Description

In Part I and II of this paper, the writer discussed the migrations and accumulations of natural gases from the angles of the characteristics of gases and waters and the formation pressures.<br> Part III deals with the mode of occurrences of gases in Higashi-Niigata and Shiunji gas field.<br> From these considerations, the writer comes to the following conclusions for the migrations and accumulations of natural gases in Niigata Prefecture.<br> 1. As expressed in isopachous map of each formation, the frameworks of sedimentary basins and modes of tectonic movements of basement seem to be different in each formation.<br> 2. By the modes of tectonic movements, occurrences of formations, supplying origins of sediments and sedimentary environments are controlled, and as a result, the characteristics of gas and water and tendencies of formation pressures have close relationships with formations.<br> 3. The writer presumes that in comparatively early stage after sedimentation, the genesis, migration and accumulation of natural gas virtually end, the reasons are (1) the characteristics of gases are different in each formation, (2) accumulations of gases are usually observed at the synchronous high areas of each formation.
