摘要/Abstract

摘要： 定量预测致密岩石中矿物组分含量和脆性特征，可以为非常规油气勘探目标和压裂井段等的优选提供依据。以中国西部地区ZKZ盆地侏罗系含煤地层和YBL盆地侏罗系非含煤地层为例，利用常规测井资料和岩心分析数据，优选对矿物组分较为敏感的常规测井曲线。将参与建模的敏感测井曲线进行了标准化处理，用多元回归分析方法，建立了含煤地层和非含煤地层致密岩石中矿物组分含量及脆性特征的定量预测模型，并对含煤地层和非含煤地层致密岩石脆性特征及其成因进行了论证。预测结果与实测值具有较高的一致性。

Abstract: Quantitative prediction of mineral component content and brittleness in tight rocks can provide a basis for optimization of exploration targets and fracturing intervals in unconventional reservoirs. Taking Jurassic coal?bearing strata in ZKZ basin and Jurassic non?coal strata in YBL basin in western China as examples, conventional logging curves sensitive to mineral components are selected based on conventional logging and core analysis data. Standardized processing is performed for sensitive logging curves related to modeling. Based on multivariate regression analysis, a quantitative model is established with multivariate regression analysis to predict mineral component content and brittleness in tight rocks in coal?bearing and non?coal strata, and the features and geneses of tight rock brittleness are demonstrated.The prediction results highly correspond to the actual measured values
