摘　　要：通过成像测井解释模式的建立,确定了不同地质现象的成像测井影像响应模式,通过裂缝间的相互切割关系确定了裂缝的发育期次。研究表明辽河坳陷大民屯凹陷西侧元古界主要存在三期构造裂缝:北东向裂缝为第一期裂缝,北东东向为第二期裂缝,近东西向裂缝为第三期裂缝。该研究结果得到岩心测试资料的证实,在此基础上,通过不同走向裂缝段的产能对比,确定了研究区的主要控油裂缝走向为北东向。裂缝期次、产状、主要控油裂缝的确定对于后继的勘探开发意义重大。In this paper,the imaging logging interpretation model is set to define the imaging logging response mode under different geologic phenomena,the interaction cutting relation within the cracks determines the development stage of cracks.Research shows that there are three main stages in the Proterozoic tectonic fractures in Damintun in Liaohe depression:north East fracture as the first stage of crack,northeast east as second crack,east west fractures into third crack.The findings are proved through the core test data.Based on this,comparing production capacity of different crack section,the main fractures in the study area is determined as the North east.The determination of fracture stage,occurrence and main oil control crack is of great significance for subsequent exploration and development.
