The evolution of the paleo-hydrodynamic field was studied by using the method of sedimentary-water-head and the changing patterns of the present hydrodynamic field as determined from measured pressure data. The results show that the evolution of the hydrodynamic field is one of inheritance and that it controls hydrocarbon accumulation. The deposition center in the southeast of the depression is always a high-value zone for water-head and a dynamic- source zone of the hydrodynamic field. The slope zone in the northwest of the depression is always a low-value zone for water-head and is the main discharge area for groundwater; this is the hydrocarbon accumulation zone. Hydrocarbon accumulation is controlled by the hydrodynamic field. The reservoir shows a ring-shaped horizontal pattern. Accumulation occurs in a pressure equilibrium zone at the frontal surface between sedimentary water and infiltrating water. The hydrocarbon accumulations occur in two vertically different discharge units, Eh31 and Eh32, under the action of overpressure.展开更多

Emissions from the evaporation and combustion of these fuels contribute to a range of environmental and health problems, causing poor air quality and emitting greenhouse gases that contribute to global warming. Alternative fuel created from domestic sources has been proposed as a solution to these problems, and many fuels are being developed based on biomass and other renewable sources. Natural State Research, Inc. proposes a different alternative hydrocarbon fuel which is produced from abundant waste plastic materials. This fuel burns more efficiently and cleaner than commercial gasoline and diesel. The process exists to efficiently convert waste plastic into a reliable low cost source of fuel.展开更多
