Description
Technical Field
The utility model belongs to the technical field of oil and gas field exploration logging engineering, and relates to a rock debris extraction device.
Background
The most important link in the traditional engineering logging rock debris logging technical work is that all rock debris is taken accurately, and only if all rock debris are taken accurately, the work such as observation, description, comprehensive explanation and the like has a reliable foundation; otherwise, these tasks cannot be performed or the resulting material is not authentic. Because the rock debris logging has the advantages of low cost, simplicity, practicability, timely understanding of underground conditions, strong systematicness of data and the like, the rock debris logging method is widely used in the exploration and development process of oil and gas fields, the rock debris fishing is still the most important irreplaceable logging method (the rock debris is the first-hand intuitive data for the system to know underground strata, lithology and oil and gas display), the traditional sampling method is always used up to now by taking one rock debris per meter, and in recent years, along with the popularization and application of new drilling technology such as air drilling, underbalanced drilling and the like, the drilling speed is faster and faster, the mechanical drilling speed is continuously improved, and the drilling time is lower and lower. When drilling, each meter is 1-2min, the steps of sampling, washing, observing, drying, screening, bagging and the like before manual sampling is sent from a geological room to a vibrating screen need about 15-20min, the sampling interval time is short, the defects are serious, on one hand, the labor intensity of sampling personnel is increased, on the other hand, the quality (distortion) of rock debris is influenced due to untimely rock debris fishing, the lithology is confused, well logging sections are accurately established on a well logging site, real stratum reduction and the like are difficult, meanwhile, a new challenge is provided for the well logging technology, the traditional sampling method obviously cannot adapt to the requirements of the existing fast drilling technology, the requirements of fast drilling technology development and exploration development are met, and continuous innovation and new well logging technology is required.
