[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] In an exemplary embodiment, Figure 1 The flowchart shown provides a method for fine evaluation of gas-sand bodies based on intelligent splitting production, which is executed by a computer device and includes the following steps S1 to S5:

[0040] S1. According to the changes in the gas sand body layer and the changes in the test data profile, select the production splitting area and establish the production splitting work area in the production splitting area. In the production splitting area, it is divided into blocks, fault blocks, well groups and single wells from large to small.

[0041] S2. Select different production splitting methods according to the production splitting work area, perform production splitting processing on the production splitting work area, and obtain the production calculation results of each well in the production splitting work area. The production splitting work area includes a number of gas wells and a number of water wells.

[0042] Production splitting methods include static splitting and dynamic splitting. The static splitting method is to split the production of each well into production layers based on the static data parameters of each well formation. When the static splitting method is applied to oil wells, it includes the following two operations:

[0043] (1) Formation coefficient method, using kh for splitting, that is, using the product of the effective permeability and effective thickness of the oil layer for splitting, the unit is μm 2 ·m.

[0044] (2) Flow coefficient method, using kh / μ for splitting, that is, the ratio of formation coefficient to formation crude oil viscosity, with the unit of μm 2 ·m / (mPa·s).

[0045] The dynamic splitting rule refers to the production and absorption profile, water content, and injection-production changes of each well to split the production of each well into production sublayers, including the following three operations:

[0046] (1) Liquid production profile method: This method uses the liquid contribution rate of each layer measured in the liquid production profile of each gas well to split the gas production of each layer.

[0047] (2) Water absorption profile method, which uses the water absorption contribution rate of each layer measured in each water well absorption profile to split the water injection volume of each layer.

[0048] (3) Dynamic weight method, which is a method of splitting the production capacity and water injection volume of each layer based on the experience of dynamic personnel.

[0049] The above methods can be used individually or in combination. The staff can choose according to the actual needs of the project.

[0050] For wells with multi-layer mixed water injection, the water injection volume is initially split using the formation coefficient, and the water absorption profile is used after the water absorption profile is available. For stratified water injection wells, the weight of the stratified test data is used to split the wells that have undergone stratified testing (tracer), but when stratified testing and water absorption profile coexist, the dynamic water absorption profile shall prevail (currently, the water injection methods in oil fields are mostly tubing water injection, casing water injection, oil-casing mixed injection, or the use of eccentric water distributors to achieve multi-layer distributed water injection, but during field production, casing water injection channeling caused by lax packers or poor cementing quality often occurs, so the water absorption profile shall prevail).

[0051] For gas wells, there are several situations:

[0052] First, for wells with measured liquid production profiles, in principle, linear interpolation is performed based on the initial formation coefficient percentage and the gas and water production percentages of the liquid production profiles tested at different stages thereafter to split the gas and water production of each layer.

[0053] The second is that for an effective gas well with an unmeasured liquid production profile, production is split with the help of the corresponding water injection well water absorption profile.

[0054] Third, for remote gas wells that have neither liquid production profiles nor water injection to supplement energy, they are elastic or edge water driven and are only split using formation coefficients or flow coefficients.

[0055] The above production splitting principles are based on the assumption that there are impermeable barriers between layers, and no flow occurs between layers, that is, no fluid exchange occurs. When multiple layers are opened at the same time, the fluid of each layer flows into the wellbore separately. The fluid properties of each reservoir in a multi-layer gas reservoir are the same.

[0056] Porosity, permeability, formation thickness, formation pressure, skin coefficient, sand body size and other factors have a great influence on the stratified flow rate, and the weight of the influence varies with the change of production time. In addition, the injection and production system and other human factors also have a certain influence on the production contribution rate of each layer, which is based on the principle of splitting for specific problems.

