试油资料在高含钙砂岩储层勘探中的应用

Application of High Cherished Calcium Sandstone at Westward in Store Layer Exploration.

针对大庆油田西部高泥、高钙砂岩储层特点,将酸化和压裂有机结合,可效改善油层的物性条件,可提高压裂效果和油井单井产能,为西部探区增加可采储量。在该区探井进行地层测试,对资料进行解释、评价油藏特征,可确定完井和试油方法,为酸化压裂提供选层依据。

According to the characteristics of high cherished mashed and calcium sandstone in store layer of Daqing oilfield, combining acidification and fracturing organically, the substance nature of oil layer can be improved effectively and the fracturing effect and the single oil well production can be increased at great extent so as to raise reservoir potential in westward explore area. Through conducting formation test to exploration well at the area, the method of well completion and test can be determined and a basis for choosing acid and fractured layer can be provided by interpreting the data, valuing oil pool character.
