reservoir delineation meaning in English

储集层划分

With the development of oil fields , many old reservoirs in the east of china enter the high water - bearing development period . sustaining a high and stable production rate faces severe challenge . the key to preserve oil output in high water cut period is dependent upon the understanding degree to the properties of residual oil distribution . from 1980 ' s , while the study of the reservoir flow unit was proceeded alongside , it has been more widely utilized to characterize reservoir feature and remnant oil distribution . study of reservoir flow unit plays . both theoretically and practically . an important role in recognizing reservoir heterogeneity . performing a high - definition reservoir delineation and understanding the distribution of the remnant oil in the reservoir
随着油田的不断开发，我国东部许多老油田已进入高含水期开采阶段，保持油气产量的稳定面临严竣的挑战，而高含水油田稳产的关键取决于对剩余油分布的认识程度。八十年代以来，随着对储层流动单元研究的不断深入，它越来越广泛地被应到油藏描述和剩余油研究中来，流动单元研究对于认识储层的非均质性、提高油藏描述精度、搞清剩余油分布具有重要的理论意义和实际意义。
