摘　　要：腰英台油田是东北地区新发现的油田,目前刚开始勘探开发,在勘探开发初期遇到不少问题,其中之一是开采时高含水。就油田的实际油水分布特征进行了分析,分析油水同出的可能原因,认为这是受油藏储层物性及构造幅度和实际油柱高度的影响,由于储层低孔、特低渗,实际构造幅度低,实际油柱高度大多低于油藏产纯油所需的油柱高度,致使油藏大都处于油水过渡带,故开采时多含水,油水同出。根据这一分析,认为进一步的油气勘探重点考虑西部水下冲积扇的有利部位,此处储层物性好,有利于接受更多油源。Yaoyingtai oilfield was a recently discovered oilfield in the northeast region and its exploration and development were started at present.Some problems occurred druing the early period of exploration and production,one of which is high water content.The distribution features of oil and water,the possible reasons for producing both oil and water are analyzed in the text.It is concluded that the phenomenon of oil and water synchronous is affected by the factors like physical properties of reservoir,structural range and height of actual oil volume,and the porosity and permeability of reservoir are especially low.Through the above analyses,the favorable portions of the western underwater fluvial fan are suggested for further exploration.
