Abstract
The utility model discloses a safety protection device of a logging while drilling apparatus, designed to solve the problem of the operator safety when the logging while drilling apparatus is assembled and connected in the well mouth, the safety protection device comprises a clamping disk and a stopping disk which are connected by a supporting rod; when the safety protection device is used, the assembling operation is performed in a supporting space of the supporting rod, so that the damage caused by parameter sub drop when the logging while drilling apparatus is assembled and connected in the well mouth can be avoided effectively; the quick assembly of the parameter subs can be achieved under the condition that the field operation environment is complex, and the safety coefficient is low. The safety protection device has simple structure and low cost, can eliminate the potential safety hazard of the logging while drilling field operation at long period and effectively solve the safety protection problem of the field operator.
Description
Technical field
The utility model relates to a kind of well logging during instrument safety guard, belongs to logger mechanical protection equipment technical field.
Background technology
Novel well logging during system owing to the parameter pipe nipple that articulates is that the instrumented drilling rod of centre bore is many and quality each parameter pipe nipple is very big again, all is that well head is assembled on the spot at the scene generally speaking.Because well head operation more complicated; And there are a lot of Unpredictability problems; Careless slightly operating personnel's personal safety will receive the threat of upper suspension parameter pipe nipple, and this just requires well logging during operation to be equipped with to have the high safety convenience instrument of security reliability.
Summary of the invention
The purpose of the utility model is to provide a kind of well logging during instrument safety guard, and it can solve well logging during instrument operating personnel's when well head connects safety problem effectively.
The concrete technology contents of the utility model is following:
This well logging during instrument safety guard is made up of chuck, pole and block plate, and chuck is made up of axial ring and its annular radial end face, and annular end face is provided with the pole that is uniformly distributed with, and the pole top connects the ring-type block plate, and block plate and chuck are provided with the coordination longitudinal cut.
The advantage of the utility model is:
The potential safety hazard of well logging during execute-in-place since this well logging during instrument safety guard has been eliminated for a long time, the fast quick-acting of each parameter pipe nipple of realization under the situation that operating environment is complicated at the scene, safety factor is low.This apparatus structure is simple, with low cost, fast and reliable, can effectively avoid the well logging during instrument when well head docks, to fall the personnel's injury that causes, solution site operation personnel's safeguard protection problem because of the parameter pipe nipple.
Description of drawings
Accompanying drawing 1,2 is well logging during instrument safety guard structural representation.
Accompanying drawing 3 is well logging during instrument safety guard work sketch map.
The specific embodiment
Embodiment:
Embodiment with reference to 1 to 3 pair of the utility model of accompanying drawing further specifies:
This well logging during instrument safety guard is made up of chuck 1, pole 2 and block plate 3; Chuck 1 is made up of axial circular ring and its radially circular annular end face; Circular annular end face is provided with three poles that are uniformly distributed with 2; Pole 2 tops connect circular ring-type block plate 3, and block plate 3 is provided with the coordination longitudinal cut with chuck 1.
The utility model concrete operation method is following:
Block mentioning well head 5 on the parameter pipe nipple 4 earlier, the derrick hook block is sling another parameter pipe nipple 8, transfers to apart from about well head 5 drilling rod 300mm; Operating personnel are installed in safety guard on the parameter pipe nipple 4 that well head blocked, and from the parameter pipe nipple of slinging 8, pull out communication attachment plug 7 downwards, clean the interface of upper and lower parameter pipe nipple 4 and 8; Remove protective cap; Through the space between the pole 2 communication gang socket 6 is inserted in communication attachment plug 7 and realize that safety connects, then with carrying disengagement parameters pipe nipple 4 on the safety guard; Longitudinal cut through chuck 1 breaks away from communications connectors; Unload safety guard, with hydraulic tongs two parameter pipe nipples are tightened then, accomplish the connection procedure of whole instrument.
Three passive pole 2 diameter 25mm, length 200mm through strength accounting, can bear 2.5 tons weight (used usually parameter pipe nipple drilling rod is the heaviest to be 1.5 tons).Chuck 1, pole 2 and block plate 3 are assembled together through welding.
