#wellhead

The wellhead in the courtyard of the Ca d'Oro is one of the most beautiful wellheads in Venice. It was carved from a single block of red Verona marble by Bartolomeo Bon in 1427-28 and is ornately decorated with figures of Justice, Fortitude, and Charity, each flanked by lions and surrounded by fine acanthus leaves. This wellhead also has a fascinating history as it was removed from the palazzo and sold before Giorgio Franchetti rescued it from an antique dealer in Paris and returned it to its rightful place at the beginning of the 20th century. In 2019, it was repeatedly submerged under corrosive seawater during the exceptional high tides in November and December.

Now, thanks to Save Venice's Immediate Response Fund, this unique and resilient treasure is undergoing vital conservation treatment.

What are the Wireline tools and uses of the Wireline tools? The Wireline tools are in particular and expressively designed considered or planned tools and an instrument which is lower into a wellbore on the ends of the Wireline cables. There are some wireline tools that are used and facilitate in the oilfield too. The wireline tools are going to mention below are –: • Wireline tool string • Pulling tools • Slick line tools • Running tools • Wireline Grab

Wellhead is a common and usual period and time which is worn to express and explain the pressure-containing and accepting element or section at the platform of an oilfield oprtaions that offer and present the crossing point and line for drilling, completion, and testing of all coordinate procedure and process points.

The fracturing tree is a wellhead equipment used to direct and control oil & gas from the well. It is an assembly of valves, spools, and fittings used for an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well, and other types of wells. Christmas trees supplied by Finemade are used in oil exploration and production in surface. Christmas trees on surface wells are also known as surface trees, as they connect to the wellhead that is visible on the surface of a well.

 Features of Fracturing Tree:

It is input into fracturing head through several fracturing manifold. It is input into fracturing gate valve to perform fracturing production. It controls medium access through fracturing gate valve switch. Now, the fracturing tree manufactured by Douson has maximum drift of 7-1/16"and maximum pressure of 20000psi. The main part of our fracturing is fracturing valve which has acquired patent for national invention and patent for utility model. Fracturing technology adopted by Douson is internationally advanced technology.

 Application of frac tree:

After the oil well production reaches a certain stage, the production capacity and permeability are reduced. In order to enhance the oil discharge capacity and increase the oil well production, people have invented the fracturing technology. The fracturing method is divided into two types: hydraulic fracturing and high-energy gas fracturing. Hydraulic fracturing is to inject high-speed fluid into the well by the high-pressure pump trucks on the ground. The high pressure of the bottom of the well is used to break the cracks in the reservoir rock. In order to prevent the pump from stopping, the pressure drops and the cracks close themselves. In the injected liquid after the rupture of the formation, the sand is mixed with the sand several times larger than the density of the formation, and enters the crack together with the fluid, and stays in the crack forever. The crack is open, which improves the oil flow environment for a long time. The current hydraulic fracturing technology is very mature, and the oil well stimulation effect is obvious, and it has already become the common technology that people prefer. Especially for the oil flow channel is very small, that is, the oil layer with a lower permeability has a particularly strong effect.
