中国石油网消息：4月21日记者获悉，集团公司纳米化学重点实验室大港油田分实验室成立，标志着在攻关大港复杂断块砂岩油藏纳米化学驱油技术、赋能老油田高效开发上迈出了坚实的一步。

China Oil News: On April 21st, it was learned that the Nanotechnology Chemistry Key Laboratory of the Group Company's Dahan Oilfield Branch Laboratory was established. This marks a solid step forward in the research on the nano-chemical oil displacement technology for complex fault-block sandstone oil reservoirs in Dahan and in enhancing the efficient development of old oilfields.

纳米智能驱油技术是当今石油领域的前沿技术，纳米驱油剂具有“尺寸足够小、强憎水强亲油、分散油聚并”的特点，可实现智能找油、智能驱油、智能避水和残存油全驱替。

Nanomaterial-based intelligent oil displacement technology is a cutting-edge technology in the petroleum field today. Nanomaterial-based oil displacement agents possess the characteristics of "being sufficiently small in size, having strong hydrophobicity and strong hydrophilicity, and being capable of dispersing and aggregating oil", enabling intelligent oil detection, intelligent oil displacement, intelligent water avoidance, and complete displacement of residual oil.

大港油田面对自然递减率高、增储上产难度大等现实难题，积极联合中国石油勘探开发研究院，依托集团公司统筹部署，瞄准复杂断块砂岩油藏纳米技术应用等领域，共建大港分实验室。

The Dagang Oilfield, confronted with the challenges such as high natural decline rate and great difficulty in reservoir expansion and production, actively collaborated with the China Petroleum Exploration and Development Research Institute. Relying on the overall deployment of the group company, they focused on areas like the application of nanotechnology in complex faulted sandstone reservoirs, and jointly established a Dagang sub-laboratory.

大港油田分实验室将推进“纳米+”理论技术攻关，打造技术示范区，构建纳米驱开发技术体系。同时，稳步推进技术落地，加快试验纳米辅助压驱、“纳米+气驱”协同技术攻关，开展整装油藏纳米水驱先导试验，以科技赋能老油田高效开发、长期稳产。

The laboratory of Dagang Oilfield will carry out research on the "nano+" theory technology, establish a technical demonstration zone, and build a nano-driven development technology system. At the same time, it will steadily promote the implementation of the technology, accelerate the research on nano-assisted pressure drive and "nano+ gas drive" collaborative technology, and conduct pilot tests of nano water drive in large-scale oil reservoirs. By leveraging technology, it aims to enhance the efficient development and long-term stable production of old oilfields.
