小泵深抽技术在高气液比低产液井上的研究与应用

Applied study of depth-pumping with small diameter pump in high gas fluid ratio and low production wells

为实现深层低渗油气藏停喷井复产的目的,本文研究形成的小泵深抽配套技术是通过尽可能加大泵挂深度,排出井筒积液,实现油气井复产的一种有效技术手段,现场应用效果较好。

For the purpose of resuming the production of deep-layer low-permeability oil/gas wells,this paper studies thedepth-pumping technology with small diameter pump that is an effective method and can enlarge pump setting depth and drain offwellbore liquid loading as far as possible to resume the production of oil and gas wells. The field application proves that this technologyhas good effect.
