| description | The invention discloses a downhole directional hydraulic jet tool used for fracturing acidization improvement. The downhole directional hydraulic jet tool comprises a control device, a driving device and a jet gun which are sequentially connected. The control device comprises a control cavity body, a signal receiver, a control circuit board and a downhole battery pack. The signal receiver, the control circuit board and the downhole battery pack are all arranged on the control cavity body. The signal receiver is connected with the control circuit board which is electrically connected with the driving device and connected with a gravity acceleration sensor. The downhole battery pack is connected with the signal receiver, the control circuit board and the driving device which comprises a driving motor. The jet gun is fixedly connected with a motor rotor of the driving motor. The downhole directional hydraulic jet tool can adjust the orientation of a jet hole, can effectively prevent the influence of downhole res |
