... and combined production by using horizontal-vertical wells is a feasible and effective way to improve further development effectiveness and the incremental recovery rate can reach to 5%. incremental oil production well pattern flooding residual oil simulation result reservoir oil layer modeling...

... are based on streamline numerical simulation method, are developed and discussed on the well pattern, well type, recovery rate, injection rate, injection cycle, etc. The result shows that design of well pattern plays a dominating role in the waterflooding, followed by the optimization of injection rate...

.... ②The static water body is about 5 times of hydrocarbon volume through geological evaluation, so the water drive energy is weak and has little effect on the field development. Thus the field can be developed in high recovery rate, and the reasonable recovery rate is around 4%. ③There is less interlayer...

... out and the main causes to form these problems are analyzed. According to the theoretical study and practical experiences, the main ways to develop the low permeability reservoir efficiently and economically are given. It is to raise the oil production, recovery rate and recovery factor on the basis...
