Embodiment Construction

[0043] see Figure 1 to Figure 6 , the first embodiment of the present invention is provided in the form of a rod assembly, specifically a sucker rod 100 comprising a male connection end 10 and a female connection end 20 . A plurality of sucker rods 100, such as a first sucker rod 100A, can be achieved by connecting the male connection end 10 of the first sucker rod 100A to the female connection end 20 of another sucker rod (such as a second sucker rod 100B) or matched to connect the second sucker rod 100B in series. The male connection end 10 includes a generally cylindrical male connection portion 12 matingly received in a cavity 22 to engage the male connection end 10 of the sucker rod 100A with the female connection end 20 of the sucker rod 100B. The male connection part 12 is provided with a plurality of engagement ribs in the form of splines 14 extending in the direction of the longitudinal axis of the rod 100 . The cavity 22 in the female connector 20 is provided in t...

Abstract

A coupling assembly for coupling a first rod member with a second rod member, the assembly comprising a male connecting end of the first rod member being adapted for being received into a female connecting end of the second rod member; and a locking mechanism for preventing the first and second rod members from being uncoupled, the locking mechanism comprising a stop positioned in between the maleconnecting end and a locking member such that during use the locking member engages at least a part of the female connecting end and the stop thereby preventing the male connecting end from being withdrawn from the female connecting end.

Description

technical field [0001] The present disclosure relates to an assembly for connecting together rods or rod sections, such as sucker rods, and in particular to applications in the oil and gas industry. Background technique [0002] The present disclosure finds particular, but not exclusive use in applications having rotating sucker rod strings. Accordingly, the present disclosure will be discussed in connection with issues associated with rotating a sucker rod string, particularly the application of high torques to a sucker rod string used downhole in the oil and gas industry. [0003] Subterranean deposits of coal contain large amounts of methane gas entrained in the deposits of coal. To date, there have been significant obstacles to the widespread exploitation and utilization of methane gas deposits in coal seams. The most important issue is that coal seams, while they may extend over thousands of acres, are usually quite shallow, ranging from a few inches to a few meters. ...
