摘　　要：针对气井在生产时受邻井影响,测试所得压力并非真实地层压力的问题,提出了邻井影响下地层压力求取的方法。采用井间干扰理论,即多井同时工作时,地层中各点的压力降应当是各井单独工作时在该点造成的压降的叠加和。通过计算测试井周围各个邻井在该井产生的压降叠加和,从而确定该井真实的地层压力。结果表明,通过该方法计算的地层压力能准确地反映地层特征,为油气田稳定运行生产奠定基础。The reality of the formation pressure directly impacts on the effect of the gas reservoirs.Influenced by the adjacent wells,production test pressure obtained in gas wells is not a true formation pressure.In this paper,filed analysis of the test data,the use of well interference theory,the pressure correction are obtained at a more realistic formation pressure,it provides foundation for the stable operation of the production of oil and gas fields.
