定北地区盒1段致密砂岩气层测井识别与评价研究

Logging identification and evaluation of tight sandstone gas reservoirs of 1~(st) member of Xiashihezi formation in Dingbei area

  • 摘要: 为有效、精确地识别和评价致密砂岩气层,在地质条件约束下,通过储层"四性"关系研究,分析了定北地区盒1段致密砂岩储层岩性、物性、电性和含气性的相互关系及其对应测井曲线的响应特征。分析认为,盒1段致密砂岩储层岩性、粒度和孔隙结构是储层物性和含气性的主要影响因素,储层具有岩性控制物性、物性控制含气性的特征。运用交会图版法和三孔隙度组合识别法对盒1段气层进行了综合识别,将气层划分为三类,并进行了综合评价。

     

    Abstract: In order to effectively and accurately identify and evaluate the tight sandstone gas reservoirs, constrained by the geological conditions, through the ‘four properties' relation analysis, the lithology, physical property, electric property and gas-bearing property between the corresponding well logging response characteristics of the curve to tight sandstone gas reservoir of in 1~(st) member of Xiashihezi formation in Dingbei area was analyzed. The results indicated the lithology, the granularity and the pore structure were the main influencing factors of reservoir properties and the gas bearing property, the lithology controlled the properties and the physical properties controlled the hydrocarbon content. By using SEC engraving method and three porosity combination method, the comprehensive logging identification and the evaluation of tight sandstone gas reservoir in 1~(st) member of Xiashihezi formation were carried out, and the gas reservoirs were divided into three categories.
