1. Summary Shearometer Kit of drilling fluid measures magnitude of strengthen of grid structure,i.e. static shear force, which caused by attraction and bonding among many clay grains.It is the force that can break grid structure of drilling fluid per unit area. Initial and terminal shear force measured are all significative for drilling and protecting hole. 2. Model: RSK-5 & RSK-20 3. The major technical parameters of the instrument The major technical parameters of the instrument are listed in the following table. ITEM Name Technical parameter Inner diameter: Φ35.56mm1.4 1 Floating pontoon...

Cup of drilling fluid Fluted sunk screw floating pontoon staff gauge rod staff gauge Roundhead screw (2) Working principles Stir measured drilling fluid to symmetric suspension,and then pouring it into cup of drilling fluid.Measuring initial shear force of drilling fluid in one minute by its free subsidence in floating pontoon. Pouring symmetric drilling fluid into the cup again and keeping fluid still 10 minutes. Then,measuring initial shear force of drilling fluid again. 5. The operation of instrument: [1]Fit stand-by appication floating pontoon (3) into the bottom of cup of drilling...

Rigchinci GCCLP maintained and cleaned. Avoid causing deformation of components that can influence accuracy and usage of the instrument. (4)Ensure that staff gauge is vertical to drilling fluid level. (5)Floating pontoon should be kept clean,intact and indeformable. (6)Measured data is accurate only when floating pontoon lightly touch drilling fluid level before it falling down freely. (7) Shearometer parts should be cleaned and dried after use.

This weight is 20 grams. C. Starting with a small gram weight from the weight set, add gram weights until the tube starts to sink into the sample. The tube will stop its downward motion at the point where the shear strength of the gelled sample against the surface of the tube is sufficient to support the applied weight. D. Measure the length of the tube exposed above the sample, (3.5-X in inches). Calculate X if the formula on Fig. 6 is to be used. E. The shear strength in pounds per 100 square feet is obtained from the nomograph (Fig. 6) by utilizing the force, in grams, (20 + gram...

7. The Transportation and Storage of Instrument The transportation and storage of instrument should correspond to the JB/T9329-1999 standard. The product should be stored in the room ventilated. The indoor air cannot contain the impurity which can cause corrosion of parts of instrument. 8. Fault judge and remove (1)FaultA little liquid leaks from the cup of drilling fluid. Cause:Connection screw of the cup of drilling fluid with the bottom of staff gauge rod loosed. Remove:Demount the loosed screw and take out staff gauge rod.Then daub sealing glue on the bottom of rod.Finally,remount and...
