Description

Technical Field

[0001] The invention relates to the technical field of drilling cuttings collection, and is an intelligent collection system for logging cuttings. Background Art

[0002] In the process of geological exploration, especially in the process of oil and gas drilling, high-speed mud is required to flow through the drill pipe to the drill bit to cool the drill bit and carry the drilling cuttings to the ground. For a long time, a basic task of drilling site personnel has been geological logging / cuttings logging, which is to collect and filter out the cuttings at the vibrating screen, perform simple cleaning and drying, and then systematically observe, analyze and describe the cuttings. Combined with the data, the lithology is understood, the sequence of the underground formation is mastered, and the oil, gas and water content of the formation is preliminarily understood. Cuttings logging has played an important role in establishing rock stratigraphic profiles while drilling, geological stratigraphic division, oil and gas discovery, and safe drilling.

[0003] Currently, according to industry requirements, geological logging personnel are required to collect sand samples every 1 to 2 meters during the entire drilling process, which can generally last for dozens of days, months or even more than a year. In recent years, drilling projects have been speeding up. If industry standards are followed, during rapid drilling, a bag of sand samples must be taken every 1 minute or even less than 1 minute, and sampling must be carried out according to the drilling progress regardless of day or night, severe winter or hot summer. The labor intensity is extremely high. At the same time, cuttings logging is extremely immediate, and many geological phenomena are fleeting and cannot be reproduced. Under heavy labor intensity, field work is more likely to have irregular phenomena such as missing bags and subcontracting, which not only affects subsequent geological analysis, but also affects subsequent geological interpretation and oil and gas exploration and development effects, and has an extremely bad negative impact on the image of the logging industry. This deepens the image of low-end labor in logging, forms a vicious circle, and has an extremely adverse impact on the logging industry. In terms of cuttings analysis, the logging industry has formed a series of technical methods, and some technologies have become industry standards and are widely used on site. However, the automatic collection of cuttings has not been promoted. The automatic collection of cuttings is a technical problem that field logging personnel are eager to solve.
