摘要

以取心井的岩石薄片、扫描电镜、物性、毛管压力曲线等资料为基础，结合储层物性测井参数解释结果，对塔南油田塔19-3、19-17区块查干组储层从沉积特征、储层展布、物性特征、岩性特征、孔隙类型及孔隙结构、主控因素等方面进行分析与评价，认为该储层为一套低

孔低渗储层，其物性特征主要受沉积微相及成岩作用控制，主要发育于研究区的中北部和中东部地区。综合储层的岩性、物性、成岩后生作用和孔隙结构等特征，对塔19-3、19-17区块查干组储层进行分类，将其划分为Ⅰ（好）、Ⅱ（中）、Ⅲ（差）、Ⅳ（极差）四大类，区内主要发育Ⅱ、Ⅲ类储层。

Abstract

The sedimentary characteristics, distribution, physical
property, pore type, pore structure, and the master control
factors of the reservoir are roundly evaluated by combining
with the result of well log interpretation based on the rock
section, SEM, physical property, lithologic features, CP curve.
This reservoir is a set of low-porosity and low-permeability
reservoirs, and its physical property is controlled by
sedimentary facies and diagenesis. Most of the reservoirs
develop in the north and east of the center of the Tanan
Oilfield. Based on the above analysis, we divide the reservoir
into four types. They are type I, type II, type III, type V, and
most of the reservoirs are the type II and type III in this area
