An automatic vertical drilling tool

Abstract

The invention discloses an automatic vertical well drilling tool. An upper support suspension frame unit, an upper power unit, a measuring controlling storage unit, a lower power unit, a lower supporting suspension frame unit and an executing unit are arranged in an inner cavity of a tool outer cylinder from top to bottom in sequence. Before going down, a programmed control program is input into a circuit board of the measuring controlling storage unit, when a rotating disc drives the tool to rotate for working, rotating and stabilizing of a torque shaft are directly controlled through the lower power unit, accordingly, opening and closing functions of a flow channel are achieved, when the tool rotates to a high side (an upper well wall position), three executing pistons of the executing unit extend out under the effect of sludge pressure, telescopic executing palms connected to the executing pistons are pushed to the high side (the upper well wall), accordingly, a drilling head is forced to cut a low side (a lower well wall) powerfully, and the function instructions of drilling, entering and deviation rectifying at the same time are completed.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery and equipment, and relates to an automatic vertical drilling tool. Background technique [0002] With the continuous expansion and deepening of the field of petroleum exploration and development, the workload of exploration and development of high-steep structures and strata with large dip angles in the piedmont is increasing. key. [0003] Many foreign companies have successfully researched and applied anti-deviation and straightening automatic vertical drilling tools in the field, namely the Verti-Trak system of the American Baker Hughes company and the ZBE2 / 3 / 4 / 5000 system of the German Smart Drilling company. The development of vertical drilling tools is relatively mature, but the disadvantage is that the solenoid valves, hydraulic cylinders and other components of the system are easy to wear and get stuck, resulting in system failure and prone to sticking. [0004] Most of the p...
