[0032] Please refer to Figure 1 The embodiments of the present application provide a method for testing production fluid profile of a multi-section fractured horizontal well in a self-flowing stage, the method comprising:
[0033] S10) determining a test instrument string based on preset process requirements to obtain well condition data;
[0034] S20) calculating conveying parameters of the test instrument string based on the well condition data, the conveying parameters comprising downhole process parameters, horizontal test parameters and uphole process parameters;

[0037] S50) generating corresponding test results based on the full-section production fluid profile test data and the sectional production fluid profile test data.
[0038] In actual construction process, corresponding test instrument string is selected according to actual situation, and the test instrument string is conveyed to target test position by cable tractor to test and collect data of the fractured horizontal well. However, as recorded in the background art, in the horizontal well with large well depth and long horizontal section, the probability of instrument falling into the well and test failure is extremely high, therefore, a reasonable and safe test method is provided, the test instrument is conveyed to the horizontal well section by the horizontal well cable tractor, the production profile of each section of the horizontal well is tested, the liquid production of each section of the horizontal well after fracturing is understood, and basis for fracturing effect evaluation is provided.
[0039] In a possible implementation, before the test, the preparation work is performed, the test instrument string is determined according to the process requirements, for example, the blowout preventer can adopt a large-diameter hydraulic grease injection sealing blowout preventer according to the characteristics of the test instrument string, the corresponding sealing pressure grade can be determined according to the pressure of the wellhead during the test, the corresponding blowout preventer passage diameter can be determined according to the maximum outer diameter of the test instrument string, and the length of the blowout preventer manifold can be determined according to the maximum length of the test instrument string. Further, well condition data is obtained, which includes but is not limited to well basic data, casing data, well trajectory, perforation condition, and fracturing construction parameters. After the above data is obtained, the test process is designed, in the embodiment of the present application, the test construction design scheme includes a test instrument string running-in process, a horizontal section test process, and a test instrument string pulling-up process, and therefore corresponding conveying parameters need to be determined.
[0040] In the embodiment of the present application, the running-in process parameters include wellhead parameters and running-in process mechanical parameters, the running-in process parameters of the test instrument string are calculated based on the well condition data, including: calculating the wellhead resistance based on the well condition data to obtain the wellhead power; determining whether the wellhead resistance and the wellhead power meet the self-weight running-in requirement; if yes, the wellhead resistance and the wellhead power are taken as the wellhead parameters; otherwise, a compensation gravity is generated based on the wellhead resistance and the wellhead power, and the compensation gravity, the wellhead resistance and the wellhead power are taken as the wellhead parameters; and the horizontal cable resistance, the horizontal cable tractor resistance and the cable friction force in the inclined section are calculated and determined, and the running-in process mechanical parameters are determined based on the horizontal cable resistance, the horizontal cable tractor resistance and the cable friction force in the inclined section.
[0041] In a possible implementation, the running-in process parameters are determined first, in the embodiment of the present application, the running-in process parameters include wellhead parameters and running-in process mechanical parameters, in the process of obtaining the running-in process parameters, the wellhead resistance of the test instrument string during the running-in process is calculated first according to the well condition data, for example, the resistance at the wellhead includes: the upward force Fp generated by the wellhead pressure, the buoyancy Fc of the instrument string in the vertical well section, and the friction force Fm of the wellhead grease injection sealing system, in the embodiment of the present application, the friction force Fm of the wellhead grease injection sealing system can be valued as 490N according to experience, specifically, the upward force Fp generated by the wellhead pressure is represented as: F p =A c ×P0×1.2=π×(D / 2) 2 ×P0×1.2, wherein A c represents the cross-sectional area of the cable of the test instrument string, P0 represents the pressure of the test instrument string acting on the wellhead, and D represents the diameter of the cable. The buoyancy Fc of the instrument string in the vertical well section is represented as: Fc =ρ 液 ×g×V 排 =ρ 液 ×g×π×(D / 2) 2 ×V c , where ρ 液 Characterized by the density of the liquid in the oil well, V c Characterized by the volume of the test instrument string.
