Abstract: The present invention provides a method for in-depth profile control and displacement of low-permeability oil reservoirs, comprising: sequentially injecting a flexible and elastic particle-containing pre-slug, a polymer microsphere-containing main slug and a flexible and elastic particle-containing protective slug into an oil layer, and the three slugs have a volume ratio of total injection amount of 1-2:6-8:1-2. The invention provides a method for in-depth profile control and displacement by using styrene-based flexible and elastic particles in combination with the polyacrylamide polymer microsphere, wherein the flexible elastic particles can block cracks and large pore channels of the oil layer, and the polymer microsphere can displace the remaining oil in the oil layer. In the present invention, different slugs of profile control and displacement system are combined to achieve the objective of blocking cracks and large pore channels, displacing crude oil, and improving oil well recovery.

Abstract: One or more embodiments of the present disclosure provide an augmented reality presentation including a digital model of a product in connection with a camera stream. For example, systems and methods described herein provide a call-to-action associated with a digital model of a corresponding product. In response to detecting a selection of the call-to-action, systems and methods described herein provide the digital model. The system and methods described herein also activate a camera interface of a networking system application and render the digital model of the product within the camera interface. In this way, the systems and methods provide a portable user experience of trying on or otherwise sampling a product via an augmented reality presentation on a client device.
