EFFECT OF INJECTING WATER DEVELOPMENT ON MICROSTRUCTURE OF RESERVOIRS IN GUDAO OILFIELD

摘要: 该文在岩石薄片、铸体薄片、扫描电镜、物性及压汞等资料分析的基础上,对孤岛油田不同开发时期储层的岩性、物性、孔隙结构和含油性等进行了全面分析研究.研究表明,长期注水开发提高了储层的物性,改善了孔隙结构,降低了泥质含量和束缚水饱和度,一定程度地改善了储层微观结构.

Abstract: On the basis of information of rock sections,cast sections,ESM and mercury injection curves etc.,a systematic study on the characteristics of microstructure of reservoirs in the Guantao Formation of Gudao oilfiele during different development periods was given.The results show that the microstructure has been improved by water-injecting development.
