渤海油田渤中13-1南区块馆陶组储集层流体性质识别方法研究
|
摘要
为了解决渤海油田渤中13-1南区块油质复杂、流体类型识别难度大的问题,通过统计气测资料、测井资料和试油资料,对该区块馆陶组不同流体类型气测组分及其派生参数和荧光显示特征进行了研究,建立了馆陶组气测-荧光解释评价标准,同时利用地化参数及其派生参数建立了地化亮点图板。应用气测-荧光解释评价标准与地化亮点图板相结合,对目前已钻预探井进行解释评价,结果表明,解释层数82层,其中74层符合,解释符合率为90.2%,对该区块新钻井进行现场综合解释,解释14层,其中12层符合,综合解释符合率达到85.7%。该方法大幅提高了现场解释符合率,为下一步勘探开发决策提供了有利依据。
In order to solve the problem of complex oiliness and difficulty in identifying fluid types in Bozhong 13-1 south block of Bohai Oilfield,gas logging components,derived parameters and fluorescence display characteristics of different fluid types in Guantao formation of this block were studied by means of statistical gas logging data,log information and potential test data.The interpretation and evaluation criteria for gas logging and fluorescence of Guantao formation were established.At the same time,geochemical bright spot chart was established by using geochemical parameters and their derived parameters.Combing interpretation and evaluation criteria of gas logging and fluorescence with geochemical bright spot chart,the results of interpretation and evaluation of the present drilled exploration wells showed that the number of interpretating layers was 82 layers and 74 layers coincided with potential test,the coincidence rate of interpretation was 90.2%.The field comprehensive interpretation of new wells in this block was carried out,14 layers were interpreted,of which 12 layers coincided with potential test,and the comprehensive interpretation coincidence rate was 85.7%.This method greatly improves the coincidence rate of field interpretation and provides a feasible basis for further exploration and development decision-making.
