摘　　要：肯基亚克油田目前处于开发中后期,水淹情况严重,剩余油挖潜不够充分。目前脉冲中子-中子测井(PNN)已在该油田测量了50余口井,在确定单井的剩余油分布情况、封堵高含水层以及二次解释、重新发现新的含油气储层等方面,整体效果较好,但对于物性较差的储层识别能力不强。在不同孔隙度条件下,对PNN识别储层的水淹情况进行分析,得出在该油田地层水矿化度条件下,为得到定量结论 PNN测井所需要的最低储层孔隙度以及分析方法;并且通过区域地层特征统计、经验公式等确定该油田PNN测井资料解释的相关参数。将解释成果与实际生产情况进行了对比,取得了较好的应用效果。Kenkiyak oilfield is in the afternoon of development life, water flooding seriously, and using the remaining oil is not enough. Nowadays, PNN（Pusle Neutron Neutron）logging technology has been logged more than 50 wells in this field. It has good overall application in determining the distribution of remaining oil in a single well, finding the high water cut layer and the new oil and gas reservoir, secondary log data interpretation, but it has little effect on recognizing flooded zone in poor reservoir. Based on analysis of flooding level identified by PNN technology under different porosity conditions, minimum porosity and analysis methods are obtained in this article. This minimum porosity is needed in PNN logging technology to obtain quantitative interpretation result. With statistics of regional layer characteristics and empirical formulas, PNN interpretation parameters are determined. Finally, comparing the interpretation result with actual production, good application effect is achieved.
