Problems solved by technology

[0002] High-efficiency polymer flooding preparation technology is the key to implementing polymer flooding in offshore oilfields. However, the offshore platform has a small space, limited load-bearing capacity, and large single-well injection volume. It is difficult to copy the polymer preparation equipment in onshore oilfields. It is difficult to popularize and apply process technology and equipment in large areas of offshore oilfields

Abstract

The invention discloses a polymer preparation system of an offshore platform without a curing tank. The system comprises a dispersing and mixing system, a first conveying pump, a polymer forced stretching device, a buffer stirring tank, a second conveying pump, a mother liquid diluting system and a target liquid storage tank which are connected in sequence; the dispersing and mixing system comprises a trough, a spiral feeder, an air blower, an ejector, a water feeding pump I and a mixing, dissolving and stirring tank; a discharging port of the material groove is connected with a feeding port of the spiral feeder, a discharging port of the spiral feeder is connected with a first inlet of the ejector, the output end of the air blower is connected with a second inlet of the ejector, and an outlet of the ejector and the output end of the first water feeding pump are connected with a mixing, dissolving and stirring tank; the mother liquor diluting system comprises a mother liquor diluting tank and a second water feeding pump which are connected with each other. On the premise that the number of the curing tanks is not increased, the preparation concentration is improved, the dissolution time is shortened, and technical support is provided for polymer preparation of the offshore platform.

Description

technical field [0001] The invention relates to the technical field of offshore oilfield development, in particular to a polymer preparation system on an offshore platform without a maturing tank. Background technique [0002] High-efficiency polymer flooding preparation technology is the key to implementing polymer flooding in offshore oilfields. However, offshore platforms have small space, limited load-bearing capacity, and large single-well injection volume. It is difficult to copy the polymer preparation equipment in onshore oilfields. Process technology and equipment are difficult to be popularized and applied in large-scale offshore oil fields. The main body of the polymer process from dry powder to solution can be divided into three parts, which are polymer dry powder transportation, dry powder dissolution and maturation. Onshore oilfields can achieve complete dissolution of polymers by increasing the number and volume of maturation tanks, while offshore Limited by ...
