摘　　要：利用测试资料,将利津地区深层沙三、沙四段油藏分为5种油藏类型:①高压、低极低渗、导数曲线后期上翘、地层存在非均质性的油藏;②高压、低渗、无污染、双孔介质的油藏;③高压、低中渗、无轻微污染的复合油藏;④常高压、低渗、有污染的油藏;⑤常高压、极低渗、无污染、干层的油藏。最后对利津地区深层沙三、沙四段各种类型油藏进行了评价,认为利津地区深层沙三、沙四段自然产能较低,一般需要进行改造措施来提高渗透性,提高产能。The reservoirs of Es_ 3-4 in Lijin deep strata are divided into 5 types, such as: ①the reservoirs with high pressure and low-extra-low permeability, upwarping with heterogeneity in the reservoir at the late period of derivative; ②the reservoirs with high pressure, low permeability without pollution and with dual porous media; ③composited reservoirs with high pressure, low-mid permeability and non-pollution-slight pollution; ④polluted reservoirs with normal-high pressure, low permeability and pollution; ⑤reservoirs with normal-high pressure, extremely low permeability, without pollution and with dry layers. The reservoirs of each type in Es_ 3-4 in Lijin are evaluated. It is considered that in Es_ 3-4 , reservoirs are of low natural productivity, where stimulation is needed for improving the permeability, raising the production.
