Description
Technical field
The present invention relates to liquid barrier property testing apparatus and the method thereof of propping agent, being specifically related to a kind of tester for detecting propping agent time of penetration and method of testing thereof.
Background technology
In the performance history of Oil/gas Well, due to the continuous decline of reservoir pressure, cause edge water propelling and end liter waterborne, in addition the increasing yield and injection operation such as pressure break, acidifying, water filling, cause the oil gas water percentage of producing well to raise, even reach more than 90%, this not only makes production efficiency decline, make oil gas field sewage load sharply increase simultaneously, consume a large amount of human and material resources.The propping agent with selectivity liquid barrier property injects stratum in fracturing process, for supporting crack, improves a kind of material with blocking solution characteristic of fracture flow capacity, obviously can reduce the water rate of Oil/gas Well, improve oil and gas production.Liquid barrier property refers to, propping agent hinders liquid to pass through ability when normal pressure is piled up, can represent that i.e. time of penetration represents with the time hindering Liquid Penetrant to pass through.The test index of the liquid barrier property of Uniform provisions propping agent, instrument, method etc. are not had in the company standard of oil and gas industry standard and the large enterprise such as PetroChina Company Limited., China Petrochemical Industry.

One as the above embodiment of the present invention is out of shape, and described liquid reserve tank adopts transparent material manufacture, and is carved with scale on outer wall, cancels the setting of fluid level gauge.
Based on same inventive concept, the method for testing that the present invention also provides above-mentioned tester to realize, comprises the steps:
S1: propping agent to be measured is inserted in lower customization graduated cylinder 112, and the upper surface of described propping agent to be measured is struck off and filter paper of mating formation, in the process of charging, level sensor on first 109 is imbedded described test propping agent middle distance upper surface 2mm position, described lower first time level sensor 110 is imbedded described test propping agent middle distance lower surface 2mm position, and (distance on described first between level sensor 109 and first time level sensor 110 is the filling thickness of propping agent, in the present embodiment, the filling thickness of propping agent to be measured is 146mm), and respectively level sensor 109 on described first is connected with first processor 104 with described first time level sensor 110, then described upper customization graduated cylinder 103 is customized graduated cylinder 112 for 112 times with lower customization graduated cylinder to be oppositely arranged, and customize on described on the outer wall that connects between graduated cylinder 103 and described lower customization graduated cylinder 112 and be provided with draw-in groove and closure, finally sealed by elastic seal ring, ensure that described upper customization graduated cylinder 103 seals completely with lower customization graduated cylinder 112 junction,
S2: test liquid is continued to inject described upper customization graduated cylinder 103 with 60-80ml/min speed by constant flow pump; Simultaneously, described first processor 104 receives the signal of level sensor 109 on described first, and record level sensor 109 on described first and sense the time of liquid, and stop when on described first, level sensor 109 has sensed liquid injecting test liquid to described dress liquid portion; Now, the liquid height of described 103 li, upper customization graduated cylinder is the blocking solution height of described propping agent to be measured;

S3: under processor for recording, described lower level sensor senses the time of liquid;
S4: described lower level sensor senses that the time of liquid and described upper level sensor sense that the time interval of liquid is time of penetration.
7. method of testing according to claim 6, is characterized in that, in described step S2, by feeding device, liquid is injected described dress liquid portion under the prerequisite not destroying described propping agent upper surface to be measured.
8. method of testing according to claim 7, is characterized in that, in described step S2, liquid is pumped into described measurement mechanism by constant flow pump by described feeding device, and the speed that pumps into of described constant flow pump is 60-80ml/min.
9. the method for testing according to any one of claim 6 or 7, is characterized in that, in described step S1, the upper surface being also included in described propping agent to be measured covers the step of filter paper.
10. the method for testing according to any one of claim 6 or 7, is characterized in that, before described step S1, also comprises and to dry described propping agent to be measured and to be cooled to the step of room temperature.
11. method of testings according to any one of claim 6 or 7, it is characterized in that, repeat step S1 for more than five times to step S4, obtain more than five time of penetration values respectively, give up the individual data point obviously departing from actual value, and the mean value obtaining all the other time of penetration values is as final time of penetration.
