Evaluation Method of Pressure System in Putaohua Oilfield :A Case Study in the North of Pubei Area
摘要
Abstract
Aiming at the problem of reasonable formation pressure and reasonable flow pressure in low permeability oilfield , the variation law of formation pressure under different water cut ,recovery degree and injection‐production ratio was studied ,a new method for calculating reasonable formation pressure was established ,and the rational strat igraphic pressure range and the adjustment of pressure system in each block in Pubei area was obtained.Considering the effect of water content and liquid production on correcting the actual IPR curves of each fault block in Pubei area the reasonable flow pressure range of each fault block was calculated ,the correction equation of inflow performance under various connected conditions of single well in Pubei area was established ,and the reasonable flow pressure range of some single well was calculated.The results show that the evaluation method of formation pressure and flow pressure is more reasonable.According to the calculated minimum reasonable formation pressure and the minimum reasonable flow pressure of each fault block ,the oil increasing effect of the adjustment well is obvious and the formation pressure tends to be reasonable.The gas influences of the wells were well controlled and the pump efficiencies were improved by adjusting flow pressure.关键词
