Introduction to the five characteristics of the cable drill pipe reamer-Yikuang Technology
The five characteristics of the cable drill pipe reamer are introduced. The cable drill pipe reamer has the following characteristics: ① The cable reamer can stir up the cinder deposited in the hole to improve the slag discharge capacity of the drill pipe, and can also play a secondary cutting role to reduce the cinder and facilitate the slag discharge. ② When the cable drill pipe encounters caving and hole collapse, the cable reamer can ream and then discharge the cinder at the collapsed hole to avoid sticking and burying; ③ Ensure the normal transmission of signals in the drill pipe during the drilling process; ④ When the drill hole has a sharp turn, the hole with large curvature can be reamed to realize the smooth transition of the drilling trajectory and avoid sharp bends; ⑤ According to different formation conditions, the drill pipe and the reamer

The main role of the shell part of the cable drill pipe reamer-Yikuang Technology.
The main function of the shell part of the cable drill pipe reamer is to ensure the strength of the cable drill pipe. The shell adopts an integral structure, and the modulated high-quality alloy steel is selected. The male and female joints are respectively processed at both ends of the outer tube to improve the overall strength. The blade slot adopts a large-diameter arc transition to avoid the reduction of the mechanical performance of the shell due to stress concentration.

Formation Principle and Influence of Directional Drill Pipe -- Yikuang Science and Technology
The formation principle and influence of directional drill pipe near horizontal directional drilling technology is an advanced technology in the field of drilling engineering. It is applied to coal mines and started in the western developed countries such as the United States, Germany and Britain in the 1960 s and 1970 s. Many coal mines in my country, such as Songzao, Tiefa, Huainan, Shanxi Yamai Daning, etc., also introduced this technology in the mid-1990s. At present, China's coal mines are widely used in directional drilling technology for the screw motor oblique supporting wired drilling measurement system. This technology is mainly used in underground rock formations and more stable coal seams because of its high precision, long distance and construction flexibility.

The Cause of Remanence of Directional Drill Pipe -- Yikuang Science and Technology
Analysis of the causes of remanence caused by directional drill pipes The reasons for remanence caused by directional drill pipes are as follows:(1) metal melting or pipeline manufacturing process;(2) The pipeline is stopped in a strong magnetic field;(3) Non-destructive testing by magnetization method;(4) Preheating the weld joint by electromagnetic induction method and heat treatment to produce remanence;(5) Cutting lathe grinding wheel grinding groove;(6) The axis is consistent with the direction of the geomagnetic field and is magnetized by the geomagnetic field due to impact or vibration.

Yi Mine's "Place Code" is on line. Everything you want to know is here.
The current situation of the new coronary pneumonia epidemic is grim and complex in order to comprehensively do a good job in the normalization of the epidemic precision prevention and control work in the city to promote the use of epidemic prevention "place code" to ensure the safety of the people's lives and health on the place code, small compilation of the following common questions and answers hope to help you what is the place code? Shandong place code (hereinafter referred to as "place code") is a proprietary two-dimensional code used by citizens to enter the key places in Yuncheng City, is the new crown pneumonia epidemic prevention and control normalization, precision, information-based important measures, through scanning code records can quickly trace the relevant personnel activity track and close contact personnel, to avoid the spread of the epidemic.

Have you ever used these drill pipe and drill bit fishing methods?
In the process of large-diameter pile foundation construction of rotary excavators, accidents of hole collapse and burying and holding occur from time to time, but the causes, accident conditions and site conditions of rotary excavators are not the same, so the measures taken are not the same, and sometimes several treatment methods may need to be used. The editor focuses on the treatment method of buried drilling, and describes the processing tools in detail, hoping to communicate with peers. After the burying or holding accident, the mud performance shall be adjusted in time to control the further expansion of the accident, and the causes shall be analyzed in time to take corresponding measures, so as not to miss the best treatment time. The treatment of buried drilling can be summarized as "cleaning, penetrating, topping, frying, expanding,
