recovery of core

The recovery of CO _ 2 injection core displacement is 48.15 % at 22.64 MPa.

芳48断块岩心在22.64MPa下注CO_2采收率为48.15%.

The coring tool is tripped in 26 times, with total coring footages of 205. 71m, recovered core of 168.29m and the average core recovery of 81.81%, the highest in the block.

共下取心工具26次，取心总进尺205.71m，收获岩心168，29m，平均收获率81.81%，达到该区块取心收获率的最高点。

The crease recovery of cotton/ bicomponent fabric is close to cotton/ XLA core fabric and better than cotton/ spandex core fabric.

棉/双组份短纤织物的折皱回复性能良好，与棉/XLA包芯织物相近，优于棉氨包芯织物。

The result shows that the sulfonate system can be used to effectively reduce the injection pressure and raise the efficiency of steam drive and core recovery ratio.

研究结果表明，石油磺酸盐体系可有效降低蒸汽注入压力，提高驱替效率和岩心采收率。
