The invention relates to the technical field of oilfield exploitation, and discloses a nanometer oil-displacing agent for oilfield oil extraction and a preparation method thereof.The nanometer oil-displacing agent takes modified nanometer silicon dioxide and a surfactant as main components, polymer macromolecules are modified on the surface of the nanometer silicon dioxide to serve as a main body of the nanometer oil-displacing agent, and the nanometer oil-displacing agent is prepared. Under the action of the surfactant, the nano silicon dioxide can flow into the fine throat and the micro throat, and the polymer macromolecules of the branched structure can generate a relatively strong interaction force with the rock, so that the polymer macromolecules are firmly adhered to the surface of the rock, the adhesion of crude oil on the surface of the rock is reduced, a smooth crude oil channel is constructed, and the flowing pressure of liquid is reduced; and crude oil fluidity is improved. The structure of the cross-linking agent contains quaternary ammonium cations, so that the electrostatic repulsion effect between nano silicon dioxide can be greatly enhanced, aggregation between nano silicon dioxide and nano silicon dioxide can be avoided, the interfacial tension can be efficiently maintained, the oil-water interfacial tension is greatly reduced, and the recovery rate of crude oil is effectively increased.

The present application discloses a request processing method, a request processing device and an electronic device. The method includes: in response to a first request queue satisfying a preset condition, adding a target request identifier of a target request to the first request queue, the preset condition being that the number of request identifiers in the first request queue is less than a preset first threshold; after the target request identifier is added to the first request queue, determining the execution time of the target request based on a preset request control strategy, the request control strategy including that the number of requests executed within the same preset time period is less than a preset second threshold; after the target request is executed, removing the target request identifier from the first request queue. Through the scheme of the present application, the traffic pressure of the server during business peak periods can be reduced.

The invention discloses an equipment state reporting method and electronic equipment, and the method comprises the steps: determining whether a user terminal is in an online state or an offline state according to a communication connection state between the user terminal and a server; when the user terminal is in the online state, the Internet of Things equipment is controlled to report the state data to the server according to the first reporting strategy with relatively high reporting frequency, so that a user can check the latest state data of the Internet of Things equipment in real time, and the user experience is improved. When the user terminal is in the off-line state, the Internet of Things device is controlled to report the state data to the server according to the second reporting strategy with the low reporting frequency, due to the fact that the user terminal is in the off-line state, the low reporting frequency is non-inductive to a user, and the user experience is not affected; and the bandwidth, the flow and the storage pressure of the server can be reduced. Therefore, an equipment state reporting scheme giving consideration to the bandwidth, the flow and the storage pressure of the server and the user experience is realized.

This invention discloses a wellhead depressurization gas production device, relating to the field of natural gas extraction technology, which solves the technical problem of existing oil pressure affecting gas well production. The device includes a suction inlet connection assembly, a working cylinder, and a discharge outlet connection assembly connected in sequence. The working cylinder includes a separation joint, a parameter adjustment assembly, and a limiting short-circuit connected in sequence. A venting groove communicating with the parameter adjustment assembly is opened in the middle of the separation joint near its end. A discharge joint is sleeved on the limiting short-circuit. A suction port is opened on the outer wall of the parameter adjustment assembly. A power gas inlet connection assembly is vertically connected to the separation joint, and the power gas inlet connection assembly communicates with the venting groove. The separation joint has a suction through-hole along a direction parallel to the axis, with one end communicating with the suction inlet connection assembly and the other end communicating with the gap between the borehole outer cylinder and the parameter adjustment assembly. This invention can reduce wellhead oil pressure, thereby reducing bottomhole flowing pressure, amplifying pressure differential, and increasing gas well production.

The embodiment of the present invention provides a water distribution device, including: a panel, a water tank and a water distribution pipe; the panel is provided with a plurality of connecting parts, the water distribution pipe is fixed on the panel through the connecting parts, the panel covers the water tank to form a water supply channel, and the water supply channel is connected with the water distribution pipe. In the water distribution device provided by the present invention, the water supply channel is assembled by the panel and the water tank, and is not a square tube in the prior art. Therefore, when making the water supply channel, the panel provided with the connecting part and the water tank can be fully cleaned first, and then the covering panel and the water tank are covered to form the water supply channel, so as to reduce the debris and welding slag inside the water distribution device and avoid the damage of the liquid cooling device caused by it.