[0042] At this time, the wellhead power is obtained. In the embodiment of the present invention, the wellhead power mainly includes the gravity G of the test instrument string. S and the gravity G of the horizontal well cable puller q , where the gravity of the test instrument string G S Gravity G of the test instrument string S Characterized by G s =m s ×g, gravity of horizontal well cable puller G q Characterized by G q =m q ×g, where m s Characterized by the mass of the test instrument string, m q Characterized by the mass of the horizontal well cable puller. During the actual running process, technicians need to determine whether the wellhead resistance and wellhead power meet the deadweight running requirements. Only when the deadweight running requirements are met, for example, when the wellhead power is greater than or equal to the wellhead resistance, can the test instrument string be lowered into the horizontal well. If the deadweight running requirements are not met, additional counterweights will be required.
[0043] And further calculate the parameters of the lowering process, first calculate and determine the horizontal cable resistance. In an embodiment of the present invention, the calculation to determine the horizontal cable resistance, the horizontal cable tractor resistance and the cable friction of the well deviation section includes: obtaining the well friction coefficient, calculating the horizontal section cable gravity and the horizontal section cable buoyancy, and calculating and determining the horizontal cable resistance based on the well friction, the horizontal section cable gravity and the horizontal section cable buoyancy; obtaining the lubricated friction coefficient between the horizontal cable and the tractor, the cable tractor mass and the tractor length, and calculating and generating the horizontal cable tractor resistance based on the lubricated friction coefficient, the cable tractor mass and the tractor length; determining the well deviation section calculation parameters, the well deviation section calculation parameters include the arc angle, the curvature radius and the friction coefficient between the cable and the casing, and calculating and generating the well deviation section cable friction based on the arc angle, the curvature radius and the friction coefficient between the cable and the casing.
[0044] In the actual calculation process, the mechanical parameters of the test instrument string during the lowering process include but are not limited to the friction force F of the wellhead grease sealing system. m, the upward force F generated by the wellhead pressure p , cable friction force F1 in the inclined section, cable resistance F in the horizontal section H , horizontal cable puller resistance F f Since the vertical section resistance is less than the instrument string gravity after the test instrument string is configured, only the horizontal section cable resistance F H , cable friction force F1 in the well inclination section, horizontal cable traction resistance F f .
[0045] In one possible implementation, first obtain the well friction coefficient f1 and calculate the horizontal cable gravity G c and the horizontal cable buoyancy F c , specifically, the horizontal cable gravity G c Characterized by G c =ρ c ×g×H v , where P c Characterized by the density of the horizontal cable in the air, H v Characterized by the depth of the vertical well section of the horizontal well, the buoyancy of the horizontal section cable F c Characterized by F c =ρ 液 ×g×V 排 =ρ 液 ×g×π×(D / 2) 2 ×H h , where H h Characterized as the forward distance of the horizontal cable puller, and further determined by the horizontal cable resistance F H , such as the horizontal cable resistance F H Characterized by F H =f1×(G c -F c ); then obtain the lubricated friction coefficient f between the horizontal cable and the tractor f , cable puller mass m q And the tractor length l q , and further calculate to determine the horizontal cable puller resistance F f , such as the horizontal cable puller resistance F f Characterized by F f =f f ×(m q ×g-ρ 液 ×g×V 排 )=f f ×(m q ×g-ρ 液 ×g×π×(D / 2) 2 ×l q ); and further calculate the cable friction force F1 in the well deviation section.
