Abstract
The utility model relates to a grouting air exhausting device and belongs to the well drilling mud pouring air exhausting construction technical field. The grouting air exhausting device comprises a grouting pipeline, a connector and an air exhausting pipeline, the upper end of the connector is a blind plate, the lower end of the connector is a thread connected with a well opening sleeved pipe, the grouting pipeline is connected on the blind plate in a welding mode, the air exhausting pipeline is connected with the lateral wall of the connector in a welding mode. The grouting air exhausting device has the advantages that mud grouting and air exhausting can proceed at the same time when the mud is poured into a sleeved pipe under the well, the speed of grouting is fast, thereby avoiding the occurrence of the mud spraying backward phenomenon caused by mud is rebounded upward by the compressed air in the sleeved pipe, so that the environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of grouting exhaust plant, belongs to drilling mud perfusion exhaust technical field of construction.
Background technology
In the casing job, need to be to mud grouting in the down-hole casing, be used for equilibrium strata pressure, prevent from squeezing flat sleeve pipe.Existing grouting method is to be poured into from wellhead casing pipe by mud line, has following defective: the one, and casing job blocked portion phenomenon easily appears in the mud grouting overlong time; The 2nd, when mud grouting, mud is returned spray phenomenon, contaminated environment by the anti-mud that causes on the compressed air in the sleeve pipe.
The utility model content
The purpose of this utility model is in order to overcome in the above-mentioned prior art when the mud grouting, and mud is returned the spray phenomenon by the anti-mud that causes on the compressed air in the sleeve pipe, and the defective of contaminated environment provides a kind of grouting exhaust plant.
The utility model is comprised of grouting pipeline, joint, exhaust line, and upper end of joint is blind plate, and the lower end is the screw thread that is connected with wellhead casing pipe, is welded with the grouting pipeline on the blind plate, is welded with exhaust line on the side pipe wall of joint.
The beneficial effects of the utility model are: when mud grouting in down-hole casing, but limit mud grouting limit exhaust, mud grouting speed is fast, avoids mud by the anti-generation that causes mud to return the spray phenomenon on the compressed air in the sleeve pipe, environmental contamination reduction.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is comprised of grouting pipeline 1, joint 2, and joint 2 upper ends are blind plate, and the lower end is the screw thread that is connected with wellhead casing pipe, is welded with grouting pipeline 1 on the blind plate, is welded with exhaust line 3 on the side pipe wall of joint 2.
The outlet of grouting pipeline 1 is in the bottom of joint 2, and the entrance of exhaust line 3 is on the top of joint 2.
During mud grouting, grouting pipeline 1 is connected with the slush pump pipeline, and joint 2 band screw threads one end is connected with down-hole casing.Mud pours into the down-hole by grouting pipeline 1, is discharged by exhaust line 3 after the Compressed Gas in the filling process circulates in joint 2 and rises, and can reach the purpose of the exhaust while being in the milk.
