摘　　要：李国平，石强，王树寅．储盖组合测井解释方法研究．测井技术，１９９７，２１（２）：９８～１０４根据油气藏成藏理论，油气藏形成之后，上覆盖层质量的变化会严重影响油气的聚集。大量事实证明，一些钻孔显示很好的层段曾经有过油气聚集，但由于后来盖层封闭性能变差，油气大量散失，形成了现今的残余油气藏。因此，测井解释不能仅对储层进行研究，还要对盖层封闭性能进行评价才能准确解释其含油气性。在此基础上提出了储盖组合测井解释观点，并建立了封闭、开启型油气藏测井解释模式。Based on the theory of hydrocarbon accumulation, the changes of overburden quality can seriously affect the hydrocarbon accumulation after the reservoir is formed.A lot of case histories proved that some intervals with good oil show were hydrocarbon accumulation zones before. But because of poor confinment of the caprock, large quantity of hydrocarbon escaped, which results in residual reservoirs. Therefore, in order to enhance the accuracy of log interpretation, not only the reservoir but also the confining properties of caprock must be evaluated. A new reservoir caprock composite log interpretation method is proposed and log interpretation models are set up for confined and open reservoirs.
