Description

Technical Field

[0001] The invention relates to the field of core cutting equipment, in particular to an adjustable core cutting operating table. Background Art

[0002] During the exploration process, coring is an important task for petroleum geologists. The purpose of coring is to determine the underground oil layer or geological structure through surface research and analysis of the cores, and to accumulate first-hand geological data for the next step of development. The core is the direct physical data for obtaining the physical properties of the oil layer, the oil, gas and water content of the oil layer, and the effect of oil field development. After the core is taken out of the barrel on the ground, the petroleum geologists will carry out a series of core sorting and description work, and splitting the core into sections is an important operation.

[0003] In the process of splitting the conventional core, two to three people are usually required to work together. One person is responsible for selecting, carrying and measuring the cylindrical core, the other person puts the core into the core splitting seat with gloves and then places the splitter on the core, and the third person raises a hammer to hit the splitter to split the core; in the cutting of samples such as coring from the well wall, the conventional core cutting method cannot be applied, but can only be smashed with a hammer. The splitting of the core is divided into two ways: longitudinal and transverse, that is, transverse cylindrical surface and longitudinal cylindrical surface. There is no fundamental difference between the two operations, but the horizontal and vertical placement of the splitter or the direction of the core splitting seat. In the process of splitting the core, everyone needs to cooperate and grasp. The grip of the knife holder should not be too tight or too loose. If it is too tight, it is easy to deflect the hammer and cause a sprain of the wrist; if it is too loose, it is easy to hit the knife and hurt others. If it is held off, it will damage the core or make the core fail to meet the standard requirements. The hammer holder cannot wear gloves and must have certain hammering skills. The hammer holder must stand at right angles to the knife holder and cannot stand in a straight line with the knife holder, otherwise the knife holder will be injured. The hammer holder must have skills when hitting the hammer. Too much force or too little force will damage the core, and too little force will not break the core, so a certain amount of experience is required. During the whole work, the third person will be affected by the operation of the knife holder and the hammer holder.

[0004] In summary, the traditional core splitting method has the following important problems:

[0005] (1) There are many people involved, the operation steps are complicated, and human resources cannot be effectively saved;

[0006] (2) Personal safety is threatened and safety operation requirements are not met;

[0007] (3) The quality of core segmentation cannot be guaranteed, resulting in reduced work quality;

[0008] (4) The tools are simple and there are no standardized operating standards;

[0009] (5) Core fragments splashed, affecting the surrounding working environment;

[0010] (6) Small diameter core samples cannot be cut normally and cannot meet the needs of special operations;

[0011] (7) The operation intensity is high, which is not conducive to occupational health protection. Summary of the invention

[0012] The purpose of the present invention is to provide an adjustable core cutting operating table to address the deficiencies in the prior art, reduce the number of operators during core cutting, firmly clamp the core before cutting and decomposing, and make it easier to cut small-diameter core samples.

[0013] The technical solution is as follows:

[0015] The core cutting device is arranged on the cutting sliding support plate and comprises a cutting saw blade driven by a driving device;

[0016] The core clamping device is arranged on the core sliding support plate, including a linear slide, a core bearing member, two clamping plates, and a screw rod. The core bearing member is fixedly connected to the linear slide, the two clamping plates are slidably matched with the linear slide, the screw rod is threadedly connected to the two clamping plates, and the threaded holes on the two clamping plates rotate in opposite directions.

[0017] Furthermore, the core cutting device also includes a lifting base plate, the rear end of the lifting base plate is hinged to the cutting sliding support plate, the front end is connected with an elastic telescopic part, the elastic telescopic part is connected to the vertical rod fixedly arranged on the cutting sliding support plate, the clamping plate is also provided with an arc-shaped clamping part, the contact surface between the clamping part and the core is covered with an anti-slip layer, a guide groove is arranged along the outer side of the opening, a material guide groove is fixedly connected below the linear slide groove, the material guide groove is inclined downward and extends to the bottom of the core cutting device, and a sampling hole is provided on the side of the operating box close to the material guide groove.

[0018] Furthermore, a water receiving box is arranged at the bottom of the operation box, a sewage discharge hole is opened at the bottom of the water receiving box, and a water valve and an air valve are also arranged on the operation box.
