Problems solved by technology

However, when the sewage produced by the production well contains sulfide ions, it will have a great impact on the oil displacement performance of the ultra-high molecular polymer solution, thereby affecting the oil displacement efficiency; and when the sewage contains sulfide ions, with the How does the increase of mass concentration affect oil displacement efficiency? Currently, there are few visualization studies on this aspect

Abstract

The invention discloses a device and a method for measuring reinjection oil displacement of sulfur-containing sewage by using an ultra-high molecular polymer. A first ultra-high molecular polymer storage tank is sequentially connected with a first ball valve, a first pressure pump, a first ultrasonic flowmeter and a first PC pipe, and a second ultra-high molecular polymer storage tank is sequentially connected with a sixth ball valve, a second pressure pump, a second ultrasonic flowmeter and a second PC pipe; a first rock core and a second rock core are arranged in a PC box body, and a water storage tank and a fifth ball valve are connected in series, then connected with a fourth ball valve in parallel and then connected with a steam generator, a small screw pump and a hot steam inlet together. The method comprises the steps: 1, a preheating stage; 2, an oil displacement stage; 3, displacement adjustment and pressure value record; 4, oil displacement efficiency calculation; and 5, thechange of the concentration of the storage tank and the repeat of the above steps. The method is good in simulation effect, and the result provides guiding significance for the reinjection oil displacement of the sulfur-containing sewage by adopting the high-molecular polymer under actual working conditions on site.

Description

technical field [0001] The invention relates to a device and method for measuring oil displacement effect, in particular to a device and method for measuring oil displacement by reinjection of sulfur-containing sewage by ultrahigh molecular polymer. Background technique [0002] As the oil field continues to produce, the output of recovered oil also decreases, so some technologies need to be used to enhance the recovery factor. In many old oil fields, ultra-high molecular polymers are commonly used for oil displacement to enhance oil recovery. When using ultra-high molecular polymers to flood oil, factors such as protecting water resources and protecting the environment must also be considered. Therefore, oil fields often use sewage produced from production wells instead of water sources required by water injection wells to drain water together with ultra-high molecular polymers. Injection well reinjection. The use of reinjected sewage to configure ultra-high molecular pol...
