This something is called well completion. 在经过巨大努力完成了油藏相关物理参数的测定，并钻至设计井深之后，油井仍然还不能用于生产，因为原油不会自动地从所钻井筒的外面流入井筒。在钻井与油气井生产之间还有一些事情需要完成，这些事情就叫做完井。 INTRODUCTION Unit 6 Well Completion Since well completion is as important as drilling ,one needs to know the specific steps involved in the completion ,which has received elaborate description in the coming passage.
