对21世纪大庆油田开发前沿技术发展的初步思考

Preliminary thinking on leading edge technology development of Daqing oil field in the 21st century.

21世纪大庆油田开发面临的新挑战具体反映为 :①已累计采出石油可采储量的 70 .3 2 % ,储采失衡日趋严重 ;②开发难度急剧增大 ,总体经济效益逐步变差 ;③重组改制要求更高 ,市场竞争更加激烈。今后大庆油田开发工作从以原油产量为中心转移到以经济效益为中心 ,从以持续稳产为总目标转移到以可持续发展为总目标 ,要大力加快两个层次的前沿性科技发展。第一层次为近期前沿技术 ,以提高探明储量动用程度和采出程度为重点 ,包括 3套核心技术 :①高含水后期提高水驱采收率配套技术 ;②聚合物驱综合调整和三元复合驱配套技术 ;③大庆外围“三低”(低渗透率储集层、低储量丰度和低单井产能 )油藏有效开发配套技术。第二层次主要着眼于 2 1世纪油田长远发展需要 ,重点在 3个方向积极进行新的探索和研究 :①三次采油后的泡沫驱、微生物驱和其它接替新技术 ;②有效开发深部致密层天然气藏、复杂断块致密油气藏新增探明储量的相关技术 ;③国内外油田开发市场需要的相关技术。今后要以改善大庆油田开发总体经济效益为中心 ,大力发展、应用高水平油气开发技术 ,不断深化重组改制和现代企业管理 ,努力在 2 1世纪实现油田可持续发展。图 2参 2 (王孝陵摘 )

In the 21st century, Daqing oil field has to face new challenges mainly reflected in: (1)Unbalance in reserve production ratio is tending to be serious after recovering cumulative productidon 70.32 % of petroleum recoverable reserve; (2) Development difficulty increasing dramatically, with overall economic benefit getting poor;and (3) More strict requiements must be put forward in recognization and restructuring, due to the fact that market competition becomes more intense. From now on, the key work during development of Daqing oil field will be coverted from petroleum production rates to economic benefit, and overall targets will be coverted from continuous stable production to sustainable development, leading edge technology development in two levels will be accelerated. One level is about recent leading edge technology, focusing on increasing the employment percentage of and the total oil produced over the proved OOIP, which includes 3 sets of core techniques: (1)A complete set of techniques for improving waterflooding recovery factor at late high water cut stage; (2)Polymer flooding combined with ASP technique;and (3) Completion set of techniques for effective development of peripherial low permeability, low reserve richness and low single well productivity reservoirs. Another level is mainly about oil field long term development requirements in the 21st century, focusing on new exploration and investigation in three directions: (1)Foam flooding, microbial flooding and other replacing new techniques after EOR; (2)Related techniques for effective development of newly incremental proved reserves in deep tight natural gas reservoir and complex fault block oil and gas reservoirs;and (3)Related techniques required by market development for oil fields both at home and abroad. In the future, focus will be put on improving overall economic benefit of developing Daqing oil field through energetically developing and applying advanced hydrocarbon recovery techniques, continually deepening reorgnization, restructuring and mordern enterprise management and endeavoring to realize oil field sustainable development in the 21st century.andendeavoringtorealizeo
