Other AbstractThe present utility model relates to an earth oil down-hole drilling device, concretely relating to a novel earth oil down-hole horizontal drilling assembly capable of drilling on the wall of a steelsleeve, the cement and the lithosphere through one-time of going down, the novel earth oil down-hole horizontal drilling assembly comprises an executing mechanism, a power source tightly connected with the executing mechanism having an inner layer, a middle layer and an outer layer, a drilling device for drilling on the wall of a steel sleeve and a guider for the drilling of a layer of cement andthe lithosphere, wherein, the drilling device and the guider move to and fro by the driving of a hydraulic cylinder, therefore, horizontal drilling on the wall of the steel sleeve, the layer of cementand the lithosphere can be completed through one time of going down, efficiency of the down-hole horizontal drilling can be improved greatly the power source provides power to the executing mechanism through an oil conduit, the oil conduit and a sealing connecting component are well sealed, and special sealing of a motor, a battery and electrical wires is not necessary. The earth oil down-hole drilling device has a simple structure, convenient operations and low cost.
