[0027] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 .

[0028] Figure 2 is a flow chart of a method for processing construction parameters according to an embodiment of the present invention, such as Figure 2 As shown, the method comprises the following steps:

[0029] Step S202, obtaining a plurality of construction parameters corresponding to a plurality of time points during the reservoir transformation construction, wherein the plurality of construction parameters are used for performing the reservoir transformation construction.

[0030] In this step, when exploiting oil and gas reservoirs, some reservoirs are relatively dense, and the reservoirs need to be transformed to allow the oil or gas in the formation to flow out. When transforming the reservoir, a wellbore is generally established to the reservoir that needs to be transformed, and then the fluid for transforming the reservoir is injected into the formation through the wellbore. Usually, liquid is first input to cause cracks in the reservoir, and then liquid carrying a support is injected to prevent the cracks from closing, and finally the oil or gas in the reservoir can be discharged smoothly. It should be noted that, in general, the wellbore is filled with liquid in the formation.

[0031] The multiple construction parameters include values ​​of multiple parameters related to reservoir construction at multiple times. The multiple parameters may include the displacement of the input liquid, the density of the input liquid, whether the input liquid carries supports, the density of the supports, etc.

[0032] Step S204, determining the distribution of the fluid in the target wellbore at the target time according to the multiple construction parameters, wherein the multiple times include the target time, and the target wellbore is used to transport the fluid used to transform the reservoir to the reservoir.

[0033] In this step, since the reservoir reconstruction construction requires fluid to be injected into the target wellbore, the fluid in the target wellbore is flowing, so the fluid distribution in the target wellbore will change. Multiple construction parameters can be analyzed in depth to determine which fluids are included in the target wellbore at the target time and the locations of these fluids in the wellbore.

[0034] Step S206, determining a target bottom hole pressure at a target time according to the distribution of the fluid in the target wellbore.

[0035] Through the above steps, the purpose of analyzing the construction parameters to obtain the bottom hole pressure of the wellbore to better guide the reservoir transformation construction is achieved, thereby realizing the technical effect of in-depth analysis of the reservoir transformation construction parameters to determine the bottom hole pressure, and further solving the technical problem of the lack of in-depth data analysis methods for reservoir transformation construction parameters in the prior art.

[0036] As an optional embodiment, the target bottom hole pressure at the target moment is determined according to the distribution of the fluid in the target wellbore, including: respectively determining the mass of the liquid included in the fluid in the target wellbore and the mass of the proppant included in the fluid in the target wellbore; determining a first pressure and a second pressure according to the mass of the liquid and the mass of the proppant, wherein the first pressure is the pressure exerted on the bottom hole of the target wellbore by the gravity of the liquid, and the second pressure is the pressure exerted on the bottom hole of the target wellbore by the gravity of the proppant; determining the pressure loss caused by the frictional resistance exerted by the flow of the fluid in the target wellbore according to the distribution of the fluid in the target wellbore; and determining the target bottom hole pressure according to the first pressure, the second pressure and the pressure loss.

[0037] Optionally, the values ​​of various construction parameters at the current moment can be recorded once at fixed intervals, for example, the values ​​of various construction parameters can be recorded once every second. The pressure on the bottom of the well caused by the weight of the liquid and the proppant can be determined based on the mass of the liquid input into the target wellbore and the mass of the proppant input into the target wellbore. As the fluid flows in the target wellbore, the pressure of the fluid in the target wellbore on the bottom of the well will be partially lost due to the flow. The pressure loss caused by the frictional resistance generated by the fluid flow can also be determined by the distribution of the fluid in the target wellbore, and the target bottom hole pressure of the target wellbore is finally determined.

[0038] As an optional embodiment, the pressure loss caused by the frictional resistance generated by the fluid flow in the target wellbore is determined according to the distribution of the fluid in the target wellbore, including: obtaining the corresponding relationship between the pressure of the flow loss of the standard liquid in the experimental wellbore and the displacement of the standard liquid injected into the experimental wellbore, wherein the models of the experimental wellbore and the target wellbore match; determining the positions of multiple liquids included in the fluid in the target wellbore in the target wellbore according to the distribution of the fluid in the target wellbore; determining the liquid displacement injected into the target wellbore at the target time according to multiple construction parameters; obtaining the friction coefficients of multiple liquids; and determining the pressure loss caused by the frictional resistance generated by the fluid flow in the target wellbore according to the positions of the multiple liquids in the target wellbore, the liquid displacements, the friction coefficients of the multiple liquids and the corresponding relationships.

[0039] Optionally, Figure 3 It is a schematic diagram of different fluid compositions in an oil pipe combination and a wellbore provided according to an optional embodiment of the present invention. The diameter of the target wellbore is not the same everywhere, and the friction loss caused by different fluids flowing through wellbores with different diameters is different, so the distribution of the fluid in the target wellbore is required to confirm the positions of different fluids in the wellbore, and the fluids at different diameters in the wellbore are divided into blocks for calculation. In each block, there is only a fluid of a single density flowing through a wellbore of a single diameter, and the pressure loss caused by the frictional resistance generated by the fluid in the target wellbore in each block is calculated separately.

