因此,对水平井压裂后的试井和产能评价,以及压裂水平井的裂缝参数优化是一个十分重要的问题。
Hence, it is a very important problem to perform well test, evaluate the deliverability of the fractured horizontal well, and optimize the fracture parameters.
在对重复压裂井进行产能评价时,常常认为初次压裂形成的裂缝完全失效,这种考虑与实际情况是不相符合的,导致对重复压裂井的产能预测有很大的误差。
When estimating productivity of refractured well, the primary fracture is considered to be disabled and it is not coincident with actual facts and a great error of prediction result exists.
瓶颈裂缝可引起井产能急剧下降,压裂液滤失也对井动态有一定的负面影响。
The results indict that choked fracture and leak off of fracture fluid had a negative effect on well productivity.
