•Oil-soluble temporary plugging agent
The main product is sdkx–5000y-o oil-soluble temporary plugging agent, which can be ched dissolved in 50-160℃ crude oil (specific temperature range is set according to oil well temperature), the dissolution time is 60-180 minutes, compressive strength: more than 45mpa
•Water-soluble temporary plugging agent
The main product is sdkx–5000y-w water-soluble temporary plugging agent, which can dissolve 90-95% in 50-160℃ water (the specific temperature range is set according to the oil well temperature) for 60-180 minutes. The remaining 5-10% of b-layer material is floating on the water surface in emulsion state and does not block the equipment. If there is an oil layer above the water, the residual emulsion will be completely dissolved. Compressive strength: more than 45mpa
The outstanding advantages are: because of the existence of laminated structure, it not only has a high compressive strength of more than 45Mpa in the dry solid state at room temperature and pressure, but also maintains a high compressive strength in the oil well reservoir; This is difficult for ordinary temporary plugging agents, especially water-soluble temporary plugging agents. Although they have high strength in dry solid state at room temperature and pressure, they will become soft in water above 45℃, lose their compressive performance and the ability of temporary plugging diverter when they really need to withstand pressure in oil well reservoirs.
The oil-soluble SDKX– 5000Xy-O series and water-soluble SDKX–5000Y-W series can be divided into different temperature subdivision types according to the different dissolution temperatures under these two kinds of trees.
Oil soluble temporary plugging agent SDKX–5000XY fracturing temporary plugging agent a series of product classification,according to the different temperature of the oil well type selection：
• SDKX–5000XY temporary plugging agent for fracturing— Suitable for oil well temperature 50℃-65℃ oil Wells (shallow oil Wells)
• SDKX–5000XY-O2 temporary plugging agent for fracturing— Suitable for oil well temperature 60-80 ℃ oil well; (Deep well)
• SDKX–5000XY fracturing temporary plugging agent— Suitable for oil well temperature 80℃-180℃ oil well. (Deep well and gas field pipe fractures)
SDKX–5000XY temporary plugging agent can dissolve in the mixture of oil and water in the corresponding temperature range after construction. The temperature of oil well is generally 60-120℃. It can automatically remove plugging agent and completely dissolve plugging agent in the temperature range of oil field. Existing voids and fractures are temporarily plugged and new fractures are stimulated in a different direction from the original fracture
Water-soluble temporary plugging agent SDKX–5000XY fracturing temporary plugging agent is classified into a series of products, and the types are selected according to different temperatures of oil Wells：
• SDKX–5000XY fracturing temporary plugging agent — Suitable for oil well temperature of 50-65℃ (shallow oil well )
• SDKX–5000XY fracturing temporary plugging agent — Suitable for oil well temperature of 60-80℃; (Deep well)
• SDKX–5000XY fracturing temporary plugging agent — Suitable for oil well temperature 80-180℃ oil well. (Deep well and gas field pipe fractures)
SDKX–5000XY temporary plugging agent can dissolve in water in the corresponding temperature range after construction. The temperature in oil well is generally 60-160℃. It can automatically remove plugging agent and completely dissolve plugging agent in oil field temperature range. Existing voids and fractures are temporarily plugged and new fractures are stimulated in a different direction from the original fracture.
