The National Energy Administration website, August 29, the National Energy Administration organized a shale oil exploration and development work conference and pointed out that increasing the scale of shale oil production in all directions and promoting the shale revolution is of great significance to the domestic and national energy security. In view of the next step of work, the meeting put forward five requirements: first, to emancipate the mind and increase investment in shale oil exploration and development; second, to strengthen faith and do a good job in improving shale oil recovery rate; third, to drive innovation and give full play to the leading role of scientific and technological innovation; fourth, to adhere to ecological priority and comprehensively promote the green and low-carbon development of shale oil; fifth, to strengthen policy support


Manufacturing method of improved drill tail front guide sleeve

2022-08-17

The technical problem to be solved by the utility model is to provide an improved drill tail guide sleeve, which improves the existing drill tail guide sleeve, increases the amount of lubrication by adding lubricating oil holes, and reduces the hard impact of components by replacing materials. The utility model effectively solves the problem that the drill pipe is easy to break during the use of the hydraulic rock drill, and has the characteristics of increasing the amount of lubrication, preventing the drill pipe from breaking, reducing the cost of production operation and eliminating the hidden danger of safety.

2022-07-28

What are the classification, installation and preparation of DTH drills? There are two kinds of rock drills and drilling rigs. Drilling rigs are divided into open-pit drilling rigs and underground drilling rigs. ① Rock drill: used to drill holes in rocks of medium hardness and above, with a diameter of 20-100mm and a depth of less than 20 meters. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drills, of which pneumatic rock drills are the most widely used.


Type of high-pressure down-the-hole drill bit and quality requirements for lubricating oil of drill bit

2022-07-18

There are four main types of end face designs used in high-pressure down-the-hole drills: convex end face, flat end face, concave end face and deep concave central end face. Cemented carbide is mostly used in the common tooth distribution mode of ball teeth, spring teeth or ball teeth and spring teeth. 1, the end face convex type: the drill bit is divided into single boss and double boss end face two forms, the latter is mainly used for larger diameter down-the-hole drill. The convex down-the-hole drill can maintain a high drilling speed when drilling into hard and hard abrasive rocks, but the straightness of the drilling is poor, so it is not suitable for rock drilling projects with high straightness requirements.
