Abstract: The present disclosure provides a device for separating sub-micron particles in the air, comprising a first separation channel, a second separation channel and a collection device which are connected in sequence, wherein each of the first separation channel and the second separation channel is of a rectangle structure with two open ends, the height H1 of the first separation channel is greater than the height H2 of the second separation channel, and each separation channel is provided with a vibration sound source and an antimicrobial coating layer. Based on the agglomeration theory of suspended particles in the air by ultrasonic standing waves, the device can aggregate sub-micron suspended particles flowing into each channel of the device on the upper and lower wall surfaces and the centerline of the channel, and sterilize the aggregated particles, thereby effectively removing the sub-micron suspended particles in the air.

Abstract: A methodology using an interwell connectivity model for hydrocarbon management is disclosed. The interwell connectivity model may include interwell connectivity metrics indicative of fluid interconnectivity amongst pairs of wells and may be used as predictive or prescriptive for enhanced oil recovery (EOR). As predictive, the interwell connectivity model may be used to determine an effect of gas injection into the reservoir on one or more aspects of EOR, such as reservoir pressure or production rates. As prescriptive, the interwell connectivity model may be used to improve or optimize various stages of EOR, such as during drilling or construction of the extraction site, during primary depletion, or during one or more huff-and-puff cycles.

Abstract: A methodology for modeling oil/water or gas/water paleo zone reservoir properties for hydrocarbon management is provided. Reservoir simulations in a subsurface, such as in an oil region bounded by a gas cap and a water region, may use an initial reservoir simulation model. The methodology determines one or both of the oil/water or gas/water interfaces to honor the equilibrium state of the subsurface. The current configuration of the subsurface may be the result of one or more processes, such as a drainage process and an imbibition process, each of which have different associated curves reflecting the physical phenomena of the fluid/rock properties in the subsurface. The methodology honors the physical process, including comporting with the different curves and with the available data, in order to determine the current state of the subsurface, including one or both of the oil/water or gas/water interfaces.

Abstract: A method and system are described for creating subsurface models that involve the use of isomorphic reversible scanning curve for simulating hysteresis in reservoir simulators. The method includes constructing a subsurface model for a subsurface region and using the subsurface model in simulations and in hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development, and/or hydrocarbon production.

Abstract: An electrical connector assembly including an electrical connecting member, at least one connector, and at least one metal cover is provided.

The metal cover is disposed on the electrical connecting member, such that the electrical connecting member is located between the metal cover and the connector, and the connector is covered by the electrical connecting member.

Abstract: A digital printing device, comprising a suction transport means (1). The suction transport means (1) comprises a transport belt (11) used for transporting a sheet material. At least one first suction box (14), which is used for sucking the sheet material on the transport belt (11) by means of negative pressure during transport, is provided in the space defined by the transport belt (11). Multiple first suction holes in communication with the first suction box (14) are provided on the transport belt (11). At least one side of the first suction box (14) is provided with a movable door (15) which moves in a direction perpendicular to the transport direction to make the first suction box (14) fit the sheet material to maintain a negative pressure state. Using the transport belt (11) during printing, the digital printing device avoids the problem of poor registration accuracy, and improves the printing effect.
