Turbo drilling

High-speed Turbodrilling

Petro-king owns a completely new designed turbodrill which is known as the TurboDynamics series, and formed a unique effective technology for fast drilling for igneous rock, gravel layer, highly-abrasive quartz sandstone, in combination with uniquely-designed diamond-impregnated bits.

In order to improve  drilling efficiency, by extending the life of drilling tools, and to provide a quantum leap in overall drilling performance in certain targeted applications, Petro-king has established a service system for the whole drilling process from design to execution through the provision of a high technology turbo-drilling service.. When applied in the correct application turbo-drilling can generally save drilling time by 40%-50% and overall drilling cost by 1/3. Hole quality is also often greatly improved which reduces the well bore tortuosity while drilling and can facilitate easier running of casing or production liner strings. Turbo-drilling is particularly well suited to deep wells, heavy mud weight scenarios, high down hole temperatures and formations that exhibit  poor drillability by conventional means. Taking into account different formations and well conditions, Petro-king can provide various combinations of diamond-impregnated bits and turbodrills of various configurations, which have been successfully used to drill directional wells, horizontal wells and high-deviated wells. At present, Petro-king has a 70% market share in the domestic turbo-drilling sector.

Technical Advantages

Compared with the conventional rotary drilling method,

· Turbodrills can double the average ROP, and greatly extend the number of meters drilled in a single run. 

· By saving on the trip time, turbo-drilling has been proven to shorten the overall time to drill a hole section by 55% thereby lowering the overall drilling cost by 30%.

· Turbo-drilling technology has been proven to be a highly effective  method to improve drilling performance in gravel layers, igneous rock and high abrasive quartz sandstones.

· Turbo-drilling technology is fully fit for the High temperature wells.
