Low permeability reservoirs are vulnerable to capillary imbibition when foreign fluids, such as drilling fluids, drilling additives, fracturing additives, and other liquids, enter the process of exploiting low permeability oil and gas fields because of the high content of argillous cement, high water saturation, high capillary pressure, poor permeability, complex structure, serious heterogeneity, and natural crevices. Low permeability oil and gas fields are impacted by the inability of the foreign fluid that invaded the reservoir to flow back, which causes water lock damage and a reduction in reservoir permeability. In order to decrease or prevent water locking damage, safeguard the reservoir, and boost production, waterproof locking agents must be used during the exploitation of low permeability oilfields. 

This product can alleviate the water lock damage by successfully reducing the interfacial tension of the held liquid and increasing the drainage speed. In the process of exploiting low permeability oil and gas resources, it can effectively avoid and relieve reservoir damage caused by water phase intrusion, prevent water lock damage, and boost oil well production.

The technical indexes of Waterproof lock agent should meet the requirements in Table 5. 

Oil well fracturing, acidification, well washing, and other processes frequently use fracture drainage assistance, which can stop fluid and crude oil from emulsifying. This product can enhance the hydrophilicity of rock, prevent and break the formation of an emulsion between the liquid and crude oil, facilitate the easier discharge of spent liquid from the formation following work, lessen reservoir damage, and enhance the construction effect by lowering surface tension and flow resistance of liquid in the core throat. It is easy to use, has good compatibility, low dose requirements, high cost-performance, resistance to salt and temperature, and more.

The fracturing aid technical indicators must to satisfy the specifications listed in Table 6.

Iron complexing agent, iron reducing agent, and other ingredients make up iron ion stabilizer, a colorless or pale yellow liquid. By successfully complexing free iron ions, iron ion stabilizer can be added to acidic solutions to prevent residual liquid from producing iron hydroxide precipitate in the formation, which could cause formation clog damage owing to a fall in pH. Its primary applications include the formation acidizing fracturing process, the water injection system of oil and gas wells, the pickling operation of oil pipelines, the addition of hydrochloric acid and phosphoric acid mixture to various acidizing solutions, and soil acid.

The technical index of iron ion stabilizer shall meet the requirements in Table 7.

One type of high temperature stabilizer used in oilfield fracturing is the pH regulator. The fracturing fluid needs to have good rheological qualities throughout the construction process in order to guarantee the successful application of sand fracturing. The temperature resistance and viscosity retention of the liquid can be significantly enhanced by the stabiliser used in hydraulic fracturing.

Principal applications: Modify pH level; utilize standard hydroxypropyl guaculars at low concentration limits to maximize gumming efficiency; lower the dose of guaculars fracturing fluid thickening or crosslinking agent; lessen fracturing fluid residual damage to the formation goal.

Table 8's requirements should be satisfied by the pH regulator's technical specifications.

Water-based or emulsified fracturing fluids can cause formation damage; this is why break agents are used to reduce this damage and decrease the viscosity that the fluids maintain. While it is challenging for traditional rubber breakers to meet all of the requirements at once, the company's capsule rubber breakers not only perform well in terms of water isolation and delayed rubber breaking, but they also release ammonium persulfate through external force and dissolution in the oil formation conditions. This can enhance the permeability of the proppant layer and give the fracturing fluid exceptional flowback characteristics and excellent rheology. In addition, the chosen film material is soluble and biodegradable, and the capsule breaking agent's granules are homogenous and smooth.

The technical indexes of ammonium persulfate capsule breaker should meet the requirements in Table 9.

This product combines the properties of produced water from oil and gas fields and the reuse rate of produced water. Compared with the traditional powder drag reducer liquid preparation construction mode,   there is no need to mix the liquid beforehand and no need for a mixing workshop. This results in a significant reduction in the labor intensity of liquid mixing, a cost reduction of over 70%, and a 20% increase in construction time.

The technical indexes of fracturing fluid drag reducer should meet the requirements in Table 10.

As an oil field develops, scale formation will become more and more problematic due to the oil well's gradually increasing water content. This will disrupt the flow of oil and gas, lower the permeability of the reservoir, lower the oil well's injection and output capacity, and even break down equipment, all of which will have a negative impact on the field's ability to be exploited. To prevent the creation of scale, adding a scale inhibitor is currently one of the most effective ways.This product reacts chemically with various heavy metal ions in water at room temperature and in a range of pH values, producing insoluble, low-water-content, easily-filtered, and flocculent precipitation in a short amount of time that effectively removes heavy metal ions from water. Phosphonic acid, Phosphonic carboxylic acid, Phosphonic acid, and polymer are the principal natural dispersants found in it.

Scale inhibitor technical specifications should meet the requirements in Table 11.

When it comes to developing carbonate reservoirs, acidification is one of the most efficient technical solutions for raising water injection and oil and gas well production. Corrosion inhibitors, as the name suggests, are agents or compounds that are used in production to prevent or slow down chemical corrosion. This is because severe acid corrosion in oil wells necessitates their use. The performance of acidizing corrosion inhibitor is subject to higher standards due to its role as the primary concentration agent. The compound system with ketone aldehyde-amine condensation as the primary agent and the compound quaternary ammonium salt with pyridine and quinoline as the major agent are currently the main products of acidizing corrosion inhibitors.

Acidizing corrosion inhibitor technical indicators should meet the requirements in Table 12.
