Description

Technical Field

[0001] The invention belongs to the technical field of oil and gas well production enhancement, and in particular relates to an automatic metering system and method for a fracturing proppant. Background Art

[0002] Hydraulic fracturing is currently the most widely used single-well production and injection technology, and plays a vital role in the field of oil and gas well production enhancement measures. Among them, fracturing proppant is the only substance expected to remain in the reservoir after fracturing. The type and quantity of fracturing proppant are important criteria for evaluating the quality of fracturing projects and are key indicators affecting the fracturing effect. However, the current traditional method of measuring fracturing proppant is mainly to manually record and measure the type and quantity of proppant, report the data to the project party A, and keep the handwritten record receipt. This method has the disadvantages of no intelligent counting, no accurate measurement, no real-time statistics, and difficulty in tracing, and has long failed to meet the needs of modern fracturing construction operations.

[0003] It is particularly important to effectively improve the intelligent management level of fracturing operations, realize the overall monitoring and automatic measurement of the amount of fracturing quartz sand, and provide data support for the subsequent refined construction control of fracturing proppants. At present, there is no system or device for automatic measurement of proppants in the field of fracturing production increase. When automatic measurement methods or devices in other fields are applied to proppant measurement, there are problems such as low precision and accuracy in the detection of proppant types and quantities, and the inability to trace the data related to proppant types and quantities. Summary of the invention

[0060] S2: The fracturing monitoring module sends a "start" command to the data processing module. After receiving the command, the data processing module starts the fracturing proppant automatic metering system, and each module of the system enters the working state;

[0061] S3: The sand level metering module of the sand conveyor obtains and sends the sand storage data of the sand conveyor to the data storage module and the data processing module;

[0062] S4: The wireless electronic weighing module and the proppant pattern recognition and metering module are started to identify and measure the proppant hoisted to the sand conveyor, and send them to the data storage module and the data processing module;

[0063] S5: The data processing module analyzes and processes the sand storage data of the sand conveyor, the proppant weight and the proppant type to obtain the proppant type and proppant weight entering the well and sends them to the fracturing monitoring module;

[0064] S6: The fracturing monitoring module detects that the proppant injection program is finished and sends a finish signal to the data processing module;

[0065] S7: The data processing module performs summary analysis and calculation. The data processing module obtains the proppant data used for fracturing construction based on the proppant type and proppant weight entering the well, and sends the proppant data used for fracturing construction, i.e., the final total amount and type of proppant, to the fracturing monitoring module. The process data and image data are stored and backed up by the data storage module;

[0066] S8: Based on the oil well and reservoir conditions, the fracturing proppant usage data is designed. The fracturing monitoring system reviews the quantity and type of fracturing proppant results. If review is required, a command is sent to the data processing module to verify and review the data. After the final data is confirmed to be correct, a sleep command is sent to the data processing module, and the fracturing proppant automatic metering system enters the sleep state and completes the metering.

[0067] The above-mentioned designed fracturing proppant usage data is shown in the following Table 1. The fracturing proppant is subdivided into pressure grades according to the requirements. When the designed grade proppant is insufficient during on-site construction, it can be used at a higher grade, but it is not allowed to use it at a lower grade.

[0075] Among them, the proppant bag can be set with different colors, words or symbols to indicate the type of material in the bag, so as to avoid the problem of being unable to distinguish when lifting multiple materials.

[0076] The data processing module can analyze multiple graphics to more accurately determine the number of bags. Comparative analysis is performed through top collection graphics and multiple side collection graphics to prevent the problem of missing or misrecording the number of bags due to obstruction between packaging bags.
