气测录井环形网状解释图板及评价方法

The round reticular interpretation chart and evaluation method for gas logging

常规气测录井解释方法均以单点气体检测分析数据为数据源,对单层连续数据的变化分析只能通过逐一绘制出单层中每个点的图板来进行,气测参数在单层中的变化情况既不直观也不规则,且参与解释评价的气体参数有局限性。为解决这一问题,借助Microsoft office软件中的Excel的"图表向导"工具"雷达图",创建了气测录井环形网状解释图板。作为气测录井解释评价的一种新方法,该方法尝试以特定地区的油气显示气测录井数据为统计分析依据,将多个连续的气体参数或比值通过环形网状结构集合到一个图板上,进而根据气体参数在图板上的变化规律确定储集层的流体性质。该方法的创建不仅为气测录井解释评价提供了一种全新的方法,而且对于其他录井技术解释评价方法研究提供了一种新思路。

The conventional gas logging interpretation method generally takes one single point of gas detection and analysis data as data source,the analysis of the continuous data vari- ations in a single layer is only made by drawing the chart corresponding to each point of the single layer one by one. The variation of gas logging parameters in the layer is nei- ther visual nor regular,and the gas parameters concerned in interpretation and evaluation have specified restriction.In order to solve the problem,the round reticular interpreta tion chart for gas logging has been set up with the aid of Radar Map of Excel Tool Chart Guide in Microsoft office software.As a new gas logging interpretation and evalua- tion method,it tries to take oil and gas show data of gas logging for a specific area as a basis for statistical analysis and makes the multi-continuous data parameters or ratios together into one chart through the round reticular struc- ture.And then the reservoir fluid property is determined according to the change rules of gas parameters on the chart.The establishment of this method not only provides a completely new method for gas logging,but also provides a new idea for the other mud logging technique interpretation and evaluation.
