China Filling resin for oil fields manufacturer

In the field of oilfield development in China, resin filling is a crucial engineering material that plays an irreplaceable role in many key processes such as sand control, bottom water plugging, and cementing in oil wells. The curing time of the filling resin for oil fields is not only directly related to the efficiency and effectiveness of construction, but also has a profound impact on the quality and long-term stability of the entire oilfield project. Next, let's take a look at the curing time of filling resin used by China filling resin for oil fields manufacturers.

1. Sand control operation:

In oil well sand control technology, the curing time of filling resin for oil fields is a key parameter. For example, in a certain study, when the dosage of curing agent is 6% to 8% of epoxy resin, the curing time is about 0.5 hours. However, in practical applications, the curing time may vary due to factors such as resin type, curing agent dosage, and formation temperature. Another study suggests that at 60 ℃, the curing time of the resin may be extended to 24 hours to meet the requirements of on-site construction, while ensuring that the compressive strength and permeability of the solid body reach the desired level.

2. Casing plugging:

For casing plugging operations, the curing time of the filling resin for oil fields needs to be precisely controlled to ensure the construction effect. The solidification time of liquid resin used for casing plugging in Changqing Oilfield at 60 ℃ is 4.5 hours, which ensures the fluidity of the resin during injection into the target layer and sufficient solidification in the target layer, thus forming a strong plugging barrier.

3. Blocking operation:

In the sealing operation, the curing time of the resin also needs to be adjusted according to specific requirements. For example, in the bottom water plugging operation of T Oilfield in the west, the gel curing time of filling resin for oil fields rubber plug material is controlled between 3 and 5 hours to meet the requirements of construction time and migration time of resin material in the well section. Another study suggests that at 90 ℃, the curing time of phenolic resin remains stable between 3 and 9 hours, which ensures safe injection and effective curing of the plugging agent solution.

4. Other assignments:

In addition to sand control and plugging operations, filling resin for oil fields is also widely used in other fields of oil fields, such as cementing, fracturing, etc. In these assignments, the curing time of the resin also needs to be adjusted according to specific process requirements. For example, at an ambient temperature of 45 ℃, the initial curing time of resin sand is 30 minutes, while the final curing time may be as long as 96 hours to meet the needs of different construction stages.
China filling resin for oil fields manufacturers have demonstrated a wide range of product choices and excellent technical strength in the key performance indicator of curing time. Different manufacturers provide diverse and high-performance filling resin for oil fields products for oilfield engineering based on their own research and development advantages and production processes. These products, with their reasonable curing time settings, can meet the usage needs of different oilfield environments and construction requirements, effectively ensuring the smooth progress and high-quality completion of oilfield engineering.
