Description
Technical Field
The utility model belongs to the technical field of the metal seal, a compound multi-functional well drilling cross device of drilling and production integration is related to.
Background
The existing drilling four-way joint has single function and can not realize drilling and production operation, most drilling four-way joints are in single and split design, leakage points are more, and material cost is higher; maintenance and service costs are high. When the drilling and production operation functions are realized, the fact that the oil pipe hanger and the mandrel type casing hanger have basically the same sealing structure and sealing mechanism is considered at the same time, the sealing structure is a mixed structure of metal compression sealing and elastic rubber sealing, leakage is avoided due to the sealing structure, and the rubber sealing element of the ultrahigh-temperature well is well prevented from losing efficacy quickly. Under various external severe environments, the rubber part seal and metal seal combination greatly enhances the reliability of the sealed annular space, can ensure the long-term sealing and the later safety, and greatly reduces the safety risk for the well completion, oil extraction and gas production operations of ultra-deep, ultra-high pressure and ultra-high temperature wells and high sulfur-containing oil and gas wells.

The utility model provides a compound multi-functional well drilling cross device of drilling and production integration, it is sealed effectual, improved the effect of drilling and production.
The purpose of the utility model can be realized by the following technical proposal:
a drilling and production integrated composite multifunctional drilling four-way device comprises a drilling four-way body; drilling cross body upper portion is equipped with first sealing device drilling cross body lower part is equipped with second sealing device, first sealing device passes through the jackscrew assembly to be fixed on the drilling cross body, first sealing device is including being located this internal dabber hanger body of drilling cross be equipped with first sealed position and the sealed position of second on the dabber hanger body, first sealed position adopts first sealing washer sealed, the sealed position of second adopts upper padding, well pad, the lower bolster that superposes in proper order and fixes on dabber hanger body through and the cap.
Furthermore, the jackscrew assembly is at least provided, and is symmetrically arranged on two sides of the drilling four-way body to fix the hanger body.
Furthermore, the second sealing device comprises a second sealing ring, and the second sealing ring is fixed on the drilling four-way body through an injection molding valve.
Further, the second sealing ring is a BT sealing ring.
Further, the first sealing ring is an O-shaped sealing ring.
Furthermore, bosses are arranged on the upper pad and the lower pad, and grooves corresponding to the bosses are formed in the two sides of the middle pad.
Furthermore, outlets are arranged on two sides of the drilling four-way body and connected with connecting flanges.
Compared with the prior art, the utility model provides a drilling and production integrated composite multifunctional drilling four-way device, the first sealing ring is arranged in a ring groove at the upper part of the mandrel hanger body, the upper pad is arranged on a boss at the upper part of the mandrel hanger body, and a middle pad and a lower pad are sequentially arranged on the upper pad and are pressed tightly through a combining cap; the sealing effect is good, and the drilling and production effect is improved. A BT sealing ring is arranged at a side outlet at the lower part of the drilling four-way body, and an injection valve is designed for auxiliary sealing, so that secondary sealing of a lower-layer sleeve can be realized. Compared with the traditional integral drilling four-way pipe, the novel drilling four-way pipe has the advantages of saving materials, reducing cost, being convenient to disassemble and the like.
