Abstract: A downhole coiled tubing latch for positive latching to a drill pipe while pumping fluids. The apparatus comprises a housing positioned in the drill pipe with a slidable mandrel positioned in the housing. The apparatus further comprises a latch stinger which can be lowered on a coiled tubing and sealingly engaged with the mandrel and the housing. When weight is set down, the stinger and mandrel are moved downwardly which actuates latch fingers on the mandrel which latchingly engage a groove on the stinger to positively hold the stinger in place while fluids are pumped therethrough. One or more pressure balance pistons are used to help hold the apparatus in a latched position when pressure is applied. When weight is picked up, a spring returns the mandrel to the unlatched position so that the stinger may be removed.
