Description

Technical Field

[0001] The present invention relates to the technical field of coalbed methane gathering and transportation, and in particular to a management method for a coalbed methane station and a management system for a coalbed methane station. Background Art

[0002] In the coalbed methane industry, we pioneered the "three lows" surface gathering and transportation process mode of coalbed methane fields, namely "drainage gas production, wellhead metering, well-to-well serial connection, low-pressure gas gathering, station-field separation, two-site pressurization, and centralized processing". However, as the production time gradually increases, the gas volume begins to decline, and the system operating pressure decreases year by year. In the past 10 years, the pipe pressure of coalbed methane wells has dropped from 0.085MPa to 0.02-0.05MPa, and the pressure continues to drop, resulting in low operating efficiency of the gas gathering station. It is necessary to optimize the operating mode of the gas gathering station to improve the operating efficiency of the station.

[0003] Improving the operating efficiency of coalbed methane gathering and transportation stations has always been a technical challenge. First, due to the low-pressure production characteristics of coalbed methane wells, the system operating efficiency is low, and there is no method to improve the operating efficiency of coalbed methane gathering stations; the operating pressure of the gathering and transportation system is generally transported by the residual pressure at the wellhead, and the system operating pressure is determined by the production capacity of the coalbed methane well. This gathering and transportation mode is designed based on the conventional natural gas construction mode. During operation, the gradually decreasing system pressure reflects the problems of high energy consumption and low efficiency of the gas gathering station. Similarly, during the low-pressure operation, there is a situation where negative pressure inhalation of air occurs at the inlet of the gas gathering station booster equipment, and the system operation safety risk is high.

[0004] For example, patent document CN 115639083 A provides an energy consumption analysis method and system for oilfield gathering and transportation systems, which includes collecting the operating data of the oilfield gathering and transportation system, and preprocessing the operating data to obtain coordination data; establishing a mass balance model and a thermodynamic model of the oilfield gathering and transportation system according to the process flow of the oilfield gathering and transportation system; using the mass balance model, the thermodynamic model and the coordination data to establish multiple energy consumption evaluation indicators for each process equipment of the oilfield gathering and transportation system, and determining the main energy-consuming equipment according to the multiple energy consumption evaluation indicators; identifying the weak energy consumption links in the oilfield gathering and transportation system based on the main energy-consuming equipment. This scheme does not mention the reverse calculation of the outlet pressure of the gas gathering station according to the downstream operating pressure connected to the gas gathering station as described in this application, nor does it involve obtaining efficiency, power consumption and unit consumption characteristic curves according to the intake pressure of the compressor and the external gas volume.

[0005] Based on this, the inventors of the present application realized that there is still room for further improvement in the technical solutions of the current process model in terms of how to obtain the optimal operating pressure and the optimal inlet pressure, as well as the compressor operating mode and energy consumption prediction.

[0006] Therefore, a method for the safe operation of coalbed methane stations is proposed. The operating conditions of gas gathering stations are simulated, and the optimal pressure ratio is clarified through theoretical calculation of energy consumption comparison and analysis. The operating parameters of gas gathering stations are adjusted accordingly to achieve economical and efficient operation of coalbed methane gathering stations and reduce safety risks, which is of great significance.

[0020] Draw the actual characteristic curve of the compressor, which includes determining the variables of the characteristic curve to be fitted, obtaining the dependent variables of the curve to be fitted according to the energy efficiency evaluation model of the compressor, and establishing the corresponding relationship between the variables and the dependent variables.

[0042] like Figure 1 As shown, the present invention provides a management method for a coalbed methane station. Figure 1 A flow chart of an exemplary management method according to the present invention is shown, which may specifically include the following steps:

[0043] S1. Obtaining the operating parameters of the gas gathering station, wherein the operating parameters include the pressure of each component node, and obtaining the amount of gas collected by the gas gathering station;

[0044] S2. Obtain the downstream operating pressure of the gas gathering station, calculate the outlet pressure of the gas gathering station based on the operating parameters, the inflow gas volume and the downstream operating pressure, obtain the rated pressure ratio of the compressor, and obtain the inlet pressure of the gas gathering station according to the rated pressure ratio and the outlet pressure of the gas gathering station;

[0045] S3. Constructing a gas gathering station energy efficiency evaluation model according to each component node and processing process of the gas gathering station, and determining the operating parameters of each component node of the gas gathering station energy efficiency evaluation model by using multivariate regression analysis;

[0046] S4. Acquire the operating gas volume of the gas gathering station in real time, and optimize and adjust the operating parameters of the gas gathering station according to the inlet pressure of the gas gathering station, the operating parameters of the energy efficiency evaluation model of the gas gathering station, and the operating gas volume, and determine the optimal inlet pressure of the gas gathering station.

[0047] In some embodiments, the pressure of each component node includes: the pressure at the manifold, filter separator and compressor inlet in the station. By obtaining the pressure of the above component nodes and combining with other data, the outlet pressure of the gas gathering station can be calculated.

[0048] In step S2, the outlet pressure of the gas gathering station is calculated according to the following expression:

[0049]

[0050] In the formula, q v It represents the calculated flow rate of the pipeline, d represents the inner diameter of the pipeline, p1 represents the absolute pressure at the starting point of the pipeline section, p2 represents the absolute pressure at the end point of the pipeline section, Δ represents the density of the gas relative to air, Z represents the compression factor of the gas under the average pressure of the calculated pipeline section, T represents the average thermodynamic temperature of the gas, and L represents the calculated length of the pipeline.

[0051] In step S3, the gas gathering station energy efficiency evaluation model has five constituent nodes, specifically including:

[0052] Inlet manifold, front separator, compressor, rear separator and outlet unit.

