Technical field
The utility model relates to property of drilling fluid field of measuring technique, particularly a kind of measurement mechanism of appraisal drilling liquid mud cake kinetic friction coefficient.
Background technology
Along with the development of oil drilling technology, extended reach well, horizontal well get more and more, also more and more higher to the requirement of drilling fluid lubricating performance, and the lubricity of drilling fluid plays vital effect to safe construction.
At present domestic and international for drilling fluid mud cake lubricity or Study on Friction Coefficient less, rarely have article to report some new instruments evaluating mud cake lubricities or new method.The instrument of laboratory evaluation mud cake greasy property or friction factor has slide block type filter cake stuck factor analyzer, this instrumentation is simple, but also come with some shortcomings part: the friction factor measured by (1) is the friction factor that slide block starts maximum static friction force generation when gliding, can not actual response dynamic friction coefficient, maximum static friction force is larger than kinetic force of friction; (2) owing to starting slide plate corner when gliding with eye-observation slide block, some lags behind real reading unavoidably, causes bigger error.Therefore, be necessary to develop the measurement mechanism that a kind of measuring accuracy is high, can evaluate mud cake dynamic friction coefficient.
Utility model content
The purpose of this utility model is to provide a kind of drilling fluid mud cake dynamic friction coefficient measuring device, and this device is simple to operate, measurement data is accurate, can the dynamic friction coefficient size of accurate response drilling fluid mud cake.
In order to solve the problem, the technical solution of the utility model is:
Drilling fluid mud cake dynamic friction coefficient measuring device, the base plate of L bracket 1 is provided with levelling bolt 8, at the vertical angle place articulate support plate 3 of L bracket, the other end hinge slide plate 2 of movable supporting board 3, between the base plate that slide plate 2 tilts to be overlapped on L bracket 1 and riser, upper mounted plate 4 and bottom plate 5 is vertically fixed with at slide plate 2 ramp, spacing between upper bottom plate is identical with tested drilling fluid mud cake diameter, independently plectane slide block 11 is set between upper mounted plate 4 and bottom plate 5, the diameter of plectane slide block 11 is much smaller than the diameter of tested drilling fluid mud cake, the time set of plectane slide block 11 coasting time is also provided with between upper mounted plate 4 and bottom plate 5.
Such scheme also comprises:
Described time set arranges conductive contact respectively on upper mounted plate 4 and bottom plate 5 opposite face, and conductive contact is connected with timer 7 by wire 6, and upper mounted plate 4 and bottom plate 5 are set to electric conductor and are connected with timer 7 respectively simultaneously.
Described time set arranges conductive contact respectively on upper mounted plate 4 and bottom plate 5 opposite face, and conductive contact is connected with timer 7 by wire 6, and plectane slide block 11 is set to electric conductor and is connected with timer 7 respectively simultaneously.
At L bracket 1 angle set amount hornwork 9, protractor 9 and movable supporting board 3 are connected by tightening screw 10; The base plate of L bracket 1 is provided with level meter, and described level meter is circle spirit bubble or straight surveyor's staff.
Compared with prior art, the utility model is simple to operation, utilize mechanics principle to calculate the kinetic friction coefficient of mud cake, and can arbitrarily adjust slide plate inclination angle, repeat experiment, automatic data collection, measurement result is more accurate, and the utility model can be widely used in the department such as laboratory in one's power of situ of drilling well, Research Center.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in composition graphs 1, the drilling fluid mud cake dynamic friction coefficient measuring device of the utility model embodiment forms primarily of support 1, slide plate 2, movable supporting board 3, upper mounted plate 4, bottom plate 5, connecting line 6, timer 7, levelling bolt 8, protractor 9, tightening screw 10 and plectane slide block Fig. 2.
Its medium-height trestle 1 is L shape metal support, and bottom is provided with levelling bolt 8 and circle spirit bubble, is used for regulating the level of whole device; Movable supporting board 3 one end is connected with the stationary shaft on slide plate 2, and one end is connected with the axis of L bracket 1, and can rotate about the axis, and is screwed by tightening screw 10 after determining angle, thus controls the inclination angle size of slide plate 2; Upper mounted plate 4 and bottom plate 5 are installed on slide plate, mainly play fixing mud cake, and the distance between upper bottom plate are fixing, equal with formation mud cake diameter; Timer 7 is connected with bottom plate 5 with upper mounted plate 4 respectively by two connecting lines 6, and tie point is contact contact, and contact contact is contact induction self-clocking; Plectane slide block is circular flat panel metal block, electroplating surface polishing.When plectane slide block separates with the contact contact of upper mounted plate 4, timer 7 starts timing, and when plectane slide block starts the contact contact encountering bottom plate 5, timer 7 stops timing.
Utilize the measuring process of said apparatus:
First adjust levelling bolt, make the bubble in circle spirit bubble be in center; Adjusting movable supporting board again makes slide plate be in a fixing inclination alpha, and the mud cake produced by filtration device is fixed on slide plate, and two ends are fixed by upper bottom plate; Distance between upper bottom plate is L; Be m by known quality again, diameter is that the plectane slide block of d is placed on mud cake upper end, and contact contact with upper mounted plate and contact; Now unclamping hand makes slide block start to glide under the effect of partical gravity, and simultaneously timer starts timing, and when slide block drops down onto bottom plate contact contact, timer stops timing, now records timer periods t; Last according to L=a*t
2/ 2, and G*sin α-F=m*a, calculate friction force F, then according to K
f=F/ (G*cos α) calculates the kinetic friction coefficient K of mud cake
f.
