Method of making cased bore hole, cased bore hole per se and sevice casing column for bore hole cementing

摘要

Paženého way to create a borehole comprising the steps of drilling a borehole (4) of a desired depth and technological arrangement of the casing column (5) comprising mutually coupled plastic tubes in the bore hole (4). The casing column (5) comprising a filter zone (2) and full zone (3) located above the filtration zone (2). At least two adjacent tubes of the casing column (5) are mutually connected by welding a welding apparatus (15) and counter-pressure on the inner wall at least a portion of the casing column (5) against the external pressure by feeding a cementing mixture is formed so that this portion of the casing column (5 ) Bring non-pressurized clogging liquid mixture. Sheeting borehole contains casing column (5) comprising mutually coupled plastic tubes, at least two neighboring trubkyjsou mutually coupled electro (15). The casing column (5) for cementing a borehole comprising mutually coupled plastic tubes established in the bore hole (4) and the filtration zone (2) and full zone (3). The casing column (5) contains a column of a non-pressurized clogging liquid mixture in at least part of the casing column (5).
