摘要
在豫东地区新近系地层成井,传统的投粒成井工艺和新兴的不投粒成井工艺都在应用。本文通过对区域内位置相邻、深度相近、井身结构相似、取水层位相似的多口水井的出水量进行了对比,通过对地层因素、钻孔直径、洗井方法以及成井工艺因素进行分析,找出在特定条件下影响出水量的主要原因。为不同区域选择合适的成井工艺提供参考。
In the Neogene formation of eastern Henan Province,the traditional and emerging non‑granulation well forming process are being applied.In this paper,by comparing the water output of multiple wells with adjacent positions,similar depth,similar well structure and similar water intake layer level in the region,and analyzing the formation factors,drilling diameter,well washing method and well formation process factors,the main reasons affecting the water volume under specific conditions are found out.It provides a reference for selecting a suitable well‑forming process in different regions.
