摘要：通过对隆鄂尼地区油砂的孔隙度及含油率进行统计，研究了隆鄂尼地区油砂地质特征。研究发现，研究区为低孔超低渗储层，与国内典型油砂矿相比含油率较高、油气保存条件好，是油砂勘探开发有利区域。选取12 件隆鄂尼地区LK-5井的油砂样品进行色谱一质谱分析，进一步了解研究区地化特征。实验结果表明：隆鄂尼地区油砂受到微生物降解，降解程度属1级；油砂与源岩母质类型相关性好，母质来源于海相有机质，母质类型属混合源，且高等植物的贡献较大：油砂样品的有机质沉积环境为威水还原海相环境；油砂油达到成熟阶段。研究成果为隆鄂尼地区油砂资源评价提供了科学依据。

Abstract: With the help of the statistics of the porosities and oil-bearing rates of the oil sands in Long'eni area, the geological characteristics of Long'eni oil sands were studied. The study achievements discover that for the study areas with low porosity and extra low permeability reservoirs, comparing with the domestic typical oil sands, the rates are pretty higher, and the preserving conditions of the oil and gas are also much better, thus the areas become much favorable regions for the oil-sand exploration and development. Twelve oil sand samples from Well LK-5 in Long'eni area were selected for the gas chromatography-mass spectrometry analyses, and the geochemical character-istics of the study area were further understood. The experimental results show that the oil sands in this region have been biodegraded and the degraded degree belongs to Level I ; there are much better correlation between the
