A Christmas Tree comprises a series of valves, spools, a choke, and connection. It used for production or injection wells such as oil wells, gas wells, water injection wells, water disposal wells, etc. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations.

Wellheads are equipped with fail-to-safe safety valves, whose design varies depending on the system. These safety valves are controlled via the Surface Wellhead Control Panels — and in an emergency, the Emergency Shutdown Panels assume the control function. The hydraulic functions can be combined for the sequential closing in compact units via the modular Maximator Surface Wellhead Control Panels.

All About Christmas Tree Valves

Now, my company is achieving great success and huge profits. My students always tell me that "you know exactly what we need", and this encourages me a lot to start a career as an Online instructor. Pressure sealing and isolation between casing at surface when many casing strings are used. Disposal PCP Well. K and U are the largest and overlap the other ranges.

Christian Cavallo. This feat is accomplished by humble tools such as valves , which are devices that can regulate fluid flow through a system via mechanical or electromechanical means. Valves can perform many tasks; our article on understanding valves shows just how varied and multipurpose they can be. The goal of this article is to highlight one important valve system in the fuel industry, the Christmas tree valve , and its function, construction, and specifications. Through this investigation, this article aims to help buyers understand what Christmas tree valves are, how they work, and how to choose the correct system for the job at hand. Christmas tree valves are a system of valves, chokes , spools , and gauges which, unsurprisingly, resemble a Christmas tree.

PEH:Introduction to Wellhead Systems

A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment. While drilling the oil well, surface pressure control is provided by a blowout preventer BOP. If the pressure is not contained during drilling operations by the column of drilling fluid , casings, wellhead, and BOP, a well blowout could occur. When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree , which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production.

Guice, W. Mathematical modeling and test data were used to predict the temperatures ofequipment in API fire testing. The thermal response of these systems is used toselect critical parts for fire-resistant equipment. Conditions of internalcomponents were found to be calculable on the basis of defined testcriteria.

In the complicated but vital industry of drawing oil and gas out of the earth and getting it to the surface, people often get confused about the difference between a Christmas tree assembly and a wellhead. Although the terms are used interchangeably, they are not the same piece of equipment.

Christmas Tree is connected to the top of the tubing and cemented to the top of the casing. The Christmas tree is the heart of the offshore hydrocarbon production system. It is the primary means of the well control and plays a key role in the emergency shut down system. The Christmas tree sits on the top of the wellhead casing system and represents the interface between the well and the production and process facility. The Christmas tree consists of an assembly of a gate valve that controls the flow of hydrocarbons.

Но ТРАНСТЕКСТ не был обычным компьютером - его можно было отформатировать практически без потерь. Машины параллельной обработки сконструированы для того, чтобы думать, а не запоминать. В ТРАНСТЕКСТЕ практически ничего не складировалось, взломанные шифры немедленно отсылались в главный банк данных АНБ, чтобы… Сьюзан стало плохо. Моментально прозрев и прижав руку ко рту, она вскрикнула: - Главный банк данных. Стратмор, глядя в темноту, произнес бесцветным голосом, видимо, уже все поняв: - Да, Сьюзан. Главный банк данных… Сьюзан отстраненно кивнула. Танкадо использовал ТРАНСТЕКСТ, чтобы запустить вирус в главный банк данных.

Пуля срикошетила от стены. Рванувшись вниз за своей жертвой, он продолжал держаться вплотную к внешней стене, что позволило бы ему стрелять под наибольшим углом. Но всякий раз, когда перед ним открывался очередной виток спирали, Беккер оставался вне поля зрения и создавалось впечатление, что тот постоянно находится впереди на сто восемьдесят градусов.

Игра в шарады закончилась. Дело принимает совсем дурной оборот. - Итак, кольцо взял немец. - Верно. - Куда он делся.
