Abstract
The utility model relates to an irregular drilling tool inner chamber measuring instrument. Its technical scheme is: including umbrella stick, sliding sleeve, connecting rod, spoke, spacer pin and umbrella head, the umbrella stick on be equipped with the scale, and the one end of sliding sleeve passes through spacer pin and umbrella stick fixed connection, the other end of sliding sleeve passes through the one end of connecting rod swing joint spoke, other end swing joint to the umbrella head of spoke, and the spoke is realized the expansion or is closed under the thrust of connecting rod. The beneficial effects are that: use this measuring instrument can measured depth drilling tool and instrument inner chamber internal diameter, construction operation accuracys such as ash, well cementation be annotated in great improvement, have solved the problem that present inside caliper and slide caliper can not solve. The novel simple structure of this measuring instrument, easily processing, construction convenience, improvement construction progress and efficiency that can be in a big way, the effect is pretty good, uses extensively.
Description
Technical field
The utility model relates to a kind of workover rig service to oil well survey instrument, particularly one irregular drilling tool inner chamber surveying instrument.
Background technology
In workover rig service to oil well process, usually run into the construction technology of shutoff, well cementation, the drilling tool structure used and wall thickness uniform internal diameter size indefinite, and the interior card of routine and vernier caliper enough can only measure the reinforcement of drilling tool and the internal diameter of collar segments, the internal diameter size for the body part of the degree of depth is often too far behind to catch up.If we calculate replacement amount at data conveniently, affect less in shallow well construction, but in deep-well often mutually far short of what is expected a lot, stay a lot of or overdisplacing of plug thus bring difficulty to lower step construction, increasing construction workload, have impact on construction speed.Such as when 1537 well shutoff, this well well depth 3650m, for shut-in well section: 3437-3447m, sand string Φ 140 × Φ 118.62mm, well control fluid is relative density 1.45g/cm
3mud, takes shutoff mode to clamp-on method for staying plug.Running string is as follows: Φ 73 drilling rod (3347m)+Φ 73(100m) and nib; Preparation relative density 1.75 mud 1.2m
3, for staying red dog to 3347m, drilling rod internal diameter is uncertain, can have two types (9.19,10.4mm) with reference to wall thickness, and this exists two types (54.62,52.2mm), and replacement amount difference is at ± 0.67m
3, the possibility of having sprayed in trip-out process will be caused like this, cause inconvenience to construction, pollute environment simultaneously.In addition, if in well cementing process, bottom is Φ 95 sleeve pipe, internal diameter is Φ 82mm, hanger plug in particular cases can not be adopted to replace, and (this situation is a lot, particularly at the sidetracked hole of clay-free drilling fluid construction, substantially be not always the case), will cause like this and stay nearly 127m ash plug or overdisplacing more, cause bore plug too much or cementing quality defective, all these cause huge loss all can to the construction of whole project, even cause scrapping of well, therefore wish a kind of novel measuring instrument of design, meet the needs problem of site operation.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of irregular drilling tool inner chamber surveying instrument, solves on-the-spot construction needs cleverly, in sidetracking process, the calculating of replacement amount provides reliable foundation.
Its technical scheme is: comprise umbrella handle, sliding sleeve, connecting rod, spoke, spacer pin and umbrella head, described umbrella handle is provided with scale, and one end of sliding sleeve is fixedly connected with umbrella handle by spacer pin, the other end of sliding sleeve is flexibly connected one end of spoke by connecting rod, the other end of spoke is movably attached to umbrella head, and spoke realizes launching or closing under the thrust of connecting rod.
Above-mentioned umbrella handle sets up extension rod.
The beneficial effects of the utility model are: use this surveying instrument can to fathom drilling tool and instrument inner chamber internal diameter, improve the construction operation accuracys such as note ash, well cementation greatly, solve the problem that current inside caliper and vernier caliper can not solve.This surveying instrument new structure is simple, is easy to processing, easy construction, can raising construction speed in a big way and efficiency, and effect is pretty good, is widely used.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: umbrella handle 1, sliding sleeve 2, connecting rod 3, spoke 4, spacer pin 5 and umbrella head 6.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises umbrella handle 1, sliding sleeve 2, connecting rod 3, spoke 4, spacer pin 5 and umbrella head 6, described umbrella handle 1 is provided with scale, and one end of sliding sleeve 2 is fixedly connected with umbrella handle 1 by spacer pin 5, the other end of sliding sleeve 2 is flexibly connected one end of spoke 4 by connecting rod 3, the other end of spoke 4 is movably attached to umbrella head 6, and spoke 4 realizes launching or closing under the thrust of connecting rod 3.
Wherein, umbrella handle 1 sets up extension rod, and by lengthen sliding sleeve with the use of, be used for measuring darker inner chamber internal diameter.
During use, the utility model is shunk the drilling tool put into and need to measure and instrument inner chamber, then slowly sliding sleeve 2 is promoted, the connecting rod 3 be connected with sliding sleeve 2 symmetry slowly promotes spoke 4 under the thrust of sliding sleeve, spoke freely opens under connecting rod thrust, now by the scale of umbrella handle 1 top, mark can be read easily and come.Wait to shrink sliding sleeve, extract the utility model out, promote sliding sleeve to scale when measuring, locking spacer pin 5, dehisces with vernier caliper measurement spoke, thus very easily measures the inner chamber internal diameter (also can mark corresponding size by graduation calibrating principle) of drilling tool and instrument.Remarks: if measure darker inner chamber internal diameter, the length that can lengthen sliding sleeve and umbrella handle just can easily realize.
The above is only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may utilize the technical scheme of above-mentioned elaboration to the utility model correct or are revised as equivalent technical scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
