试述生储盖组合的类型及形成大型油气藏必须具备的生储盖组合条件。

答案

参考答案:

根据生、储层在时间和空间上的分布和接触关系,可将生储盖组合分为两大类:连续的或相邻的生储盖组合、不连续的或间断的生储盖组合。

连续的生储盖组合包括:面接触,包括上覆式、下伏式、互层式;带接触(也称侧变式或指状交叉式);体接触(也称封闭式或透镜式)。

不连续生储盖组合可分为不整合型生储盖组合和断裂型生储盖组合。

在实际情况下,单一型式的生储盖组合往往很局限,输导油气的能力也有限,而更多的是多种型式联合形成复合的输导网络,因此,复合型的生储盖组合对大型油气藏的形成更为有利。

有利生储盖组合要求三者在时、空上配置恰当,有良好的输导层,使烃源层生成的油气能及时地运移到储集层聚集,盖层的质量和厚度能确保油气不致于散失。

Nearly two decades has passed, I still remember my favourite professor, James Sehwartz. Whenever he smiles, it’s as if you’d just been told the funniest joke on earth. Almost all his students are his friends, and almost all his students know his life story.
When James was a teenager, his father   36  him to a fur factory where he worked . This was during the Great Depression. The   37  was to get James a job.
James entered the factory, and immediately felt as if the   38  had closed in around him. The room was dark and hot, the windows covered with dust, and the   39  were packed tightly together, running like trains. The fur hairs were flying,   40  a thickened air, and the workers,   41  the pieces of fur together, were bent over their needles   42  the boss marched up and down the rows, searching for them to go faster .James could hardly   43 . He stood next to his father, frozen with fear, hoping the boss wouldn’t   44  at him, too.
During lunch break, his father took James to the boss and pushed him in front of him,   45 if there was any work for his son. But   46  there was hardly enough   47  for the adult labours, for no one would give it up once he took a job.
Thus, for James, it was a   48 . He hated the place. He made a   49  that he kept to the end of his life: he would never do any work that brought   50  to someone else, and he would never allow himself to   51  money off the seat of others.
“What will you do?” his mother, Eva, would ask him.
“I don’t know,” he   52  say. He ruled out law, because he didn’t like   53 , and he ruled out medicine, because he couldn’t take the   54  of blood.
“What will you do?”
  55 , my best professor I ever had became—he thought it was the job not to hurt anybody.
