Description
Technical Field
The embodiment of the invention relates to the technical field of measurement optimization, in particular to a measurement resolution optimization method, a device, equipment and a storage medium of a measurement device.
Background
One important technical parameter in the performance index of a measuring device is the physical measurement resolution of the measuring device. For example, in oil exploration logging, when a measuring device and a measured object (stratum) undergo relative displacement or scanning measurement, and a physical parameter measured by the measured object changes in a displacement axis direction, the measuring device is required to be capable of sensing the change of the physical parameter measured by a horizon in a scanning displacement axis and measuring the physical parameter (such as resistivity, porosity, density and the like) of the horizon. However, if the horizon thickness is less than the resolution dimension index of the measurement device, i.e., a thin layer, the information about this thin layer is averaged by the information about the nearby formation, resulting in a measurement bias. If the horizon continues to thin, the measuring device cannot even be sensitive to the presence of the horizon. The ability of petroleum exploration measuring devices to sense and measure multiple thin layers, or the ability of other measuring devices to sense and measure multiple fine particles, is the physical measurement resolution of the sonde.
In the prior art, the measurement resolution is usually improved by a physical means, but the improvement of the measurement resolution is still greatly limited, and the requirements of users cannot be met. Several factors that limit the improvement in the physical means of resolution of the measuring device include: is limited by the physical dimensions of the main detecting components in the measuring device; is restricted by the mutual conflict between the measurement precision and the measurement resolution index in the overall design of the measuring device; high resolution detection components tend to be expensive due to economic constraints.

Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a measurement resolution optimization method of a measurement device according to a first embodiment of the present invention, where the method may be performed by a measurement resolution optimization device of a measurement device, and the device may be implemented in hardware and/or software, and referring to fig. 1, the method provided by the embodiment of the present invention specifically includes the following steps:
s110, acquiring a current measurement original value of the measurement device at a current measurement point relative to the measured object by the original measurement resolution, and acquiring a last target measurement set associated with a last measurement point relative to the expected measurement resolution.
The measuring device can be regarded as a device for detecting the stratum, and the embodiment of the invention is not limited herein, and can be determined according to actual requirements; the raw measurement resolution may be understood as a low measurement resolution; the desired measurement resolution may be understood as a high measurement resolution, typically the desired measurement resolution size is smaller than the original measurement resolution size of the measurement device; the previous target measurement set may be regarded as a set of high-resolution measurement values of a plurality of horizons corresponding to the original measurement value of the previous measurement point after measurement optimization. Of course, in the case of a homogeneous medium, the measured value corresponding to the original measurement resolution and the measured value corresponding to the desired measurement resolution are equal.
It should be noted that, the measurement device and the measured object can relatively displace from the last measurement point to the current measurement point, and the displacement can be linear displacement, circumferential scanning displacement or other displacement modes, and the measurement of the larger measured object by the measurement device can be completed through the relative displacement.
According to the embodiment of the invention, the current measurement original value corresponding to the original measurement resolution of the current measurement point of the measured object can be obtained through the obtaining measurement device, and the last target measurement set corresponding to the expected measurement resolution of the last measurement point can be obtained, so that the subsequent optimization of the current measurement original value of the current measurement point is facilitated.
S120, determining a current target measurement set of the measuring device relative to the current measurement point under the expected measurement resolution according to the current measurement original value and the last target measurement set and combining a predetermined contribution factor sequence.
It should be noted that, the measurement original value corresponding to the original measurement resolution may be combined with the measurement device to pre-determine the contribution factor sequence of the relevant desired measurement resolution size partition in the uniform medium measurement model. Within the original resolution measurement range of the measurement device, the contribution of each measurement unit of the measured formation to the original value of the measurement is different. The stratum in the original measurement range is divided into a plurality of horizontal measurement target disks perpendicular to the measurement displacement direction according to the dimension of the expected measurement resolution, and the unit contribution values in all the target disks are accumulated, namely the contribution factor values of the horizontal measurement target disks are formed. Typically, the contribution factor of the target disc at the measurement point of the corresponding measurement device is maximized and then gradually decreases as the distance of the target disc from the measurement point of the measurement device increases until it is zero, exhibiting a distribution of the contribution factor-dependent displacement axes of a normal or near normal distribution. Of course, all the contribution factor series additions should be equal to 1, the different contribution factors representing the contribution of the respective target formation to the measurement raw value of the measurement point of the measurement device.

