Abstract
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.关键词
