Abstract
The utility model relates to a tool which is used for grouting mud into a casing pipe during the construction operation of casing running, in particular to a casing pipe grouting tool, and provides the casing pipe grouting tool which is safe, convenient and fast, and capable of guaranteeing the safe running of the construction operation and preventing the mud from being injected to a drill floor surface. The casing pipe grouting tool comprises the casing pipe (3). An union (4) is arranged on one side of the casing pipe (3), a male pin is arranged at the lower end of the casing pipe (3), a cover plate (5) is arranged at the upper end of the casing pipe (3), a gas discharging central pipe (1) penetrates through the casing pipe (3), a saw-toothed baffle (6) is arranged inside the casing pipe (3) outside the gas discharging central pipe (1), and the gas discharging pipe (1) is provided with a gas discharging pipe union (2). By the adoption of the structure, the safety running of the construction operation can be guaranteed, the mud is prevented from being injected to the drill floor surface, the time for grouting the mud is saved, and efficiency is improved. At the same time, the casing pipe grouting tool is simple in structure, low in cost, safe and convenient to operate and time-saving, reduces unsafe factors, and is beneficial for safe production, capable of grouting the mud into the casing pipe continuously, and time-saving.
Description
Technical field
The utility model relates in the oil drilling when the setting of casing construction operation a kind of instrument that pours into mud in the sleeve pipe, especially a kind of sleeve grouting instrument.
Background technology
At present, drilling crew in the setting of casing process in the sleeve pipe the employed instrument of mud grouting rubber pipeline and iron pipe line are arranged, when mud grouting in sleeve pipe, mud forms column liquid in sleeve pipe, the compressed following gas column that forms of air in the sleeve pipe, gas column heads on mud and rises, during to certain altitude, the interior air of sleeve pipe heads on mud and sprays in sleeve pipe, drilling floor surface is mud everywhere, causes working environment contaminated, causes difficulty to construction, using rubber pipeline and iron pipe line mud grouting to fill with a period of time mud will exhaust a period of time, so again and again mud grouting prolongation setting of casing time.It is time-consuming to require great effort, and dangerous.Given this, a kind of safe, sleeve grouting instrument easily of ad hoc meter.
Summary of the invention
It is a kind of safe, convenient that the utility model provides, and can guarantee that the safety of construction operation is carried out, and avoids mud to be sprayed onto drilling floor surface, saves the mud grouting time, the sleeve grouting instrument of raising the efficiency.Its technical scheme is that the sleeve grouting instrument comprises sleeve pipe, and sleeve pipe one side is provided with union, and the sleeve pipe lower end is provided with pin thread, the sleeve pipe upper end is provided with cover plate, pass the exhaust center pipe in the sleeve pipe, the exhaust center pipe is provided with the zigzag baffle plate outward in the sleeve pipe, and the exhaust center pipe is provided with the stack union.Adopt after the said structure, mud flows into the sleeve grouting instrument, and the interior zigzag baffle plate of instrument is divided into many threads to the mud that flows into and flows in the sleeve pipe, and air upwards returns from mud gap in the sleeve pipe, and the interior air of sleeve pipe is discharged from central tube, is discharged into well head by sebific duct.The safety that can guarantee construction operation is carried out, and avoids mud to be sprayed onto drilling floor surface, saves the mud grouting time, raises the efficiency.Simultaneously simple in structure, cost is low; Handling safety, convenience, laborsaving; After sleeve pipe was filled mud, unnecessary mud advanced well head from the central tube discharge currents, and working environment is clean, reduced unsafe factor, was conducive to safety in production; Can in sleeve pipe, pour into mud continuously, save time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The sleeve grouting instrument comprises sleeve pipe 3, and sleeve pipe 3 one sides are provided with union 4, and sleeve pipe 3 lower ends are provided with pin thread, sleeve pipe 3 upper ends are provided with cover plate 5, pass exhaust center pipe 1 in the sleeve pipe 3, be provided with zigzag baffle plate 6 outside the sleeve pipe 3 interior exhaust center pipes 1, exhaust center pipe 1 is provided with stack union 2.
(1) during use, buckling to cannula carrier on the sleeve pipe grouting tool pin thread; (2), 1. water cage band is received on number union; (3), 2. the exhaust hose line is received on number union; (4), turn on pump mud grouting.
