摘要:
准噶尔盆地车排子凸起东部的石炭系油气资源潜力大,但因岩浆岩储层岩性复杂多变,严重制约着该区油气资源的高效勘探开发。以岩心分析、测井解释、录井资料为研究基础,结合前人石炭系储层相关研究成果,揭示了车排子凸起东部石炭系储层差异性,明确了造成其储层差异性的主控因素。结果表明:研究区石炭系岩性主要有凝灰岩、安山岩、玄武岩、火山角砾岩、沉凝灰岩和凝灰质砂岩等,储层储集空间有原生孔隙、次生孔隙和裂缝三类;因受岩相差异、风化淋滤及构造运动的影响,储层储集性能在纵向及平面上存在明显的非均质性。纵向上石炭系顶部(距顶800 m内)储层物性好,为油气分布的主要储集层,平面上研究区中东部石炭系具有较大的勘探潜力,而其它地区储层物性较差。以上结论对车排子凸起东部的石炭系油气资源的勘探开发具有一定的指导意义。
Abstract:
The carboniferous hydrocarbon resources in the eastern part of Chepaizi Uplift in the Junggar Basin have great potential,but the efficient exploration and development of hydrocarbon resources in this area are severely restricted due to the complex and variable lithology of the magmatic reservoirs. Based on the core analysis,logging interpretation,and logging data,and combined with previous research results on carboniferous reservoirs,the difference of the carboniferous reservoirs in the eastern part of the Chepaizi Uplift was revealed,and the main controlling factors causing the variability of the reservoirs were clarified. The results show that the carboniferous lithologies in the study area mainly include tuffs,andesites,basalts,volcanic breccias,sunken tuffs,tuffaceous sandstones,etc. There are three types of reservoir storage spaces: primary pores,secondary pores,and fractures. Due to the influence of lithofacies difference,weathering leaching,and tectonic movement,there is obvious heterogeneity in the reservoir storage properties in the longitudinal and planar directions. Longitudinally,the upper carboniferous reservoirs (within 800 m from the top) have good reservoir properties and are the main accumulation area for oil and gas distribution. The Carboniferous System in the east-central part of the study area has a large exploration potential in the plane,while the reservoir properties in other areas are poor. The above conclusions have certain guiding significance for the exploration and development of carboniferous oil and gas resources in the eastern part of the Chepaizi Uplift.
