When the gas reserves of the gas cap are relatively bigger, the gas cap and the oil column should be exploited simultaneously. When the volume of the gas cap is relatively smaller and the energy of the edge and bottom water is sufficient, the oil column should be exploited first depending on the natural energy, then water injection should be done artificially, and the gas cap should be exploited at last.

By coordinate transformation,specifically,by using orthogonal coordinate system to obtain vertical high resolution ratio in superstratum water of Beibu Gulf and making use of Sigma coordinate system to match terrain in bottom water,the authors intend to set up Beibu Gulf Physical Oceanic Model and use the model to simulate partial tide M\-2,partial tide K\-1 and partial tide O\-1 respectively.

However, the water quality simulation results by CE-QUAL-W2 model revealed that the hydrologically induced density currents in winter together with the external loads of P were the main cause of the surface water quality deterioration, even though the bottom water carrying abundant P internal loads might be lifted to the middle layer by the water momentum force by the density current.
