摘　　要：中马格达雷纳盆地是哥伦比亚重要的产油气盆地之一,具有较大开发潜力。本文系统分析中马格达雷纳盆地演化过程、构造和石油地质特征,以及La Luna组烃源岩特征、储层特征、裂缝发育特征和流体特征。研究表明:中马格达雷纳盆地La Luna组具有分布面积广、厚度大、烃源岩品质优、储层物性好等特点,烃源岩成熟度低-成熟、以油为主,油藏压力高,属于典型的非常规油气层。La Luna组为海陆棚沉积环境,含大量生物介壳,储层发育大量微孔隙,矿物成分以方解石/白云石、石英为主,黏土含量低,有利于压裂,且由于方解石/白云石含量高,有利于进行酸化改造措施,受构造作用影响,La Luna组裂缝发育,极大地改善储层渗透性。总体而言,中马格达雷纳盆地La Luna组具有巨大的非常规油气资源潜力和勘探开发前景,但受政策、环保及当地作业环境的影响,难以在短期内实现大规模商业开发。The Middle Magdalena Basin is one of the important oil and gas producing basins in Colombia and has great development potential.This paper systematically analyzes the evolution process, structural and petroleum geological characteristics of the Middle Magdalena Basin, as well as the source rock characteristics, reservoir characteristics, fracture development characteristics and fluid characteristics of La Luna Formation.The research show that the La Luna Formation in the Middle Magdalena Basin has the characteristics of wide distribution area, large thickness, excellent source rock quality and good reservoir physical properties.The source rock is low mature, dominated by oil and high reservoir pressure.It belongs to a typical unconventional oil and gas reservoir.La Luna Formation is a marine shelf sedimentary environment, containing a large number of biological shells, with a large number of micro pores developed in the reservoir.The mineral composition is mainly calcite/dolomite and quartz, and the clay content is low, which is conducive to fracturing.Moreover, due to the high content of calcite/dolomite, and it is conducive to acidizing transformation measures.Affected by tectonic action, the fractures of La Luna Formation are developed, which greatly improves the permeability of the reservoir.Generally speaking, the La Luna Formation in the Middle Magdalena Basin has great unconventional oil and gas resource potential and exploration and development prospects, but it is difficult to realize large-scale commercial development in the short term due to the influence of policies, environmental protection and local operating environment.
