Abstract
A method for accelerated break out of connected multi-segment tubulars by setting hydraulic fluid pressure to between 100 and 3000 psi, connecting the stationary wrench to a first segment of a multi-segment tubular, connecting a pivoting wrench to a second segment of the multi-segment tubular, and activating a pivoting hydraulic cylinder with a lever to break out the first segment from the second segment and wherein the pivoting wrench is configured to operate right side up and upside down for optimizing pivoting wrench flat fit.
Claims15
A method for accelerated break out of connected multi-segment tubulars, the method comprising:
- a. using an accelerated rod and sinker bar break out device with a support beam mounted in parallel to an installed pivoting hydraulic cylinder to prevent collapse of a base of the accelerated rod and sinker bar break out device;
- b. setting hydraulic fluid pressure in the accelerated rod and sinker bar break out device to between 100 and 3000 psi;
- c. connecting a stationary wrench of the accelerated rod and sinker bar break out device to a first segment of a connected multi-segment tubular;
- d. connecting a pivoting wrench of the accelerated rod and sinker bar break out device to a second segment of the connected multi-segment tubular;
- e. activating a pivoting hydraulic cylinder of the accelerated rod and sinker bar break out device using a lever to break out the first segment from the second segment, and wherein the pivoting wrench is configured to operate right side up and upside down for optimizing pivoting wrench flat fit;
- and wherein the stationary wrench extends at an angle of 90 degrees to a plane of the base.
A method for accelerated break out of connected multi-segment tubulars, the method comprising:
- a. receiving hydraulic fluid from a reservoir through an input port fluidly to a pivoting hydraulic cylinder;
- b. transferring the hydraulic fluid to the reservoir an output port from the pivoting hydraulic cylinder;
- c. bidirectionally flowing the hydraulic fluid to and from the first pivoting hydraulic cylinder port through a first bidirectional control port to and from the pivoting hydraulic cylinder;
- d. bidirectionally flowing the hydraulic fluid to and from the second pivoting hydraulic cylinder port through a second bidirectional control port to and from the pivoting hydraulic cylinder;
- e. using a lever engaging a manifold to change hydraulic fluid flow rates to and from the pivoting hydraulic cylinder;
- f. adjusting a primary pressure control valve to adjust hydraulic fluid pressure to and from the pivoting hydraulic cylinder, and
- g. affixing the first pivoting wrench to a first segment of a connected multi-segment tubular, and a stationary wrench to a second segment of a connected multi-segment tubular;
- and
- h. operating the hydraulic fluid to move the pivoting hydraulic cylinder to break out the first segment of a connected multi-segment tubular from the second segment of a connected multi-segment tubular.
