Abstract: A mechanical automatic vertical drilling tool, with ends that are connected with an upper drilling tool and a bit by a detachable thread, is disclosed. The tool comprises a control device, an actuator and an auxiliary part. The control device detects status of wellbore and controls operations of the actuator when the wellbore leans. The actuator pushes a block out against the well wall to generate a radial force, which pushes against the drill bit to prevent deviation and modify the wellbore trajectory. The auxiliary part transmits the indispensable bit pressure and torque for drilling to assist the control device and the actuator to achieve the function. This disclosure can get automatic deviation correction with only mechanical structures. It is simple and reliable, and unlikely to fail in complicated wells without any manual operation.

Abstract: A mechanical rotary steering drilling tool for steering a drill string includes a test section, a clutch device, a control mechanism, and an execution part. The test section is used as an upper joint in cooperation with the tool. The clutch device is externally connected with a guide body and internally coupled with a mandrel. A groove on a cylindrical surface of a switch control cylinder is matched with a control screw to determine rotation of a fluid channel switch. A pushing block of the execution part extends out against a wellbore wall to push a drill bit for steering drilling after the fluid channel is opened.

Abstract: A drilling tool is disclosed. The two ends of the drilling tool are respectively connected with an upper drilling tool and a drill bit. The drilling tool includes an axial striking part, a torsional striking part, and an auxiliary part. Under the combined action of a spring and a high-pressure drilling fluid, the hammer of the axial striking part generates an axial striking force to strike the upper housing; and the pendulum of the torsional striking part generates a torsional striking force to strike the lower housing. The reversing switch and the center tube are plugged together to simultaneously reverse torsion and axial striking forces, respectively. The high-pressure drilling fluid pushes the hammer and the pendulum to generate axial and torsional striking forces, respectively, to effectively increase the ROP and reduce the stick-slip phenomenon. The drilling tool is stable and reliable in a complex and changeable downhole environment.

Abstract: Disclosed is a method of preparing a carbon quantum dot from soybean dregs by hydrothermal synthesis, including: mixing the soybean dregs with water, and subjecting the reaction mixture under heating at 100-500° C. in an autoclave for reaction; cooling the reaction mixture when the reaction is completed, and removing insoluble substances from the reaction mixture; and dialyzing the reaction mixture, and lyophilizing the dialyzed product to produce the carbon quantum dot. The invention further provides the carbon quantum dot prepared by the above method and a use thereof in the detection of Fe3+ and Hg2+ in water, where the lowest detection limit can reach 30 nmol/L and the detection range is 0.1-50 ?mol/L.

Abstract: The invention relates to an agricultural seeding machine, in particular to a straw crushing and inter-furrow collecting-mulching no-tillage seeder. A straw-crushing device, a guide device, a fertilizer discharging device, and a furrowing and seeding device are sequentially arranged on a rack from front to back. According to the guide device, a plurality of straw-crushing guide assemblies having installation positions capable of being horizontally adjusted are arranged on an adjustment crossbeam, are in a prow shape, and each consist of a rear vertical back plate formed with a fertilization port, and two front symmetrical oblique guide plates. Straw is orderly spread on straw mulching belts between seeding belts while being crushed within the working range, and thus, the seeding belts are free of straw obstacles. The straw crushing and inter-furrow collecting-mulching no-tillage seeder is high in working integrity, easy to assemble, and low in energy consumption.
