First, the use of products
Oil cleaning agent is composed of organic solvent, the surface active agent, and a variety of organic compound, with washing, dissolving and dispersing synergistic effect of wax, resin and asphaltene, and other grease has good cleaning effect, wide range of uses. With wax and wax double performance can be used to remove oil and crude oil gathering and transportation pipeline, such as wax, resin and asphaltene deposition, with wax dissolving speed, the saturated solution characteristics of higher wax content, and can prevent the wax, can significantly prolong the period of Xi Jingzhou.
1 cleaning shaft: in the process of production of high condensate, the shaft of the wax is serious, frequent operation, affecting the normal production of oil wells, with the additive, good cleaning effect, convenient construction. Has a unique cleaning effect for the formation of tubing wall stubborn grease.
2. The reservoir cleaning blocking: the acidification is used to prevent expansion construction of pre cleaning, full contact with the acid and formation, improve the acidizing anti swelling effect, for plastic sand screen of pre cleaning, can also be used for oil well formation wax and oil plug, etc. the cleaning solution plugging.

Three, the use of methods
1 when used in shaft cleaning, the product can be mixed with oil according to the ratio of 0.5-5%.
2 oil paraffin plugging, the formation of cleaning agent from the pipe into the stratum can be.
3 oil pipeline cleaning, using cement truck pump into the formation of cleaning agent, soak the reaction 2-8 hours, the pressure can be.

Four, storage and transportation
1 store in a cool, ventilated warehouse. Away from the fire, heat, direct sunlight. Keep container seal. Should be stored separately with the oxidant, avoid mixing.
2 transport and handling should be handled gently and prevent violent collision, extrusion, inversion, so as to avoid damage to packaging and containers, leakage.

Five, matters needing attention
1 smoking is strictly prohibited in the workplace. Mechanical equipment and tools for the prohibition of the use of easy to produce sparks.
2 in the course of use, the staff should wear self absorption filter gas mask (half mask), wear chemical safety glasses, wear gas, anti-static clothing, wear rubber oil resistant gloves. Ventilation systems and equipment using explosion proof type. To prevent steam from leaking into the air in the workplace. Avoid contact with oxidizing agents. When filling, the flow rate should be controlled, and the grounding device, to prevent the accumulation of static electricity. When moving to light light unloading, equipped with the appropriate variety and quantity of fire equipment and emergency handling equipment. Empty containers may contain harmful substances.
3 once the leakage occurs, eliminate all ignition sources. According to the liquid flow and vapor diffusion influence area delimit warning zone, regardless of the personnel from the wind, the wind to evacuate to safe areas. No contact or cross leakage. As far as possible to cut off the source of leakage. To prevent leakage of water into the water, sewer, basement or restricted space. Small amount of leakage: absorption of sand or other non combustible material. Is a clean, non - spark tool for collecting and absorbing material. A large leak: construct a barrierpit to contain. A lot of liquid with sand or vermiculite, inert material absorption. With foam cover, reduce evaporation. Explosion proof pump transferred to tankexclusive collector.
