Injection and production integrated wellhead device

Abstract

The invention discloses an injection-production integrated wellhead device, which comprises a tubing head cross, a heat insulation pipe, a first gate valve, a lower flange, a cross flange, a tubing short, a coupling, a second gate valve and a clamp head; The oil pipe head cross is provided with a heat insulation pipe; the left and right ends of the oil pipe head cross are provided with a first gate valve; the lower end of the oil pipe head cross is provided with a lower flange; The first passage, the second passage and two third passages communicate with each other; the upper end of the four-way connection of the oil pipe head is connected with the second passage in the four-way flange; the two third passages are respectively connected with a first gate valve; The first channel is provided with an oil pipe short connection; the oil pipe short connection is connected with the second gate valve through a coupling; the upper end of the second gate valve is connected with a clamp head, and the injection-production integrated wellhead device of the present invention has a simple structure , easy to operate, labor-saving, low production cost, the gas injection device and the oil recovery device can work in mutual circulation, which improves the production efficiency, reduces the number of operations, and meets the actual operation needs.

Description

technical field [0001] The invention belongs to the technical field of oilfield exploitation, in particular to an injection-production integrated wellhead device. Background technique [0002] In oilfield exploitation, two types of equipment, gas injection device and oil production device, are often needed to complete corresponding operations. However, after a long period of use, it was found that such a production mode has some disadvantages. Firstly, the production cost of the two types of equipment is very high. Secondly, after the gas injection is completed, the corresponding oil production device needs to be replaced for oil production. This not only produces The efficiency is low and the number of operations is high at the same time, which brings inconvenience to the actual operation. Therefore, there is an urgent need for a device that can circulate between the gas injection device and the oil production device to perform operations, thereby improving work efficiency ...

However, after a long period of use, it was found that such a production mode has some disadvantages. Firstly, the production cost of the two types of equipment is very high. Secondly, after the gas injection is completed, the corresponding oil production device needs to be replaced for oil production. This not only produces The efficiency is low and the number of operations is high at the same time, which brings inconvenience to the actual operation. Therefore, there is an urgent need for a device that can circulate between the gas injection device and the oil production device to improve work efficiency and save time and effort.
