查询词典 aromatic hydrocarbon

Consider to think, although apparent gaseous state is not had in 0 derv of the interfuse in artesian well fluid,hydrocarbon exists, but fall in certain environmental temperature condition, the volatilization with have certain free hydrocarbon composition appears C_(11 the following liquid state volatilizes hydrocarbon , what cause gas to measure complete hydrocarbon thereby is unusual, but the change that this won't cause gas to measure constituent to be worth however, use this one characteristic, can lift with complete hydrocarbon and the method with not elevatory firedamp will distinguish the complete hydrocarbon holiday that mixes fluid of derv artesian well to cause is unusual.

探究认为，虽然钻井液中混入的零号柴油中并无明显的气态烃存在，但在一定的环境温度条件下，将有一定的挥发游离烃成分出现C_(11以后的液态挥发烃，从而引起气测全烃的异常，但这却不会引起气测组分值的变化，利用这一特征，就可以用全烃升高而甲烷不升高的办法来区分混柴油钻井液引起的全烃假异常。
