摘要： 二连盆地属 于中生代陆相断陷群,各凹陷发育多种类型的沉积体,特别是扇三角洲和水下扇沉积体普遍发育于凹陷陡带,具备形成岩性油藏的诸多有利条件。巴音都兰凹陷宝力格油藏是一个典型的高位体系域扇三角洲砂岩岩性油藏。应用层序地层学方法和地质综合分析,剖析了宝力格地区扇三角洲砂岩岩性油藏的成藏条件,构建了该区高位体系域扇三角洲岩性油藏的地质模型,阐述了扇三角洲砂体形态的地震信息识别和含油性预测的新方法,介绍了勘探应用效果。

Abstract: Erlian basin belongs to a Mesozoic continental fault group, in which various types of sedimentary bodies could all be found, especial-ly the fan delta and underwater fan sedimentary bodies occured in steep-sided sections of sags. Hence, it has favorable conditions for forming lithologic oil reservoirs. Baolige reservoir in Bayindulan sag is a sandstone lithologic reservoir in fan delta with typical highstand system tract. This paper analyzes the hydrocarbon accumulation conditions in fan delta lithologic sandstone lithologic reservoir area by means of sequence stratigraphy and geology, and develops the geologic model for fan delta lithologic reservoir with highstand system tract in Baolige area. Also, this paper presents some new methods for recognition of seismic information about the fan delta sandbody configuration and prediction of petrolifer-ous features, and finally introduces applied results for its petroleum exploration.

Key words: Erlian basin, geologic model, lithologic reservoir, fan, dela, recognition
