对南盘江地区进行野外石油地质考察,在中三叠统法郎组中发现液态油苗.该油苗位于云南省泸西地区,地表延伸长度超过12km.舍油层位的岩性为全黑色生物碎屑泥晶灰岩,油气显示性质为液态油苗和稠油,呈褐黑色、褐黄色,多以浸染状、晶间孔型、溶洞型和裂缝型产出.舍油层的下伏地层为中三叠统个旧组,主要为一套碳酸盐岩沉积,产2套累计厚度16m左右的油浸砂糖状白云岩.舍油层上覆地层法郎组上段为一套泥质碎屑岩沉积,该套地层的泥岩段中有大量油斑产出.液态油苗的发现显示了该区良好的油气勘探前景.

During the field investigation of petroleum geology in the Nanpanjiang area of the southeastern Yunnan Province.China,liquid oil seepage in the Middle Triassic, Falang Formation was firstly discovered in Luxi County. The oil seepage extends to morebrown-black or brown -yellow liquid and heavy oil seepage, and occurs as impregnation, intercrystalline pores, dissolved caverns andfissures. The underlying strata of the oil-bearing strata are the Middle Triassic, Gejiu Formation, which is a set of marine carbonaterock. Two sets of saccharoidal oil-immersed dolomites in a total thickness of 16m was found. The upper Falang Formation coveringthe oil-bearing strata is a set of clay clastic rock displaying a lot of oil spots. All these discoveries indicate good prospects for oil and gasexploration.
