Abstract: The present invention discloses a method for decomposing medium-/low-grade scheelite, specifically comprising steps of: grinding medium-/low-grade scheelite, decomposing in an autoclave by using sodium phosphate and activated magnesium fluoride as leaching agents, and treating by solid-liquid separation to obtain crude sodium tungstate solution and residue. In this way, the medium-/low-grade scheelite is decomposed. Magnesium chloride is added in a sodium fluoride solution to prepare activated magnesium fluoride as a leaching agent. The present invention has the advantage that the high-efficiency decomposition of medium-/low-grade scheelite can be realized with low consumption of leaching agents, and the leaching cost can be greatly reduced in comparison to the existing decomposition processes using sodium hydroxide and sodium carbonate. This process is short in route, simple in operation, readily available and reliable in production equipment, and easy for industrialization.

Abstract: A method for filling an oil and gas well of a fractured oil and gas reservoir with pack-off particles to reduce water and increase oil production comprises the following steps: (1) injecting a filling liquid carrying pack-off particles into a wellbore and a fracture via a wellhead, until a stratum crack/fracture extension pressure is reached or exceeded, or until an injection amount per unit injection pressure is close to zero, or until a preset filling amount of pack-off particles is reached; (2) launching production. The present invention efficiently addresses the problem of water channeling and water production existing in various fractures, by direct filling and recovery filling of the fractures, directly filling of the annular space, and filling from the water injection well to the production well.

Abstract: Methods, systems, and apparatuses are provided that adapt image capture operations to provide refined image capture capabilities. For example, an image capture device captures image data from a sensor operating at a first binning level. The image capture device receives a desired level of zoom, and determines whether the sensor is to be transitioned from the first binning level to a second binning level based on a binning transition threshold. If the sensor is to be transitioned, the image capture device adjusts one or more image capture operations, such as auto focus, automatic exposure, automatic gain, or automatic white balance, based on the desired level of zoom. After an amount of time, the image capture device transitions the sensor from the first binning level to the second binning level. The image capture device then captures image data from the sensor operating at the second binning level.
