摘要
三角形图版法是通过气测比值参数评价油气层的传统方法之一。本文运用直线方程法得出了三角形图版法中所成内三角形顶点坐标、价值点坐标的通用表达式,通过坐标计算内三角形与坐标三角形边长比以及内三角形正倒情况,使三角形图版法可以通过excel批量统计成图,改进了过去单个深度点统计的方法。
Gas logging is mainly used to judge formation fluid properties by measuring hydrocarbon composition and content in drilling fluid,which is the main basis for reservoir evaluation while drilling.Triangle chart method is one of the traditional way of evaluating oil and gas layer by gas ratio parameters.In this paper,the general expressions of coordinates of the formed triangle vertexes and value point are obtained by applying the method of linear equation.By these coordinates,the side ratio of coordinate triangle to formed triangle can be calculated and whether it is a regular or an inverted triangle can be judged.It makes the bulk statistical graph of the triangle chart method can be realized in excel instead of the past statistics method per a single depth point,which is more advantageous to make accurate and integrated judge of hydrocarbon reservoir for the same or different.It has improved the efficiency of the application of triangle chart method and sped up the pace of the triangle chart from the qualitative evaluation into quantitative evaluation.
