Application of rapid drilling technique of “one trip drilling” in Lukeqin heavy oil reservoir

Lukeqin heavy oil reservoir is in great depth and developed with salt rocks,so the requirement for wellbore quality is high.Frequent tripping is the feature of the preexisting drilling process,and the drilling efficiency is low.Base on surveying a number of past field operations,the drilling history data is analyzed,and the matching speed raising technique is studied.The high efficient PDC bit and high efficiency BHA are designed and optimized,and the high quality matching drilling fluid is taken,to carry out the objective of two sections of drilling operations in one trip.The rapid drilling technique of one trip drilling improved greatly the drilling rate of Lukeqin heavy oil reservoir,and decreased the drilling cost.It effectively protected the reservoir,and played a great role in increasing oil reserve and production.
