Description
Technical Field

Background
Drilling fluid (known as mud) refers to the fluid medium used in the drilling process. The drilling fluid may be a liquid or a gas, and therefore, the drilling fluid shall be referred to as exactly a drilling fluid. In the drilling process, a circulating flushing medium, also called borehole flushing fluid, is used in the hole. The drilling fluid can be divided into clear water, slurry, clay-phase-free flushing fluid, emulsion, foam, compressed air and the like according to the composition. The clean water is the earliest drilling fluid, does not need to be treated, is convenient to use and is suitable for regions with complete rock stratums and sufficient water sources. The mud is widely used drilling fluid and is mainly suitable for unstable rock formations of hole walls, such as loose rock formations, fracture development, easy collapse and block falling, water swelling and peeling, and the like. The drilling fluid has the main functions of: (1) cleaning the well bottom and carrying debris; (2) cooling and lubricating the drill bit and drill string; (3) balancing the rock lateral pressure of the well wall; (4) balancing (controlling) formation pressure; (5) suspended rock debris and weighting agents; (6) sand and rock debris can be removed on the ground; (7) the hydraulic power is effectively transmitted; (8) bearing partial gravity of the drill pipe and the casing; (9) providing a large amount of data of the drilled stratum; (10) and (4) hydraulically breaking the rock.
In the exploration of oil and gas resources, the main body work of geological logging is the observation and analysis of rock cuttings, which is also an important foundation for formation evaluation and oil and gas resource evaluation. The rock debris is broken by the impact of a drill bit in the well, the drilling fluid carries the rock debris returning to the ground to be attached with the dirt of the drilling fluid, and the attached dirt is cleaned by clear water to restore the natural color of underground rock when the rock debris is observed and analyzed, so that the rock debris cleaning becomes an important work of a geological logging site. The conventional way of cleaning rock debris is a basin and a stick. However, with the development and the continuous deepening of fine and efficient exploration, the simple rock debris cleaning method is no longer suitable for various new technical requirements, and cannot catch up with the automation process of field operation, so that a novel rock debris cleaning device is urgently needed to replace the traditional rock debris cleaning operation mode.
Sand washing operations for geological logging have long been a simple and tedious manual task. The bailing personnel place a sand receiving basin in the low reaches of drilling fluid shale shaker, and the detritus shakes from the shale shaker and falls to in the bailing basin, and after a set detritus later arrive the time, the bailing personnel end the sand that concentrates in the bailing basin and a big water pitcher department and drain and wash to stir repeatedly with a puddler. After the water is dirty, the sand bailer needs to pour the water, then clean water is added for cleaning, the operation is repeated until the rock debris is cleaned, and then the rock debris is placed at a specified position for next step operation. For the rock debris, some rock debris are easy to clean, and the rock debris can meet the requirements after being washed for several times; some rock debris are not easy to clean, even the rock debris can be cleaned after being washed for ten times or twenty times, and the sand bailing personnel pay great physical strength in the whole cleaning process, and the cleaning process is free from wind and rain. Therefore, the bailing and sand washing become heavy physical labor of geological bailing personnel, and the following problems exist in summary:
firstly, the labor is occupied, and the labor cost is increased;
secondly, the operation risk is high, and the safety of cross operation is low;
thirdly, the working efficiency is low, and the rock debris cleaning effect is poor;
high labor intensity and is not beneficial to occupational health protection;
fifthly, the sand washing sewage is difficult to be treated in a centralized way and cannot be recycled, thus polluting the environment;
sixthly, the sand washing operation has poor continuity and is not beneficial to protecting the oil gas exploration benefit;
and the automation of the rock debris cleaning operation cannot be realized, and the scientific and standard requirements cannot be met.
Therefore, an efficient sand washing operation device is urgently needed in an oil and gas exploration field.
