Casing cementing tools   Casing cementing tools are also called cementing hardware, which include centralizers, stop collars, float equipments, cementing plugs, stage tools and scratchers. They are mechanical devices commonly used in running pipe and in placing cement around casing.   Floating equipment is commonly used on the lower section of the well casing Some basic types of floating and guiding equipment are: 1. The guide shoe, with or without a hole through the guide nose. 2. The float shoe, containing a float valve and a guide nose. 3. The float shoe and float collar, containing an automatic fill-up valve.   Plug containers hold the top and bottom cementing plugs, and come in two different versions: continuous cementing head and quick-change container. Centralizers: Centralizing the casing with mechanical centralizers across the intervals to be isolated helps optimize drilling-fluid displacement. In poorly centralized casing, cement will bypass the drilling fluid by following the path of least resistance. Two general types of centralizers are: 1. Spring-bow 2.

The cement head is a very important device in cementing operations, it may affect the cementing quality. Therefore, the cement head needs to be tested after leaving the factory. What should the cement head be tested for?   (1) Dimensional inspection of cement head The first thing to test is whether the size of the cement head is qualified. There are many types of cement heads, and each type of cement head has many sizes, so it is very necessary to test the size of the cement head. There are two main purposes for testing the size of the cement head after it is produced: -one is to check whether the size of the cement head meets the specified standards; -the second is to check whether the size of the cement head is the size required by the customer.   (2) Detection of cement head connecting threads The thread inspection should according to the inspection standards. Different types of cement head have different thread inspection standards. If other forms of connecting threads are used, other inspection standards need to be used.   (3) Inspection of the overall sealing performance of the cement head The sealing performance test of the cement head is also one of the very important testing contents. It mainly uses clean water to conduct the sealing performance test to see whether the test pressure meets the sealing test pressure regulations. The rotating cement head is also used for rotation performance testing.   (4) Cement head material testing In addition to the above inspections of cement heads, the materials of stressed parts must also be inspected. The main inspection contents include tensile strength testing and hardness testing of metal materials used in parts subjected to tensile loads, and parts subjected to impact loads. The metal materials used are tested for impact energy absorption, etc. After the inspection of the cement head is completed, a mark needs to be placed on the obvious position of the cement head, including product model, working pressure, manufacturer name or registered trademark, product number and date of manufacture, etc.   Strict testing,meets the standards and customer standards, and the market is the only criterion for testing products. Puyang Zhongshi Group has more than 20 years of experience in producing cementing accessories, and its products sell well at home and abroad. 

Reamer Shoes are composed of aluminum eccentric toe cap and body.

In Henan, China, on Aug 28, 2023, Puyang Zhongshi Group, a renowned manufacturer and supplier in the oil and gas industry, is excited to unveil its latest product line – high-quality sucker rod centralizers designed to optimize well performance. As a trusted original equipment manufacturer (OEM), Puyang Zhongshi Group takes pride in delivering superior products while maintaining a competitive edge in both service and pricing. API standard sucker rod centralizer   Sucker-rod centralizers also may be called paraffin scrapers or rod guides. They keep the rods and couplings away from the tubing to decrease wear. However, special mechanical paraffin scrapers have been developed to also aid in keeping paraffin off the tubing and most of the sucker-rod length.   Rod centralizers with full-bore-fluted centralizers should be placed on or between the pump-handling pony rod, the sinker bars used above the pump, and the first two sucker rods above the sinker bars. Rod centralizers in these locations help stabilize the pump and valve rod and prevent valve-rod bending or breakage. When a tubing anchor is not used, rod centralizers will reduce tubing wear because of tubing helical buckling on the upstroke. Rod centralizers also may be used in crooked holes in which there are areas of concentrated tubing wear. working principle:   It connect with sucker rod, the centralizer casing OD is larger than the sucker rod coupling OD in order to centralizer rod. Centralizer casing has high strength wear resistant, so when contact with oil tube, makes the centralizer body wearing and reduces oil tube wearing so as to anti-wear (centralizer casing temperature resistant: 260°C, material: self-lubricating Ni-p plating material). The steel surface adopt Ni-p plating (the anti-corrosion technology) makes the centralizer has the ability of anti-wear and anti-corrosion. And it also suitable for the worse corrosion well condition.   Sucker rod centralizers play a crucial role in ensuring efficient oil extraction by providing proper alignment and spacing of sucker rods within wellbores.
