Drilling thruster for petroleum exploitation and its application method

Abstract

The invention discloses a drilling propeller for oil exploitation and a method for using the same, which belong to the field of oil exploitation and relate to drilling technology for oil exploitation; it includes a propeller body, and one end of the propeller body is provided with a fixing assembly for fixing the propeller body The inside of the propeller body is provided with a driving part, and one side of the driving part is provided with a drilling rod for oil exploitation, and the end of the drilling rod away from the driving part is fixedly connected with a drill bit, and through the cooperation of the water tank and the outlet pipe, the impact of the drill bit is buffered. The impact damage of the ground floor can greatly reduce the torque fluctuation range brought by the impact to the ground floor, prolong the working life of the drill bit and drilling tools; make the thruster work normally in use; the structure of the thruster is simple, easy to manufacture, and low cost , Easy maintenance; the telescopic sheath is easy to replace, and the cooperation between the fixed component and the propeller body can quickly install the propeller body in the fixed component, which is convenient for the staff to reinstall the fixed component and improves the efficiency of oil exploration .

Description

technical field [0001] The invention belongs to the field of petroleum exploitation, in particular to a drilling thruster for petroleum exploitation and a method for using the same, and relates to the drilling technology for petroleum exploitation. Background technique [0002] Oil extraction refers to the behavior of digging and extracting oil in places where there is oil storage. During the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead; the current oil or other In geological drilling work, the basic combination of the drill string is the combination of drill pipe, drill collar and drill bit. In order to improve the drilling quality and drilling speed, or to perform directional drilling, it is necessary to increase the space between the drill collar and the drill bit. Power drilling tools such as stabilizers and screw drilling tools with righting function; during the drilli...

Problems solved by technology

[0003] Due to the low drilling efficiency of intermittent drilling, it will also bring continuous impact damage and sliding wear to the drilling edge of the drill bit. In addition, the drill pipes, drill collars and other drilling tools that make up the drill string are all rigid. Rods, under the gravity similar to the drilling pressure, generate strong impact and heat on the surface being drilled, and need to cooperate with water to slow pressure and cool down. The current drilling equipment cannot control and adjust the water volume well, so It will cause a waste of water resources, and during the use of the propeller, frequent picking will reduce the service life of the drill bit. Therefore, we have to propose a new design
