摘要
利用大港油田近5年PNN(脉冲中子-中子)测井技术指导明化镇-馆陶组浅层气开发措施显著井的测量数据,以及PSSL(脉冲中子全谱饱和度测井)技术在指导剩余油挖潜措施显著井的测井资料,开展PNN测井技术在长短源距计数率规范化处理后,长短源距计数率差和标准水层长源距计数率比值与声波时差数据间的关系研究,及PSSL技术在碳氧比、硅钙比测量值标准化处理后,碳氧比测量值和水线值差与硅钙比值间的关系研究。经过规律性统计分析,分别建立了PNN、PSSL测井技术以上参数间的交会图版,通过现场利用建立的交会图版,在指导浅层气开发、剩余油挖潜方面措施符合率达到85%以上,具有较高的准确度,对指导油气水井措施实施具有重要意义。
In the past five years,Pulsed Neutron-Neutron(PNN)logging technology and Pulsed Neutron Full Spectrum Saturation Logging(PSSL)have been effectively applied in Dagang Oilfield.They have achieved good results in shallow gas development of Minghuazhen-Guantao Formation and remaining oil recovery,respectively.Based on the data from the wells which have great results,this paper studies the relationship between the long-short space count rate difference,the standard water-level long space ratio and the slowness after the standardization of the long and short space counting rate of PNN logging,as well as the relationship between carbon/oxygen ratio,waterline value difference and silicon/calcium ratio after the standardized processing of carbon-oxygen ratio and silicon-calcium ratio measurement of PSSL technology.After regular statistical analysis,the cross plots of the above parameters of PNN and PSSL logging technology were established.The field application results show that the compliance rate of these plots in guiding shallow gas development and remaining oil recovery is more than 85%,which has high accuracy and is of great significance for guiding the development of oil,gas and water wells.
