Abstract: Now the herringbone horizontal well technology has become an important approach to the production improvement in low-yield oilfields both at home and abroad and the secondary and tertiary oil recovery in old oilfields as well as the enhancement of economic performance of oilfield. To probe into the feasibility of developing low permeability thin reservoir in Daqing peripheral oilfields with the four-branch herringbone horizontal well technology, the Downhole Operation Division of Daqing Oilfield Company Limited took the trial area of Zhaozhou Oilfield as the study object, carried out well pattern and well trajectory parameter optimization study, designed and implemented drilling of Zhou 72-Ping 54Z herringbone horizontal well under the guidance of fine geosteering technical scheme for horizontal well drilling, and obtained good drilling results. Practical results show that to develop the herringbone horizontal well technology is feasible in low permeability thin reservoir in Daqing peripheral oilfields.
