Abstract

The invention provides an impact type isotope releaser, and belongs to an isotope releasing device used in the logging process of an oil field water injection well. The impact type isotope releaser is composed of an upper half part and a lower half part, a rope cap on the upper half part is fixedly arranged on a rope cap connector, a switch control sleeve is connected with the lower portion of the rope cap connector, the switch control sleeve is sleeved with a first spring, and a locating pin above the first spring is fixedly arranged outside the switch control sleeve. A locking sleeve is arranged on the lower half part, a plurality of longitudinal cutting seams are arranged at the upper end of the locking sleeve, the locking sleeve is fixedly arranged at the upper end of an upper connector through threads, the lower end of the upper connector is connected with a water inlet chemical feeding opening connector, the lower end of the water inlet chemical feeding opening connector is connected with an isotope bin barrel, and a tapered valve with a sealing ring is arranged on the lower portion of a central transmission control connecting rod. The impact type isotope releaser is reasonable in structure and has the advantages of being high in release success rate, low in fault rate, reliable to use and the like, repeated logging construction is avoided, and time occupied by logging is reduced. The impact type isotope releaser can be used for releasing isotopes, and can also be used for releasing other similar tracer agents.

Description

technical field [0001] The invention provides an isotope release device used in well logging of water injection wells in oil fields, and is especially suitable for isotope release during well logging in high-pressure and low-permeability blocks. Background technique [0002] At present, during the construction of water absorption profile logging by storage logging tools, the releaser of tracers such as isotopes is an electric detonator, and the release time is controlled by an electronic circuit. After reaching the predetermined depth and waiting for the predetermined time, the electronic control device provides electric current to the electric detonator to explode to generate gas, push the releaser switch, open the releaser to release isotopes, and then the water absorption profile logging construction can be carried out. However, due to problems in the electric detonator itself or other reasons, the electric detonator cannot be exploded, and the releaser cannot be opened, ...
