Problems solved by technology

Due to the soft soil and high sand content in this area, when the drilling operation is carried out, the well hole is easy to collapse after the drilling tool is lifted out, and it is not easy to maintain. This makes it impossible to place the mud gun that needs to be placed in the well hole to activate the mud gun. motivating homework

Embodiment 1

[0014] Embodiment 1: as figure 1 , figure 2 Shown in the figure is a mud gun drilling tool, specifically a geophysical prospecting device used in swamps with high sand content and beach-sea transition zone areas.

[0015] The special ground conditions in areas such as swamps and beach-sea transition zones make the traditional operation mode impossible for construction. The present invention analyzes the traditional operation mode and combines the construction ground conditions to invent a mud gun drilling tool. The device adopts a double-cone structure, which can simultaneously complete the mud gun excitation operation while realizing the drilling operation, and can be easily It is well applied in this area and effectively solves the problem of exploration and construction in this area.

[0016] figure 1 Shown is a mud gun drilling tool, which consists of an upper cone 1, a mud gun 2, a drill pipe connector 3, an upper slip 4, a lower slip 5, an air outlet 6 and a lower co...

Embodiment 2

[0019] Embodiment 2: as figure 1 , figure 2 As shown, a mud gun drilling tool, the thread of the drill pipe joint 3 is connected with the standard drill pipe of the drilling rig; the drill pipe joint 3 is fixed with the upper cone 1 through the upper slip 4; the upper cone and the lower cone are also Fixed by the lower slip 5; thereby forming the main structure of the mud gun drilling tool; the mud gun drilling tool is a hollow structure, the upper cone 1 is composed of two semi-tubular structures, and the semi-tubular structure is composed of the upper slip 4 and the lower slip 5 is fixed to form a hollow structure, and the mud gun 2 is installed in the hollow structure; an air outlet 6 corresponding to the air port of the mud gun 2 is opened on the wall of the upper cone 1 .

[0020] When the mud gun 2 needs maintenance, the upper slip 4 and the lower slip 5 are disassembled, and the upper cone can be decomposed into two semi-tubular structures, and the mud gun 2 can be ta...

Abstract

The invention discloses a mud gun drilling tool and a process method and belongs to the technical field of geophysical exploration. A screw thread of a drill rod connecting head is connected with a standard drill rod of a drilling machine; the drill rod connecting head and an upper cone are fixed through upper slips; the upper cone and a lower cone are fixed through lower slips; accordingly, a main body structure of the mud gun drilling tool is formed; the mud gun drilling tool is in a hollow structure, the upper cone is composed of two semi-tubular structures, the semi-tubular structures are fixed through the upper slips and the lower slips to form a hollow structure, and a mud gun is installed in the hollow structure; an air outlet which corresponds to an air opening of the mud gun is designed in the wall of the upper cone. The mud gun drilling tool and process method has the advantages that well drilling and borehole inducing of the mud gun can be achieved at a time, and the producing efficiency is greatly increased; well mouth collapse of a high sand content area can be effectively prevented by the aid of the unique double-cone structure, and the inducing effect is improved; the operating area of a mud gun seismic focus system with the drilling tool is widened, operations in areas such as bogs and tidal transitional zones can be excellently performed, and problems of exploration constructions in the areas can be effectively solved.

Description

technical field [0001] The invention relates to a mud gun drilling tool and a process method, belonging to the technical field of geophysical exploration. Background technique [0002] In the oil exploration of the beach-sea transition zone, the traditional operation mode is to first use the drilling tool to drill the hole, and then place the mud gun in the drill hole to activate the mud gun to complete the exploration operation. Due to the soft soil and high sand content in this area, when the drilling operation is carried out, the well hole is easy to collapse after the drilling tool is pulled out, and it is not easy to maintain. This makes it impossible to place the mud gun that needs to be placed in the well hole to activate the mud gun. Motivate homework. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a mud gun drilling tool and a process method. [0004] A kind of mud gun drilling tool, the ...
