摘　　要：建国以来，我国天然气勘探工作及储量增长情况总体上可以分为3个阶段：1975年以前基本上处于停滞阶段；1975～1989年为缓慢增长阶段；1990年以来进入了高速发展的阶段。20世纪70年代以来，我国天然气勘探的重大进展与对天然气聚集规律的认识和勘探思路的转变有着直接的联系。这些勘探思路的转变主要表现在5个方面：从油型气到以煤成气为主的多成因类型天然气的勘探；从构造圈闭到大面积岩性圈闭天然气勘探；从中浅层到深层天然气勘探；从常规天然气到非常规天然气勘探；从陆地到海洋天然气勘探。Since the New Republic of China came into being, natural gas exploration and gas reserves increase have experienced three main stages as a whole. Firstly before 1975 it was a blank age; secondly from 1975 to 1989 it was a slow growth age; and finally up till now there has always been on highly increasing development since 1990. Through looking back to the history of natural gas exploration, this paper pointed out that either great breakthroughs or new knowledge on gas accumulation have been achieved by the well-regulated exploration orientation. These helpful transformation in good time and good reason on exploration strategy could be outlined here as follows: (1) from oil-type gas to multi-genetic gases like CBM; (2) from the structural traps to large-area lithological traps; (3) from medium or shallow to deep plays; (4) from conventional to unconventional gas; (5) from land to sea.
