摘　　要：利用油田开发以来的地层测试和生产中的压力恢复曲线资料,表征和评价了近源、陡岸、快速沉积的冲积扇储层物性在断块间、平面、油组间的分布规律,主要受沉积微相控制,岩性边界达到测试井数的39.7％,除极个别井在断层附近有双重介质外,绝大多数反映出储层类型是均一介质,多层反映不明显。将储层按井划分为特高渗透、高渗透、低渗透和特低渗透等四级,其中以特低渗透为主体,占测试井数的56.6％;断块内部的断层多,构造复杂破碎。此研究为改善开发效果提供了依据。The paper makes use of geologic strata test and pressure instauration curve data since the oil-field has been developed to token and evaluate the distributing regulation of reservoir nature in different fault blocks、planes and different oil-bearing groups at the near source、steeply shore and speediness sedimentary alluvial apron, which limited mini-sedimentary faces and rock boundary. The limited occupy 39.7 percent of the total testing well number.Except for particular wells near faults contain dual medium,most of them show that the reservoir is uniform and multi-layers is not obvious. According to reservoir nature, four grades, which are the higher permeation, high permeation,low permeation and lower permeation etc,have been divided and the lower permeate primarily is priority which accounts for 56.6 percent of testing well number among the tested wells. The defaults appear more in the fault blocks internally and the conformation is complicated and broken up. These researches offer a reference for improving the oil-field development.
