First, the use of products
In order to protect the oil and gas reservoir and prevent the invasion of the external liquid, the temporary plugging agent is commonly used. KD-44 temporary plugging agent is a high efficiency oil soluble shielding temporary plugging agent, which is composed of a variety of organic and inorganic compounds as raw materials, and then supplemented with highly active surfactant. This product is a light yellow or yellow liquid suspension, in aqueous medium in suspension dispersed state, can be dissolved in oil. It is mainly used in oil and gas well fracturing layer acidification or layer, interlayer and oil and gas wells within the temporary plugging, with filtration efficiency, formation protection layer, the liberation of the low permeability layer, but also with drilling fluid in the wellbore formation of ring wall, it need not acidizing perforating operation to remove and can be dissolved in crude oil and eliminated, so it is a deformable, oil soluble, oil reservoir protection of temporary plugging agent. It can not only used for drilling and completion, fracturing, acidizing, can also be used for oil well sand control. The construction process is simple, the effect of plugging is good, no damage to the oil layer. The product also has the role of anti inflation.

Two, technical requirements

 

Project	Index
Appearance	Light yellow or light brown suspension
Density，g/cm3	0.95～1.10
pH value	6～8
Oil soluble rate，%   ≥	95%
Solid content，%   ≥	20

Three, the use of methods
General site according to the need to use the concentration of 1%-10%. On the basis of the actual situation.

Four, storage and transportation
1 products stored in ventilated, dry place, prevent direct sunlight, far away from the fire source.
2 transport and handling should be handled gently and prevent violent collision, collision and inversion.

Five, matters needing attention
In the use process, the staff shall wear labor protection supplies, to prevent products splashed into the eyes or contact to the skin, once the occurrence of the above phenomenon, immediately wash with plenty of water, in serious cases, timely medical treatment. Sprinkle on the ground should be as far as possible, for a small number of products with soil landfill, you can also use a large amount of water to wash, wash water into the waste water system.
