摘要/Abstract

摘要： 塔里木盆地英买35井区隔夹层分布规律不明，为后续油气勘探开发带来了困难。为了识别研究区隔夹层类型，分析其空间展布特征，结合取心、常规测井、化验分析及成像测井资料，明确了研究区主要发育隔夹层类型，采用三端元定型法分小层建立了隔夹层识别图版，提出了识别标准，分析了隔夹层的横向和纵向展布特征，研究了隔夹层对剩余油的控制作用。结果表明：研究区主要发育泥质隔夹层和物性隔夹层，在横向上，泥质隔夹层主要集中在目的层下部，连续性较好，而物性隔夹层则主要分布在中—上部，尽管厚度较小，但同样具有较好的横向连续性；在平面上，隔夹层主要集中发育于研究区中部，形成了较为明显的厚度聚集带，随着与中部区域距离的增大，隔夹层厚度向四周逐渐减小。受隔夹层空间分布控制作用，剩余油主要分布于研究区K3小层。

Abstract:

The distribution patterns of interlayers in the YM 35 well block of the Tarim Basin are unclear, which poses challenges for subsequent oil and gas exploration and development. To identify the interlayer types in the study area and analyze their spatial distribution characteristics, by integrating the data of cores, conventional logging, laboratory analysis, and imaging logging, the primary interlayer types in the study area were clarified. By using the three-end-member classification method, charts for identifying interlayers were established for sublayers, and identification criteria were proposed. The distribution of interlayers was analyzed laterally and vertically, and the controls of interlayers on remaining oil distribution were investigated. The results show that the study area primarily develops argillaceous interlayers and physical interlayers. Laterally, argillaceous interlayers are mainly concentrated in the lower part of the target layer, with good continuity, while physical interlayers are mainly distributed in the middle-upper part, with smaller thickness but good continuity. On plane, interlayers are mainly concentrated in the central part of the study area, forming a distinct thickness aggregation zone. The interlayer becomes thinner toward its margin as its distance from the central area increases. Controlled by the spatial distribution of interlayers, remaining oil is mainly distributed in the K3 sublayer.

Key words: Tarim Basin, YM 35 well block, argillaceous interlayer, physical interlayer, three-end-member classification method, spatial distribution, detailed evaluation, remaining oil
