Lacustrine Deposits Of Oil Reservoir Connected Algorithm For Subdivision

With the further development of oil fields, the need for more in-depth understanding of the reservoir, oil reservoir contrast is revealed morphological features of the basic means of understanding on the oil reservoir contrast depends on the accuracy, but the breakdown of data involved in oil contrast than the larger, relatively high precision, hand-contrast difficult to achieve, profile visualization research is to correctly understand the complexity of geological structure and tectonics is an important means.This paper presents a segmentation algorithm for reservoir connectivity, the system is mainly based on basic information about a single well, single well test interpretation results of the data, a small layer in the single well data, a small layer of connectivity within the various types of detailed analysis of sandstone, and then analysis, the intuitive and flexible image display.Through the reservoir to number processing, then sort the reservoir, and then sort the completion of the reservoir to equalize treatment of data obtained Stretch reservoir; On this basis, data on oil Stretch match, match to complete the data for display into the reservoir pool match . Match the success of penetration in accordance with the nature of the connectivity of reservoir (sedimentary facies) data analysis, carried out in accordance with the connectivity of the reservoir permeability sandstone connectivity into a class, second class connectivity and three sandstone sandstone connectivity, and use different colors to display.The proposed method of profile generation for irregular layers of data, contrast stretching algorithm using a balanced realization of a single thin layer of a detailed subdivision, quickly and efficiently achieve the construction of reservoir connectivity; on the basis of layers connected tracking to solve the problem of reservoir subdivision connectivity, and a small layer of matching algorithm which has been optimized to improve the visualization of segments connected generation efficiency.
