摘要
Abstract
Gas cap reservoirs mainly rely on the expansion energy of the gas cap to extract the oil ring.The production of oil wells reduces the pressure of the oil ring and is easy to gas channeling,resulting in the loss of oil and gas resources.Considering reasonable exploitation of gas cap and realizing collaborative develop-ment of oil and gas,relevant development adaptability was conducted by using reservoir numerical simula-tion methods.Based on orthogonal experimental analysis,the main controlling factors affecting the develop-ment effect of gas cap reservoirs are gas cap index,condensate oil content,formation thickness,formation dip angle,and the ratio of vertical permeability to horizontal permeability.Through numerical simulation tests of different development methods under different geological conditions,the influence of various layer parameters on the development of gas cap reservoirs is analyzed.The results show that with the increase of gas cap index,the reasonable development mode gradually changes from depletion to water injection,and the development mode gradually changes from area water injection to barrier water injection with the increase of gas cap index.High condensate oil and high dip thickness reservoir should be developed by water injec-tion.关键词
