摘要： 焉耆盆地本布图东地区油气层集中分布在下侏罗统三工河组下段和八道湾组上段。在油组划分和对比基础上,研究了Ⅰ-Ⅳ油组的岩性及物性特征; 应用测井约束地震反演方法,预测了其厚度与物性的横向变化,在三维空间描述了油组分布规律。研究结果表明,该区含油气储集层具有分选性差、泥岩含量低、物性差的特征,属于低孔– 特低渗型储集层。油组砂体在构造高部位较厚、物性较好,向低部位减薄变差,图 301 井东南区是有利储集层发育区。

Abstract: The reservoirs of east Benbutu area are mainly distributed in the lower member of Sangonghe formation and the upper member of Badaowan formation of Lower Jurassic in Yanqi basin.Based on the payzone division and correlation, the lithologic and physical characteristics of the Ⅰ-Ⅳ payzones are studied.The lateral changes of payzone thickness and physical characters in the reservoirs are predicted with logging constrained seismic inversion, and the payzone distribution of 3D is described.The result shows that there exist the features of poor sorting, low shale content and poor physical properties in the reservoirs, which belong to low-porosity and extra-low permeability reservoirs.The payzone sands are thicker in the structural high and better in physical property, but become thin and poor towards the structural low.It is concluded that the southeastern Wellblock Tu-301 is well-developed reservoir rock area and favorable for further petroleum exploration.

Key words: Yanqi basin, Jurassic, reservoir, seismic inversion, prediction
