已探明未开发区块分类优选方法研究

Researches of Classification and Optimization Methods of Proved Undeveloped Blocks

随着大庆油田勘探开发工作的不断深入，剩余未开发区块的丰度越来越低，储层物性越来越差，地质条件越来越复杂，开发难度越来越大。为进一步落实大庆油区已探明未开发区块的状况，积极探索其经济有效的开发办法，挖掘未开发区块的可开发潜力，对已开发区块的动态特点进行深入理论分析的基础上，以油田为单位，合理划分油藏的评价单元，提出一套适合外围油田油藏地质特征的未开发区块评价优选方法，为我国类似低渗透油田未开发区块的合理有效开发提供借鉴。

With the development of Daqing oilfield, abundance of undeveloped blocks is more and more lower; physical properties of reservoirs are worse and worse; geologic conditions are more and complicated; exploitation become more and more difficult. In order to make sure the conditions of proved-but-undeveloped blocks in Daqing oil-field, to search economically effective development methods, and to tap development potentials of the undeveloped zones, a set of evaluation and optimization methods of undeveloped blocks suitable to the geologic features of peripheral reservoirs of Daqing is put forward on the basis of analyzing theoretically the dynamic characters of developed zones. These methods take oilfield as a unit, and the evaluating unit of reservoirs is divided reasonably. They could be used for reference to develop rationally and effectively the undeveloped blocks of low-permeability oilfields similar to Daqing.
