Research on Optimization Method of Subtle Reservoir According to Sand Well

In this paper, in order to solve the problem of difficult development of the hidden reservoirs in the remaining unutilized reserves in Daqing and the low rate of production capacity, the research on individualized development and design has been carried out, and the high-efficiency development method of sanding wells has been proposed. On the basis of layer and fine oil and water identification, while ensuring the maximization of economic benefits and taking into account the demand of oilfield for production, the design and optimization of three technical problems of well type, well Pattern and development mode are mainly guided to guide the unusable hard-to-recover reserves in Daqing's excellent construction.
