Possibilities of cross-hole a seismoacoustic tomography method for studying tightness a tire-cover of a reservoir underground storehouse of gas (USG), created in water-bearing horizont. Research cross-hole spaces for definition zones possible migration and accumulation gas outside of a trap are considered. The system of supervision used at carrying out cross-hole seismoacoustic tomography is proved, the example of revealing zones migration and accumulation gas outside from reservoir is resulted. Prospects application the given method on USG in a monitoring mode are defined.
Look into the possibility neutron method geophysical logging for determination zones of cavity nearwell areas gas reservoirs and determine the filler cavities. Relevant practicability using these methods on underground gas storage. Give an example these research on model and real conditions.
