Abstract: The lens lithologic reservoir with low permeability is characterized by scattered distribution and strong heterogeneity of sand body. During the process of development,the core is seriously flooded and the water flooding effect in fan edge is poor. Therefore,based on the method and theory of reservoir engineering,the calculation methods of ring spacing of annular wells and well spacing of oil well were established,and the calculation chart was drawn. At the same time, the rational pattern well spacing for lens lithologic reservoir with low permeability was studied by numerical simulation method. The results show that the well pattern of core injection wing production based on the phase control residual oil can effectively alleviate the problem of water injection pressure in the form of square water injection well pattern,and then reduce the difficulty of water injection and improve the efficiency of water flooding. Compared with the positive well pattern,when the injection to producing well ratio is 1:2 in the cross annular well pattern of core injection wing production,the streamline distribution of the oil and water wells is more uniform,and the development effect is better. For the annular well pattern with the injection and production wells number of 3 and 6 or 4 and 8,when the ring distance is 200 m,the optimum well spacing of production wells is 300 m and 250 m,respectively. This study can provide a theoretical basis and reference for continuous and efficient development of lens lithologic reservoirs with low permeability.

Key words: low permeability lithologic reservoir, pattern well spacing, annular well pattern, numerical simulation, streamline distribution
