摘要
在录井分析技术中,利用饱和烃气相色谱来评价含油岩样的含水性,并手动绘制光滑外凸闭合曲线以确定含油岩样的含水性指数。人工绘制图版工作量较大,需要大量人力物力,而且误差较大,因此有必要开发相应的软件以提高效率。以录井分析技术的实践经验为基础,将实际困难和需求进行理论分析,利用凸壳、三次B样条曲线以及插值等算法从理论上提出解决方案,并开发基于C#语言编程计算饱和烃气相色谱含水性评价指数的软件系统。节约人力资源并提高含水性评价指数的精确性。
In logging analysis, the gas chromatogram of saturated hydrocarbon is used to evaluate the aquosity of oil rock sample. And a slippy, convex and closed curve is drawn manually to determine the water proportion of oil rock sample. It needs larger workload to draw plates manually, and it has larger error. So it is necessary to develop a software to improve efficiency. To logging analysis based on practical experience, theory is analyzed and verified from practical difficulties and needs. The solution is proposed theoretically by using some algorithms like convex hull algorithm and cubic b-spline curve. A software is developed to calculate the water proportion based on C# programming language. It saves human resources and improves the water proportion precision.
