Abstract: It has developed the second era horizontal drilling system is using the high-pressure jets method.By the way,multi side tracking well holes can be drilled at the same depth,and do not need to trip the whipstock out.The system said above can provide the 3-D logging without and output information of the well path.The tension in the static pressure and the control ability can be increased using a new drive system forced by a hydraulic power at the end.With this system,some technologies such as the gravelpacked completion,the field electrolysis perforations and the flexible slotted liner etc.are being developed and perfected.Initial results have been got after producing.