[0057] S3. According to whether each gas well has multiple measures, the gas well is divided into one or more stages according to the type of measures, and the splitting coefficient of each small layer is calculated in stages. The types of measures include perforation, plugging, esterification and fracturing. Since the production conditions and data of the gas well are different, the splitting of the gas well is divided into several different situations. Specifically, step S3 is as follows:

[0058] The number of different types of measures taken by the gas well is determined. If the gas well only takes one type of measure, the gas well is divided into one stage; if the gas well takes multiple types of measures, the gas well is divided into multiple stages based on the time of each type of measure.

[0059] For gas wells, the splitting coefficient of each small layer is calculated in stages.

[0060] S4. Calculate the gas production and water production of each layer according to the splitting coefficient of each small layer. After splitting the production capacity and water injection of each gas well and water well according to the above process, in this step, the monthly gas production, water production and water injection of each single sand body are calculated by summarizing the same single sand body in the single sand body, and the cumulative gas production, cumulative water production and cumulative water injection values ​​of each single sand body are calculated at the same time.

[0061] S5. Generate and display the gas sand body production curve according to the gas and water production of each layer; realize real-time tracking of the gas sand body reserve utilization and analysis of the dynamic characteristics of gas sand body development. In this embodiment, through the integration of dynamic and static data, intelligent splitting and multi-dimensional statistical analysis of results, the production history of single well small layers and gas sand body production history can be reproduced conveniently and quickly, realizing real-time tracking of the gas sand body reserve utilization and analysis of the dynamic characteristics of gas sand body development.

[0062] In a specific embodiment, Figure 2 As shown, through the collation of single well perforation historical data, intelligent multi-method production splitting, monthly splitting production data of single well perforation section, monthly production data of single well sublayer, determination of the gas sand body to which the single well sublayer belongs and summarization of the production data of each gas sand body, the production curve of the gas sand body was drawn in Nanbaxian for the first time. After locating the gas sand body to which the pressure measurement data belongs and the gas sand body to which the RFT measuring point belongs, the recovery degree-pressure coefficient relationship diagram for evaluating the development effect of the gas sand body was obtained.

[0063] In some detailed embodiments, the production splitting study can obtain the following results data: a comprehensive database of single wells (mainly including: block division data, sub-layer stratification data, logging interpretation results, perforation data, liquid production profile, water absorption profile, monthly gas / water well production data), a historical production database of each perforation section of a single well (including monthly production, annual production, and cumulative production of the entire production time), a historical production database of each sub-layer of a single well, a historical production database of a single well sand group, a historical production database of each sub-layer of each fault block, and a historical production database of each sub-layer of each injection-production well group.

[0064] The main uses of production splitting results include: automatic statistics of parameters such as reservoir connectivity of blocks and injection-production well groups, water drive control degree, compilation of small layer production curves for single wells, compilation of small layer production curves for blocks or injection-production well groups, compilation of production status maps of each small layer, cumulative production maps, compilation of water content maps of each small layer, water flooding status maps, analysis of injection-production connectivity of injection-production well pairs, automatic statistics of water drive control degree of blocks and injection-production well groups, analysis of water content of each small layer, injection-production ratio, analysis of production speed, production degree, remaining recoverable reserves of each small layer, etc.

[0065] In the above method embodiment, firstly, a production splitting area is selected, and a production splitting work area is established in the production splitting area; different production splitting methods are selected, and the production splitting process is performed on the production splitting work area to obtain the production calculation results of each well in the work area; according to the production conditions of each gas well, each gas well is divided into small layers, and the splitting coefficients of different small layers of each gas well are calculated; according to the above intermediate calculation results, the production calculation results of different gas sand bodies are calculated, and the gas sand body production curve is generated for display; through the integration of dynamic production data and static data, intelligent production splitting and multi-dimensional statistical analysis of results, the production history of single well small layers and gas sand body production history are reproduced conveniently and quickly, and the real-time tracking of the reserve utilization status of the gas sand body and the dynamic characteristic analysis of the gas sand body development are realized.
