Abstract
Rational well patterns are essential for success of horizontal wells development in the field. This paper is aimed to provide a new multi-objective optimization method on injection-production patterns. The flow model of horizontal injection-production patterns is re-established based on reservoir fluid theory, while a new cumulative production function for horizontal patterns is derived by analyzing the deliverability fluctuation; an economic net present value ( NPV) function of petroleum development has been improved and applied in horizontal well patterns; the theory of wave frontal movement has been utilized to limit the pattern scope. From the synthesis of all the aspects mentioned above, multi-objective optimization model of horizontal injective-productive patterns is established with cumulative production and economic NPV as its target function, the control area and the pressure drawdown of patterns as its controlled conditions. The optimization method studied in this paper is finally applied in a certain field in O-man, and the results obtained from the method are verified to be valid by the reservoir numerical simulator. Compared with others, this method could be applied in horizontal well patterns and overall optimums could be obtained from the simultaneous optimization of engineering and economy. This study could make a theoretical support for project designs in reservoir engineering.关键词
