Tuha Oilfield drilled a new record in horizontal wells
On July 31, the reporter learned from Tuha Oilfield Exploration Company that China Petroleum Corporation's tight sandstone key exploration well Ji 4H completed the drilling and completion operations of the kilometer horizontal section, and created the longest record of the horizontal section of the Tuha horizontal well. The Ji 4H horizontal well is a key exploration well deployed in the Tushan arc belt of the Tuha Oilfield. During the drilling process, technicians drilled high-efficiency PDC bits and screws according to the lithology and stratigraphic characteristics of the area. The drilling cycle was reduced from 76.5 days to 53 days, and the average speed was increased from 4.03 meters per hour to 6.19 meters. For the first time, the Ji 4H horizontal well completed the small wellbore sliding casing cementing operation in the Tuha oil field, and the casing was successfully inserted once.

Axicon (conical lens) is a conical prism used to create non diffractive Bessel beams
Axicon lenses are conical lenses which, when followed by a conventional lens, can focus laser light to a ring shape. Using an axicon together with a Spherical Lens will produce an annular focus for hole drilling applications. We offer Plano-Convex , Plano-Concave, Double Convex Axicons.
