Abstract
The utility model relates to a suspension pressure test device, which comprises a public oil drill 1, a body 2 and a suspended rod hoop head 3, wherein the body is of tube structure which is provided on two ends with box thread, the body upper end is connected with the public oil drill, lower end of the body is connected with suspended rod hoop head, the suspended rod hoop head is of tapered tube structure and is provided with pin thread which coordinates with the body on one end and box thread coordinating with the extracting rod on the other end, the thread outer edge is provided with multi passage communicated with each other, the passage is provided on the outer edge with multi tapered steel ring groove. The suspension pressure test device is capable of meeting the need of pressure test work of the downward extracting rod at any time, which prevents the lockout phenomenon caused by waiting to test the pressure after placing the oil pipe, which increases on-spot construction efficiency and is reasonable in structure, simple in processing, low in cost and convenient in use.
Description
Affiliated technical field:
The utility model relates to a kind of pressure testing device that oil well repairing operation is used that is used for, particularly a kind of suspension type pressure testing device.
Background technology:
At present, when oil well repairing operation is constructed, behind the following intact oil pipe, must carry out pressure testing, could lower sucker rod after pressure testing is qualified.But when practice of construction, the pressure testing car can not be in time after often oil pipe had been played in generation, waited for the phenomenon of pressure testing thereby cause to stop work, and had influenced efficiency of construction.
Summary of the invention:
For overcome played oil pipe in the prior art after the pressure testing car can not be in time, causing stops work waits for pressure testing, influence the deficiency of efficiency of construction, the utility model provides a kind of suspension type pressure testing device that the oil well operation is used that is used for, this device can carry out pressure testing in any time in the lower sucker rod process, and need not after intact oil pipe pressure testing down is qualified, just carry out the lower beam operation, guarantee the continuity of construction to have improved efficiency of construction.
The technical scheme that its technical problem that solves the utility model adopts is: this pressure testing device is made up of public oil head in the ninth of the ten Heavenly Stems, body and hanging stick clip head.Its architectural feature is: body is the tubular structure that two ends are equipped with box thread, and the body upper end is connected with public oil head in the ninth of the ten Heavenly Stems, and the lower end is connected with hanging stick clip head; Hanging stick clip head is the tapered tubular structure, and an end is provided with the male thread that matches with body, and the other end is the box thread that matches with sucker rod, is provided with several fluid courses around the screw thread, and the fluid course outer is provided with trapezoidal steel ring slot.Before the pressure testing operation, be tightened in public affairs oil head in the ninth of the ten Heavenly Stems, hanging stick clip head on the body respectively; Oil pumping pole socket in the well on rod elevator, is linked together the sucker rod in hanging stick clip head lower end and the well and tightens; Pipe elevator is buckled on the body slings rod elevator is fallen down, hanging stick clip head is buckled on the steel ring of wellhead flange top clip head and and tightens with clip with hook; The fluid course of highly pressurised liquid around hose, public oil head in the ninth of the ten Heavenly Stems, body, hanging stick clip head lower end box thread that is pumped by the pressure testing car enters oil pipe, just can carry out the pressure testing operation by rules.
Use this device to avoid waiting for the shut-down phenomenon that pressure testing causes behind time intact oil pipe, thereby improved site operation efficient, and rational in infrastructure, and processing is simple, and is with low cost, safe and convenient to use.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, the utility model is made up of public oil ninth of the ten Heavenly Stems 1, body 2 and hanging stick clip head 3.Wherein, be equipped with the tubular filament discount of pin thread public oil ninth of the ten Heavenly Stems 1 for two ends.Body 2 is equipped with the tubular structure of box thread for two ends, and the upper end of external cylindrical surface is provided with shoulder.Hanging stick clip head 3 outsides are provided with the pin thread that matches with body for the upper end, and the centre is provided with conical surface transition, and the lower end is the bigger face of cylinder of diameter; Inner screw thread is provided with the fluid course that several communicate with the large aperture, upper end on every side for the upper end is that large aperture, lower end are the variable-diameter structure of less tapped bore, and the fluid course outer is provided with trapezoidal steel ring slot.
