摘要

分析了歧口凹陷滨海台阶带沙河街组低阻油层的成因机理和测井响应特征，重点对油层砂体的分布特征进行了测井地质评价，提出了针对该低阻油层的测井地质综合评价方法，即采取井震资料相结合的方法对单砂层进行等时对比刻画，提出应用各项勘探技术追踪砂体，精细解释内幕层，以砂组为单元落实隐蔽圈闭，应用多种预测手段找出有利储集带，明确油藏规律，细化评价单元，进行老区整体复查、整体评价。

Abstract

We analyze the genetic mechanism of the low resistivity layer in the Shahejie Formation of coastal step in Qikou sag and describe its logging response characteristics. A method for the logging and geological comprehensive researching to the work area low resistivity layer is devised and its application suggests good effect. The method includes steps of comparable portraying of single sand body by combined well logging and seismic data, tracking sand bodies by the comprehensive application of exploration technologies, fine interpretation of inside layer, implementing the hidden sand trap with sandstone group as a unit, identifying favorable reservoirs by various forecasting means, clearing the reservoir accumulation rules, detailing the evaluation unit, and finally giving the overall review and the overall evaluation of the old exploited areas.

Key words： Low resistivity layer; Logging interpretation; Sandbodies comparison; Qikou sag.
