PLUG AND PERFORATE USING CASING PROFILES |
摘要 |
<p>In order to overcome the need to remove each fracturing plug after a plug and perforate operation it is desirable to utilize a profile latch in conjunction with a coupling profile. By having a profile in each coupling or at least in predetermined couplings a tool such as a perforating assembly including a fracturing plug may be precisely placed. A profile in the couplings also provides a means to latch the perforating assembly or other tool securely to the casing without using slips. Such profiles typically provide for securing the tool or perforating assembly in one direction although a particular profile may secure the assembly in place in two directions. By securing the tool or perforating assembly in one direction only the tool may be easily relocated or removed from the casing.</p> |