By taking petroleum logging as an example, the measuring device can be equivalent to a logging instrument, the measured object can be a stratum of 10 ohm meters, the current measurement original value of the current measuring point can be obtained through the measuring device, when the layer thickness is smaller than the original resolution of the measuring device, the measurement original value often has a certain deviation from the stratum true value, especially when the layer thickness is far smaller than the resolution width of the measuring device, the deviation between the measurement original value and the stratum true value is larger, and the optimized measured value can be regarded as a measured value which is more similar to the actual measured value, therefore, the set of the measured value corresponding to the high measurement resolution of the current measuring point can be obtained by acquiring the measured value corresponding to the high measurement resolution of the optimized last measuring point and combining the measurement original value of the current measuring point and a predetermined contribution factor sequence.

d1, arranging the contribution factor quantities according to the sequence of the measurement displacement direction to form a contribution factor sequence containing the contribution factor quantities.
According to the embodiment of the invention, the contribution factor quantities can be sequentially arranged according to the measurement displacement direction, so that a contribution factor sequence containing the contribution factor quantities is formed. The method is convenient to follow and can be used as one of the basis for calculating the current target measurement set of the measuring device relative to the current measurement point under the expected measurement resolution.
Further, on the basis of the above embodiment, the previous target measurement set includes a set number of previous target measurement values arranged in order according to the measurement displacement direction, where the set number is equal to the number of contribution factor amounts included in the contribution factor sequence.
In the embodiment of the present invention, the previous target measurement set may include a set number of previous target measurement values arranged in order according to the measurement displacement direction, where the set number is equal to the number of contribution factor amounts included in the contribution factor sequence. It is correspondingly understood that each target measurement has a corresponding contribution factor.
S220, determining a current contribution displacement interval related to the relative measurement displacement track when the measurement device measures at the current measurement point with the original measurement resolution.
The measured displacement trajectory may be considered as a displacement trajectory formed by measuring points corresponding to the displacement measuring device several times at the original measurement resolution.
According to the embodiment of the invention, the current contribution displacement interval related to the measurement displacement track can be determined when the measurement device measures at the current measurement point under the original measurement resolution, so that the current contribution displacement interval can be conveniently divided into a plurality of contribution displacement subintervals.

The embodiment of the present invention is not limited herein with respect to a specific set number, and may be, for example, 3 or 10. Of course, the sum of the target contribution factor amounts of the respective contribution displacement sub-sections corresponding to the current contribution displacement section is 1.
S240, starting from the second one of the previous target measurement values included in the previous target measurement set, obtaining a set number minus 1 previous target measurement value, and sequentially serving as a subinterval measurement value of the previous set number minus 1 contribution displacement subinterval.
The current measurement point may be regarded as a measurement point obtained by shifting the previous measurement point by the interval of the contribution shift subinterval.
In the embodiment of the invention, the number of the previous target measurement values obtained by subtracting 1 from the set number can be obtained from the second one of the previous target measurement values included in the previous target measurement set, and can be sequentially used as the sub-interval measurement values of the contribution displacement sub-interval of the number of the previous set number subtracted by 1 corresponding to the current measurement point, and can be also understood as the current target measurement values of the number of the previous set number subtracted by 1 included in the current target measurement set of the current measurement point.
S250, taking the current measurement original value, each target contribution factor quantity and each subinterval measured value as the known value of a given measurement formula, and determining the subinterval measured value of the last contribution displacement subinterval.
The measurement formula may be a formula established according to each upper and lower measurement point, and each measurement point may be a measurement point obtained by moving a previous measurement point according to an interval of a contribution displacement subinterval. The measurement original value of the measurement point may be equal to the product of each subinterval measurement value and the corresponding target contribution factor amount, for example, each subinterval measurement value of the measurement point a is 10, 10 and 10, respectively, the corresponding target contribution factor amount is 0.25, 0.5 and 0.25, respectively, and the measurement original value t=0.25×10+0.5×10+0.25×10=10 of the measurement point a.

