摘要

摘要: 长岭断陷火山岩厚度大,岩石类型多,相态类型齐全,储层发育。火山岩储层不受埋深限制,在深断陷具有良好储集能力,高孔低渗、低孔高渗特色明显;储集空间类型以气孔、溶蚀孔隙及与裂缝的组合为主,裂缝的存在改善了储层的渗流能力;储层类型以双孔双渗为主,少数具有似均质渗流等特征。火山岩优质储层的形成受多重因素控制,有利相带是火山岩储层发育的基础,构造运动是储层形成的关键,风化淋滤及溶解作用是优质储层形成的重要条件。发育在断裂带附近构造高部位的火山机构成藏条件较为有利。

Abstract: In the Changling Fault Depression,volcanic rock formation is very thick.There are various types and facies of rock.Reservoirs are well-developed.The storage capacity of volcanic reservoir is not restricted by burial depth.It is favorable for reservoir in deep fault depression,characterized by high porosity and low permeability or low porosity and high permeability.Reservoir space is mainly composed of bubble pore,solution pore,fissure and their combination.Fissures improve the seepage ability of reservoir."Double porosities and double permeabilities" is the main reservoir type.Some reservoirs have homogeneous porosity and permeability.The formation of good volcanic reservoir is controlled by multiple factors.Favorable facies belt is the foundation.Tectonic movement is the key.Weathering leaching and dissolving also play important roles.The volcanic reservoirs near to the high position of tectonic fault are favorable for accumulation.
