Modified nano graphite and polymer composite material thereof, preparation method and use in high temperature and high salinity oil reservoir

The present disclosure relates to the field of oilfield chemistry, in particular to a composition for multi-component composite intercalation, a method of preparing a graphite system and a method of profile control and water shutoff.

Composition for multi-component composite intercalation, method of preparing a low-temperature expandable graphite system and method of profile control and water shutoff in deep oil reservoir

Provided a skid-mounted dispersed particle gel production device, dispersed particle gel and a preparation method and use thereof. The device sequentially comprises, in a delivery direction of a material flow, a jet blending system, a bulk gel chemical crosslinking reaction system, a shearing and grinding system, a storage system. and an intelligent regulation system Rapid crosslinking reaction of bulk gel in a medium/high-temperature oil reservoir and large-scale preparation of multiscale dispersed particle gel can be realised, and the device is applied to continuous production in a complex environment such as a tidal flat, a hill and an offshore work platform.

Skid-mounted dispersed particle gel production device, dispersed particle gel and preparation method and use thereof

An oil-soluble coated particle flow modifier, a preparation method thereof, and a use thereof in fractured-vuggy carbonate reservoirs mining. The oil-soluble coated particle flow modifier is of a core-shell structure, which has a core layer of a coated core and a shell layer of a coating agent, wherein the coated core is made of a plugging material, and the coating agent consists of petroleum resin and hollow beads. Based on the total weight of the coated particle flow modifier, the content of the petroleum resin, the hollow beads, the cotton linters, and the coated cores is 10-40 wt %, 9-40 wt %, 1-10 wt %, and 35-80 wt %, respectively. A preparation method of the coated particle flow modifier and a use of the coated particle flow modifier in fractured-vuggy carbonate reservoirs mining to improve oil recovery is also provided.
