Application of horizontal well in improving development effect of buried hill reservoir

Li Yinghuan (Research Institute of Exploration and Development, Liaohe Oilfield Company, CNPC, Panjin 124010, China)  
Block Shen 223-628 is a fractured buried hill reservoir in Jinganbao Oilfield of Liaohe Area. In view of the great drilling difficulty of buried hill reservoir and the poor development effect in vertical well, the exploring and research of horizontal well development is carried out. We optimized the azimuth, the vertical position and the length of horizontal section in reservoir. The practice has proved that it is feasible to develop the buried hill reservoirs with horizontal well so long as the design is reasonable, which has obtained the obvious effects in the respect of enhancing the development well productivity. That has an important guiding meaning to develop the analogous buried hill reservoirs.
