摘要
国外特别是苏联对煤成气的研究成就突出,煤成气的勘探效果显著。认为含煤盆地中有两套成气岩性(煤层和含分散有机质泥岩),在盆地沉积变质过程中存在两个成气高峰期。在天然气聚集规律方面认为,区域断裂特别是掩冲断裂带有利于天然气的运移和聚集。黑龙江东部含煤盆地含有机质丰富、冲断层发育,地质条件有利于天然气的形成和聚集,是寻找天然气资源的有利地区。
ABSTRACT
Recently, investigation and exploration of coalbed gas have achieved great
successes in foreign countries, particularly in the Soviet Union. it is known
that there are two suits of gas source rocks (such as coalbed and mudstone con-
tainig dispersive organic matters) and two gas generation peaks during the evol-
ution of basins. The regional faulled zones, particularly thrust fault zones, are
favourable for the migration and accumulation of natural gas. The abundant
organic matters, well-developed thrust faults and geolcgical sellings within the
coal-bearing basin in the East of Heilongjiang province provide favorable places
for prospecting gas resources.
