Description

Technical Field

[0001] The present invention belongs to the technical field of oil and gas exploration and production, and particularly relates to an optimization method, system, device and storage medium for geological analysis while drilling. Background Art

[0002] Due to the influence of objective factors such as changes in formation lithology and complex structures during drilling operations, the results of geological analysis are required as theoretical support to timely adjust various parameters and tool types in the drilling construction process. Traditional geological analysis methods require geologists to collect regional geological data, obtain data while drilling on-site, establish geological models using various stand-alone professional software, and make judgments on the formation conditions based on personal understanding of the block.

[0003] The implementation of traditional geological analysis methods requires geological experts to arrive at the site for analysis. In addition to identifying on-site cuttings and judging the formation conditions, geological experts also need to process all the data and input it into stand-alone geological analysis software to draw geological maps using the software. This analysis method requires a large amount of manpower on-site, has low data processing efficiency, and is difficult to share results.

[0004] Patent CN112943217B, a patent application named a remote intelligent logging analysis method and system, provides a remote intelligent logging analysis method, including the following steps: obtaining preset drilling geological data and generating a corresponding drilling plan; guiding drilling according to the drilling plan, obtaining drilling position data information, and matching the preset drilling geological data to form updated preset drilling geological data; further drilling after modifying the drilling plan and synchronously obtaining drilling position data information, and obtaining drilling position data information at different positions of the drilling; performing data analysis based on the drilling position data information at different positions of the drilling and sending the data analysis results to a storage terminal. Although this patent application can share results, it cannot solve the rapid processing of various types of graphic data and cannot quickly hand over the data to experts for analysis.

[0012] Optionally, before step S1, obtain the optimization work progress of the wells being drilled in each block and view the optimization results of historical wells.

[0013] Optionally, in step S1, the time-domain data includes static geological data, analytical test data, and interpretation result data.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0041] The present invention will be described in detail below with reference to the accompanying drawings.

[0042] As Figure 1 shown, a method for optimizing geologic analysis while drilling according to the present invention includes the following steps:

[0043] Optimization overview: Through the optimization overview, the status of all currently optimizing active wells can be viewed to understand the progress of the optimization work of active wells in each block; the optimization results of historical wells can be viewed as reference cases for the optimization of active wells, and the blocks, optimizers, production units, well teams, and well types of different individual wells can be marked for statistics.

[0044] Analyze a single well, and automatically generate various geologic maps in accordance with the "QSY 01128-2020 Logging Data Acquisition, Processing, and Interpretation Specification", including geologic logging maps, core logging maps, interpretation result maps, and logging-while-drilling maps. By obtaining static geologic data, analytical test data, and interpretation result data, various curves and legends are automatically generated, and through a time-depth conversion algorithm, the time-domain data collected by the black box comprehensive logging tool is real-time converted into dynamic depth-domain data. The static data and the dynamic data after time-depth conversion are spliced and displayed, and the dynamic data is used to complete the static data that is not entered in time at the site, ensuring the timeliness and accuracy of the data display in the system application. The geologists in the rear can timely master the on-site drilling dynamics and the latest geologic data through this function, and the result is as Figure 2 shown.

[0045] Cross - layer comparison: Based on the single - well analysis function, this function can select wells based on the GIS well - location map, query data according to well - location information, and automatically generate cross - well profiles. It can generate multi - well comparison diagrams between different well positions according to geological analysis needs. It supports both automatic and manual cross - layer methods and various auxiliary functions to assist in determining and predicting the horizons of working wells, providing users with a fast and convenient analysis tool. The results are as Figure 3 shown.

[0046] While - drilling guidance: Establish a databank to store drilling trajectories, formations, measurement - while - drilling (MWD), and logging - while - drilling (LWD) data. By obtaining and processing the drilling trajectories, formations, MWD, and LWD data stored in the databank, automatic generation of two - dimensional guidance profiles can be achieved. It supports the display of geological models of various common reservoirs and monitors the well being drilled in two dimensions: apparent translation and vertical depth. According to the changes in formation dip and various data curves, guidance instructions are sent to the field to promote the efficient progress of on - site work. The results are as Figure 4 shown.

[0047] Three - dimensional anti - collision: Automatically obtain the drilling trajectory data of each well in the block by the system. With the working well as the center, three - dimensional display of the trajectories of adjacent wells within the range set by the user is carried out. Custom anti - collision rules (scanning range, scanning interval, safety distance) are used to scan the trajectory of the working well. When the trajectory of an adjacent well enters the safe range, an alarm prompt is given to ensure the safety of drilling operations. The results are as Figure 5 shown.

[0048] Three - dimensional model: Obtain the trajectory and horizon data of each well in the block, make a three - dimensional structural model and upload it to the system. Through the three - dimensional structural model, the formation structure in the well area can be understood, which helps in predicting the horizons of the well being drilled. The results are as Figure 6 shown.

[0049] Result display: Display the results of geological analysis optimization, including single - well depth - domain data maps, multi - well profiles, two - dimensional guidance profiles, and plan views, facilitating the preservation and sharing of results between the field and the rear base. The results are as Figure 7 shown.

[0050] Embodiment

[0053] In the second step, according to business needs, geological experts click on the corresponding functions on the platform, and the system automatically generates geological maps based on the existing data. After the map generation is completed, experts can also perform custom operations on the map for auxiliary analysis.

[0054] In the third step, after the experts' analysis is completed, they guide the on-site work, and the analysis results will also be saved in the system for sharing.

[0055] Through the practical application of this technology, the workload of technical personnel repeatedly manually checking geological formation information during the tracking process has been greatly reduced, and the work efficiency of real-time tracking and optimization has been greatly improved, providing faster and more accurate help and guidance for on-site construction personnel, thereby reducing on-site construction risks.
