1·Oil gas reserves is the premise that oil company bilks to run an activity in order to have production.
油气储量是石油企业赖以进行生产经营活动的前提。
2·Oil gas storage and transport systems are big arteries of the petroleum industry, while they may also be the causes of fire, explosion and pollution.
油气储运系统是石油工业的大动脉，另一方面又可能是火源、爆炸源和污染源。
3·The suitable time to clean oil tank and the safety problems such as oil gas poisoning, fire-explosion and tank deformation during cleaning operation are introduced.
介绍了油罐清洗作业中存在的油气中毒、火灾爆炸和罐体变形等安全问题，并针对问题提出了解决办法。
4·According to geologic model of unsteady groundwater flow in heterogeneous medium and adopting the finite difference solution, the direction and strength of oil gas migration can be quantified.
根据非均匀各向异性地层的非稳定的地下水流动模型，采用有限差分法求解，可以定量判断油气运移的方向及强度。
5·It is an important problem in reservoir estimation and oil gas exploration and development to predict lateral variation of reservoir parameters from seismic data and well log.
