蒙特卡罗数值模拟在多层管柱流体识别中的应用
Application of Monte Carlo numerical simulation in fluid identification of multi-layer tubing strings
摘要
Abstract
As a core technology in oil and gas reservoir development,pulsed neutron logging provides information on remaining oil and gas saturation behind casing,offering critical data support for potential tapping and efficiency enhancement of old wells,optimization of development schemes,and stimulation treatments.Aiming at two major challenges in practical applications—difficulty in fluid identification in the annulus and unclear fluid distribution within the tubing string—Monte Carlo numerical simulation is applied to establish a theoretical fluid identification chart,realizing accurate identification of wellbore and annulus fluid types.Field applications show that this method performs excellently in the interpretation of condensate gas reservoirs lacking profile logging data,provides reliable technical support for the late-stage development of high-water-cut oil and gas fields,and improves the effectiveness of oil and gas reservoir development.关键词
