Application of submerged pressure maintaining sealed coring techniques to Well Xushen-12;

Influencing factors and correction method for error of fluid saturation calculation during sealed coring;

First application of sealed coring technique in Bohai Oilfield

Based on the sealed coring, and combined with logging interpretation and numerical simulation, the water flooded characteristics of oil layer, and remaining oil distribution can be studied, the inherent relation of water flooded characteristic and interlayer, internal and plane heterogeneous characteristic, water flooded characteristic and fluid can be revealed.

Effect of degassing in sealing core drilling on the water saturation of cores;
