    In the blink of an eye, Li Yuanzhao, chief engineer of Sinopec Chongqing Fuling Shale Gas Exploration and Development Co.


    Unveiling the mysterious strata

    Unveiling the "veil" of mysterious strata Unveiling the "veil" of mysterious strata

    At the end of 2012, at the beginning of the development of Fuling shale gas field, the domestic shale gas technology and experience were blank, and on-site problems emerged in an endless stream, and difficulties were like mountains in front of them


    "A lot of optimization and improvement, now seems to be subversive, to bear a lot of risk, responsibility, pressure, that kind of suffering, wandering, only those who have experienced it can understand


    During the day, before dawn, he has rushed to the well site, guided the preparation of acid liquid throughout the process, strictly controlled the change of construction parameters, and continuously solved the difficult and complicated diseases on the site; At night, he picked up the lights and fought at night, just to analyze the construction curve more thoroughly and sort out the problems more clearly, often staying up until after


    In the days of day and night, Li Yuanzhao gradually unveiled the mysterious stratigraphic "veil", accumulated rich technical experience, and achieved high production


    Boldly change the inlet material

    Boldly change the inlet material Boldly replace the inlet material

    In recent years, the gas field has implemented three-dimensional development adjustment, improved the recovery rate, and put the new technical proposition of "weaving" the well network more densely, increasing production and reducing costs in front of


    Li Yuanzhao deeply analyzed and studied the shale gas fracturing test process, well materials, organization operation, etc.


    Changing the materials into the well is not a trivial matter, and it takes great courage


    On the day of the first well test, Li Yuanzhao opened the well-in-well mode, pressure, displacement, sand ratio.


    Record test yield

    Record for highest test output Record for test yield

    The development of the Baima block is difficult, and the geological conditions are inherently insufficient, so we can only think of big moves


    Li Yuanzhao took over the burden and led the research team to continuously optimize the process, using a new fracturing process to make the underground cracks more broken and more uniform, and a number of gas wells finally achieved high production


    At each key construction site, Li Yuanzhao kept an eye on the well site throughout the


    In recent years, Li Yuanzhao led the technical research team, innovatively integrated the country's first set of shale gas development five major technical systems, to achieve China's shale gas development technology from scratch, from the follow-up, and ran to the leading major leap, "set in the set" repeated fracturing, all-electric drive fracturing, three-layer three-dimensional development and other technologies to reach the world's leading level, making China one of the few countries to
