Applications and functions of wet fountain fittings used in pre-salt cluster of santos basin

Abstract

"Fountain fitting " - deep and ultra- deep in the waters oil and natural dig it up removal for needed which is main underwater of equipment is one Petrobras well in Brazil the mouth with (Wet Christmas Tree – fountain armature ) between WCT installed (Production Adapter Base - production adapter base ) (PAB) . This equipment is a wellhead equipment used to install oil and gas wellhead, control it and control the mode of operation. There are Fontan fittings for surface (for wells drilled on land) and subsea (offshore wells). According to its construction, it is horizontal and has three steps. Fountain accessories consist of tube and belt head, Christmas tree fountain. The belt head located at the bottom of the fountain shield is used to hang the protective belt, close the gap between the pipes, etc. It is for the Pipe head to hang and seal the pump compressor pipe lowered into the well attached to the belt head. The resource head directs the product from the well to the discharge line, enabling control and monitoring of the well. The fountain armature is equipped with a pressure gauge and thermometer. BOP and fountain of the armature absolutely different equipment that it is clarify need a lot people this two underwater equipment mix it up because it can each two of them the well in the mouth is installed . Dump Blow-Out Preventer (BOP) of wells digging , completion and processing during use which is security equipment . His main components drawers (rams), annular discharge against preventers and suffocation and don't kill are lines (choke & kill lines). Fountain pipes are lowered into the well where the fountain is expected to shoot. It is necessary to hang these pipes from something at the wellhead and direct the product of the well to the outside through it, and for this, it is necessary to mold the space between the fountain pipes and the production line. In order for the fountain to pump in an optimal mode, to regulate the use of reservoir energy, it is necessary to create counter pressure at the well mouth by any means. Therefore, the equipment at the mouth of the fountain well must be able to create any back pressure in the discharge line, including closing the well. In addition, the wellhead equipment should allow to measure the pressures behind the pipe, in the discharge line, and also to inject gas or liquid into the well if necessary.
