| description | The invention provides a water jet drill radial well operation method. The water jet drill radial well operation method comprises the following steps that step 10, an oil pipe column and a positioningguide tool are connected and descend to the depth to be operated in a well; step 20, a casing drilling tool is put into the well to perform casing windowing operation; and step 30, a stratum drillingtool is put into the well for drilling, so that the rock breaking speed of the stratum drilling tool is consistent with the feeding speed. The method has the beneficial effects that the diameter of the formed hole is only slightly larger than the outer diameter of the spraying pipe, smooth feeding of the spraying pipe in the formed hole is guaranteed, the supporting and centralizing effects can be provided for the spraying pipe, the spraying pipe is fed in a linear state in the radial hole forming process smoothly at a low speed, , and therefore it is guaranteed that the drilling distance isfarther, and the final radi |
