中国石油网消息：6月16日，新疆油田吉7井区水平井体积压裂提产试验取得重要进展，该区2口应用“二氧化碳+降黏剂复合体积压裂”技术的试验井，投产51天累计产油突破1200吨，标志着该项技术在中深层低渗高黏稠油油藏实现国内首次工业化应用。

China Oil News: On June 16th, an important progress was made in the volume fracturing production enhancement test for horizontal wells in the Ji7 well area of Xinjiang Oilfield. In this area, two test wells that adopted the "carbon dioxide + viscosity reducer combined volume fracturing" technology have been in production for 51 days, with a cumulative oil production exceeding 1,200 tons. This marks the first industrial application of this technology in deep and medium-low permeability high-viscosity oil reservoirs in China.

吉101井断块南部地面原油平均黏度超8000毫帕·秒，储层渗透性差、原油流动性极低，常规水力压裂、单纯二氧化碳蓄能压裂等传统工艺无法有效动用储量，长期制约区块产能释放。

The average viscosity of the surface crude oil in the southern part of the fault block of Well Ji 101 exceeds 8000 millipascal-seconds. The reservoir has poor permeability and extremely low crude oil fluidity. Traditional techniques such as conventional hydraulic fracturing and simple carbon dioxide energy storage fracturing cannot effectively utilize the reserves, which has long restricted the release of production capacity in this block.

针对这一开发难题，新疆油田勘探开发研究院中深层稠油开发专项团队开展专项攻关，创新研发“二氧化碳+降黏剂复合体积压裂”配套工艺。该技术依托专用复合压裂液体系，把化学降黏剂随压裂液一同输送至储层深部，同步完成储层裂缝改造、原油降黏2项作业，实现储层改造与原油降黏协同增效。

To address this development challenge, the deep reservoir heavy oil development special team of Xinjiang Oilfield Exploration and Development Research Institute carried out a special research effort, innovatively developing the "carbon dioxide + viscosity reducer composite volume fracturing" supporting technology. This technology relies on a dedicated composite fracturing fluid system, transporting the chemical viscosity reducer along with the fracturing fluid to the deep part of the reservoir, simultaneously completing two operations: reservoir fracture modification and crude oil viscosity reduction, achieving synergistic enhancement of reservoir modification and crude oil viscosity reduction.

新工艺大幅提升了原油动用黏度上限，同时具有地层补能、产能提升、储层改造等多重作用。从生产数据来看，2口试验井生产工况稳定，单井最高日产油量超出前期试验设计指标，增产效果显著。

The new process has significantly increased the upper limit of crude oil mobility viscosity, and also has multiple functions such as reservoir replenishment, production capacity enhancement, and reservoir modification. From the production data, the production conditions of the two test wells are stable, and the maximum daily oil production of each well exceeds the design indicators of the previous tests, with a remarkable increase in production.

此项技术填补了新疆油田中深层低渗高黏稠油油藏高效开发的空白，为油田同类型未动用稠油储量盘活，提供了可复制、可规模化推广的技术手段。

This technology has filled the gap in the efficient development of deep-layer low-permeability and high-viscosity oil reservoirs in Xinjiang Oilfield, providing a replicable and scalable technical means for revitalizing the unexploited heavy oil reserves of the same type in the oilfield.
