A method to optimize the length of flexible hose of the radial jet drilling technology

Abstract Radial jet drilling (RJD) technology has been applied to enhance the recovery of difficult-to-produce reserves by multiple horizontal micro-holes. The micro-hole length drilled high-pressure water jets is vital importance for oil and gas effect usually tens meters long applications in maturing fields China. are generated orifices nozzle generally. Many studies focused on improving self-propelled force increase length. However, there few researches extension capacity terms optimizing flexible hose that acts as drill pipe conventional technology. This paper firstly studied relationship between limit according analytical model calculate limit. Then, method optimize flow rate was developed aiming obtain maximum results show decreases logarithmically with under condition takes value. optimization a field case proved be effective study significant improve capacity. Moreover, it provides reference design hydraulics selection RJD.
