Research on Developing and Employing Low Permeable Complex Broken Piece Reservoir of Dongzhuang Oilfield

Dongzhuang Oilfield owns low permeable complex broken piece reservoir, and it grows into 9 little broken pieces which contains small oil area and , 2,590,000 t petroleum geological reserves . The physical quality of its oilbearing layer is bad, the layer is deep and the nature of crude oil has the characteristics of two high and one low. Since reserves grade is low and it is difficult to develop, it has not been employedthough it has been discovered for more than 30 years.According to the geological characteristic of the oilfield, this paper studies the feasibility of its economic effective development, the adaptability of water flooding and development, well net and well distance, reasonable pressure level as well as single well producing capacity, and suggests the developing train of thought that oilfield can implement.
