Abstract

Abstract: The data of core description and survey of field fractures were used to investigate the systems and altitude, property, development degree and control factors of fractures in the low-permeability and low-porosity reservoirs of Chaiwopu anticline structure in Junggar Basin. The tectonic fractures in this area are mainly the high-angle shear fractures and include three groups of fractures extending in the north-west direction from 310ºto 330º, east-west direction from 270ºto 280ºand north-east direction from 40ºto 60ºand also include a group of conjugated shear fractures mainly centralized in north-west and east-west directions. The development and distribution of the tectonic fractures are controlled by regional tectonic stress, folding, lithologic characteristics and rock thickness.

Key words: Junggar Basin, Chaiwopu Sag, anticline structure, reservoir fracture, control factor

摘要： 应用岩心裂缝描述和野外露头区裂缝调查资料,对准噶尔盆地柴窝堡凹陷柴窝堡背斜低孔隙低渗透性储层构造裂缝的组系与产状、裂缝的性质、裂缝的发育程度及其控制因素进行了分析研究。结果表明,柴窝堡背斜储层主要发育有4组构造裂缝,分别为NW向(310º~330º)、近EW向(270º~280º)和NE向(40º~60º)的3组裂缝以及NW向(320º±10º)和NWW向(280º±10º)的1组共轭剪切裂缝。其中以NW向和近EW向裂缝为主,这些裂缝中又以高角度的剪切裂缝为主。裂缝的发育和分布受控于构造应力、褶皱、断层、岩相(岩性)及岩层厚度等因素。
