Abstract
A top driving special purpose lower sleeve slurry filling device comprises a slurry pump connector, a union, a slurry filling tube, a sleeve circulating cap, a slurry discharge pipe and a control valve. The top driving special purpose lower sleeve slurry filling device is characterized in that the upper portion of a slurry pump connector is connected with the slurry pump, the lower portion is connected with the upper end of the slurry filling tube through a high pressure union, the lower end of the slurry filling tube is connected with an inlet of the sleeve circulating cap, the lower end of the sleeve circulating cap is connected with a sleeve, the upper end is connected with the slurry discharge pipe through the high pressure union, the terminal end of the slurry discharge pipe is inserted into a ring-shaped space between the sleeve and the ground layer, and the control valve is arranged on the slurry discharge pipe. The utility model provides a top driving special purpose lower sleeve slurry filling device which is safe, environment-friendly, convenient and rapid, and guarantees the smoothness of the construction operations.
Description
One, technical field
The utility model relates to a kind of top and drives special-purpose setting of casing mud grouting device.
Two, background technology
Need in the sleeve pipe lower going-into-well during oil gas well cementation, float collar generally all is equipped with in the bunch tube bottom, the effect of float collar is equivalent to a ball-and-seat, fluid can only unidirectionally enter annular space from sleeve pipe, therefore be empty at setting of casing process middle sleeve, need frequently in sleeve pipe, to pour into mud, otherwise can't be lowered to when buoyancy sleeve pipe when conducting oneself with dignity from well head.In addition,, cause and empty oversizely in the sleeve pipe pipe, can cause sleeve pipe to be squeezed and damage, will have a strong impact on the cementing operation operation if sleeve pipe is lowered to too fast or mud pours into untimelyly.
In setting of casing mud grouting process, need the air in the sleeve pipe is discharged, if well depth is excessive or mud pours into too fast, can cause air to discharge the untimely sleeve pipe that causes builds the pressure, pressure-air in the sleeve pipe can carry part mud ejection well head, so not only influence construction progress, and waste mud contamination environment, the cleaning work in later stage also can cause manpower, waste of time.The more important thing is when the down-hole runs into complex situations, can not in time be controlled, cause the generation of peril easily.
As seen there are a lot of problems in conventional mud grouting method, can not satisfy the demand of setting of casing mud grouting, the utility model has overcome above various drawbacks, provide a kind of safety and environmental protection, conveniently the top drive special-purpose setting of casing mud grouting device, guaranteed carrying out smoothly of construction operation.
Three, summary of the invention
The purpose of this utility model provides a kind of top and drives special-purpose setting of casing mud grouting device, solves the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of slush pump joint, union, notes mud tube, sleeve pipe circulation cap, discharge pipe and control valve, it is characterized in that slush pump joint top is connected with slush pump, the bottom is connected with notes mud tube upper end by the high pressure union, annotating the mud tube lower end is connected with the import of sleeve pipe circulation cap, sleeve pipe circulation cap lower end is connected with sleeve pipe, the upper end is connected with discharge pipe by the high pressure union, and the terminal annular space that injects between sleeve pipe and the stratum of discharge pipe is provided with control valve on discharge pipe.
Slush pump joint one end is provided with box thread, is connected with the slush pump outlet, and the other end is welded with high pressure union joint, is connected with the notes mud tube.
Sleeve pipe circulation cap is made as cylindrical, and the upper end is welded with high pressure union joint, and the bottom is provided with male thread, be connected with sleeve pipe, the middle part is welded with the mud import that has high pressure union joint, is connected with the notes mud tube, the upper end is provided with the high pressure union, is connected with discharge pipe, and discharge pipe is provided with control valve.
Mud was directly from sleeve pipe uphole end ejection problem when the utility model had solved under the oil gas well cementing operation pipe box, mud waste and environment pollution have been avoided, if when running into high or other complex situations of down-hole pressure and need stop to reclaim mud, shut the control valve on the discharge pipe, the top is driven with pipe box and is formed closed-cycle system rapidly, even and can the turn on pump circulating mud, guaranteed that pipe box well cementing operation safety carries out smoothly.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model,
1-mud joint 2-high pressure union 3-annotates mud tube 4-control valve 5-discharge pipe 6-sleeve pipe circulation cap among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
As shown in Figure 1, the utility model is made up of slush pump joint 1, high pressure union 2, notes mud tube 3, sleeve pipe circulation cap 6, discharge pipe 5 and control valve 4, it is characterized in that slush pump joint top is connected with slush pump, the bottom is connected with notes mud tube upper end by the high pressure union, annotating the mud tube lower end is connected with the import of sleeve pipe circulation cap, sleeve pipe circulation cap lower end is connected with sleeve pipe, the upper end is connected with discharge pipe by the high pressure union, the terminal annular space that injects between sleeve pipe and the stratum of discharge pipe is provided with control valve on discharge pipe.
When using the utility model, slush pump joint 1 is connected with notes mud tube 3 by high pressure union 2, annotating mud tube 3 other ends is connected with sleeve pipe circulation cap 6, sleeve pipe mud cap lower end is connected with casing coupling, the upper end is connected with discharge pipe 5, and the discharge pipe end is inserted in the annular space between sleeve pipe and the stratum.Annotate mud tube and discharge pipe and all adopt high-pressure hose; stochastic activity when being convenient to setting of casing; when with setting of casing with when well cementation; the mud that is returned well head by gas enters in the annular space between well head sleeve pipe and the stratum by discharge pipe; with on the well cementation mud that returns together participate in well cementation; avoided mud to spray outward; protected environment; save mud, when the down-hole produces abnormal conditions, shut by-pass valve control; stop to reclaim mud; the top is driven with sleeve pipe and is formed closed-cycle system rapidly, and in time turn on pump circulates, and has guaranteed that setting of casing well cementing operation safety carries out smoothly.
