Abstract: In recent years,horizontal wells are applied to develop shallow fault reservoirs in Jidong Oilfield.The pay zone of the oilfield features in great horizontal length,unconsolidated formations,high hole deviation angle,and high liquid withdrawal rate.So the problems of sand control,lifting,sealing,and operating need to be solved to enable the oilfield to be put into operation successfully.This paper firstly researches the sand control technology and the hydraulic safety salvaging technology of sand control tubes in horizontal wells,as well as the completion technology of sand control tubes in horizontal wells and sidetracking horizontal wells,which tackles the problem of sand control during well completion.Secondly,it researches the production technology using special suck rod pump with high displacement applied to the vertical part of horizontal wells,and the autonomous grinding inclination correcting technology applied to the highly deviated part.Furthermore,it based on the hydraulic operation mode in horizontal sections and the safely salvaging mode in different sections,analyzes the assisted technology with single block,double blocks,and safety joints resistant to hydraulic pressure and solves varieties of sealing and salvaging problems in the horizontal wells of unconsolidated sandstones.These technologies have been successfully tested in the horizontal wells of Jidong Oilfield and have been widely applied and achieved remarkable results.
