Abstract

The invention relates to a pluralistic oil production wellhead device. The pluralistic oil production wellhead device is characterized in that a pluralistic device is equipped at the bottom of a production tree; a housing is arranged in the integrated pluralistic device, a flange is arranged at the upper part of the housing, a double ram type preventer is equipped at the middle and upper part of the housing, side outlet channel pipelines are respectively equipped on two side outlet channel interfaces at the middle and lower part of the housing, and a sleeve internal thread is arranged at the lower part of the housing for connecting with a sleeve; and multiple groups of integrated holes for mounting jackscrew components are formed in the outer circle of the flange at the upper part of the housing, an inner taper hole of the flange at the upper part is in close fit with a sealing part at the upper part of a mandrel type oil pipe hanger, a sealing position at the lower part of the mandrel type oil pipe hanger is processed between the double ram type preventer at the middle and upper part and the side outlet channel interfaces at the middle and lower part, and the remaining holes are of through holes. The pluralistic oil production wellhead device disclosed by the invention meets the pluralistic requirements of integrating oil test and production, operation, fracturing and well repair into a whole, has the advantages of simple structure, convenience in use and capabilities of saving operation time and reducing operation cost, and further has significance for pluralism of oil test and production, operation, fracturing and well repair and production optimization.

Description

technical field [0001] The invention relates to a diversified oil production wellhead device integrating test production, operation, fracturing and workover, and belongs to the field of petroleum production equipment. Background technique [0002] Oil production wellhead device is an important equipment for oil production after drilling and completion. At present, there are many kinds of oil production wellhead devices used on site, with different structures, single purpose and incomplete function. If other procedures are required, the suitable one must be replaced. Equipment can only be completed, which not only wastes time, but also increases costs, and does not meet the needs of market development. Contents of the invention [0003] The purpose of the present invention is to provide a diversified oil production wellhead device integrating test production, operation, fracturing and workover, so as to achieve other program operations without replacing suitable equipment, ...
