Description

Technical Field

[0001] The invention relates to the technical field of oil and gas field exploration, and in particular to an automatic sand bailing analysis system and a control method for oil and gas exploration. Background Art

[0002] Geological logging is an indispensable basic work in the process of oil and gas field exploration and development. In the process of oil and gas exploration and development drilling, direct detection of cuttings and drilling fluid is an important means to timely understand the underground geological conditions and directly and accurately collect various underground geological information to achieve geological purposes. As one of the main detection objects of geological logging, underground geological information mainly includes cuttings separated by vibrating screens, gas components in mud analyzed by desorbers, and hydrocarbon substances in drilling fluids. Cuttings logging is a logging technology that systematically collects cuttings during drilling, observes and describes petrological characteristics and water information, and restores underground stratigraphic profiles. The main processes include continuous cuttings collection, washing cuttings with hydrocarbon-free water, drying cuttings, observing and describing cuttings, bagging, labeling, and boxing.

[0003] At present, there are the following problems in the on-site construction of geological logging:

[0004] 1) Consume a lot of manpower and material resources: 1 to 2 full-time personnel are needed to dredge the sand. When the footage is fast, the dredge workers need to work repeatedly back and forth. In this process, not only the labor cost is increased, but also the risk of affecting safe production and obtaining data with quality and quantity is increased. In addition, a large amount of hydrocarbon-free water is required for manual cleaning of cuttings, resulting in a waste of water resources. 2) The quality of cleaning cuttings does not meet the standards: Due to the large amount of chemical reagents in the drilling fluid and the special rock properties, the cuttings are particularly difficult to clean, which greatly reduces the work efficiency and increases the risks of untimely dredge of subsequent cuttings and substandard cleaning quality. 3) Subcontracting of missed cuttings: When the footage is fast / the dredge workers miss the time for dredge, etc., the cuttings are missed. In order to make up for the negligence, the on-site staff manually subcontracts the cuttings, resulting in errors in the geological information obtained. 4) Inconsistent description of lithology identification: Lithology identification is a technical task. In principle, the rock cuttings of a well need to be completed by one person. However, the complex on-site construction situation makes it difficult to achieve the above requirements, resulting in inconsistent standards for rock cuttings lithology identification, which affects the quality of subsequent data and guidance for subsequent construction. 5) Inconsistent labels, fonts, etc. affect the appearance of on-site results: Given that everyone has unique writing habits and behavioral habits, on-site results often do not look good. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an automatic sand bailing analysis system and control method for oil and gas exploration, which can effectively save manpower, ensure the authenticity and reliability of the quality of rock cuttings, save time, reduce the solid content of mud, improve efficiency, and make the analyzed data more accurate.
