龙26－平25长水平段水平井钻井技术
Drilling Technology of L26 -P25 Horizontal Well with Long Horizontal Section
摘要
Abstract
In order to develop the low permeability reservoir, the horizontal well with L26-P25 long horizontal section was deployed in Long 26 block of Daqing oil field.Based on the introduction of casing program and design features of well traj-ectory profile, the difficulties in drilling construction are analyzed and the technical measures adopted in this well are elabo-rated in detail in well trajectory control, rotary geo-steering drilling technology, friction and torque monitoring, hole clean-ing and some other aspects.L26-P25 long well is 4045.00m in total depth and 2033.00m in horizontal section;all the in-dexes meet the design requirements.It is a record of the longest horizontal section in horizontal well with water-base drilling fluid in Daqing oilfield, the construction experience is accumulated for the same type horizontal well with long horizontal section in future.关键词