According to the technical scheme, the original measurement resolution of the measuring device is obtained relative to the current measurement original value of the measured object at the current measurement point, and the last target measurement set associated with the last measurement point relative to the expected measurement resolution is obtained; determining a current contribution displacement interval related to a relative measurement displacement track when the measurement device measures at a current measurement point with original measurement resolution; dividing the current contribution displacement interval into a set number of contribution displacement subintervals, and selecting a target contribution factor quantity corresponding to each contribution displacement subinterval from a contribution factor sequence; starting from the second of the previous target measurement values included in the previous target measurement set, obtaining a set number minus 1 previous target measurement value, and sequentially serving as a subinterval measurement value of the previous set number minus 1 contribution displacement subinterval; taking the current measurement original value, each target contribution factor quantity and each subinterval measurement value as the known value of a given measurement formula, and determining the subinterval measurement value of the last contribution displacement subinterval; and summarizing the measured values of all subintervals according to the sequence of the measured displacement directions to form a current target measurement set of the measuring device relative to the current measurement point under the expected measurement resolution. According to the technical scheme, the displacement measuring device takes one contribution displacement subinterval as a unit, and the subinterval measured value of each contribution displacement subinterval of the measuring point is calculated, so that the problem of low resolution of the measured value measured by the measuring device is solved, and the measuring resolution of the measuring device is effectively improved.
Further, on the basis of the above embodiment, determining the current contribution displacement interval associated with the relative measurement displacement track when the measurement device measures at the current measurement point with the original measurement resolution includes:
a2, taking the current measurement point as a center, and intercepting a displacement interval section corresponding to the original measurement resolution on the measurement displacement track.
It should be noted that, the original measurement value of the measurement device at the measurement point may be a measurement value at the original measurement resolution corresponding to the displacement interval section centered on the measurement point. Therefore, the displacement interval corresponding to the original measurement resolution can be cut off on the measurement displacement track with the current measurement point as the center.
And b2, taking the displacement interval section as a current contribution displacement interval of the relative measurement displacement track at the current measurement point.
According to the embodiment of the invention, the displacement interval corresponding to the current measurement point can be used as the current contribution displacement interval of the relative displacement track at the current measurement point.
Further, on the basis of the above embodiment, when the current measurement point is the initial measurement point, the previous measurement point is empty, and the previous target measurement set is a predetermined initial target measurement set, including a set number of initial target measurement values.
It should be noted that, if the current measurement point is the initial measurement point and the previous measurement point is empty, the corresponding previous target measurement set may be a predetermined initial target measurement set, and of course, the initial target measurement set may also include a set number of initial target measurement values, so that the formula corresponding to the initial measurement point may be satisfied according to the measurement original value of the initial measurement point, the corresponding contribution factor, and the initial target measurement value.
Further, on the basis of the above embodiment, the step of determining the initial target measurement set includes:
a3, acquiring a preset initial measurement original value, and selecting the contribution factor quantity of the set quantity included in the contribution factor sequence as an initial contribution factor quantity.
In the embodiment of the invention, the preset initial measurement original value can be acquired first, and the contribution factor quantity which can comprise the set quantity is selected from the contribution factor sequence as the initial contribution factor quantity.
And b3, under the condition that all initial target measured values are constrained to be the same, taking the initial measurement original value and all initial contribution factor quantities as known values of a measurement formula to obtain initial target measured values, and forming an initial target measurement set containing a set number of initial target measured values.
It should be noted that, the interval of the uniform medium may be found first, so that each initial target measurement value may be constrained to be equal, and the initial measurement original value and each initial contribution factor amount may be used as the known value of the measurement formula, so that a certain initial target measurement value may be calculated, which is equivalent to calculating each initial target measurement value, so that each initial target measurement value may form an initial target measurement set including a set number of initial target measurement values.
Further, on the basis of the above embodiment, the method further includes:
when the measurement ending condition of the measuring device is met, forming a target measurement result of the measuring device relative to the measured object based on a target measurement set corresponding to each measuring point under the expected measurement resolution.
