In order to achieve the above purpose, the utility model adopts the following technical scheme:

a creep into drive arrangement for oil-well rig, including the derrick, be fixed with the rig carousel on the derrick, the rig carousel fit in is connected with the drilling rod, has linked the drill bit in the one end cooperation of drilling rod, still is equipped with the protection casing on the drilling rod, and the protection casing outside is equipped with a set of through-hole, is equipped with a set of sensor in the protection casing, and the sensor is all installed on the drilling rod, and rig carousel upside is equipped with cooling device.

Preferably, the cooling device comprises a circular groove body, a layer of steel wire filter screen is arranged in the circular groove body, and a group of handles are arranged on the steel wire filter screen.

Preferably, the lower side of the derrick is provided with a mud collector which is arranged on the ground.

Preferably, a mud pump is arranged on one side of the derrick, and a mud pool is arranged on one side of the mud pump.

Preferably, the mud collector is connected to a water inlet of the cooling device through a pipeline, a water outlet of the cooling device is connected to a water inlet of the mud pump through a pipeline, and a water outlet of the mud pump is connected to the mud pit.

The utility model has the advantages that: the utility model discloses can use the shaft bottom to beat the mud that comes and cool off the carousel, effectually prevent because the condition that the carousel became invalid and then make the device of creeping into and became invalid of high temperature, promote the stability of rig.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in figures 1-3, the utility model provides a creep into drive arrangement for oil-well rig, including derrick 1, be fixed with rig carousel 7 on derrick 1, rig carousel 7 fit in is connected with drilling rod 3, rig carousel 7 can transmit enough big torsion and necessary rotational speed and be used for the dive of drilling rod, rig carousel 7 uses high-power diesel engine unit 11 to drive, power is abundant but great torsion can cause the too big problem of calorific capacity, it has drill bit 4 to link in the cooperation of one end of drilling rod 3, still be equipped with protection casing 5 on drilling rod 3, protection casing 5 can prevent that its inside sensor from receiving the damage, the protection casing 5 outside is equipped with a set of through-hole 5.1, through-hole 5.1 is used for passing through of mud so that the sensor is more audio-visual detects mud, be equipped with three sensor 6 in protection casing 5, the type of three sensor 6 is temperature sensor respectively, The pressure sensor, the liquid density sensor, except the liquid density sensor which is sturdy and durable, the other two sensors are all explosion-proof sensors, and the three sensors are all arranged on the drill rod 3.

The lower side of the derrick 1 is provided with a mud collector 2, which mud collector 2 is not illustrated here for the prior art in the field, and the mud collector 2 is arranged and fixed on the ground.

7 upsides of rig carousel are equipped with cooling device 8, cooling device 8 includes ring shape cell body 8.1, be equipped with the annular steel wire filter screen 8.2 of one deck in ring shape cell body 8.1, be equipped with a set of handle 8.3 on steel wire filter screen 8.2, it is fixed with the ring lid that is used for sealed ring shape cell body 8.1 to use the hasp on ring shape cell body 8.1, when being full of impurity in ring shape cell body 8.1 when the operation, the ring lid can be opened, use handle 8.3 to carry out the clearance with steel wire filter screen 8.2, ring shape cell body 8.1's degree of depth is 50cm, great degree of depth can effectively prevent small-size mineral material jam.

The derrick is characterized in that a mud pump 9 is arranged on one side of the derrick 1, a mud pool 10 is arranged on one side of the mud pump 9, a water tap is hung on the derrick and connected into the mud pool and powered by the mud pump 9, the water tap is used for flushing mud in the mud pool into a well bottom through a drill rod, controlling bottom layer pressure and cooling a drill bit, and the water tap is drawn in the drawing in the prior art.
