Drilling machine complete equipment applied to rock-soil energy storage technology

Abstract

The invention provides drilling machine complete equipment applied to a rock-soil energy storage technology. The drilling machine complete equipment comprises a slurry treatment system, a power system, an automatic control system, a rotary disc torque device, a transmission device, a drilling rod box, a portal frame, a chassis, a mechanical arm and a drilling tool assembly. The added automatic control system and an external remote controller can realize full automation of movement and tripping of the drilling machine, and monitor bit pressure, torque and well deviation in real time. The drilling machine is a reverse circulation drilling machine, a pump suction reverse circulation mode is adopted, a water supplementing pipe and a valve are added, a vacuum pump is not needed for vacuumizing, and water is added through the water supplementing pipe. The wireless logging-while-drilling instrument is placed in the non-magnetic drill collar at the bottom, not only can be used for measuring conventional logging such as resistivity, natural potential and sound waves, but also can be used for measuring drilling parameters such as bit pressure, torque and well deviation, the track of a drill bit can be adjusted in time by utilizing the measured drilling parameters, particularly, the well deviation can be followed up in real time, and the well deviation and well bottom displacement can be controlled in time.

Description

technical field [0001] The invention relates to a complete set of drilling rigs applied to rock-soil energy storage technology, in particular to a new type of automatic, monitorable and controllable underground pipe construction drilling rig. Background technique [0002] In the initial stage of the development of ground source heat pump technology, due to the small workload, there is no special drilling rig for the construction of buried pipes. In China, various existing drilling rigs are generally used for construction, such as rotary table water well drilling rigs, vertical shaft core drilling rigs, wire rope percussion drilling rigs, engineering survey drilling rigs, and engineering construction drilling rigs. The construction technology is also based on conventional rotary drilling and mud circulation; when encountering complex strata such as sand and gravel, sometimes steel wire rope percussion drilling is used. Therefore, the construction efficiency is low, the cost ...

Problems solved by technology

Therefore, the construction efficiency is low, the cost is low, and the use of mud will also cause environmental pollution.

Moreover, when the wireless logging-while-drilling instruments currently on the market detect the depth of the downhole, the detection instrument needs to be put into the depth of the downhole, while the traditional wireless logging-while-drilling instrument does not have a protective structure. When the detection instrument descends, It is easy to collide with the well wall, causing damage to the detection instrument, causing detection deviation, and affecting the detection result
