大庆探区“十五”勘探规划实践

在概括总结大庆探区“十五”勘探规划方案制定的背景与规划方案特点的基础上,对“十五”实施情况进行深入分析,阐述了“十五”勘探规划方案的指导性、合理性、科学性,总结了“勘探思想的解放铸就了油气发现突破的根本、勘探思路的调整奠定了油气发现突破的基础和‘五个加大’工程的实施确保了油气发现突破的实现”的三个认识。“十五”期间,大庆探区勘探实践效果显著:进一步深化了向斜区岩性油藏下部组合成藏规律的认识,中浅层提交的石油控制地质储量和预测地质储量分别占“十五”期间提交储量的64.3%和74.8%;松辽盆地北部深层天然气勘探获得突破,发现了徐深气田,使该区天然气储量显著增长;实现了海拉尔盆地的工业性开发。

Practice of Exploration Programming during the 10th Five-Year Plan in Daqing Region

On the basis of summing up the setting background of programming during the 10th Five-Year Plan and its features in DaqingOilfield , after the implementation of this program has been analyzed, it is concluded that the program witnesses the guidance, rationalityand science technology, and liberating of the exploration concept is crucial to oil/gas discovery breakthrough, and the adjustment ofexploration concept has been laid the foundation to oil/gas discovery as well as the implementation of "five increase" engineering (i.e.increase investment in integrated research, seismic engineering ,3D acquisition, pre-prospecting drilling and advanced technology) hasensured to realize the breakthrough of oil/gas discovery. During the 10th Five-Year Plan period, notable results has been achieved inDaqing region, including deeply understanding the reservoir-forming law of lower assemblage of lithologic reservoirs in syncline area,the controlled oil geologic reserves and the predicted oil geologic reserves accounted for 64.3% and 74.8% of the total respectively in thesame period; the discovery of Qingshen gasfield is milestone of deep natural gas exploration in northern Songliao Basin, giving theprominent increase of natural gas reserves in this area; realizing the commercial development of Hailaer basin in this period.
