| 1 | The Experimental Research for the Pulverized Coal Combustion accompanied with the Oil Gas. | |
| 2 | So, reinjection of the associated gas is a method of EOR worthy for exploring. | |
| 3 | The desulfurization process of the oil gas and its improvement measures were introduced. | |
| 4 | Otherwise, a large amount of associated gas will be produced in the process of oilfield development, which will provide enough gas source. | |
| 5 | The single effect unit can be used as a refrigerator, on the other hand, its afterheat can be used to heat the petroleum gas. |