[0040] When calculating the pressure loss caused by the frictional resistance of the fluid in the target wellbore in each area, the calculation can be combined with the experimental data already available in the laboratory. In the laboratory, the pressure loss caused by the standard liquid flowing through the experimental wellbore of the same size can be calculated in advance, and the relationship between the displacement of the injected standard liquid and the pressure loss can be determined. If the wellbore includes three diameters, three related experiments can be performed to obtain three sets of relationships between displacement and pressure loss, and each set of relationships corresponds to the size of a diameter. In actual construction, the wellbore size of each area can be determined, the corresponding relationship between displacement and pressure loss can be found, and the pressure loss caused by the corresponding standard liquid in the relationship can be determined based on the liquid displacement at the current moment. Then, combined with the friction coefficient of the fluid in the target wellbore in this area and the pressure loss caused by the standard liquid, the pressure loss caused by the frictional resistance of the fluid in the target wellbore in this area can be determined.

[0041] As an optional embodiment, determining the mass of the proppant included in the fluid in the target wellbore includes: determining the volume of a first fluid in the fluid in the target wellbore based on multiple construction parameters, wherein the first fluid is a fluid mixed with the proppant and injected into the target wellbore from the ground; obtaining the concentration of the proppant in the first fluid; and determining the mass of the proppant included in the fluid in the target wellbore based on the volume of the first fluid and the concentration of the proppant in the first fluid.

[0042] Alternatively, the volume of the fluid mixed with the proppant can be determined based on the displacement of the injected liquid, and then the mass of the proppant included in the fluid can be determined based on the concentration of the proppant in the fluid. Subsequently, the bottom hole pressure caused by the gravity of the proppant on the target wellbore can be determined based on the mass of the proppant.

[0043] As an optional embodiment, determining the target bottom hole pressure according to the first pressure, the second pressure and the pressure loss includes: determining the target bottom hole pressure as the difference between the sum of the first pressure and the second pressure and the pressure loss. Optionally, after determining the pressure generated by the gravity of the liquid in the wellbore, the pressure generated by the gravity of the proppant and the pressure loss caused by the flow of the fluid in the target wellbore, the bottom hole pressure is the sum of the pressure generated by the gravity of the liquid and the pressure generated by the gravity of the proppant obtained by the above calculation, minus the pressure loss caused by the flow of the fluid in the target wellbore.

[0044] As an optional embodiment, the distribution of fluids in a target wellbore at a target time is determined based on multiple construction parameters, including: determining the order in which multiple liquids are injected into the target wellbore and the volumes of each of the multiple liquids injected into the target wellbore at the target time based on the multiple construction parameters; obtaining the volume of the target wellbore; and determining the distribution of the multiple liquids in the target wellbore at the target time based on the order in which the multiple liquids are injected into the target wellbore, the volumes of each of the multiple liquids injected into the target wellbore at the target time, and the volume of the target wellbore.

[0045] Optionally, the volume of the injected liquid can be determined based on the displacement of the liquid injected into the target wellbore at multiple moments recorded by multiple construction parameters. The positions of the multiple liquids in the wellbore after being injected can also be determined based on the moment when the multiple liquids are injected and the volume of the target wellbore, that is, the distribution of the multiple liquids in the target wellbore at a certain moment can be determined.

[0046] As an optional embodiment, it also includes: respectively determining multiple bottom hole pressures that the target wellbore is subjected to at other moments in the multiple moments except the target moment; and visually displaying the multiple bottom hole pressures and the target bottom hole pressure in the time sequence of the multiple moments.

[0047] Optionally, after determining the bottom hole pressure at a certain moment, the bottom hole pressures corresponding to multiple moments can be calculated, and the multiple bottom hole pressures can be plotted in time sequence for visual display. It should be noted that if the bottom hole pressure corresponding to the next moment of the target moment is calculated, the fluid distribution in the target wellbore can be updated based on the fluid distribution in the target wellbore corresponding to the target moment, and the updated fluid distribution in the target wellbore can be used for relevant calculations.

[0048] In reservoir transformation construction, bottom hole pressure refers to the pressure that the formation bears. Bottom hole pressure can be used to calculate the formation fracturing pressure, closing pressure, and evaluation and analysis after reservoir transformation, etc. It is the basis for optimizing construction and improving the process. However, due to technical and working conditions, many wells cannot directly install pressure gauges to measure bottom hole pressure, and can only indirectly guide construction through wellhead pressure (it is believed that the higher the wellhead pressure, the higher the bottom hole pressure). Guiding construction through wellhead pressure cannot take into account the composition, density differences, and friction differences of different liquids in the wellbore, and cannot consider the effect of proppants on bottom hole pressure (high wellhead pressure does not necessarily mean high bottom hole pressure). In summary, calculating the bottom hole pressure in reservoir transformation construction through construction data is of great significance to the analysis, optimization, and improvement of reservoir transformation construction.

[0049] It should be noted that, for the above-mentioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.

[0050] Through the description of the above implementation methods, those skilled in the art can clearly understand that the processing method of the construction parameters according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
