Follow-up adjustable geological rock debris receiving box

Technical Field

The utility model relates to a rock fragment that is arranged in oil and gas exploration geological logging drags for washing preparation work takes over and gets device specifically is a follow-up adjustable geology rock fragment and connects and get the case.

Background

The logging technology and means cannot be opened for oil and gas exploration and development, the rock debris logging is the foundation for recovering a stratum profile and carrying out fine geological research, is a precondition for geochemical logging and geological test analysis, is the most direct means for evaluating the exploration and development effects in real time, and is the most basic and important logging technical method. The lithology description and the naming are the important content and the main technical work of the rock debris logging, and the quality of the lithology description and the naming directly influences the level of the rock debris logging, thereby influencing the exploration and development. In a word, the rock debris logging is an important part of the conventional work of geological logging, and the fishing, washing and screening of the rock debris are the prerequisite foundation of the rock debris logging. Underground rock is broken into rock fragments with different particle sizes by the drill bit and returns upwards in the annular space along with the drilling fluid until reaching the ground. After the rock debris returns to the ground, the rock debris enters the processes of fishing, washing, primary screening and preparation, which is the manual operation process of operators.

The vibrating screen is important solid control equipment, rock debris and drilling fluid are separated after being vibrated on the vibrating screen, the rock debris is filtered and vibrated by a certain mesh number of vibrating screen cloth and falls into a waste tank, and the separated drilling fluid enters a recycling process. Under a conventional mode, rock debris filtered out by an upper screen of a vibrating screen falls into a sand receiving basin of a geological logging well in a vibrating mode, and sand bailers baile the washed rock debris according to a certain distance. The sand receiving basin is generally a round or square metal basin and is placed at a place where rock debris can be normally received according to the vibration falling condition of the rock debris, and therefore the position of the sand receiving basin needs to be adjusted in real time along with the change of the use of the vibrating screen. In the process, the sand bailer repeatedly performs simple mechanical work, and the position of the sand receiving basin directly influences the quality of the rock debris bailing. Therefore, in order to liberate the labor resources occupied by the simple labor, the sand receiving basin needs to be newly designed so as to improve the automation level of operation and optimize the construction benefit.

The drilling fluid vibrating screen is an important solid control device, is also a basic and fundamental device for carrying out rock debris fishing in geological logging, and can not fish rock debris when the vibrating screen is separated from the geological logging in oil-gas exploration with the drilling fluid as a medium. The drilling fluid carries the detritus broken through the shaft bottom drill bit and returns the well head, then flows through the overhead tank and enters into the buffer tank, and the drilling fluid enters into the buffer tank and is advanced high-altitude, just enters into on the shale shaker from the high position outflow. The vibrating screen has screen cloth with various screen meshes for replacement according to the requirement of liquid-solid separation, but the screen cloth on the same surface is only provided with the screen meshes with the same rule, so that the aim of liquid-solid separation is realized by arranging the same screen meshes, and the vibrating screen is also arranged aiming at that the rock debris crushed by the conventional drill bit is basically uniform particles. The rock debris particles carried by the drilling fluid are filtered out of free drilling fluid after passing through the vibrating screen, only the rock debris particles and the drilling fluid coated on the surfaces of the particles are vibrated to fall into the sand receiving basin from the vibrating screen, and then the rock debris particles and the drilling fluid are cleaned and prepared by geological logging personnel, which is a basic flow of geological logging sand-pumping work. However, with the popularization and application of new drilling fluid technology, such as PDC (polycrystalline diamond compact) micro-coring technology, the returned rock debris is no longer uniform fine particles, and meanwhile, along with a cylindrical rock core column, in such a case, the conventional rock debris fishing mode cannot meet the requirements of the new drilling technology, and the existing defects are gradually revealed, so that the deep homing of the rock debris is influenced.

In summary, the conventional rock debris fishing and screening device has the following disadvantages:

(1) the common sand receiving device is only suitable for rock debris particles with uniform particle size and similar shapes, but has great limitation on receiving the columnar micro core;

(2) the common sand receiving device can not carry out sequencing and separation on the sand receiving basin according to the rock debris return time sequence when screening and filtering the rock debris, only accumulation is carried out, and the rock debris is mixed in the sand receiving basin, so that the depth homing is not facilitated;

(3) the geological logging has no self-formed rock debris receiving device and has no selectivity in a special working environment;

(4) the rock debris is returned out without time sequence, and is stirred and cleaned without time sequence to be more mixed, so that the rock debris and the micro rock core column in the limited depth are not really identified;

(5) the rock debris fishing and cleaning procedures are discontinuous, organic unification is not realized, repeated labor is caused, the labor intensity is increased, and meanwhile, the efficient application of clear water resources is not facilitated;

(6) the variability and the adjustability of the conventional sand receiving basin are poor, and the combination property cannot be realized on the mechanical vibration;

(7) the equipment has high operation cost and is not beneficial to the conversion of new and old kinetic energy.
