Abstract

The utility model relates to a light crow mounting well drilling slurry device which belongs to the associated equipment of truck-mounted drilling rigs on oil fields. The utility model is provided with a crow seat which is provided with a power system, a slurry pump and a sucking-in pipe assembly and a discharging pipe assembly thereof, and a control box connected with a pneumatic system. The slurry pump has five pump heads, and each pump head is one by one connected with crossheads connected into whole in five slide rails through pistons in respective cylinder body. Crankshafts connected with the crossheads are connected with a power input shaft arranged on a pump body through a gear pair, and the power input shaft is connected with a transmission shaft connected with an automatic power system. After the utility model uses the five cylinder slurry pump and runs with speed increase, the utility model reduces volume, raises discharge amount and solves the problems that the present well drilling slurry device has heavy and big structure, inconvenient movement and installation, and thus, the predominance exertion of the quick movement of the truck-mounted drilling rigs is influenced. The light slurry device can not meet the discharge amount required in the well drilling operation.

Description

Lightweight skid drilling mud device

Technical field

The utility model relates to the oil drilling mud device, especially is the matched mud device of vehicular rig.

Background technology

The vehicular rig is that, superior performance strong with movement is the oil field that purpose was developed and was applied to particular type, yet, current and the supporting mud device of vehicular rig, but still big, the cumbersome apparatus that difficulty is installed of volume.Existing this mud device, the pneumatic system that comprises dynamical system, slush pump and suction manifold thereof and exhaust manifold, control cabinet, links with control cabinet, be contained in the mechanical type pressure limiting device that pump main converges, overall distribution is formed a heavy operation architecture more than 24 tons on two sled seats.Causing this principal element of installing huge heaviness is wherein slush pump, this be because, in order to make pump energy long time continuous working, slush pump is designed to three cylinder piston pumps of long stroke, low jig frequency, enlarged bore piston, so, special only be used for loading slush pump with a sled, and all the other equipment will other with a sled.Like this, the advantage of vehicular rig fast moving is restricted.

In order to solve this difficult problem, petroleum machinery equipment manufacturers have developed multi-form lightweight mud device in succession both at home and abroad, and common ground is the size of dwindling three cylinder pump, and mud device integrally is installed on the base.Yet, therefore, reduced and pump delivery is corresponding also though reduced volume weight significantly, can not satisfy in the brill, the requirement of deep-well, generally can only with the workover rig adapted.

Summary of the invention

The purpose of this utility model provides that a kind of volume is little, in light weight is convenient to movement, and the big energy of discharge capacity satisfy bore in, heavy duty service require with the supporting lightweight skid drilling mud device of vehicular rig.

Above-mentioned purpose is achieved by following scheme: change the slush pump in the mud device into five cylinder piston pumps by three present cylinder piston pumps, and its rotating speed of corresponding raising.As further perfect, on the suction manifold of pump, increase the suction device for casting, to strengthen the inlet capacity of pump; For adapting to long time continuous working under the heavy load, forced action type outer circulation lubricating arrangement is installed for the gear of dynamical system and slush pump, it is carried out forced feed lubrication and cooling; For reducing the pulsatile impact of discharge pressure under the big discharge capacity, on the exhaust manifold of pump, to install and discharge damper, whole device is installed on the sled seat.

Experiment showed, after adopting the operation of five cylinder slush pump speedups, make the current relatively lightweight mud device of discharge capacity improve 50%, can satisfy in the brill fully, the requirement of heavy duty service.After the cylinder body of pump is increased to five, cylinder body length and cylinder diameter are reduced, thereby its volume and weight, the three cylinder pump also littler than discharge capacity significantly diminishes, even increased the attachment device that improves the slush pump service behaviour, whole mud device is installed concentratedly on a sled seat, realized easily moving and lifting.After the well site moves into place, only need to connect peripheral manifold, just can construct, realized supporting with the operation of rig fast moving.When the discharge capacity that makes this device improves, by set suction device for casting, discharge the forced lubrication device on damper, gearbox and the slush pump, also make this device possess functional reliability under the high rotating speed long-time continuous of heavy load job status.
