TAGRAS Holding 的系统服务部门开发并制造了带有接箍和用于连接套管的接头的 PDC 钻头。该设备用于套管钻孔。如今，它是最先进的钻井方法。
LLC“erekryvatel”子公司的专家们设计了一套原创系统，用于在直径为 245 mm 的套管柱上进行复杂的试点工作，然后以 50-350m 的间隔进行固井。作为设计测试的一部分，穿透深度为 307 米。 ROP 达到 31.83 m/h，而计划为 20 m/h。
新型设备的引入，与标准技术相比，引导段建井周期将缩短18小时。当穿过容易发生山体滑坡的不稳定岩石时尤其如此。
经过
The Sistema-Service Division of TAGRAS Holding has developed and manufactured a PDC bit with a collar and a sub for connecting casing pipes. The equipment is used for drilling on casing pipes. Today it is the most advanced drilling method.
Specialists on the basis of a subsidiary of the division LLC “Perekryvatel” designed an original system for conducting a complex of pilot works on a casing string with a diameter of 245 mm, followed by cementing in an interval of 50-350m. As part of the design tests, the penetration was 307 meters. ROP reached 31.83 m/h against the planned 20 m/h.
The introduction of a new type of equipment will reduce the well construction cycle in the conductor section by 18 hours compared to the standard technology. This is especially true when passing through unstable rocks prone to landslides.
