Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, specifically to a chemical additive semi-trailer for oilfield fracturing operations. Background Technology

[0002] A semi-trailer is a trailer without front wheels that relies on a tractor unit for support and power, with part of its weight borne by the tractor unit (via a saddle / fifth wheel connection). Unlike a full trailer, a semi-trailer cannot travel independently and must be used in conjunction with a tractor unit. A chemical additive semi-trailer is a semi-trailer specifically designed for convenient application of chemical agents.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most existing semi-trailers are not specifically designed for oilfield fracturing operations, and cannot store large quantities of chemicals or quickly add them to save time required for fracturing operations. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical additive semi-trailer for oilfield fracturing operations, including a chassis system, a power system located above the front of the chassis system, and a cabin system located at the rear of the chassis system;

[0007] The chassis system has hose reels on both sides of the main beam, the cabin system has multiple compartments, and a chemical agent addition system is located at the rear of the cabin system. The horizontal center lines of the power system, cabin system and chemical agent addition system are aligned.

[0008] The chemical reagent addition system includes a chemical reagent storage tank, with a stirrer installed through the top of the chemical reagent storage tank, an electro-sensor level gauge installed on one side of the top of the chemical reagent storage tank, a level viewing window installed on the side of the chemical reagent storage tank, an inlet and an outlet of the chemical reagent storage tank, a discharge valve installed at the bottom of the chemical reagent storage tank, a chemical reagent discharge pump installed on one side of the discharge valve, and a flow meter installed on the outlet pipeline of the chemical reagent discharge pump.

[0009] The beneficial effects of this utility model are: the necessary power, multiple compartments and chemical agent storage tanks are installed on the upper part of the chassis, and the multiple storage tanks have independent liquid inlets and liquid outlets. By controlling the opening and closing of different valves, chemical agents can be filled into different storage tanks and output from the corresponding storage tanks.

[0010] To achieve the storage and transportation of a certain amount of chemical reagents:

[0011] The configuration is further defined as follows: the number of chemical storage tanks is several, and the multiple chemical storage tanks are distributed in a matrix within the cabin system.

[0012] By adopting the above technical solution, a large amount of chemical agents can be stored, and the hoses connected to the hose reel can be used to carry out chemical agent discharge operations.

[0013] To enable on-site fluid sampling and testing, as well as manual control and intervention during fracturing operations:

[0014] The configuration is further defined as follows: the cabin system includes a control room, and an experimental room is provided on one side of the control room. A liquid filling room is provided on the rear side of the experimental room. The control room and the experimental room are equipped with auxiliary systems such as air conditioning, heating devices and lighting.

[0015] By adopting the above technical solution, multiple chambers are provided to meet different needs for experimentation, control, and reagent addition.

[0016] To reduce the workload of on-site pipeline connections:

[0017] The further configuration includes: a rotary joint is provided at the reel suction port of the hose reel, and the hose reel is self-retracting.

[0018] By adopting the above technical solution and using a self-retracting hose reel, the efficiency of hose connection and retrieval can be improved.

[0019] To meet the power requirements of the semi-trailer's cabin system and chemical dosing system:

[0020] The power system is further configured to include a diesel generator and is electrically connected to the hull system and the chemical agent addition system, which may also be driven by an engine or an electric motor.

[0021] By adopting the above technical solutions, power can be supplied in multiple ways.
