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。

Results show that pressure,film thickness and temperature are changed with variation of the entrainment velocity;film profiles featuring a dimple can be formed in the contact zone when the entrainment velocity exceeds a certain level;t.
结果表明:卷吸速度的变化会引起油膜压力、膜厚和温度的变化;当卷吸速度变化到一定值时,在接触区会产生油膜的凹陷;凹陷的产生可用“温度-粘度楔”机制解释。
