| 摘 要： | 为了更准确地研究下生上储组合中断裂发育区油气分布规律，在前人断-砂配置侧向输导油气能力定量研究的基础上，不仅考虑断-砂接触长度和砂体物性对断-砂配置侧向输导油气能力的影响，而且考虑了砂体倾角对断-砂配置侧向输导油气能力的影响，改进了断-砂配置侧向输导油气能力定量研究方法。选取渤海湾盆地南堡凹陷5个典型区块中浅层内12条油源断裂为例，利用改进前、后断-砂配置侧向输导油气能力定量研究方法，对其与16口井中浅层67个砂层配置形成的侧向输导油气能力进行了定量研究。结果表明，改进后方法研究得到的断-砂配置侧向输导油气能力评价参数值与砂体中的油气柱高度之间为正比关系，其值越大，砂体中油气柱越高；反之则越低。当断-砂配置侧向输导油气能力评价参数值大于0.4，油气钻探为油层或同层，小于0.4则为水层或干层，二者吻合关系好，表明改进后方法用于定量研究断-砂配置侧向输导油气能力是可行的。由于改进后方法研究得到的断-砂配置侧向输导油气能力评价参数值明显低于改进前方法得到的断-砂配置侧向输导油气能力评价参数值，表明改进前方法的评价结果可能过高地评估了断-砂配置侧向输导油气能力，给油气勘探带来风险。

| Abstract: | In order to more precisely reveal the hydrocarbon distribution of fault zones in the upper source rock-lower reservoir assemblage,we present an improved method of quantifying the lateral transport capacity of the fault-sandstone configuration,considering both the effect of fault-sandstone contact length and physical property of sand bodies,and the effect of dip angles of sand bodies.Twelve faults in the middle-shallow layers were selected from five typical blocks in Nanpu Sag,Bohai Bay Basin,to quantitatively estimate and compare the lateral transport capacity of the configurations of the 12 faults and 67 sandstone layers in 16 wells by using the original and improved methods,respectively.The results show that:the parameter values obtained by using the improved method correlate positively with the height of oil-gas column in sand bodies,that is,the bigger the values are,the higher the oil-gas column becomes; and vice versa.When the parameter value is over 0.4,the sandstone reservoir contains oil or both oil and gas,while when its value is less than 0.4,the sandstone reservoir contains water or is dry,indicating the applicability of the improved method.The parameter values obtained with the improved method are remarkably lower than that worked out by the original method,indicating an overestimation by the original method and thus resulting in risks to oil-gas exploration. |
