Abstract
The utility model discloses an integral type casing head single-barrel twin-well well head device which comprises an integral type casing head (6), a double-hole base (5), a tubing head (7), a tubing head adapter flange (8) and a Christmas tree (9). The double-hole base (5) are located on a water partitioning guide pipe (1), the integral type sleeve head (6) is mounted above the double-hole base (5), the tubing head (7) is mounted above the integral type sleeve head (6), the tubing head adapter flange (8) is mounted above the tubing head (7), the Christmas tree (9) is mounted above the tubing head adapter flange (8), and the well head device is integrally formed. Two independent wells are drilled out by utilizing the same small water partition guide pipe, and production between the two wells is free of mutual interference, platform space is saved, drilling operation is simple, and oil production is more convenient.
Description
Technical field
The utility model relates to oil well drilling device, is specifically related to a kind of Integral casing head monotubular twin-well wellhead assembly.
Background technology
At present, known monotubular twin-well wellhead assembly, the bottom basal disc is monolithic, casing head and above be split-type structural, this monotubular twin-well wellhead assembly at sea reaches in the onshore oil field exploitation, always wishes to have necessarily the well slot than large space, satisfy back-to-back two mouthfuls of spaces that well occupies, but always wish to bore more producing well at limited platform jacket for offshore platform, can save cost like this, improve development benefit.
Summary of the invention
The purpose of this utility model is: a kind of Integral casing head monotubular twin-well wellhead assembly is provided, utilizes same less riser pipe, get out two independently wells, and do not interfere with each other on producing between the well, save platform space, drillng operation is simple, and recovering the oil, it is more convenient to produce.
The scheme of the utility model technical solution problem is: this wellhead assembly comprises Integral casing head, diplopore pedestal, tubing head, tubing head crossover flange and production tree, the diplopore pedestal is seated on the riser pipe, Integral casing head is installed in above the diplopore pedestal, tubing head is installed in above the Integral casing head, the tubing head crossover flange is installed in above the tubing head, production tree is installed in above the tubing head crossover flange, whole formation wellhead assembly; Wherein, two holes that seal with axle formula hanger prolongation neck are left in the bottom of Integral casing head, and are designed with two independently pressure testing holes; The top of Integral casing head is left and can be satisfied the shoulder that two casing hangers are sat extension simultaneously; Integral casing head adopts connecting bolt to be connected with the diplopore pedestal, and Integral casing head adopts the studding bolt to be connected with tubing head; Be designed with four whorl side outlets on the Integral casing head.
The utlity model has following advantage: 1. Integral casing head is installed on above the diplopore pedestal, two cover well heads are installed among the same less riser pipe simultaneously, two production trees of monotubular twin-well adopt the mode of mutually cutting edge to install to satisfy each own enough space, it is very near that the center of two well heads is leaned on, guarantee phase mutually noninterfere between each valve, structure is compact; 2. the bottom design of Integral casing head has two pressure testing holes, can carry out leakage test to two casing hangers respectively, guarantees the reliability of sealing; 3. two of Integral casing head independently well head all be designed with two side outlets, be used for the drilling process circulating mud; 4. casing head adopts global design, has reduced the height of well head, has saved the space of platform, has saved the time that well head is installed.
