Freezing cycle recovery process after breakage of long-distance horizontal freezing pipe and annular space filling material
The invention discloses a freezing cycle recovery process after breakage of a long-distance horizontal freezing pipe and an annular space filling material. The annular space filling material is prepared from the following components in parts by weight: 230 to 380 parts of cement, 40 to 250 parts of GF-202, 3 to 195 parts of GF-204 and 700 to 1030 parts of saline water. And the density of the saline water is (1.10-1.30) * 10 < 3 > kg/m < 3 >. According to the process, the annular space filling material is used as a filling medium for filling an annular space of a fractured freezing pipe and a freezing sleeve to perform freezing circulation recovery. The technical problem that the freezing effect is not ideal after circulation is recovered through an existing freezing circulation recovery technology after the freezing pipe is broken can be solved.
本发明公开长距离水平冻结管断裂后冻结循环恢复工艺和环形空间充填材料，环形空间充填材料由如下重量份的各组分组成：230～380重量份的水泥、40～250重量份的GF‑202、3～195重量份的GF‑204和700～1030重量份的盐水；且盐水的密度为(1.10～1.30)×103kg/m3。该工艺是以上述环形空间充填材料作为充填断裂冻结管和冻结套管环形空间的填充介质进行冻结循环恢复工艺。本发明可以解决现有的冻结管断裂后冻结循环恢复工艺恢复循环后冻结效果不理想的技术问题。
