doi:10.3969/j.issn.1672-7703.2018.06.003

摘要/Abstract

摘要： 大港油田历经50多年勘探，效益增储面临着井位确定难、储量新增难、储量升级难、储量动用难、效益提升难等诸多挑战。但大港油田资源优质、资料丰富、配套完善，效益增储潜力大。积极应对挑战，深入挖掘潜力，利用新资料、建立新模式，油田外围新区块寻找高效储量；突破老观念，预探新层系，油田上下新层系实现效益增储；油藏再认识、工艺再创新，油田内部新目标发现高效储量，探索形成老油田效益增储的新方法，使老油田增储再续青春，老油田增效闯出新路。实践证明，该方法是老油田效益增储的“金钥匙”，是老油田提质增效、走出困境的有效途径，对老油田实现持续稳健发展具有一定借鉴意义。

Abstract: After more than 50 years of exploration, the Dagang Oilfield faces many challenges such as difficulty in locating wells, difficulty in increasing reserves, difficulty in upgrading reserves, difficulty in producing reserves, and difficulty in enhancing efficient production. With high-quality resources, abundant data, sophisticated equipment and facilities, and great potentials for reserve increase in the Danggang oilfield, valid reserves have been discovered in the surrounding zones by actively dealing with challenges, enlarging potentials and establishing new development models based on new data; efficient reserve increase has been realized by breaking through old ideas and pre-exploring new layers; and new reserve targets have been found by re-recognizing old reservoirs and innovating processes, which make the oilfield active again and provide new ways to increase reserves. It has been proved that these practices are "gold keys" to increasing reserves, and good ways to break through difficulties and keep sustainable and healthy development of mature oilfields.

Key words: economical reserve increase, new block, new layer, new target
