摘要
南堡地区是冀东油田近年来非常重要的产区,主要生产层位是东营组和沙河街组。为解决该地区单一地质录井难以判别油水层问题,通过统计古近系的气测资料和试油资料,分析多口已试油井的气测全烃、烃组分、峰基比及派生参数特征,优选两组气测参数C_1/C_3-W_h、W_h-C_2/C_3,建立了适合于南堡地区的气测解释图板和解释标准,进一步将气测录井与三维定量荧光录井相结合,建立了适合该区的峰基比-三维定量荧光对比级别解释图板和解释标准。应用两种方法进行该地区58口井现场综合解释,其中已试油26层,符合21层,综合解释符合率达到80%以上。该方法较好地解决了该地区储集层物性差、四性关系不明显的油水层识别难题。
Nanpu Area is a very important oil producing area in Jidong Oilfield in recent years,the major productive series are formations of Dongying and Shahejie.In order to solve the identification of oil and water layers with single geological logging in this area,through summing up Paleogene gas log-ging and well testing data in Nanpu area,analyzing gas logging total hydrocarbon,hydrocarbon compoments,peak-tobase ratio and derived parameter features of formation tested wells,optimizing two sets of gas parameters between C1/C3 and Wh,Wh and C2/C3,gas logging interpretation charts and interpretation criteria suitable for Nanpu Area were established.The combination of gas logging and three-dimensional quantitative fluorescence logging was used to establish the interpretation chart and standards for peak-to-base ratio and contrast level of 3-D quantitative fluorescence.Two methods were applied to the field comprehensive interpretation for 58 wells in the area,which had been tested 26 layers and accorded with 21 layers.The comprehensive interpretation coincidence rate was above 80%.The method can be uesd to solve the problem of identifying oil and water layers with poor reservoir physical property and unobvious fourproperty relationship in the area.
