摘要
近年来,在油气勘探研究领域中开始研究沉积区火成岩侵入的影响,以及火成岩后期经过复杂的物理化学改造作用后形成大量的溶孔和微裂隙,可作为很好的储油储气空间。鄂尔多斯盆地西南缘龙门地区有岩浆岩体侵入,火成岩岩相主要为火山通道相和喷溢相,岩石类型主要为中、酸性熔岩类火成岩,经后期改造作用,溶孔、微裂隙较为发育。该区的烃源岩,受后期岩浆侵入影响,成熟度较高,生油生气潜力较大,且火成岩经改造作用形成较好的储集空间,为油气成藏提供了有利条件。
In recent years,in the field of oil and gas exploration research,people started studying the affection of invasion of igneous rock in sedimentary zones,and the igneous rock went through complicated physical and chemical modification then formed a large number of dissolved pores and micro-crack which could become very good oil and gas storage space.In the southwest edge of Ordos basin,Longmen area has magmatic rock intrusion,igneous rock facies are mainly the volcano channels and eruption facies,and the rock types are mainly acidic lava and medium of acidic lava igneous rock.After later reconstruction,solution hole and microcracks developed.The hydrocarbon source rock develops in this area and the maturity is higher and the potential of source rock is larger by later magma intrusion effect.The igneous rock role formed good reservoir space after transformation which provides conditions for oil and gas accumulation.
