摘要：吉林大情字井油田二氧化碳试验区全部为笼统注气。为准确求取小层吸人量，开展了注气试验区的吸气剖面资料与地质参数的相关性研究。结果表明：多层低渗砂岩储层分层的相对吸人量与储层厚度具有明显的正相关性，特定条件下与储层物性具有一定的正相关性，且各小层吸气量动态变化幅度非常小；大情字井油田青，段储层的吸气物性下限为孔隙度8.6%；形成了储层厚度与相对吸气量的3种线性关系。研究成果对类似的CO，注人区具有一定的参考意义。

Abstract: There is all commingled CO, injection in the testing block of Jilin Daqingzi Oilfield. In order to accu rately obtain the intake amount of the sublayers, the correlation researches between the gas injection profile data and geological parameters were conducted in the test area. The achievements show that there is obvious positive cor-relation between the relative intake volume of the individual layer and thickness for the multi-layer low-permeability sandstone reservoirs, under the specific condition, so is a certain positive correlations with the reservoir physical properties, and moreover the changed degrees of the intake performances are pretty lower; the lower gas-injectivity limit of Member Qing-1 reservoir is 8. 6% ; there are three linear relationships between the thickness and relative in-take volume. The achievements possess certain reference significances for the similar CO, injecting block.
