Description
Technical Field
The invention relates to the field of core cutting equipment, in particular to an adjustable core cutting operation table.
Background
During exploration, well drilling and coring are important work of petroleum geologists, and coring is to judge the condition of an underground oil reservoir or a geological structure through surface research and analysis of the cored core and accumulate geological data of one hand for further development. The core is the direct physical property data for obtaining the physical property of the oil layer, the oil-gas-water condition of the oil layer, the development effect of the oil field and the like. After the core is taken out of the barrel on the ground, petroleum geologists need to carry out a series of core arrangement and description work, and the core segmentation and splitting is an important operation.
The method comprises the following steps that two to three persons are generally required to work and cooperate in the segmented splitting process of conventional core arrangement, one person is responsible for selecting, moving and measuring a cylindrical core, the other person with gloves puts the core into a core splitting seat and then puts a cleaver on the core, and the third person lifts an iron hammer to smash the core towards the cleaver so as to split the core; the conventional core cutting method cannot be applied to cutting of a borehole wall coring sample, but only crushing by using a hammer. The splitting of the rock core is divided into a longitudinal mode and a transverse mode, namely a transverse separating cylindrical surface and a sequential extending cylindrical surface, the two operations are not fundamentally different, and only the problem of transverse and longitudinal placement of a riving knife or the problem of the direction of a rock core splitting seat is solved. In the process of splitting heart, each person needs to cooperate and hold. The force of the knife holder for holding the knife cannot be too tight or too loose, so that the knife is easy to be hammered off and the wrist of a person is twisted; if the core is too loose, the cutter is easy to fly away to hurt others, and if the core is held in a deviated way, the core can be damaged or cannot meet the standard requirements. The hammer holder cannot carry gloves and needs to have certain hammer using skill, the hammer holder needs to stand at a right angle with the knife holder and cannot be in line with the knife holder, otherwise the knife holder can be injured; the hammer holding person needs to have skill to smash the hammer, the force is too large or too small, the core is smashed by too large force, and the core is not broken by too small force, so certain experience is needed. During the whole work, the third person can be influenced by the operation of the knife holder and the hammer holder. In summary, the conventional core splitting method has the following important problems:
(1) the number of participators is large, the operation steps are complicated, and the manpower resource cannot be effectively saved;
(2) the personal safety is threatened and does not accord with the safety operation requirement;

(4) the tool is simple and crude, and has no standardized operation standard;
(5) the rock core fragments splash, and the surrounding working environment is influenced;
(6) the small-diameter core sample cannot be cut normally and cannot meet the requirements of special operation;
(7) the operation intensity is high, which is not beneficial to the occupational health protection.
