Research on Combined Method of Sedimentary Facies under Multiple Conditional Constraints

Abstract

When we were studying the oil field, this article described the morphology, scale, and connectivity of sand bodies by observing the combination of sedimentary facies in the oil field. At the same time, we also found that the sand body is related to the origin, distribution, physical properties, and Changes in heterogeneity, etc., these factors play a crucial guiding role in the development and adjustment of oil fields. However, in specific phase belt combinations, subjective influence factors are relatively large, and the phase belt maps of oilfields have certain limitations in the development adjustment process. In this paper, the sedimentary facies of the Sapu oil layer in the Harwin Oilfield are re-understood through various constraints such as regional sedimentary environment, well-seismic combined reservoir prediction results, and the matching relationship between fluids and structures on the plane. We make the combination of facies zones more reasonable. Accurate, providing a basis for adjustment of oilfield water injection development.
