【摘要】 压裂作为油气勘探、开发与开采中的主要手段，在油气井增产方面发挥着重要作用。压裂施工曲线图是压裂施工情况的真实反映，由于压裂施工参数多、数据量大、时间密度大，需要对海量数据进行处理并以曲线的形式展示出来。在分析现有金字塔模型构建思想的基础上，提出一种面向压裂施工曲线的金字塔模型的构建方法，并给出方法的构建过程。采用Douglas-Peucker算法对压裂施工曲线数据进行分层处理，建立不同数据量层次的金字塔模型。实验结果表明，该曲线数据金字塔模型的引入，实现了压裂施工曲线数据高效加载、快速绘制及浏览的性能。更多还原

【Abstract】 As the main means of oil and gas exploration, development and exploitation, fracturing plays an important role in oil and gas well stimulation. The fracturing construction curve was a true reflection of the fracturing construction situation. Due to many fracturing construction parameters, large amount of data and large time density, massive data need to be processed and displayed in the form of curves. Based on the analysis of the existing pyramid model construction ideas, a pyramid model construction method for fracturing construction curve is proposed, and the construction process of the method is given. Douglas-peucker algorithm was used to stratify the fracturing construction curve data, and the pyramid models with different data levels were built. The experimental results show that the introduction of the curve data pyramid model can realize the performance of the fracturing construction curve data loading efficiently, drawing and browsing quickly.更多还原
