Abstract
The utility model discloses a multi-base quick-installation well head device. A casing spool (8) is arranged on the upper surface of a casing head (6); an oil pipe head (10) is arranged on the upper surface of the casing spool (8); an oil pipe conversion flange (12) is arranged on the upper surface of an oil pipe (10); the casing head (6) hangs a surface casing suspender (5) and seals a surface casing (4); a core shaft-type suspender (7) arranged inside the casing head (6) hangs and seals a technical casing (3); a well-completion core shaft-type hanger (9) arranged on the upper surface of the core shaft-type hanger (7) of the technical casing hangs and seals a well completion casing (2); and an oil pipe suspender (11) arranged on the upper surface of the core shaft-type suspender (9) of the well completion casing hangs and seals an oil pipe (1). The well head device has the advantages that the assembly and disassembly operation of a blowout preventer is carried out once during the whole installation process, the construction period is shortened greatly, the production cost is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to oil well drilling device, is specifically related to a kind of multi-base fast-assembling wellhead apparatus.
Background technology
At present, known most popular wellhead assembly is the multilayer wellhead assembly that superposes step by step, this traditional wellhead assembly is in drilling process, every dress one deck all needs to change the operation of the preventer of different size and the operation of being correlated with, consume great amount of manpower, goods and materials, inefficiency, the cycle is long.
Summary of the invention
The purpose of this utility model is: a kind of multi-base fast-assembling wellhead apparatus is provided, and this wellhead assembly only carries out the mounting or dismounting operation of a preventer in the whole erection process, greatly the reduction of erection time, reduce production costs, and increases work efficiency.
The scheme of the utility model technical solution problem is: each layer is designed to identical nominal size, before coming into operation, connect into each layer as a whole in advance, no longer take apart when installing and using, preventer is installed, each layer hanger and seal thereof are installed one by one by preventer at top layer.
This wellhead assembly comprises casing head, four-way junction of casing, tubing head, the hanger of tubing head crossover flange and each several part, four-way junction of casing is installed in above the casing head, tubing head is installed in above the four-way junction of casing, the oil pipe crossover flange is installed in above the oil pipe, hang and the sealing surface pipe by the surface pipe hanger on the casing head, the mandrel formula hanger that is seated in the casing head hangs and the Sealing Technology sleeve pipe, the completion casing mandrel formula hanger that is seated in above the protective casing mandrel formula hanger hangs and the sealing completion casing, be seated on the completion casing mandrel formula hanger and boll-weevil hanger hang and the sealing oil pipe.
In the multi-base fast-assembling wellhead apparatus of the present utility model, the emergent slips hanger of protective casing that is seated in the casing head hangs and the sealing oil pipe.
In the multi-base fast-assembling wellhead apparatus of the present utility model, the emergent slips hanger of completion casing that is seated in above the protective casing mandrel formula hanger hangs and the sealing completion casing.
In the multi-base fast-assembling wellhead apparatus of the present utility model, casing hanger and boll-weevil hanger are designed to identical external diameter, use a kind of preventer of specification.
The utlity model has following advantage: 1. integral installation, save time, reduce labour intensity; 2. only need a kind of preventer of specification, simplified operation, greatly reduce the fund of equipment cost; 3. the structure of multiple seat type has been reserved entry for the reply emergency that may occur everywhere again, is convenient to take apart from corresponding position various emergencies are taken appropriate measures, and the security performance of well head is guaranteed when simplifying the operation, reducing cost; 4. casing hanger adopts the structure of mandrel formula, design has the mud circulation groove around the periphery of hanger, be convenient to drilling well circulation fluid and well cementation circulation fluid routing up on every side from hanger, and hang and seal separately, be that first suspension sleeve carries out well cementing operation, and then lower seal mechanism seals, and this design can make the circulation fluid of multilayer sleeve drilling well in the same well head and well cementing operation all from same drilling spool well circulation.
