It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
Fig. 1 is please referred to, is a kind of closure matching relationship of determining elastic granule and formation pore throat provided by the disclosure The flow diagram of method.It should be noted that determination elastic granule described in the disclosure matches pass with the closure of formation pore throat The method of system is not limitation with Fig. 1 and specific order as described below, it should be understood that in other embodiments, the disclosure The sequence of the method part step of the closure matching relationship of the determination elastic granule and formation pore throat can be according to reality Border needs to be exchanged with each other or part steps therein also can be omitted or delete.Process shown in FIG. 1 will be carried out below detailed It is thin to illustrate.
Step 101, the closure pressure for carrying out formation shut-off is obtained.
Since during carrying out formation shut-off, the stratum of different geographical environments has different pressure, and in difference Under pressure, in order to reach ideal plugging effect, the particle size of sealing agent needs and the size of formation pore throat matches, because This, is currently blocking the sealing agent to match under pressure with formation pore throat, available carry out formation shut-off for the ease of determining Closure pressure.
Blocking pressure is to carry out the compression pressure at formation shut-off.
Wherein it is possible to which the closure pressure for carrying out formation shut-off is determined in advance.For example, reality can be passed through by related technical personnel Border detection or previous detection experience, determine the closure pressure, thus can receive the number that the related technical personnel are submitted Value is used as the closure pressure.
Sealing agent is the material for carrying out formation shut-off, and the sealing agent may include rigid particles and elastic granule.
For example, rigid particles may include the material particles such as sandstone, elastic granule may include hydroexpanding body, pre-pay it is conjuncted, The material particles such as nanosphere.
Step 102, based on pressure is blocked, determine that elastic granule is under the closure pressure used by carrying out formation shut-off Elastic deformation coefficient.
Since elastic deformation may occur for elastic granule, under different closure pressure, the ruler of the elastic granule It is very little also to change, therefore, in order to improve determine carry out formation shut-off when and formation pore throat elastic granule accuracy, can To determine elastic deformation coefficient of the elastic granule under current closure pressure used by carrying out formation shut-off.
Elastic deformation coefficient is for illustrating that elastically-deformable degree occurs for elastic granule.
The elastic deformation coefficient of a variety of elastic granules at various pressures can be determined in advance, and each elastic granule is distinguished In the corresponding storage of the elastic deformation coefficient of different pressures, so as to according to identified elastic granule and block pressure, really Fixed elastic deformation coefficient of the elastic granule under the closure pressure.It certainly, in practical applications, can also be otherwise Obtain elastic deformation coefficient of the elastic granule under the closure pressure, for example, can by identified elastic granule and It blocks pressure and shows user, to receive user for the elastic granule and the numerical value of closure pressure submission as the elasticity Deformation coefficient.
Step 103, it based on the closure matching factor of elastic deformation coefficient, preset rigid particles and formation pore throat, determines When carrying out formation shut-off using elastic granule, the closure matching factor of the elastic granule and formation pore throat.
Since rigid particles will not deformation occurs, alternatively, the deformation occurred is for carrying out this applied field of formation shut-off It can be ignored for scape, therefore for any rigid particles, the closure matching factor of the rigid particles and formation pore throat is all It is consistent.In addition, when elastic granule be compressed into can not continue deformation (such as completely compression, alternatively, in a certain closure pressure Down abundant deformation and can not continue that deformation occurs) when, can also regard as rigid particles, at this point, for same formation pore throat and Speech, the matching factor of the elastic granule and formation pore throat can be consistent with the matching factor of formation pore throat with rigid particles, because This, can be based on elastic deformation coefficient, the i.e. closure of the elastic granule degree that deformation occurs and rigid particles and formation pore throat Matching factor determines the closure matching factor of elastic granule and formation pore throat.
The closure matching factor of rigid particles and formation pore throat can be by being determined in advance to obtain, such as can be in advance by phase Technical staff is closed by carrying out closure experiment, the closure matching factor of rigid particles and formation pore throat is determined, so as to receive The numerical value that related technical personnel submit is using the closure matching factor as rigid particles and formation pore throat.
Blocking matching factor may include the particle diameter of sealing agent and the ratio of formation pore throat diameter.
Can will be aforementioned in be compressed into and can not continue the elastic granule of deformation and regard rigid particles as, so that it is determined that this is just Property particle and formation pore throat closure matching factor, further according to elastic deformation coefficient, (i.e. elastically-deformable journey occurs for elastic granule Degree), identified closure matching factor is modified, thus when obtaining carrying out formation shut-off using the elastic granule, the bullet The closure matching factor of property particle and formation pore throat.
In the embodiments of the present disclosure, for carrying out elastic granule used by formation shut-off, available progress stratum envelope Stifled starve blocks pressure, and elastic deformation coefficient of the determination elastic granule under the closure pressure, when elastic granule is compressed into It can also regard as when can not continue deformation as rigid particles, it is thus possible to be based on the elastic deformation coefficient, preset rigid particles With the closure matching factor of formation pore throat, when determining using elastic granule progress formation shut-off, the elastic granule and formation pore throat Closure matching factor, and then can be avoided by way of blocking experiment and determine the envelopes of various elastic granules and formation pore throat Stifled matching factor, improves efficiency, saves cost.
It referring to figure 2., is the closure matching relationship of a kind of determining elastic granule provided by the disclosure and formation pore throat The flow diagram of method.It should be noted that determination elastic granule described in the disclosure matches pass with the closure of formation pore throat The method of system is not limitation with Fig. 2 and specific order as described below, it should be understood that in other embodiments, the disclosure The sequence of the method part step of the closure matching relationship of the determination elastic granule and formation pore throat can be according to reality Border needs to be exchanged with each other or part steps therein also can be omitted or delete.Process shown in Fig. 2 will be carried out below detailed It is thin to illustrate.
Step 201, the closure pressure for carrying out formation shut-off is obtained.
Wherein, the mode for carrying out the closure pressure of formation shut-off is obtained, the correlation that may refer in abovementioned steps 101 is retouched It states, no longer repeats one by one herein.
Step 202, elastic granule used by carrying out formation shut-off is determined.
Since the type of elastic granule is more, and different elastic granules also have different attributes, such as different elasticity Deng therefore, for the ease of the subsequent closure matching factor for accurately determining the elastic granule and formation pore throat, with can determining progress Elastic granule used by layer blocks.
Wherein it is possible to receive the elastic granule of user's submission as elastic granule used by progress formation shut-off.
