摘要
Based on the foundation of the observation of rock cores and cast slice, the macro and micro characteristics of the reservoir of Lucaogou Formation source rock oil in the Malang sag are studied in this paper combining with many methods of experimental analysis. The survey region is rich in lamina.The slippage between layers and broken cracks in laminite formed the important basis of reservoir space. As a high-quality hydrocarbon source rocks,the hydrocarbon generated in laminite can concentrate in reservoir space after an extremely short of primary migration, which is beneficial to the concentration of oil source rocks. Large mounts of nanometer to micron level micro pores and micro cracks develop in the source rock oil reservoir of Lucaogou Formation and their sizes are basically bigger than the diameter of liquid hydrocarbon molecules, so they could form effective reservoir space.
