Directional well of control environment influence

控制环境影响的定向井

Abstract

The utility model relates to a directional well of control environment influence, include from last well casing, chimney filter, the sediment tube that concatenates in proper order extremely down to and U type orientation obstructs device, its characterized in that: U type orientation obstruct the device setting in the chimney filter section, the chimney filter obstructs the U type intra -annular of device in U type orientation, and chimney filter lateral surface and U type orientation obstruct interior bottom surface tangent connection placed in the middle of the U type ring of device. The utility model provides a pair of directional well of control environment influence enables the chimney filter orientation and collects (or zhu ruing) rivers, increases and streams the route, reaches control precipitation or the purpose of control environment influence when recharging, and the efficiency that can improve precipitation or recharge.
本实用新型涉及一种控制环境影响的定向井,包括从上至下依次串接的井管、滤管、沉淀管,以及U型定向阻扰装置,其特征在于:所述的U型定向阻扰装置设置在滤管段,所述滤管在U型定向阻扰装置的U型环内,且滤管外侧面与U型定向阻扰装置的U型环的内底面居中相切连接。本实用新型提供的一种控制环境影响的定向井,能使滤管定向汇集(或注入)水流,增加绕流路径,达到控制降水或回灌时控制环境影响的目的,且可提高降水或回灌的效能。
