Description
Technical field
The utility model relates to the oil field to the test of fracturing propping agents API guide instrument technical field.
Background technology
Frac job is one of Main Means that in field produces, volume increase is transformed to LOW PERMEABILITY RESERVOIR.The effect of increasing production of frac job and the flow conductivity of supporting crack are closely related, and flow conductivity depends on the width of crack and the permeability of crack closure rear support agent.Therefore, only have the propping agent to separate sources to carry out preferably, perhaps before frac job to optimization of the proppants and quality control, optimize the propping agent of best flow conductivity, the job design of guarantee the best.
The flow conductivity laboratory experiment data of fracturing propping agents are propping agent prior appraisals, the important evidence of Optimized fracturing design input parameter, the linear flow propping agent short-term flow conductivity proving installation evaluation of recommending in API RP 61 adopts distilled water to test, and can not accurately reflect actual conditions.
Summary of the invention
The utility model purpose is that the evaluation of the conventional API propping agent of a kind of solution of design flow conductivity adopts distilled water to test, the problem that can not accurately reflect actual flow conductivity can quantize to reflect that different fracturing fluid systems are to the guide instrument that can positive and negatively drive of the extent of injury of propping agent flow conductivity simultaneously.
The utility model comprises that one is used for filling of the fracturing fluid lp piston, lp piston and one group of guide instrument that is used for the dress treating fluid; Describedly be connected to described guide instrument inlet be used to filling of the fracturing fluid lp piston by the first liquid feed valve, described lp piston for the dress treating fluid is connected to described guide instrument inlet by the second liquid feed valve; Connect on the liquid outlet of diversion chamber and just driving outlet valve, at the described outlet valve front end that just driving by the anti-entrance transfer valve front end of operation valve tieback to the inlet that is connected in diversion chamber that drive; Connect the anti-outlet valve that drives by described guide instrument inlet.Diversion chamber at described guide instrument connects respectively the first pressure tap and the second pressure tap; The first pressure tap is connected with the height pressure side of pressure transducer respectively by the first switch valve, second switch valve, and the second pressure tap is connected with the high low side of pressure transducer respectively by the 4th switch valve, the 3rd switch valve; Described pressure transducer one end connects calibrating device, and an end connects ventilating opening.
By controlling the open and close of some valves, the utility model can be simulated the guide instrument of fracturing liquid injury, adopt distilled water to test to solve conventional API propping agent flow conductivity evaluation, the problem that can not accurately reflect actual flow conductivity can quantize to reflect that different fracturing fluid systems are to the extent of injury of propping agent flow conductivity simultaneously.
