Abstract

Discovery in water areas of the seas, oceans and some lakes of set of deposits of gas hydrates and their detection confinedness to areas with the raised values of geothermal fields have made a choice of criteria of search of the deposits most favourable to working out especially actual. Thereupon the author makes a number of the requirements, which performance at a choice gas hydrates deposits will allow to make gas production of it profitable. It is found out that to these conditions more all corresponds to a deposit of the hydrates generated by griffons functioning throughout a long time interval of operating underwater mud volcanoes. On the basis of calculations it is proved that thickness of layers of hydrates this deposits depends on volume of gas emissions of a griffon, and also depth of the sea on which there are griffons. The area of sedimentation of hydrates round a griffon at 20-50 time is less than flood area breccia during eruption also does not exceed first tens hectares. It is shown that process of thermal destruction hot breccia the rest which has generated for years of a volcano of a hydrated-clay layer does not change essentially volume-mass indicators of this layer
