| 摘 要： | 以破碎单位体积岩石PDC微钻头的磨损量作为岩石研磨性指标,以南海西部7个油田的岩心作为实验样本,测定了石油钻井中常见沉积岩的研磨性.根据实验结果确定了岩石研磨性与岩石硬度、内摩擦角存在幂函数关系,建立了通用地层研磨性预测模型,并借鉴现场经验及前人分级方案提出了钻井工程岩石研磨性分级参考标准.利用本文提出的通用模型建立了... |

| Abstract: | We use the cores from seven oilfields in Western South China Sea as the experiment samples and take the weight loss of micro PDC bit for breaking unit volume of rock as the indicator to determine abrasivity of common sedimentary rocks encountered in drilling.According to the experiment results,we determine the power function relation among the rock abrasivity,hardness and internal friction angle,establish a universal prediction model and propose a reference standard for rock abrasivity classification in dri... |
| Keywords: | formation abrasivity PDC bit prediction model reference standard for rock abrasivity classification |
