摘要
通过对延长探区勘探历程、数据以及重要历史事件进行梳理和分析,以油气产量变化和地质理论发展为主线,将延长探区勘探历程划分为4个阶段:初始勘探阶段(1905—1949年)、持续探索阶段(1950—1981年)、快速发展阶段(1982—2006年)和稳油增气阶段(2007年至今)。详细总结了近10年延长石油在特低—超低渗油藏勘探、盆地东南部致密天然气勘探和非常规陆相页岩气勘探等方面取得的理论认识,及其对油气快速增储上产的重要作用,期望对以后的油气勘探工作起到启发和参考作用。
During the 100⁃year history of oil and gas exploration in Yanchang exploration area of Ordos basin,a number of major progress and breakthroughs have been made,all of which are of great significance.After analyzing the exploration history,data and important histori⁃cal events,and based on the variations of oil and gas production and the development of geological theory in Yanchang exploration area,the exploration process is divided into four stages:Early exploration stage(1905-1949),sustained exploration stage(1950-1981),rapid devel⁃opment stage(1982-2006)and stabilizing oil production meanwhile increasing gas production stage(2007-).Additionally,this paper sum⁃marizes the theories and understandings in exploring ultra⁃low-extra⁃low permeability reservoirs,tight gas and continental shale gas in the southeastern area of the Ordos basin in recent ten years,and analyzes their important roles in the rapid increase of oil and gas reserves and production.Our findings may provide implications and references for future oil and gas exploration.
