摘要
Abstract
Northern Songliao Basin has entered a stage of high-degree exploration and development,with increasing difficulties in discovery and production of conventional oil and gas.All previous oil and gas resources evaluation pro-cesses are summarized to illustrate the variation of petroleum resources potential in middle-shallow strata of north-ern Songliao Basin due to the progress of petroleum exploration theory and resources evaluation technology.Charac-teristics of middle-shallow petroleum systems and their control on oil and gas distribution are re-summarized guided by the concept of super basin and combined with the new theoretical understanding of shale oil accumulation in shale strata series,and remaining resources potential and distribution laws of conventional and tight oil in northern Songliao Basin are discussed based on the results of the fourth oil and gas resources evaluation,proposing specific research suggestions for further strengthening exploration and development.The results show 3 sets of composite pe-troleum systems developed in upper,middle and lower parts of middle-shallow strata in northern Songliao Basin,in-cluding 10 simple petroleum systems,which constitute the whole petroleum system of middle-shallow strata.Pre-dicted undiscovered resources of conventional oil and tight oil exceed 30×108 t.Among them,remaining resources of conventional oil are mainly distributed in Saertu and Putaohua reservoirs in middle composite petroleum system.Putaohua reservoir above source rocks in Gulong sag and Sanzhao sag,multi-layers in proximal slope of Longhupao terrace and Saertu reservoir in western distal slope have hundreds-millions tons of resources potential for efficient re-serves increase and rapid production increase.Remaining resources of tight oil are mainly distributed in Gaotaizi reservoir in middle composite petroleum system and Fuyang reservoir in lower composite petroleum system.Fuyu reservoir in central-southern Daqing Placanticline and in Songfangtun-Zhaozhou low uplift of Sanzhao sag,as well as Gaotaizi reservoir in Qijia-Gulong sag are expected to form new prospects of exploration and development with two hundreds-millions-tons scale and two 50 millions-tons scale.Fine exploration and precise development are effec-tive ways to rejuvenate mature areas.The progress of exploration and development theory and technology promotes sustainable high and stable production of mature oilfield.关键词
