HTHP Fluid Loss Tester (HTHP Fluid Loss Cell for Cement Slurry)

NJSJ2017 HTHP Fluid Loss Tester is a professional Fluid Loss Tester designed for accurate measurement of cement slurry fluid loss under high temperature and high pressure conditions. It is widely used in oilwell cementing laboratories for cement slurry formulation development, additive evaluation, and quality control testing.

Also known as an HTHP Fluid Loss Cell or HTHP Fluid Loss Tester, this instrument is mainly used to hold cement slurry and enable filtrate to pass through filter screens, providing reliable filtration loss results for oilfield cementing applications.

Model: NJSJ2017
Type: HTHP Fluid Loss Tester / HTHP Fluid Loss Cell
Application: Cement slurry filtration and fluid loss testing
Testing Standard: API Spec 10 A

1. What Is a Fluid Loss Tester Used For?

A Fluid Loss Tester is used to measure the amount of filtrate that escapes from a cement slurry under specific temperature and pressure conditions. This test helps cementing engineers evaluate cement slurry fluid loss performance and ensure the slurry can maintain stability during pumping and placement in the wellbore.

The NJSJ2017 HTHP Fluid Loss Tester is mainly used for oilwell cement slurry testing, especially in applications requiring filtration evaluation at high temperature and high pressure.

Typical applications include:

• - Cement slurry fluid loss performance evaluation
• - Testing fluid loss additives (cement filtration control additives)
• - Cement slurry formulation optimization for HPHT wells
• - Quality control testing for cementing service companies
• - R&D testing for cement slurry systems under harsh downhole conditions

2. Key Features of NJSJ2017 HTHP Fluid Loss Tester

Newly Designed Fluid Loss Cylinder (Less Blockage, Easy Cleaning)
The NJSJ2017 HTHP Fluid Loss Cell adopts a newly designed fluid loss cylinder, which can effectively reduce the risk of blockage during the filtration process. It is also easier to clean after testing, improving laboratory efficiency. 

Quick-Disconnect Connector for High-Pressure Gas Passage
A quick-disconnect connector is used for high-pressure gas passage connection. This design improves connection safety and makes operation faster compared with conventional threaded connections. 

Durable Filter Screen with New Technique
With a new manufacturing technique, the filter screen is more durable and provides improved performance for repeated filtration testing. 

Built-In Timer and Alarm Function
The instrument is equipped with a timer and alarm system. The alarm sound can also be turned off easily, providing more convenient lab operation. 

Stainless Steel Surface for Corrosion Resistance
The surface of the instrument is made of stainless steel, improving durability and corrosion resistance for long-term use in cement testing laboratories. 

3. Filter Screen System (60 Mesh + 325 Mesh)

The NJSJ2017 Fluid Loss Tester uses a dual filter screen structure for reliable filtration testing:

325-Mesh Filter Screen
Mainly used to hold up cement slurry and enable the fluid to pass during filtration.

60-Mesh Filter Screen
Mainly used to support the 325-mesh filter screen and increase the strength of sintered filter screens during filtration.

This design improves filtration stability and reduces the risk of filter damage during high-pressure testing.

5. Quick-Disconnect High Pressure Connection (Safer and Faster)

The connector for the high-pressure manifold and the connector for high-pressure gas passage are connected by a pin. Users can complete the connection through three simple steps. Compared with threaded connections, this design provides tighter and safer connection performance. 

Connection Steps:
1. Connect and fasten the end cap, valve, and connector for high-pressure gas passage.
2. Insert the connector for high-pressure gas passage into the connector for high-pressure manifold (no need to screw down).
3. Insert the pin into the hole to complete the connection. 

This design improves operation efficiency and reduces safety risks during high-pressure testing.

6. Typical Applications: Cement Slurry Filtration Control and Additive Evaluation

The NJSJ2017 Fluid Loss Tester is suitable for testing various oilwell cement slurry systems, including:
- API Class G cement slurry systems
- High temperature cement slurry systems
- Salt-resistant cement slurry systems
- Cement slurry systems containing dispersants and retarders

7. Why Fluid Loss Testing Is Important in Oilwell Cementing

Fluid loss control is one of the key factors affecting cement slurry stability and wellbore isolation quality. Excessive filtration may lead to:

• - Slurry dehydration and thickening too early
• - Poor displacement efficiency
• - Reduced cement sheath integrity
• - Gas migration and channeling risk

By using an HTHP Fluid Loss Tester, laboratories can evaluate slurry fluid loss behavior under realistic temperature and pressure conditions and optimize slurry design accordingly.
