Abstract
Deep penetration of radial horizontal drilling techniques from existing within the wellbore radial drilling in formation, is for the old oil fields, the marginal oil field, low permeable reservoirs and coal bed methane development provides an effective recovery or economic means to improve the single well production. Using integrated hydraulic deep penetrating technology of downhole tools can be up to 2 m length of horizontal drilling, hole diameter 20–50 mm, can effectively penetrate the drilling, completion and conventional shells perforating technology in the form of pollution area near wellbore area, to penetrate auxiliary directional fracturing can effectively transform low permeability fractured reservoir. Using the radial jet of step-by-step horizontal drilling technology, use under continuous tube on drilling tools, horizontal drilling length of 20–50 m or more. It points out the traction ability of nozzle and drilling performance is the length of the horizontal drilling and for the key factors influencing the maximum range.
