specific Embodiment 1

[0029] Such as Figure 1 to Figure 2 As shown, the work platform 800 includes a support cylinder 100 and a standing platform 200 vertically fixed on the support cylinder 100. The support cylinder 100 is set on the outside of the blowout preventer and fixed when in use. The standing platform 200 can be used by the operator to stand. After the operator stands on the standing platform 200, it is convenient to put in and take out the test tool string.

[0030] Specifically, as figure 1 As shown, the support cylinder 100 includes a left semi-annular body 11 and a right semi-annular body 12. Both the left semi-annular body 11 and the right semi-annular body 12 are arc-shaped semi-annular sleeves, and both extend in the axial direction of the support cylinder 100 to a certain extent. The length of the nozzle can be matched and looped around the outside of the blowout preventer during use. Wherein, one end of the left semi-annular body 11 and the right semi-annular body 12 is hinged...

specific Embodiment 2

[0042] Such as image 3 As shown, in Embodiment 1, the locking structure is composed of a locking rod, a nut and a locking plate. In fact, the function of the locking structure is to lock after the two half-rings are combined. Based on this effect, in this embodiment, the locking structure is formed in the following manner, the locking structure includes a left locking plate 107 and a right locking plate 108, and the left locking plate 107 is fixed on the left half ring body 101 and the left foot plate 103 at the same time , the right lock plate 108 is fixed on the right half ring body 102 and the right foot plate 104 simultaneously. Perforations are respectively opened on the left lock plate 107 and the right lock plate 108 . The locking structure also includes a screw rod 105 passing through the two lock plates, and a left nut 106 and a right nut 109 matched with the two screw rods 105 , and the two nuts can cooperate to clamp the left lock plate 107 and the right lock pla...

specific Embodiment 3

[0045] The difference from Embodiment 2 is that in this embodiment, the screw rod in Embodiment 2 is changed to a bolt fixed on one of the locking plates.

Abstract

The invention relates to an operation platform for oil and gas well testing. The operation platform for oil and gas well testing comprises a supporting cylinder, a locking structure and a standing platform, wherein the supporting cylinder is used for being arranged outside a blowout prevention pipe in a sleeving mode and provided with an anti-falling structure capable of being installed in an anti-falling mode relative to the blowout prevention pipe, and the supporting cylinder comprises a left half ring body and a right half ring body which can be horizontally opened and closed; the locking structure locks the left half ring body and the right half ring body and keeps the left half ring body and the right half ring body in an oppositely-closed state after the left half ring body and the right half ring body are oppositely closed; the standing platform is fixed to the supporting cylinder and used for allowing an operator to stand; and the standing platform comprises a left foot plate and a right foot plate which are arranged in a split mode, the left foot plate is fixedly arranged on the left half ring body, and the right foot plate is fixedly arranged on the right half ring body. The collision acting force of each half ring body on the blowout prevention pipe is small, and the two half ring bodies are not prone to being damaged; and due to the fact that the acting force borne by each foot plate is small, the joints between the foot plates and the corresponding half ring bodies are not prone to being torn, the bending degree of the foot plates relative to the half ring bodies is also decreased after the foot plates are used for a long time, and horizontal placement of the foot plates is guaranteed as much as possible.

Description

technical field [0001] The invention relates to an operation platform for oil and gas well testing. Background technique [0002] At present, in oil drilling in-well testing and other processes, it is often necessary to carry out various process operations at the wellhead, mainly testing. Since the wellhead Christmas tree is generally equipped with a relatively high blowout pipe, it is necessary to arrange an operation platform at the wellhead for supplying The operator stands, so that the test tool string is put into the blowout preventer from the upper port of the lubricator pipe, and the test tool string is taken out. [0003] To this end, the Chinese utility model patent with the authorized announcement number CN201896597U provides a simple platform for quick installation of oil and water well blowout pipes, which specifically includes two half-rings that can be opened and closed relatively, and one end of the two half-rings is hingedly assembled together, the other end...
