基于灰色关联度的气井主控因素定量描述

摘要

低渗致密气藏老井稳产一直是气田开发关注的焦点。通过对气井生产动态分析挖掘主控因素，有的放矢地采取相应措施，是老井稳产的重要方法与手段。研究与应用表明，在气井影响因素模型表征描述的基础上，灰色关联分析能够及时、准确、定量化地提取气井生产主要影响因素，弥补人工定性分析的不足，为气井稳产工艺措施实施提供了重要的决策支持与效果预测，具有较好的可行性与有效性，为气田智能开发与管理探索了一种新思路与新方法。%Keeping old wells producing stably in low permeability tight gas reservoirs is the key point for gas oil field devel-opment .Dynamic analysis ,as an important way and method ,which can discover the key factor of gas wells to take appro-priate measures ,has been an important focus of attention .Research and application shows that ,based on the model of de-scribing the characterization of the factors affecting gas producing ,the gray correlation analysis is able to extract timely ,ac-curately and quantitatively the main factors affecting gas production ,compensate the lack of artificial qualitative analysis and provide decision support and forecasting process measures for stable production of well ,so it is feasible and effective ,which has explored a new idea and approach for intelligent development and management of gas field .
