[0002] Oil well production enhancement methods include two types: tangible and intangible. Intangible production enhancement refers to methods that increase production without maneuvering the tubing or taking aggressive measures. Its advantages include low cost and no impact on production rate. Currently, well selection for intangible production enhancement relies mainly on manual experience, lacking a scientifically effective tangible method. One limitation of existing patented technologies is that they are only applicable to pump efficiency potential analysis, a single-factor analysis method, and are not suitable for analyzing and evaluating the intangible production potential of wells with wax deposition or high casing pressure. A second limitation is that it focuses on detecting reservoir potential through logging data, well location, and water energy, but cannot analyze and detect the potential of engineering factors such as operating conditions and pump efficiency.

[0003] Therefore, existing methods for analyzing and evaluating the intangible production potential of rod pump wells in oil pumping units suffer from the problem of relying on a single evaluation factor, making effective analysis and detection impossible. Summary of the Invention

[0047] The intangible production potential of the current rod-pumped well is calculated based on the candidate set and the weighted coefficient set.

[0048] To more clearly explain the method for analyzing and evaluating the intangible production potential of rod-pumped wells of the present invention, the following will be combined with... Figure 1 The steps in the embodiments of the present invention will be described in detail below.

[0049] The method for analyzing and evaluating the intangible production potential of a rod-pumped well in the first embodiment of the present invention is described in detail below:

[0050] A first-level factor set is defined to influence the intangible production potential of the current rod pump well, and a second-level factor set is defined based on the first-level factor set.

[0051] In this embodiment, the first layer of factor set is:

[0052] U = {U1, U2, U3} = {Reservoir factors, wellbore factors, economic factors};

[0053] U1 is the first factor set in the second-level factor set, U2 is the second factor set in the second-level factor set, and U3 is the third factor set in the second-level factor set.

[0054] In this embodiment, the second layer of factor set includes:

[0055] U1 = {U11, U12, U13} = {Geological reserves, oil recovery index, water content};

[0056] U2 = {U21, U22, U23} = {pump diameter, operating conditions, submersion depth};

[0057] U3 = {U31, U32, U33} = {Daily oil production, pump efficiency, parameter adjustment cost}.

[0058] Determine the evaluation value of each factor set in the second-level factor set for the intangible property potential, and calculate the alternative set based on the evaluation value of each factor set in the second-level factor set for the intangible property potential.

[0059] In this embodiment, determining the evaluation value of each second-level factor set for the intangible asset potential includes:

[0060] The evaluation value of the intangible production potential based on the first set of factors is: V1 = the evaluation value of the intangible production potential based on reservoir factors {geological reserves, oil recovery index, water cut}.

[0061] The evaluation value of the intangible production potential based on the second set of factors is: V2 = the evaluation value of the intangible production potential based on wellbore factors {pump diameter, working system, submersion}.

[0062] The evaluation value of the intangible production potential based on the third factor set is: V3 = Evaluation value of the intangible production potential based on economic factors {daily oil production, pump efficiency, intangible production costs}.

[0063] The evaluation values ​​of each factor in the first, second, and third factor sets for intangible property potential can be obtained in the following way: Pearson correlation analysis is performed on each factor in historical data and intangible property potential to obtain the Pearson correlation coefficient of each factor and intangible property potential. Then, the Pearson correlation coefficients of each factor in each factor set are added together to obtain the evaluation value of each factor set.

[0064] In this embodiment, the alternative set is: V i = (V1, V2, V3);

[0065] Among them, V i For the alternative set.

[0066] Determine the influence weight coefficients of each influencing factor in the second layer factor set on the intangible industrial potential; construct a weight coefficient set from all the influence weight coefficients.

[0067] The intangible production potential of the current pumping unit rod pump well is calculated based on the alternative set and the weight coefficient set.

[0068] In this embodiment, the method for calculating the intangible production potential of the current rod pump well is as follows:

[0069] Where Z represents intangible potential for upward mobility, and V represents... i As an alternative set, R ij Let R be the set of weight coefficients. 11 The weighting coefficient R for the influence of geological reserves on the intangible production potential. 12 R is the weighting coefficient for the impact of the oil recovery index on the intangible production potential. 13 R is the weighting coefficient for the influence of water content on the intangible productivity potential. 21 R is the weighting coefficient for the influence of pump diameter on the intangible production potential. 22 R is the weighting coefficient for the impact of the work system on the intangible productive potential. 23 R is the weighting coefficient for the influence of submersion degree on the intangible potential for industrial development; 31 R is the weighting coefficient for the impact of daily oil production on the intangible production potential. 32R is the weighting coefficient for the impact of pump efficiency on the intangible production potential. 33 The weighting coefficient for the impact of parameter tuning costs on the intangible production potential.

[0070] The influence weight coefficients of the intangible resource potential mentioned above can all be obtained through linear regression. Taking geological reserves as an example, based on historical data, intangible resource potential is used as the dependent variable and geological reserves are used as the independent variable. A linear regression analysis is performed on geological reserves and intangible resource potential to obtain a linear equation in one variable. The coefficients of the independent variables in the equation system are the original weights of geological reserves. The original weights of each independent variable are added together to obtain the sum of the original weights. The influence weight coefficient of each independent variable is obtained by dividing the original weight of each independent variable by the sum of the original weights.

[0071] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such an order. They can be executed simultaneously (in parallel) or in a reverse order. These simple variations are all within the protection scope of this invention.

[0075] The weight coefficient set determination module is used to determine the influence weight coefficients of each influencing factor in the second layer factor set on the intangible industrial potential; and to construct a weight coefficient set from all the influence weight coefficients.

[0076] The intangible production potential determination module is used to calculate the intangible production potential of the current pumping unit rod pump well based on the alternative set and the weight coefficient set.

[0082] This invention also proposes an example of a method for analyzing and evaluating the intangible production potential of rod pump wells using a pumping unit, specifically:

[0083] A well, F1601, with intangible production potential of a rod pump well to be evaluated, was selected.

[0084] (1) Identify the influencing factors of intangible property potential;

[0085] First-level factor set: U = {U1, U2, U3} = {reservoir factors, wellbore factors, economic factors};

[0086] Second layer factor set: U1={U11,U12,U13}={Geological reserves=2.07 million tons, oil recovery index=0.48t / (dmMPa), water cut=11%};

[0087] U2 = {U21, U22, U23} = {pump diameter = 38mm, working cycle = 4.2m * 1.5 cycles, submersion depth = 230m};

[0088] U3 = {U31, U32, U33} = {Daily oil production = 1.33t / d, pump efficiency = 18.9%, parameter adjustment cost = 200 yuan};

[0089] (2) Determination of the alternative set and weighting coefficients;

[0090] The alternative set Vi represents the evaluation value of each set of influencing factors at the second level for intangible property potential.

[0096] Define the evaluation matrix:

[0097] The calculated result is that the well's intangible production potential is 93.

[0098] After evaluation using this method, the well showed significant potential for intangible production growth. Therefore, the number of strokes was adjusted from 1.5 to 2.0. Before the adjustment, the daily fluid production was 1.9 m³ / d and the oil production was 1.33 t / d. After the adjustment, the daily fluid production was 3.99 m³ / d and the oil production was 3.55 t / d, resulting in a daily oil production increase of 2.22 t / d. This demonstrated a significant effect in increasing intangible production.
