大斜度井偏磨治理技术在桩西油田的应用
Application of eccentric wear of highly deviated well in Zhuangxi oilfield
-
摘要: 近几年桩西油田大斜度井数量增加较快,但开发过程中大斜度井杆管偏磨严重,为此开展了偏磨治理技术研究应用,通过应用小泵深抽井、大泵提海井、常规排量井防偏磨技术及配套工艺钻井,偏磨治理效果明显。Abstract: With the quickly increased number of highly deviated wells in Zhuangxi oilfield, the wear of rod string and tubing in pump well is continuously becoming serious. In this case, the study of eccentric wear has been put into practice. Through anti-eccentrically worn technology and matching drilling technology including depth-dumping well and other wells, obvious eccentric wear effect has been achieved.
