| 摘 要： | 二连盆地是由众多早白垩世断陷湖盆群组成的大型陆相沉积煤、油共生盆地,含有丰富的煤层气资源。为了查明二连盆地煤层气分布特征和勘探潜力,首先,从区域地质背景和聚煤特征等方面分析了二连盆地煤层气成藏条件,并对各凹陷煤层气地质条件进行了分析对比和排队,优选出了11个煤层气勘探有利凹陷;其次,通过研究煤炭储量较大的白音华凹陷的煤层厚度、埋深、煤岩煤质特征、煤储层物性、煤层气保存条件和资源分布等因素,认为白音华凹陷煤层气成藏条件较好,并进一步指出该凹陷东部煤层厚度大、分布稳定、埋藏适中、煤层气富集且保存条件好,是今后首选的煤层气勘探目标。 |
| 关 键 词： | 二连盆地 凹陷 煤层气 勘探目标 |

| Abstract: | Erlian basin is a large-scale continental-facies sedimentation basin with coal and oil,formed of many small Early Cretaceous lake depressions,contains abundant coalbed gas resources.In order to find out distribution characteristics and exploration prospect of coalbed gas in Erlian basin,firstly,this paper researches coalbed gas forming-pool condition by analyzing regional geological background,feature of accumulating coalbed and so on,and selects 11 favorable depressions for coalbed gas exploration based on analyzing and contrasting all depression's coalbed gas geological condition;secondly,confirmes that Baiyinhua depression has splendiferous condition of coalbed gas enriching and forming-pool by researching coalbed thickness and depth,coal rock characteristics,reservoir properties,coalbed gas protecting condition and resource.Furthermore,authors point out that the east of Baiyinhua depression is favourable target for coalbed gas exploration in future with thick coal seams of extensive distribution,moderate depth,widespread gas display and good protecting-condition. |
| Keywords: | Erlian basin depression coalbed gas exploration target |
