1. Main characteristics and classification of casing heads Casing head, also called coupling head, is an important wellhead device. It is mainly composed of casing joint, environmental protection body, packing body and sealing gasket. The main function of the casing head is to connect the casing and make it tightly fixed on the wellhead device, thereby protecting the casing, preventing the wellhead mud from flowing back, and controlling the oil and gas flow. According to different structures and functions, casing heads can be divided into many types, such as ordinary casing heads, press-lock casing heads, bimetal casing heads, hot-insertion casing heads, hanging casing heads, etc. Among them, the pressure-locked casing head is currently the most widely used. It uses special pressure mechanics principles to form a special pressure connection between the casing and the wellhead device, thus ensuring the sealing and stability of the casing. sex.   2. The importance of casing heads in oil exploration and development As mentioned above, the casing head plays a vital role in oil exploration and development. It not only protects the casing, prevents wellhead mud backflow, controls oil and gas flow, etc., but also improves oil and gas production efficiency and reduces production costs. Therefore, in petroleum exploration and development, the selection, installation and maintenance of casing heads are very important tasks. In terms of casing head selection, it is necessary to comprehensively consider the type of wellhead device, working environment, working pressure, oil and gas production and other factors to select the most suitable casing head. In terms of installation and maintenance of casing heads, it is necessary to strictly follow relevant standards and specifications to ensure the sealing and stability of the casing heads.    

Casing Centralizer 1. API single piece casing centralizer performs satisfactorily in open hole as well as cased hole. 2. These high quanlity product,developed to meet and exceed API 10D specifications for use in highly demanding downhole conditions. 3. Single piece casing centralizer combines the highest restoring force with zero start force and zero running force. 4. The bow spring casing centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells. 5. The single piece centralizers reduce the effect of channelling by improving the cement flow,the results in more uniform cement thickness in the well bore. 6. By reducing the pipe movement before cement sets in.The single piece casing centralizers are able to minimize gas channelling. 7. The single piece centralizers are one piece construction in special high strength steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions. 8. The single piece casing centralizers are available in size 4-1/2" to 20". 9. Any special sizes or combination can be available on requirment. 10. This centralizer undergoes a special Iron Phosphate coating process to prevent it from rust and coated with special Polyester Powder. 11. It is shipped in assembled condition only. 12. When shipping them,in order to save space and shipment charges for customers,we usually put the smaller size centralizer into bigger size centralizer.   Parameter Model (in) Hooping In-Dia.

API Cement Head The API cement head is an essential tool used in the oil and gas industry for cementing operations. It serves as a connection between the cementing line and the top of the casing, facilitating the efficient and precise placement of cement slurry during well cementing processes. Available in sizes ranging from 4 1/2" to 20", the API cement head is designed to withstand high-pressure cementing applications, ensuring reliable and secure cementing operations. Along with its robust construction, the API cement head features a top swivel joint for easy installation and removal, enhancing operational efficiency. The design includes a plug dropping mechanism, which aids in the controlled release of cement plugs into the wellbore, contributing to optimal cementing performance. With a focus on safety and effectiveness, the API cement head is engineered to meet industry standards and specifications, making it an indispensable component in achieving successful wellbore cementing.   Specifications, mm Φ139.7 Φ177.8 Φ193.7 Φ244.5 Φ273 Φ339.7 Overall-length,mm 1950 2020 2020 2360 2360 2440
