Integrated profile controlling and flooding injection system

Abstract

The invention belongs to the technical field of oil field profile controlling and flooding injection systems, and discloses an integrated profile controlling and flooding injection system. The system comprises a solution stirring tank, a feeding room, a control room, a profile control injection pump, a central control cabinet and a living room, wherein the solution stirring tank is divided into a tank a and a tank b by a baffle; a slurry outlet manifold is arranged at the front end of the solution stirring tank; a slurry inlet manifold and a stirrer are mounted at the top of the solution stirring tank; liquid level sensors are arranged at the front and rear ends of the solution stirring tank; the feeding room is divided into a feeding zone and a storage zone; the control room is divided into a cable room, a power distribution room, a control room and a tool room; the central control cabinet is laid in the power distribution room; a liquid level scale is sprayed on the inner wall of the solution stirring tank; a radio frequency admittance material level switch is mounted at the top of the solution stirring tank; a liquid level gauge is mounted at the bottom of the solution stirring tank. The system has the advantages that all control devices are integrated in an explosive-proof and intrinsically safe control cabinet in the power distribution room of the feeding room, all electrical elements belong to intrinsically safe electrical equipment, the control of all units can be realized within one control cabinet, and equipment is very convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of oilfield control and flooding injection systems, and more specifically relates to an integrated control and flooding injection system. Background technique [0002] In oil field control and flooding injection operations, it is necessary to fully and uniformly mix and dissolve various powdery, granular or liquid materials in water, and then use a high-power injection pump to squeeze the solution into the formation. The construction process often requires the injection of a large amount or even thousands of cubic meters of mixed solution, the operation period is long, and the process requirements are relatively strict. The so-called control-displacement injection construction is to use profile control pumps to inject different types of plugging agents, control-displacement agents, and filling agents into the overall oil layer, composite layer or single layer of a well through pumping stations, wells, oil we...
