摘要

摘要: 以鄂尔多斯盆地苏里格气田东区的勘探开发资料为基础，根据储层含油气物性下限的定义与特点，运用统计方法与成藏机理方法对东区储层含气物性下限进行了研究。结果表明，2种方法得出的储层含气物性下限值基本接近，盒8段储层含气的孔隙度下限为2.223%，渗透率下限为0.005 7×10^-3μm²；山1段储层含气的孔隙度下限为1.605%，渗透率下限为0.004 4×10^-3μm²，含气物性下限与充注动力负相关，盒8段含气物性下限大于山1段。通过实测资料寻找含气物性下限附近的储层，对连续取样进行含气饱和度测定，分析表明，物性在含气物性下限附近的储层含气饱和度极低，物性高于含气物性下限的储层含气饱和度显著升高。理论分析结果与取心实测结果基本一致。

Abstract: According to the definition and characteristics of the lowest limit for reservoir gas-bearing capacity, we carried out statistical and accumulation mechanism studies in the eastern Sulige gas field in the Ordos Basin. The two methods reached a similar conclusion. The lowest limits for the porosity and permeability of the eighth member of Shihezi Formation (He8) are 2.223% and 0.005 7×10^-3 μm², respectively. The lowest limits for the porosity and permeability of the first member of Shanxi Formation (Shan1) are 1.605% and 0.004 4×10^-3 μm², respectively, which are both higher than those of He8. The lowest limit for reservoir gas-bearing capacity is negatively related to charging force. We collected samples from the reservoirs with physical properties close to the lowest limit, and tested their gas saturation. The gas saturation of the reservoirs with physical properties close to the lowest limit is extremely low, and obviously increases in reservoirs with better physical properties. Theoretical analyses are consistent with coring results.
