early production period meaning in English

开采初期

It is suggested that because the volcanic reservoir has very high heterogeneity , waterflooding process should not be adopted rashly in the early production period until obtaining experiences from clustered - well lest : infill drilling and adjustment during the period of early production may enhance producing extent , prolong water - free oil production period and improve performance response : a number of horizontal wells drilled during the mid - period of production may further increase the single well productivity and keep relatively long - term production stable and high
指出，由于火山岩储集层非均质性极强，在火山岩油藏开发初期切不可贸然采用注水开发，应在实验井组中取得经验后，方可逐步推广；开发初期，实施加密井调整措施，可提高储集层动用程度，延长油藏无水开采期，改善开发效果；开发中期钻一定数量的水平井，可进一步提高单井产能，使油藏保持较长期的稳产、高产。
