Description

Single well polymer dispersion dissolving mixed injection skid-mounted device TECHNICAL FIELD

[0001] The present application belongs to the technical field of polymer injection skid-mounted device, and particularly relates to a single well polymer dispersion dissolving mixed injection skid-mounted device. BACKGROUND

[0002] The single well polymer dispersion dissolving mixed injection skid-mounted device is mainly applied to online mixing of polymer solution drag reducer in oil and gas field fracturing engineering, and can quickly configure high-quality polymer solution without fisheye and lump, and efficiently provide matching services for the fracturing engineering.

[0003] When the polymer solution is configured, first, the polymer dry powder is dispersed and mixed in a certain amount of water through polymer dispersion dissolving, and the polymer dry powder particles are fully wetted; then the polymer dry powder particles are converted from a dispersion system into a solution in water through polymer ripening. The polymer ripening process needs to go through two stages. First, water molecules penetrate into the polymer molecules, causing the polymer volume to expand, which is called "swelling", and forming polymer micelles; then the polymer molecules uniformly diffuse into the water molecules, forming a completely dissolved molecular dispersion system, i.e. ripening liquid. In the polymer solution ripening link, the ripening tank stirring ripening process is currently mainly used.

[0004] When the single well polymer dispersion dissolving mixed injection skid-mounted device is used, the polymer is ripened through the ripening system. However, the ripening system only simply performs dispersion dissolving mixing when in use, so that the polymer solution entering the ripening tank is not fully dissolved, and "fisheye" (undissolved polymer lump) and air bubbles are prone to be generated. This causes the polymer solution to have a long ripening time in the ripening tank, and the working efficiency is low, which causes more ripening tanks to be needed for ripening the polymer solution, and the ground equipment investment is large and the land occupation area is large.
