Abstract
The utility model provides a kind of protective device of well-logging probe; including probe; probe is installed on rigid protective shell by the cylinder with piston rod; rigid protective shell both ends are connected by torsional spring with the first arc-shaped cover and the second arc-shaped cover respectively; first arc-shaped cover and the second arc-shaped cover are connected by electromagnet, and the piston rod can release well-logging probe when extending out of rigid protective shell.The beneficial effects of the utility model are：During well-logging probe enters well, can effectively protect probe, probe surrounding is closed state, and well-logging probe can obtain effective protection during the well entry process；Simple in structure, processing cost is low, is not in the phenomenon of blocking.
Description
Technical field
The utility model belongs to oil exploration equipment technical field, more particularly to a kind of protective device of well-logging probe.
Background technology
Well-logging probe is the instrument for completing underground logging operation, primarily to the characteristic of bed boundary in drilling well is found out,
Divide geologic section.Well-logging probe is easily damaged when colliding rigid obstruction during entering well, can generally lead to
Cross and install protective device additional on probe and solve the problems, such as this, effectively to protect well-logging probe, but it is existing the problem of be existing
Protective cover is typically all lower ending opening, and the position for causing drill bit the most fragile can not be protected, and in addition debris blocks protection dress
Put also so that probe is difficult to play a role.
The content of the invention
The purpose of this utility model is to provide it is a kind of it is simple in structure, easy to operate, cost is low, easy to utilize
The protective device of well-logging probe.
Probe be installed in by the cylinder with piston rod on rigid protective shell, rigid protective shell one end by the first torsional spring with
First arc-shaped cover connects, and the rigid protective shell other end is connected by the second torsional spring with the second arc-shaped cover, first arc-shaped cover and
Second arc-shaped cover is ferrous metal, and the first arc-shaped cover and the second arc-shaped cover are connected by electromagnet.
Vacuum extractor is additionally provided with rigid protective shell.
The top of the rigid protective shell is fixed with hanging ring.
The protective device of well-logging probe described in the utility model, its advantage are：
(1) it is closed state around probe, well-logging probe can obtain effective protection during the well entry process；
(2) simple in structure, processing cost is low, is not in the phenomenon of blocking.
Brief description of the drawings
Fig. 1 is a kind of folding condition schematic diagram of the protective device of well-logging probe；
Fig. 2 is a kind of closing structure schematic diagram of the protective device of well-logging probe.
Figure label explanation：
Probe 1, piston rod 2, cylinder 3, rigid protective shell 4, the first torsional spring 5, the first arc-shaped cover 6, the second torsional spring 7, second
Arc-shaped cover 8, electromagnet 9, vacuum extractor 10.
Embodiment
To describe technology contents, construction feature, institute's reached purpose and effect of the utility model in detail, reality is hereby enumerated below
Apply example and coordinate attached drawing to be explained in detail.
As shown in Figure 1, 2, a kind of protective device of well-logging probe, including probe 1, probe 1 pass through the cylinder with piston rod 2
3 are installed on rigid protective shell 4, and 4 both ends of rigid protective shell pass through the first torsional spring 5 and the second torsional spring 7 and the first arc-shaped cover 6 respectively
Connected with the second arc-shaped cover 8, the first arc-shaped cover 6 and the second arc-shaped cover 8 are connected by electromagnet 9；The rigid protective shell 4
Top is additionally provided with vacuum extractor 10.
The course of work of the utility model：
The present apparatus is fixed on to the output terminal of well-logging probe, well-logging probe 1 is during well is entered, rigid protective during use
Shell 4 can play a good protective effect, and well-logging probe 1 is damaged when collision free is to rigid encumbrance and provides one smoothly
Transmission environment.
When well-logging probe 1 is under the protection of this protective device, reaches predetermined depth in well, electromagnet 9 is opened, such as Fig. 1
Shown, cylinder 3 starts at this time, and well-logging probe 1 is released rigid protective shell 1 and carries out data acquisition by piston rod 2.
Hanging ring 11 is used as fixing piece, easy to disassemble；The vacuum extractor 10 being additionally provided with rigid protective shell 4 can allow first
6 and second arc-shaped cover 8 of arc-shaped cover combines closer, to prevent debris from pouring in.
In conclusion the only preferred embodiment of the utility model, does not limit the scope of protection of the utility model with this, it is all
The equivalent changes and modifications made according to the utility model patent scope and description, is all what the utility model patent covered
Within the scope of.
