摘　　要：迪那2气田具有储层物性较差、非均质性强、气水关系复杂以及气水过渡带较厚等特点,采用常规测井解释难以识别这种低渗气藏的气水过渡带。为此,采用毛细管压力曲线结合相渗曲线的方法研究迪那2气田气水过渡带分布特征,得到气田东部苏维依组三段气水过渡带厚度160 m、西部苏维依组三段气水过渡带厚度180 m以及中部白垩系气水过渡带厚度266 m的统计结果并依此建立起气藏气水分布模式。实际测试结果证明此方法建立的气水分布模式是符合实际的,为制定下一步防水、控水措施提供了依据。Dina 2 gasfield,in which most reservoirs are char-acterized by poor petrophysical property and strong heterogene-ity,is typical of complex gas-water correlation and thicker gas-water transitional zones.It is difficult to identify the tran-sitional zones for these low-permeability gas reservoirs by con-ventional well-logging interpretation.So,the distribution attri-butes in these zones were analyzed through two approaches of capillary-pressure curve and relative-permeability curve.Re-sults show that for these gas-water transitional zones,their thickness is respectively 160 m in Palaeogene Suweiyi 3 Mem-ber of eastern field,180 m in western field,and 266 m in Cretaceous.And a gas-water distribution mode was also devel-oped,which not only accords with actual testing result but al-so provides evidence for making water prevention and control measures.
