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.
随着世界范围内水平井开发油气田越来越普遍，为提高水平井的产能，相应地对水平井的压裂施工越来越多。
With more and more using horizontal well to explore oil and gas field, to enhance the production capacity of horizontal Wells, there are more and more fracturing to horizontal Wells.
由于对重复压裂井原有裂缝失效程度的难以评价，重复压裂井的产能预测常常有很大的误差。
Prediction results of productivity of refracturing Wells often has large error because the effectiveness failure of the previous fractures in refracturing Wells is difficult to evaluate.
彩南油田九井区储层属于中孔特低渗储层，为了形成产能进行了整体压裂。
The reservoir in well block 9 is middle porosity and specially low permeability one, fracturing was implemented in order to builds up productivity.
