2results about How to "Improve sweeping efficiency" patented technology

This utility model discloses an associated gas power generation tail gas reinjection system, including a gas-liquid mixer connected to a tail gas outlet pipe and a liquid-liquid mixer. The liquid-liquid mixer is connected to the bottom of an oil well produced water storage tank and an additive storage tank via pipelines. A compressor and a gas-liquid distribution mechanism are sequentially connected to the outlet of the gas-liquid mixer. The gas-liquid distribution mechanism includes a main distribution pipe connected to the compressor outlet, with multiple branch distribution pipes connected to it. The outlets of the branch distribution pipes are connected to the injection well. This utility model provides an associated gas power generation tail gas reinjection system that can utilize associated gas power generation tail gas to increase production, reduce the gas injection cost for oilfield production enhancement, and achieve synergistic reinjection of power generation tail gas and oil well produced water, thereby improving sweep efficiency.

The application relates to the technical field of automatic navigation, and provides an automatic navigation control method and system of an unmanned sweeper. The method comprises the following steps: obtaining a historical monitoring video of a to-be-cleaned area, generating an initial cleaning path of the to-be-cleaned area based on the historical monitoring video, and predicting a cleaning time period corresponding to the initial cleaning path; obtaining multi-source data information of a target area, and constructing a dynamic environment semantic map sequence corresponding to the to-be-cleaned area in the cleaning time period based on the multi-source data information; wherein the to-be-cleaned area is contained in the target area; performing optimization processing on the initial cleaning path based on the dynamic environment semantic map sequence to obtain a target cleaning path; and controlling the sweeper to perform a cleaning task based on the target cleaning path. The method helps to improve the adaptability of the sweeper in a complex environment.
