冷家油田是辽河油区水平井推广应用的主力地区。该油田储层属于中高孔隙度-高渗透率油藏,长期开发,油层亏空严重,在水平井钻井施工中易出现井漏等复杂情况。通过现场研究,摸索总结了水平井防漏堵漏工艺技术,有效减少了井下复杂情况,缩短钻井周期,取得了很好的效果。
Lengjia Oilfield is the main area where the horizontal wells in Liaohe Oilfield are popularized and applied. The reservoir belongs to medium-high porosity and high permeability reservoirs. It has been developed for a long period of time. There are serious deficits in oil reservoirs and prone to well leakage in horizontal well drilling. Through on-the-spot research, this paper explores and summarizes the technology of horizontal well leakage prevention and plugging, effectively reduces the complicated situation in the underground, shortens the drilling cycle and achieves good results.