[0053] The gas-gathering station energy efficiency evaluation model is a miniature model of the gas-gathering station. The essential elements in the gas-gathering station are split and reorganized into the gas-gathering station energy efficiency evaluation model, and various operating parameters of the gas-gathering station energy efficiency evaluation model are constructed according to the actual operating conditions and processing technology of the gas-gathering station.

[0054] In some embodiments, based on the analysis of historical data and on-site test results of gas-gathering stations, four gas-gathering station compressor energy efficiency evaluation models are established to form actual characteristic curves of different types of compressor units used in gas-gathering stations.

[0055] In step S3, constructing the gas gathering station energy efficiency evaluation model further includes:

[0056] An energy efficiency evaluation model for the compressor is established based on the energy utilization rate, efficiency and gas emissions of the compressor.

[0057] Obtain the compressor operation mode and energy consumption forecast of the gas gathering station under different gas volumes and different inlet pressures, and use the above data to guide on-site production operations.

[0058] The exhaust pressure of the compressor is determined by the pipeline back pressure. However, in actual operation, the exhaust pressure alone cannot truly reflect the actual characteristics of the compressor. In order to truly and comprehensively reflect the actual characteristics of the compressor, in step S3, the construction of the gas gathering station energy efficiency evaluation model also includes:

[0059] Draw the actual characteristic curve of the compressor, which includes determining the variables of the characteristic curve to be fitted, obtaining the dependent variables of the curve to be fitted according to the energy efficiency evaluation model of the compressor, and establishing the corresponding relationship between the variables and the dependent variables.

[0060] The method starts from the intake pressure and the external air volume of a single compressor respectively to obtain the actual characteristic curve of the single compressor.

[0061] like Figure 2 As shown, the actual characteristic curve of the compressor includes efficiency, power consumption and unit consumption characteristic curves. The actual characteristic curve of the compressor is a compressor power consumption-external air volume curve, and the external air volume is obtained based on the intake pressure of the compressor.

[0062] The external gas volume shows a linear positive correlation with the intake pressure within a certain pressure range.

[0063] In order to ensure the accuracy of the actual characteristic curve and to reduce the impact of occasional large changes in single operating data on the results, we obtain the actual characteristic curves of efficiency, power consumption and unit consumption from the two aspects of intake pressure and external gas volume respectively.

[0064] In order to clarify the optimal pressure ratio, a model can be established for the existing gathering and transportation system, and energy consumption comparison analysis can be performed through theoretical calculation. The pressure ratio is the ratio of the exhaust absolute pressure to the intake absolute pressure.

[0065] In step S4, the operating parameters of the gas gathering station are optimized and adjusted, including:

[0066] Simulate and calculate each component node of the gas gathering station to obtain the optimal outlet pressure.

[0067] In step S4, the operating parameters of the gas gathering station are optimized and adjusted, including:

[0068] The energy consumption data of the gas gathering station is obtained, and based on the actual characteristic curve of the compressor and the energy consumption data of the gas gathering station, the compressor operation mode and energy consumption prediction of the gas gathering station under different gas volumes and different inlet pressures are obtained, and the optimal inlet pressure is obtained based on the optimal outlet pressure, the compressor operation mode and the energy consumption prediction.

[0069] According to the gas gathering station operation parameters, the station process is simulated and calculated, and the optimal outlet pressure is calculated in reverse. Considering that the rated pressure ratio of the existing equipment ranges from 7.2 to 10, the inlet pressure of the gas gathering station compressor is determined when the downstream station has different inlet pressures, and finally the optimal inlet pressure of each station is determined.

[0070] The present invention also provides an energy consumption analysis system for a coalbed methane station, which comprises:

[0071] A data acquisition module, which obtains the operating parameters of the coalbed methane gathering and transportation system and pre-processes the operating parameters;

[0072] The first module is used to obtain the operating parameters of the gas gathering station, which include the pressure of each component node and the amount of gas collected by the gas gathering station;

[0073] The second module is used to obtain the downstream operating pressure of the gas gathering station, calculate the outlet pressure of the gas gathering station based on the incoming gas volume and the downstream operating pressure, obtain the rated pressure ratio of the compressor, and obtain the inlet pressure of the gas gathering station according to the rated pressure ratio and the outlet pressure of the gas gathering station;

[0074] The third module is used to construct a gas gathering station energy efficiency evaluation model according to the component nodes and processing processes of the gas gathering station, and use multivariate regression analysis to determine the operating parameters of each component node of the gas gathering station energy efficiency evaluation model;

[0075] The fourth module is used to obtain the operating gas volume of the gas gathering station in real time, and optimize the operating parameters of the gas gathering station according to the inlet pressure of the gas gathering station, the operating parameters of the energy efficiency evaluation model of the gas gathering station and the operating gas volume, and determine the optimal inlet pressure of the gas gathering station.

[0076] Compared with the previous operation mode, the present invention changes the previous idea that the load rate and efficiency are affected by the inlet pressure alone, and clarifies that the pressure ratio is the main control factor that comprehensively affects the efficiency and energy consumption. By comparing the deviation between the pressure ratio and the design value, the compressor pressure ratio design value is used as the control bottom line to calculate the theoretical inlet pressure.

[0077] In a management method for a coalbed methane station and an energy consumption analysis system for a coalbed methane station according to an embodiment of the present invention, on the basis of the existing technology, the operating parameters of the nodes constituting the gas gathering station are adjusted by constructing an energy efficiency evaluation model for the gas gathering station. This can reflect the actual conditions of the gas gathering station and provide the optimal operating plan, while reducing costs and increasing efficiency, thereby providing assistance for the safe and efficient operation of the gathering and transportation system.
