The East-West glass slide is a glass slide or quartz slide that is used to place a glass slide or quartz slide when it is observed under a microscope. During production, a cell or a sample containing a certain tissue is randomly placed on the slide glass, and a cover slip is placed on it for observation a similar material that produces a phase difference.

Chuanshi Brand SV series six-point positioning high-speed motor drill bit, specially designed for directional wells and horizontal well bottom-drilling drilling. This series of drill bit forgings features a new integrated jaw back structure with the nozzle seat outer wall and the claw back simultaneously touching the well wall. The realization of the quasi-six-point positioning function of the drill bit reduces the vibration of the drill bit, makes the drilling more stable and ensures the quality of the well body; the hard alloy tooth is embedded on the outer wall of the nozzle seat to effectively protect the nozzle seat and meet the requirements of the high-speed drilling system for the hydraulic system. The bearing adopts high-precision matching sliding bearing and advanced metal seal... After a series of enhancements, this type of drill bit is the “heavy weapon†in the drill bit family, and it is the first choice for directional well and horizontal well drilling.
In the Lotus 000-X2 well, the first six-point positioning high-speed motor drill bit meets five layers of shale and fine sandstone interbeds, and produces 46.42 hours of pure drilling, 72.41 meters of footage, and a good drilling speed of 1.56 meters per hour. Immediately thereafter, the four drills refreshed the drilling record of the fastest and the longest drilling time in the Xujiahe Formation.
4 Chuanshi brand SV series six-point positioning high-speed motor drill bit from the Wushen into the well, under the screw plus turntable condition, smoothly drilled to the required three, compared with the domestic and foreign manufacturers of adjacent wells, the average mechanical drilling rate, the average single Only the footage is doubled. In August, a number of “bits giants†competed in the southwest oil and gas field lotus structure Xujiahe, and the “Chuanshi†brand drills won the first prize.
