Abstract

The Y block reservoir in Ordos Basin is a typical low porosity and permeability tight sandstone reservoir with poor physical property and strong heterogeneity. On the plane, the small layer sand body Changes quickly, the continuity is poor, the pressure distribution is uneven, and the principal side effect is uneven. In the section, the liquid production in the stratification is not clear, the washing degree of the small layer is different, and the water contradiction in the multi-direction of the single layer is prominent. At present, the overall reservoir decline is fast, some Wells have low productivity and high water cut, and most of the Wells have more open layers. In this paper, based on geological factors and development dynamic factors, combined with fracture identification, the first development unit of Y block reservoir is divided, and on the basis of the first development unit division, the second development unit is further divided according to the situation of small layer division and correlation. The division of the secondary development units can correspond the development contradiction to the small layer, and has guiding significance for the evaluation of the subsequent reservoir development effect and the fine adjustment of development policy.
