Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is a kind of human-cutting high slope interleaving agent evaluation method flow chart according to embodiment of the present invention.As shown in Figure 1, the human-cutting high slope interleaving agent evaluation method that embodiment of the present invention provides, comprising: S101, determines the physical characteristic of described interleaving agent, and this physical characteristic comprises and of the fracturing fluid compatibility; S102, when determining described interleaving agent and described of the fracturing fluid compatibility is good, detects the floating/subsidence velocity of described interleaving agent in described fracturing fluid; S103, determines that intensity is blocked on the stratum of described interleaving agent; And S104, export evaluation result.Pass through technique scheme, can comprehensively carry out physical characteristic evaluation, floating/subsidence velocity evaluation to interleaving agent to be evaluated and block intensity evaluation, thus effective evaluation is carried out to interleaving agent, and evaluation method considers the applied environment (temperature and pressure) on stratum, and the result therefore evaluated can directly apply to scene.
In embodiments, can for the base fluid by melon glue and water configuration according to the fracturing fluid used in evaluation method of the present invention.Such as, melon matrix liquid concentration can be following one at least: 0.1%, 0.15%, 0.2%, 0.25% and 0.3%.By detecting the floating/subsidence velocity of interleaving agent to be measured in the melon matrix liquid of variable concentrations, combination property and the applicability of interleaving agent can be checked.
In evaluation procedure is carried out, after certain density interleaving agent adds base fluid, the most particle of interleaving agent with fast speed deposition or can float up to container bottom or liquid level.And may there are differences due to the particle diameter of often kind of interleaving agent, cause sinking between the particle of single interleaving agent or ascent rate phase missionary society very large.And likely there will be to unite between particle sinking or rising phenomenon, thus accelerate sinking or the ascent rate of interleaving agent.These situations bring difficulty to the measurement of interleaving agent float-and-sink rate.Therefore, in a preferred embodiment, the floating/subsidence velocity of interleaving agent can be average speed, and wherein, the time of the segment distance that can be floated/sink in described fracturing fluid by the particle recording described interleaving agent calculates this average speed.By recording the total time spent by most of particle moving certain distance, ask for average speed, though this average speed accurately can not react sedimentation or the floating rule of interleaving agent, but can as a reference, can from sinking or the ascent rate macroscopically characterizing different interleaving agent.
Below by a concrete embodiment, principle of the present invention is further illustrated.
In embodiments, utilize human-cutting high slope interleaving agent evaluation method provided by the invention to evaluate, wherein, in floating agent following four kinds of interleaving agents: S1 is the floating agent of certain field produces, S2 is the hollow glass micropearl that certain company produces; In sinking agent: X1 is 80/100 order haydite, X2 is 100/120 order haydite.