[0046] In actual calculation process, the cable force of the inclined section is more complex, the size of friction is related to the length of the cable, friction coefficient and so on, and is also affected by the external conditions such as pipe bending curvature radius, so some unimportant details need to be ignored, for example, assuming that the curved pipe is a smooth circular arc pipe, the cable can be closely attached to the inner wall of the pipe, ignoring the influence of cable weight, setting the arc angle of the curved pipe as α, the curvature radius as r, according to experience, the lubricated friction coefficient between the cable and the casing can be taken as f1=0.2. At this time, the force equation of the cable with unit length in the curved section is obtained first, for example, which can be represented as:
[0047] (F+dF)cosdα / 2-f1 dN-Fcosdα / 2=0
[0048] dN-(F+dF)sindα / 2-Fsindα / 2=0
[0049] Further arrangement obtains:
[0050] dFcosdα / 2-f1 dN=0
[0051] dN-2Fsinda / 2-dFsindα / 2=0
[0052] According to the differential theorem, when dα / 2→0, sindα / 2→dα / 2, cosdα / 2→1, that is, the above formula can be further optimized as:
[0053] dF-f1 dN=0
[0054] dN-2Fda / 2-dFdα / 2=0
[0055] Two formulas are combined to obtain: dF / f1-2Fdα / 2-dFdα / 2=0.
[0056] Neglecting the high-order infinitesimal dFdα / 2, we obtain:
[0057] dF / f1-Fdα=0
[0058] dF / F=f1dα
[0059] At this time, the integral processing can be carried out on both sides to obtain:
[0060]
[0061] Therefore, the running process mechanical parameter of the test instrument string in the running process is calculated, before the test instrument string is run in, whether the conveying condition of the test instrument string in the horizontal section meets the conveying condition is judged according to the running process mechanical parameter, and the test operation can be started only in the case that the conveying condition is met. In the actual running process of the test instrument string, the running process is designed as follows: in the vertical section, the crawler arm is first retracted, then the test instrument string tests the magnetic positioning and natural gamma data, then a certain section of the well section in the middle is selected to be run in at a constant speed, and the turbine is calibrated downhole through the turbine indication value and the speed measurement; in the inclined well section, the cable tension is observed, the crawling time is determined according to the tension change, and the test instrument is closed. In the vertical section, the test instrument is closed to ensure that the cable tractor crawls.
[0062] Further, the horizontal test parameter is calculated. Specifically, electrical measurement is performed between each section in the horizontal section, for example, the test of each measuring point is 5 minutes, and whether encryption test is needed in the section is determined according to the output of each section. If encryption test is needed, the corresponding encryption test operation is performed. Then, the pulling-up process parameter is calculated.
[0063] In the embodiment of the present application, the pulling-up process parameter of the test instrument string is calculated based on the well condition data, including: calculating and determining the friction resistance of the vertical section and the friction resistance of the horizontal section; acquiring the cable friction force of the inclined section and the cable gravity of the horizontal section; and calculating and determining the pulling-up process parameter based on the friction resistance of the vertical section, the friction resistance of the horizontal section, the cable friction force of the inclined section and the cable gravity of the horizontal section.
[0064] In a possible implementation, the pulling-up process parameter includes but is not limited to the friction resistance F v of the vertical section, the friction resistance F h1 of the horizontal section, the cable friction force F1 of the inclined section and the cable gravity G c of the vertical section. sm In the embodiment of the present application, the pulling-up process parameter is the total friction force F sm of the pulling-up process, which can be represented as F sm =F v +F h1 +F1+G c . The cable friction force F1 of the inclined section and the cable gravity G c of the vertical section can be obtained through the above technical content. At this time, the friction resistance F v of the vertical section and the friction resistance F h1 of the horizontal section are further calculated and determined according to the well condition data. For example, the friction resistance F v of the vertical section can be represented as F v =F m +F p , and the friction resistance F h1 of the horizontal section can be represented as Fh1 =F f +F H In the subsequent lifting process of the test instrument string, it is necessary to first determine whether the lifting force F of the test instrument string meets the preset lifting force condition, and the corresponding lifting operation can be performed only when it is determined that the preset lifting force condition is met, specifically, the lifting process parameters further include cable weak point tension F r and cable rated breaking force F d , and the preset lifting force condition can be F sm <F≤F r ×70%, wherein F r ≤F d ×50%-G c .
