摘要:针对利用测井资料对地层进行划分与对比在划分细层时存在的弊端,采用煤层标志层法、等厚度法、测井曲线特征法和沉积旋回分析法,对地层进行了精细的划分与对比。前人对该地区的地层未展开过精细研究,通过测井资料、延安组煤层和炭质泥岩标志层、沉积旋回、等厚法等对研究区160口井进行了分析研究,将延安组延9油层组的地层自上而下划分为3个小层,分别是延9,、延9,和延 93。又将延9,划分为延9、延9和延9,三个单砂体,将延9,精细划分为延9,和延9两个单砂体。延9油层组的精细化分与对比为后期沉积相、砂体展布、储层特征及有利区块的预测提供了基础地质资料,具有重要的意义。

Abstract; Aimed at the shortcomings of the classification strata by using the logging data and the problems of the fine classification stra ta,by adopting the methods of marker beds,sedimentary cycle,equal thickness method and so on,the fine stratigraphic classification and correlation of Yan 9 oil-bearing formation in Yang 57 Distriet of Suijing Oilfield was carried out. The strata of the area have not been studied in detail,by means of logging data, Yan'an Formation coal beds and carbonaceous mudstone marker beds,sedimentary cycle,E-qual thickness method and so on, analysis of 160 wells in the study area,from top to bottom, Yan 9 oil bearing fomation can be divid-ed into three small layers, such as Yan 9, , Yan 9, and Yan 9,. On the hand, Yan 9, can be divided into Yan 9' , Yan 9; and Yan 9, three single sand body, Yan 9, is divided into two single sand body, such as Yan 9, and Yan 9;. The fine elassification and correlation can provide geologic basic data for the study on sedimentary facies,sand body distribution,reservoir characteristics and the prediction of the zone, which have an important significance.
Keywords; Suijing Oilfield; Yan 9 oil-bearing formation ;stratigraphic classification and correlation;oil reservoir
0引言
利用测井资料对地层进行划分与对比是前人对地层划分的主要方法之一,还有一些学者是根据野外露头资料进行地层的划分,但是这种方法在划分细层的时候存在一定的弊端。以前很多学者在研究地层的时候,应用的方法较单一,结果一般划分到小层,对于细层划分较少。本文在前人研究的基础上,
主要应用煤层标志层法、等厚度法、测井曲线特征法和沉积旋回分析法的综合研究,对该区的地层进行了精细的划分与对比(12)。
精细地层划分与对比是所有油气藏工作重要的基础,随着油气藏的不断开发,以前的地层划分与对比已经不能满足绥靖油田延9油层组目前的勘探与开发的需求,需要通过精细地层划分与对比,明确单砂体划分标准,在此基础上开展小层对比、微构造、
