Abstract:

Da NiuDi field is a lower permeability gas field. This paper calculates ultimate interwell distance and technical rational spacing between wells by different ways;on the base of the economic assessment method ascertain the rational spacing between wells in the field. Based on the study, we think that t it is reasonable that the technical rational spacing between wells is more than
the economical ultimate interwell distance. Then it has been put forward to deploy the close-spaced well in the relative high permeable bed to get high product produce, and to deploys the light-spaced well in the lower permeable bed to get good economic effect. Finally combining the study and the numerical simulation to ascertain the interwell distance in the high permeable bed is 1000m,the one is 1500m in the lower permeable bed.

Key words: low permeability, well spacing density, heterogeneous pattern well spacing