[0065] In the actual lifting process, after it is determined that the lifting process parameters of the test instrument string meet the lifting condition, the lifting process is designed as follows: in the horizontal well section, after the cable tractor climbs to the toe of the horizontal section, the climbing arm is retracted, the test instrument string tests the data such as magnetic positioning, natural gamma, temperature, pressure, flow, water content, after the upper limit of the lifting speed is determined, the lifting operation is performed; in the inclined well section, after the corresponding upper limit of the lifting speed is determined, the test instrument string tests the data such as magnetic positioning, natural gamma, and real-time monitors the tension change in the lifting process, if the tension rapidly increases, the magnetic positioning is inconsistent with the winch panel, the lifting should be stopped immediately, and after repeated lifting and lowering, the lifting is continued; in the straight well section, the corresponding upper limit of the lifting speed is further determined, and when the distance from the wellhead is 50m, the lifting test speed is adjusted to 100m / h, until the test instrument string completely enters the blowout preventer.
[0066] In the embodiment of the application, the method further comprises: determining whether the test instrument string meets a preset running-in condition based on the running-in process parameters, performing first configuration management on the test instrument string in the case that the test instrument string does not meet the preset running-in condition, and obtaining a first configured instrument string; determining whether the test instrument string meets a preset horizontal conveying condition based on the running-in process parameters and the horizontal side parameters, performing second configuration management on the test instrument string in the case that the test instrument string does not meet the preset horizontal conveying condition, and obtaining a second configured instrument string; determining whether the test instrument string meets a preset lifting condition based on the lifting process parameters, performing third configuration management on the test instrument string in the case that the test instrument string does not meet the preset lifting condition, and obtaining a third configured instrument string; determining an optimized configured test instrument string based on the first configured instrument string and / or the second configured instrument string and / or the third configured instrument string; and conveying the optimized configured test instrument string to a preset test position based on the conveying parameters.
[0067] In a possible implementation, after the delivery parameters of the above stages are determined, the corresponding optimization needs to be performed for each stage respectively, for example, for the running-in stage, after the running-in process parameters are obtained, it is determined whether the test instrument string meets a preset running-in condition, for example, the preset running-in condition is a self-weight running-in requirement of the test instrument string, if the test instrument string does not meet the self-weight running-in requirement, an additional configuration needs to be configured for the test instrument string to meet the self-weight running-in requirement; in the horizontal delivery stage, it is determined whether the crawling force F q of the cable tractor meets a preset horizontal delivery condition, for example, the preset horizontal delivery condition is F q ≥ F f +F1+F H , if the configured crawling force of the cable tractor does not meet the preset delivery condition, a corresponding configured cable tractor needs to be selected according to the preset delivery condition; and in the tripping stage, the test instrument string also needs to meet the above preset tripping condition to perform the corresponding tripping operation.
[0068] In the embodiment of the present application, through the test design and corresponding parameter calculation of the liquid production profile of the multi-stage fracturing horizontal well before testing, the instrument falling into the well and the test failure can be effectively avoided, the test safety and the test accuracy are effectively improved, and the actual needs of the technical personnel are met.
[0069] However, in the actual application process, the test well section includes a vertical well section, and as known by those skilled in the art, the cable and the casing are easily stretched and deformed due to their own gravity in the vertical well section, which will cause deviation in the actual calculation parameters and further cause deviation in the subsequent test process design, thereby increasing the risk of the test instrument falling into the well.
[0070] To solve the above technical problems, please refer to Figure 2 In the embodiment of the present application, the well condition data includes depth data, and the method further includes:
[0071] S21) obtaining the cable elongation before calculating the delivery parameters of the test instrument string based on the well condition data;
[0072] S22) optimizing the depth data based on the cable elongation to obtain the optimized depth;
[0073] S23) updating the well condition data based on the optimized depth to obtain the updated well condition data;
[0074] S24) calculating the delivery parameters of the test instrument string based on the updated well condition data.
