Christmas Tree & Tubing Head Christmas Tree: is an assembly of valves, spools and fittings for an oil well, and to design to direct and control formation fluids from the well. It can provide inlet for production tubing strings, including all components above the tubing head adapter. Christmas tree assemblies can constitute many different kinds of combinations in order to meet any special requirement. Based on their different functions, Christmas trees can be classified into such special Christmas trees as oil production (flowing and artificial lift) Christmas trees, gas (natural gas and various sour gas) production Christmas trees, water injection Christmas trees, thermal recovery Christmas trees, fracturing Christmas trees and acidizing Christmas trees. Different pressure ratings serialize Christmas trees. The gas production Christmas tree and tubing head are mainly used to produce gas and inject gas. The relative density of natural gas is low and gas column pressure is low, while well head pressure is high and liable to leakage regardless of gas production and gas injection. Sometimes natural gas contains corrosive media such as H2S and CO2. Therefore, the gas production Christmas tree calls for rigid requirements on both its materials and its sealing characteristics. For the sake of safety, two gate valves are used on the tubing and casing respectively. Some gate valves to be used on high pressure and ultra-high pressure gas wells are integrated valves manufactured from high quality forged steel. The pressurization parts of the Christmas trees and tubing spools sold by Sapwells Global are made of forged or special smelted forging, so it is high-pressurization safety and so on. Scope of supply: Working pressure: from 2,000psi to 20,0000psi Nominal diameter: from 2.1/16" to 5.1/8" Working medium: crude oil, gas, drilling fluid, gas contained H2S, CO2 Working temperature: -46 C to 121 C (L U) Material class: AA, BB, CC, DD, EE, FF Specification level: 1-4 Performance requirement: 1-2 To complete with air or hydraulic safety valve at option. 3 www.sapwellsglobal.com
Tubing Spool 1. Tubing head structure Tubing head is usually a spool with both flanged ends, which is set on the top flange of casing head to hang tubing hanger and seal the annular space between the tubing string and oil-layer casing and which consists of tubing head spool and tubing hanger. 2. Functions: 1) Hang the tubing string inside well; 2) Seal the annular space between tubing and casing; 3) Give a crossover to connect casing head downwards and to connect Christmas tree upwards; 4) Provide both side outlets in tubing head spool body through which to execute injection and wellwash operation. 3. Tubing hanger Tubing hanger is an assembly to support tubing string and seal the annular space between tubing and casing, which is connected with tubing and seated into tubing hanger spool by tubing gravity. It is convenient to operate and replace wellhead so that it is widely used for intermediate depth well and common well. Design features: Fabricated with BT secondary seal, and could be field mounted by cutting casing pipe to accommodate the seal height. Tubing hanger and top flange are designed to run cable through. Several control ports are available for connecting pipeline. Sapwells Global sells tubing head spool manufactured in full accordance with API 6A, the body is made of forged or special smelt steel, providing high bearing strength, safety and reliability. Side outlets could be line pipe thread or studded, studded side outlet is machined with 1. 1 / 2 " female thread. 4 www.sapwellsglobal.com
