冷家油田储层成岩作用及对孔隙演化的影响

Diagenesis and Its Effects on Pore Evolution of the Reservoir in Lengjia Oil Field

利用各种分析化验手段研究了辽河冷家油田冷43断块稠油油藏S1+2段砂砾岩储层的成岩作用特征，建立了储层的成岩演化模式，研究了储层的孔隙类型，定量分析了储层成岩作用对储层孔隙演化的影响，为冷43断块油藏描述提供了成岩模型和孔隙演化模型。

The paper studies the diagenesis of glutinite reservoir of S1+2 members of heavy oil pool of Leng 43 Fault Block, Lengjia Oilfield. The model of diagenetic evolution is established. The pore types of the reservoir are discussed and the effects of diagenesis on the pore evolution are analyzed quantitatively. The models of diagenesis and pore evolution have been provided for the reservoir description of Leng 43 Fault Block.
