地震属性约束定量预测储层参数——以渤海D油田4号砂体为例
|
摘要
在渤海D油田,储层的非均质性已成为影响钻井成功率的重要因素,因而储层参数的定量预测是一个迫切需要解决的问题。通过已钻井不同储层参数与多种地震属性的交会分析,可以优选出相关度较高的地震属性去量化表达某一储层参数,进而利用两者间的定量关系准确预测出储层的岩性、物性和含油气性参数,实现地震属性约束下的储层参数定量预测,其流程主要包括六个环节:测井资料处理、储层参数计算、地震层位解释、地震属性提取、地震属性优选和储层参数转换。以渤海D油田的4号砂体为例,重点分析了地震属性需要优选的原因和储层参数转换的方法;后期钻井结果证实了储层参数预测结果非常接近于储层实际情况,可以用来对储层进行综合评价。
With the gradual deepening of exploration and development of D oilfield in Bohai,reservoir heterogeneity has become an important factor in affecting the success rate of drilling.Therefore the quantitative prediction of reservoir parameters is a problem which needs to be solved urgently.Through the crossplot analysis of different reservoir parameters with multiple seismic attributes at well points which have been drilling,the seismic attributes with a high correlation can be optimized to express a reservoir parameter quantificationally.Then the quantitative relationship between them can be used to predict the reservoir lithology,physical property and hydrocarbon accurately.Therefore the prediction of reservoir parameters with restraint of seismic attributes can be achieved.The process consists of six main components:logging data processing,calculation of reservoir parameters,seismic horizon interpretation,extraction of seismic attribute,optimization of seismic attribute and conversion of reservoir parameter.Take the number four sand of D Oilfield in Bohai for example,the reason to optimize seismic attribute and the method of converting seismic attributes to reservoir parameters are mainly analyzed.Post-drilling wells confirm that the prediction result of reservoir parameter with the restraint of seismic attributes is very close to the real depth of reservoir.The predicted result can be used to conduct comprehensive evaluation of the reservoir and provide a reliable basis for the implement of development plan and optimization of well locations.