The measurement end condition may be that a target measurement set at a desired measurement resolution may be acquired by moving a last measurement point corresponding to the measurement device.
According to the embodiment of the invention, when the target measurement set corresponding to the last measurement point under the expected measurement resolution can be obtained, the target measurement set corresponding to all measurement points under the expected measurement resolution is equivalent to each target measurement set corresponding to all measurement points under the expected measurement resolution, so that the target measurement result, namely the high-resolution measurement result, of the measurement device relative to the measured object can be formed based on each target measurement set corresponding to each measurement point under the expected measurement resolution.
Taking one-dimensional measurement curve resolution improvement calculation as an example, the implementation steps of the embodiment of the invention are as follows:
step one: and obtaining a measurement contribution factor distribution curve, and dividing into grids to obtain the contribution factor quantity of each displacement subinterval.
Fig. 3 is a schematic diagram illustrating an implementation effect of a contribution displacement subinterval in a measurement resolution optimization method of a measurement device according to an embodiment of the present invention.
As shown in fig. 3, the measurement parameter obtained by the measurement device 304 from the object 30 to be measured can be regarded as the total contribution amount of the displacement section 305 of the object 30 to be measured on the displacement direction axis 302. Of this total contribution, the contribution is generally greatest corresponding to where the measurement point 301 (often the geometric center of the measurement device) of the measurement device 304 corresponds, and then extends its contribution outward, gradually decreases, and finally decreases to zero or negligible. The measurement contribution factor profile 303 may be mathematically derived in a medium of uniform measured value characteristics, but different types of detection devices have different measurement contribution factor profiles 303.
The contribution displacement interval 305 is an interval of the measuring device 304 under the original measurement resolution, and the contribution displacement interval 305 is divided into n equal length sections, so as to obtain n contribution displacement sub-intervals 306, and the size of the contribution displacement sub-intervals 306 is the resolution size desired by the user. Each contributing displacement subinterval 306 is then calculated contributing factor ai? i=1, 2...n.), at the same time: sigma a i =1; typically, for ease of calculation, the contribution displacement subinterval size may be selected to be the minimum data acquisition interval length, or a multiple of the minimum data acquisition interval length. Of course, the minimum data acquisition interval length is smaller than the original resolution size of the measurement device 304, for example, the size of the contribution displacement interval 305 is 1 meter, the size of the contribution displacement subinterval 306 is 0.1 meter, and the contribution displacement subinterval 306 can be divided into 10 equal-length contribution displacement subintervals 306.
Step two: and (3) moving at intervals according to the contribution displacement subintervals, and establishing a correlation formula between the upper measuring point and the lower measuring point.
When the measuring device is located at a certain point (starting point 1), it measures the original value T 1 Can be described as:
T 1 ＝Σ(a i *τ i )(i＝1,2.....n) (1)
wherein τ i The target measurement value at the desired measurement resolution that should be applied for the corresponding contribution displacement subinterval i. In the equation (1), there are (n) unknown amounts τ i 。
When the measuring device moves to the next (2 nd measuring point), its measured valueT 2 Can be described as:
T 2 ＝Σ(a i *τ i+1 ) (i＝1,2.....n) (2)
similarly, when the measuring device moves to the mth measuring point, the measured value T thereof m Can be described as:
T m ＝Σ(a i *τ i+m ) (i＝1,2.....n) (3)
the set of equations thus established may be:
the system of equations has (m) equations, (n+m-1) variables.
Step three: and finding out proper constraint conditions according to different measurement objects and actual conditions.
According to the actual measurement situation, supplementing (n-1) constraint conditions, and together with the equation set (4), constructing (n+m-1) equations so as to meet the solution of (n+m-1) variables.
Assuming that the measuring point 1 is in a completely homogeneous measuring medium, then there is:
τ 1 ＝τ 2 ＝τ 3 ＝......＝τ n (n-1 equality in total)
Step four: solving an equation to obtain a target measurement value of the contribution displacement subinterval, and obtaining a high-resolution measurement result.
