Overview

The blending skid is specially developed to mix the fracturing fuid, proppant and various additves according to the preset proporton, and to convey the mixed fuids under certain pressure to the fracturing pump skid. The blending skid consists of the following components and systems: skid frame, engine, transmission case, mixing/agitatng system, screw type sand conveyer, hydraulic system, suction and discharge manifolds, electric circuit and control system.

Features

1. It is mainly developed for ofshore sand control fracturing service. It is used to accurately mix and convey the sand-laden fuid.

2. The blending skid is of split-structure and the individual weight is controlled within 9 tons, which is convenient for hoistng.

3. The design ensures the quick switch and interchange of the suction and discharge pipe systems, which helps realize the double suctions and double discharges and brings the convenience of the equipment arrangement. It is achieved by controlling the isolating valve. 

4. The blending skid is controlled by the hydraulic driven electric control system. It has two control modes, the auto control mode and the manual control mode, which can be quick switched when it is required. 

5. The sand auger may be either place in the middle or at the rear of the skid for the easy and contnuous feeding sand.

6. The blending skid may be collocated with diferent kinds of additves systems which have various sizes or brands of additves.

7. The blending skid introduces SJS ABCS blender auto control system, which ensures the achievement of auto control over the sand fluid concentration, the sand auger rotating speed, the feeding speed of the additives and the level of the sand fluid.
