main idea: plate tectonic provides the condition of generation of oil and gas, works for geologic paths and as "pressure cooker" for them.
p1.plate tectonic is key for formation of and finding of oil and gas
- top 4 reservoir places of oil and gas are river deltas, continental margins offshore , desert and arctic area
p2. conditions for oil and gas formation
-conditions: anoxic, rapid buried microorganism
-new developing ocean basins: water flows - organic-rich constricted water circulation - less oxygen
-2 eg.
p3. words for geologic paths
- continent drifting and collision provide movement from rivers to desert and poles
-eg: information suggested that it belonged to another end of land
p4. works as "pressure cooker" that mature the organics into oil and gas
- release the oil and gas from deep layer
-trap them in the sediment instead of releasing them directly onto the surface
- oil and gas fileds form
new words:
subduction: 俯冲,减少
unmistakable: 确定无疑的
plate tectonics: 板块构造论
alternatively: 或者
arctic: 极寒的 |