[0075] In a possible implementation, before the conveying parameter is calculated according to the well condition data, the cable elongation is further obtained, for example, in the embodiment of the present application, the cable elongation = actual depth / 1000 x wire or cable km elongation; then the depth data in the well condition data is optimized according to the cable elongation, to obtain the optimized depth, for example, in the actual application process, the display depth = actual depth-(casing compensation distance-wellhead height-blowout preventer height+ instrument length)-cable elongation, at this time, the well condition data is updated according to the above-mentioned optimized depth, and the updated well condition data is obtained, at this time, the conveying parameter of the test instrument string is calculated according to the updated well condition data, so as to further improve the calculation accuracy of the conveying parameter.
[0076] In the actual application process, the actual environment of the horizontal well may be greatly different from the theoretical requirements, so as to cause great trouble to the actual test conditions of the test instrument string, and further increase the risk of instrument falling into the well, therefore, the risk points of the horizontal well need to be calculated, and the actual test process needs to be provided with reference.
[0077] In the embodiment of the present application, the method further comprises: determining the inclination angles of a plurality of preset test points in the well condition data; determining the inclination angle difference based on the inclination angles and the depth data; determining whether there is a larger inclination angle difference greater than a preset angle in the inclination angle difference; if yes, determining the position corresponding to the larger inclination angle difference as a risk point; and based on the risk point and the conveying parameter, sending the test instrument string to a preset test position.
[0078] In a possible implementation, first, the inclination angles of a plurality of preset test points in the horizontal well are determined according to the well condition data, and the inclination angle difference is determined according to the above-mentioned inclination angles and depth data, specifically, the inclination angle difference = (test point 2 inclination angle-test point 1 inclination angle) / (test point 2 depth-test point 1 depth) x 10, at this time, it is determined whether there is a larger inclination angle difference greater than a preset angle in all the calculated inclination angle differences, for example, in the embodiment of the present application, the preset angle is 3°, if there is a larger inclination angle difference, the corresponding position is determined as a risk point, in the subsequent conveying process of the test instrument string, the test instrument string is conveyed to a preset test position according to the risk point and the conveying parameter.
[0079] Of course, it is easy for those skilled in the art to know that the risk point also needs to be referred to in the upward lifting process of the test instrument string, which is a technical solution that those skilled in the art can easily think of on the basis of the embodiment of the present application, and therefore belongs to the protection scope of the embodiment of the present application, and will not be described in detail here.
[0080] In the embodiment of the present application, by further determining the risk points in the horizontal well during the application of the test instrument string in the horizontal well, and assisting in the transportation of the test instrument string in the horizontal well according to the risk points, the situation of being stuck or falling during the transportation is further avoided, and the safety of the test process is further improved, so as to meet the actual needs of the technical personnel.

[0082] In a possible implementation, after the test instrument string is transported to the preset test position (for example, the toe position of the horizontal well), first, the full-layer-section liquid production profile test is performed by the lifting test method, and the corresponding test data is obtained, after the test is completed, the test instrument string is lifted out, then the test data is played back and read out, and after the test data is processed by the interpretation software, the required full-layer-section liquid production profile test data is obtained, which includes the corresponding test data, test curve and interpretation result. Then the test instrument string is lowered into the toe position of the horizontal well again, and the segmented liquid production profile test is performed by the lifting test method, and the liquid production of each section is analyzed, the corresponding segmented liquid production profile test data is determined according to the production of each section, and it is judged whether the intra-section encryption test needs to be performed, if yes, the inter-section measurement point is further designed, and the corresponding encryption test is performed according to the designed measurement point, and finally the corresponding segmented liquid production profile test data is obtained. After the test is completed, the test instrument string is lifted out, and the corresponding test result is generated according to the full-layer-section liquid production profile test data and the segmented liquid production profile test data.
[0083] In the embodiment of the present application, by designing and calculating the parameters of the test process of the liquid production profile in the self-flowing stage of the multi-section fracturing horizontal well, the safety of the test instrument string in the test process is effectively ensured, the production profile of each section of the horizontal well can be accurately collected, and the liquid production of each section after fracturing can be understood, so as to provide accurate data basis for the subsequent fracturing effect evaluation.
