The key problems during the low permeable reservoir development are summarized based on the analyses of current development status and development theory and some directions such as increasing the reserves by rolling method, virgin reserves development, well spacing density adjustment, fine flooding, flooding pattern modification, and horizontal well development method. The development potential and technological strategy for low permeable reservoir in Binnan Oilfield such as systematic study of fine reserves description and remaining oil, crustal stress, crack description, small well spacing density are presented in this paper. Such technologies as deep reservoir forecasting technology, horizontal wells fracturing technology, high-pressure zone injection, refractory reserves development under the economy policy for lean grade reservoir and well spacing refinement and improvement to manipulate the oil zone control and development status are presented in this paper which aim at improving the development result of low permeable reservoir in Binnan Oilfield and increasing the ultimate recovery.
