摘要
为解决新疆玛湖油田低孔隙度、低渗透率储集层录井油气水解释难点,提高录井解释符合率,利用数据统计分析、交会图等技术,通过提取气测、岩石热解流体识别敏感参数,建立了气测含油指数K_(oq)与烃相系数U_h解释图板、岩石热解轻重比R_(L-H)与岩石热解含油指数K_(od)解释图板,将两种图板结合使用,在该区近两年新钻井中进行应用,录井解释符合率由51.4%提高至76.2%,应用效果较好,可为该区低孔隙度、低渗透率储集层流体判别提供新思路。
In order to solve the mud logging difficulty of oil,gas and water interpretation in low porosity and low permeability reservoirs in Mahu Oilfield,Xinjiang,and improve the coincidence rate of mud logging interpretation,the oil index Qzs and hydrocarbon phase coefficient Uh interpretation chart,and rock pyrolysis ratio of heavy to light Qzhb and parameter Dzs interpretation chart were established by extracting sensitive parameters of gas logging and rock pyrolysis fluid identification,they were used in the newly drilled wells in the past two years.Mud logging interpretation coincidence rate was increased from 51.4% to 76.2%.The application effect is good and it can provide a new idea for fluid discrimination of low porosity and low permeability reservoirs in this area.
