摘要
三塘湖盆地经过几年的勘探,先后在马朗凹陷发现了牛圈湖、马中、黑墩油田。由于二叠系芦草沟组储层复杂,油气的聚集严格受裂缝控制,目前欠缺提高自然产能有效的手段,使盆地的勘探陷入被动局面。从岩心资料出发,结合地震及测井资料,对马朗凹陷芦草沟组裂缝的形成时间、规模、充填状况、含油气性做了精细描述,总结归纳了裂缝在测井资料上的响应特征,在此基础上对马朗凹陷芦草沟组裂缝在纵、横向的分布特点进行了总结。
After several years of exploration, Niujuanhu, Mazhong and Heidun reservoir have been discovered consecutively in Malang sag. Since the reservoirs of Permian Lucaogou formation are very complex, and the accumulation of oil and gas is rigorously dominated by fractures, as well as there is deficient in ways currently to improve natural productivity, the exploration in the basin is thrown into passivity. In this paper, the generation stage, scale, fill and hydrocarbon potential of fractures in Lucaogou formation, Malang sag are described in detail integrated core data , seismic and logging data. On this basis, the lateral and vertical distribution characteristics of fractures in Lucaogou formation, Malang sag are summed up.
