四川盆地威远地区五峰组—龙马溪组页岩TOC含量地震定量预测方法及应用
|
摘要
四川盆地威远地区内部钻井少,仅靠岩心实测和测井计算的TOC含量评价该区页岩气资源潜力难度较大,利用地震资料预测页岩TOC含量不但能弥补该区钻井取心少的不足,而且能够评价无井地区页岩的TOC含量。以四川盆地威远地区W201井区三维五峰组—龙马溪组一段1亚段为例,利用钻测井及三维地震资料定量预测了页岩TOC含量的平面及空间分布。首先通过测井计算得到的TOC与地球物理参数交会分析,优选出敏感参数密度,在此基础上,分析该区钻井岩心实测和测井计算的TOC含量与密度的关系,得到计算TOC含量的地震预测模型,然后利用叠前同时反演技术获得该区的密度体,通过预测模型最终实现页岩TOC含量的定量预测。结果表明:①地震预测的TOC与岩心实测和测井计算TOC结果较为吻合,误差较小;②研究区东南部及北部W201井区TOC含量较高,平均值可达2%～4%,为勘探开发有利区。结论认为,该TOC定量预测方法对于研究区适用有效,且对川南地区页岩气勘探开发评价具有一定的指导意义。
There is less internal drilling in the Weiyuan area of the Sichuan Basin.It is difficult to evaluate the shale gas resource potential in the area by the TOCcontent of the core measurement and logging calculation.Using seismic data to predict shale TOCcontent can not only make up for the lack of drilling cores,but also can evaluate the TOCcontent of shale in well-free areas.Taking the 1st section of the Wufeng Formation-Longmaxi Formation in the Weiyuan area of the Sichuan Basin as an example,the plane and spatial distribution of shale TOC content were quantitatively predicted by drilling logging and 3 Dseismic data.Firstly,the TOCand geophysical parameters obtained by logging calculation are analyzed,and the density of sensitive parameters is optimized.On the basis of this,the relationship between the TOCcontent and the density of the core measurement and logging calculation of the vertical well in the area is analyzed,and the TOCcontent is calculated by seismic prediction model.Then,the density of the area is obtained by prestack simultaneous inversion technique,and the quantitative prediction of shale TOCis finally realized by the prediction model.The results show that:(1)The TOC of seismic prediction is in good agreement with the core measurement and log calculation TOCresults,and the error is small.(2)The TOCin the southeastern part of the study area and the Well W210 area in the north is higher,with an average value of 2%-4%,which is a favorable area for exploration and development.It is concluded that the TOC quantitative prediction method is effective for the study area and has certain reference significance for the evaluation of shale gas exploration and development in southern Sichuan.
