Embodiment Construction
[0051] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0052] First, a brief description of plugged water gushing patterns in conventional reinjection wells. Such as figure 1 As shown, during the well construction process, especially when the concrete water blocking layer 1 is applied, the concrete needs to be vibrated and compacted. Under the action of uneven or asymmetric vibration loads, the well pipe 2 is prone to sideways the tilt. On the one hand, since the clay ball water-resisting layer 3 is essentially a layer of cohesive soil with fine particles, its plasticity makes it have a certain shape before the well pipe 2 is not inclined, and after the well pipe 2 is inclined, when the water-resisting layer Before the medium clay balls have time to deform in the future, the uncured cement slur...
