面图、平面图及直方图形式输出，达到实用地质图件要求。通过“４史”图件的综合配套分析，评价了３个主要生油凹陷和１０个构造带，其结果与油田勘探实际情况符合；并指出两个新的勘探领域，为新的勘探部署提供了依据。
In this paper, a large amount of geological, seismic, logging as well as geochemical data are gathered, sedimentary and structural evolutional history and thermal alteration history of formations of this sag in geologic history are reconstructed by means of 2-dimensional basin modeling technique. History of hydrocarbon generation and its expelling are restored by means of geochemical and composition technique, and the oil and gas resources in various belts and regions as well as in the whole sag are modeled out. The results are displayed in the form of single well profiles, cross sections, plain maps and histograms matching the requirements of geological maps. With an integration analysis of these data and figures, 3 mainoil generation sags and 10 structural belts are appraised with results highly conformed withactural field exploration and development practices, and 2 new regions are suggested giving abasis for further petroleum exploration.
