Abstract

Abstract: In the study, through the large-scale core experiment, the pressure structure time-varying curve caused by the difference of the physical structure from the homogeneous core to the multi-level heterogeneous core nine-point well network to the row-like encryption is tested. Combined with the time-varying test results of three-dimensional oil saturation in core, the variation law and characteristics of water drive under the double influence of physical structure difference and pressure structure difference are studied in detail, including characteristics of flow field change and remaining oil distribution are discussed. The results show that from large homogenization to interlayer heterogeneity, the pressure of high permeability layer is moderate, the pressure drop is small, and the pressure drop of low permeability layer is large, and the pressure difference between layers is 3 MPa, high permeability layer and low. The degree of water flooding control in the permeable layer differs by 14%. From the interlayer heterogeneity to the intralayer heterogeneity model, the heterogeneity between the wells leads to variable flow around the main flow line; the front edge of the water drive is difficult to regulate and promote effectively; the more serious the degree of heterogeneity, the lower the degree of water drive, the greater the pressure drop. After the well network encryption adjustment, the drainage of water discharge pushes the water-driven front edge in parallel, which significantly improves the plane contradiction between the pressure and heterogeneity between the wells. The pressure difference between the vertical and the upper layers gradually disappears, and the inter-layer contradiction is alleviated. The degree of water driving of the two types of heterogeneous models is improved by 30%, but for reservoirs with strong heterogeneity, the existence of large-scale low-permeability zones is still the main enrichment area of remaining oil.

Key words: 9-point well network, row-like encryption, physical structure difference, pressure structure difference, flow field change, residual oil distribution
