Description

Technical Field

[0001] The invention relates to the technical field of oil and gas exploration, in particular to a geological logging rock cuttings transmission analysis device. Background Art

[0002] To realize the development of oil and gas resources, the first thing is exploration. The discovery of oil and gas depends on the comprehensive analysis and judgment of the physical and chemical properties of rocks, as well as the collection and analysis of underground fluids, including color, density, viscosity, solubility, fluorescence, optical rotation, conductivity, component composition and reaction, oil and gas analysis, etc. In oil exploration, on-site geological logging has the first-hand information on oil and gas display. The discovery of oil display by geological logging analysis is based on a series of methods and means, including the display analysis of gas-measured hydrocarbons, the observation of rock oil content and rock geochemical analysis, etc. Among them, the observation of rock oil content using fluorescent lamps (ultraviolet lamps) is an important part of the daily work of geological logging. Observing whether rocks contain oil under fluorescent lamps is to use the fluorescence of oil. Oil will emit a special "light" under ultraviolet irradiation, and the luminescence phenomenon disappears when the irradiation stops. This characteristic is called the fluorescence of oil. The fluorescence of oil is related to the content of each component in the oil, and different components have different fluorescent tones. Oil is light in color, light blue or milky white, colloid is yellow, and asphalt is brown or brown. As long as there is one part per hundred thousand of oil or asphalt in the core, rock, and mud, it will show up under the fluorescent light. Therefore, fluorescent lights have become one of the indispensable and important equipment in geological logging sites. Traditional fluorescent lights have a simple structure and require almost no complicated operation and maintenance.

[0003] For a long time, on-site rock cuttings fluorescence analysis has relied on simple manual operation and subjective judgment, and it is also an intermittent operation. The on-site requirement for the fluorescence irradiation of each bag of rock cuttings requires a dedicated person to be responsible. Under normal circumstances, one person puts the rock cuttings under the fluorescent light to see if they are fluorescent. This operation mode is simple and outdated, because there is no device that can replace this simple labor process.

[0004] At the oil and gas exploration site, an important daily task for geological technicians is to perform fluorescent irradiation of rock cuttings. Underground rocks are broken by the drill bit and carried to the surface through the circulation of drilling fluid. Sand dredgers clean the rock cuttings at a certain interval, air dry them, and then dilute hydrocarbons with extractants for irradiation under fluorescent lights. During this period, operators need to frequently contact extractants with certain toxicity, including contact with the eyes and respiratory system. In this workflow, rock cuttings cleaning, air drying and air drying have been automated, while fluorescent irradiation still requires manual operation. Not all broken rock cuttings contain oil. Oil-containing rock cuttings have their own physical and chemical properties. These characteristics can often be preliminarily judged through certain parameter displays and continuous gas detection during drilling, and rock cuttings fluorescent irradiation is just another means of verification. Therefore, this simple labor occupies manpower, and in real time it can be completely achieved through automated rock cuttings irradiation. In summary, there are several problems with relying on only one staff member to perform rock cuttings fluorescent irradiation:

[0005] (1) The intermittent nature of human operations is not conducive to scientific rock cuttings fluorescence illumination and is not convenient for immediate discovery of oil and gas indications;

[0006] (2) It takes up human resources and increases labor costs;

[0007] (3) Long-term exposure to chemical extractants is not conducive to occupational health protection;

[0008] (4) It is impossible to realize automated operation, which is not conducive to the realization of standardized operation at the exploration site;

[0009] (5) It is impossible to follow the sand washing and air drying procedures, which is not conducive to improving the exploration efficiency;

[0010] (6) It is impossible to avoid the drawbacks of human manipulation and assumptions;

[0011] (7) Lowered the scientific and standardized work standards.

The non-fluorescent hard cloth slides slowly on the transmission platform as the transmission gear rotates, driving the rock cuttings dripping on it into the fluorescent light box for irradiation analysis. The irradiation results are transmitted to the remote computer image processing system via a high-definition camera, and then analyzed and stored online. It must be explained that the core of the present invention is to obtain the irradiation results, realize the real-time automation of the results of one stage in the rock cuttings analysis process, and transmit them to the remote computer image processing system via a high-definition camera, and then analyze and store them online. This subsequent analysis process does not belong to the content of the present invention, and the subsequent analysis process belongs to the conventional technology in this technical field, which will not be repeated.

[0079] The geological logging cuttings transmission analysis device is widely used in the observation and analysis of rock cuttings in geological logging during oil and gas exploration and construction. At the same time, it is also suitable for other similar related work processes. It is an important device for geological logging cuttings fluorescence analysis and an important component of remote logging.
