Abstract
The invention relates to a novel wellhead and oil-producing tree for steam stimulation in viscous crude oil production, comprising a casing head shell, a slip-type hanger, a tubing-head cross, a brake valve, a tubing hanger, a middle steel ring, an adapter flange, a blowout preventer, a sealer and a stop valve. The slip-type hanger is located on the casing head shell, and the tubing hanger is located on the tubing-head cross, and both of which are fixed by top threads; the tubing hanger and the adapter flange are sealed by the middle seal ring and connected by a bolt; bolt connection is respectively adopted between the casing head shell and the tubing-head cross, between the tubing-head cross and the brake valve, between the adapter flange and the blowout preventer, between the blowout preventer and the sealer as well as between the blowout preventer and the stop valve; the casing head shell and the slip-type hanger form a slip-type high-temperature casing head structure; the middle seal ring and a metal gasket ring sealing structure are arranged between a tubing head and the adapter flange; and the oil-producing tree part is provided with a long-plunger blowout preventer. The utility model solves the problem that the general thermal production well has simple well completion without blowout prevention function in the prior art, thus being widely used for the steam stimulation operation of the viscous crude oil production.
Description
Technical field:
The utility model relates to a kind of viscous crude exploitation steam the handle up a kind of novel wellhead assembly and the production tree of usefulness.
Background technology:
At present, domestic oil-field thick-oil exploitation is mainly adopted conventional thermal production well mouth with well head, and this well head completion mode is single, does not have the blowout prevention function, and current urgent need exploitation is a kind of to be used for the casing head completion, and has the novel wellhead assembly and the production tree of blowout prevention function.
The utility model content:
The purpose of this utility model provides a kind of novel wellhead assembly and production tree, and it is simple that this device and production tree have solved the conventional thermal production well completion mode that exists in the prior art, does not have the problem of blowout prevention function.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel wellhead assembly and production tree, by the casing head housing, slips hanger, the tubing head four-way, gate valve, boll-weevil hanger, middle steel ring, adapter flange, preventer, sealer, stop valve is formed: the slips hanger seat is on the casing head housing, the boll-weevil hanger seat is all fixed with jackscrew on the tubing head four-way, steel ring sealing during boll-weevil hanger and adapter flange are used, bolt connects, casing head housing and tubing head four-way, tubing head four-way and gate valve, adapter flange and preventer, preventer and sealer, preventer all is connected with bolt with stop valve; Casing head housing and slips hanger constitute slip-type high temperature CASINGHEAD STRUCTURE, and hang adopts slips to hang, and encapsulant adopts exotic material, steel ring and metal gasket ring hermetically-sealed construction in being provided with between tubing head and adapter flange; Partly be provided with the long-plunger preventer production tree, can under the situation of not carrying polished rod, finish closing well, hold polished rod in off position tightly and realize sealing, plunger forward end seal semicircular in shape.
The beneficial effects of the utility model are: because this device and production tree are provided with slip-type high temperature casing head, and the pressure of suspension sleeve post and Sealed casing pipe intercolumniation reliably; Between tubing head and adapter flange, adopt dual metallic seal, high temperature resistant, high pressure resistant; Production tree partly is provided with preventer, can realize closing well under the situation of not carrying polished rod.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, the casing head housing, 2, slips hanger, 3, the tubing head four-way, 4, gate valve, 5, boll-weevil hanger, 6, middle steel ring, 7, adapter flange, 8, preventer, 9, sealer, 10, stop valve.
