摘要
由于任丘潜山油藏目前已进入中后期开发阶段 ,单井产量低 ,含水率高 ,老井措施增油难度大。为了控水、增油和稳产 ,通过对油藏动态和静态资料的综合研究 ,结合测井资料剩余油解释和三维地震对潜山形态的精细描述 ,分析了潜山剩余油分布的控制因素 ,比较准确的预测出了受潜山几何形态控制的五种剩余油分布类型 ,为调整挖潜提供了可靠的地质依据 ,在此基础上完钻的 40口调整井的钻井成功率达到 92 .5 %。在保持任丘潜山油藏稳产中 ,地质、测井和地震的综合研究发挥着举足轻重的作用。
Having entered middle-late development stage, Renqiu buried hill reservoir is facing low single-well production, high water cut and difficulties in old-well stimulation. In order to stabilize the oil production by control water, synthetic study of dynamic and static data of reservoir, log interpretation of remaining oil and fine three dimensional seismic descriptions to buried hill's configuration have been done. The factors that control the remaining oil distribution are also analyzed. Five distribution types remaining oil controlled by the geometric shape of buried hill has been predicted accurately, which provided reliable geologic basis for tapping the potentials of the reservoir and played an much important role in production stability in oil field. Forty adjustment wells have been completed, among them is 92.5% successful.
