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 dirt attached to the rock debris is cleaned by clear water to restore the natural color of underground rock for observation and analysis of the rock debris, so that the rock debris cleaning becomes an important work of a geological logging site.
The on-site cuttings washing operation of geological logging has long been a simple and tedious manual labor. 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, gradually by continuous collection, after a set detritus later time, the bailing personnel end the sand of concentrating in the bailing basin to a big water pitcher department and wash with discharging water to stir repeatedly with a random self-control 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 formed after underground rock is crushed, some rock debris are easy to clean and can meet the requirements after being washed for several times; sometimes, the cleaning is very difficult, and even the cleaning can be carried out for ten times or twenty times, so that the sand bailing personnel usually pay great physical strength in the whole cleaning process, and the wind and rain are unimpeded, and the main reason for the condition is the cleaning process. Therefore, the bailing and sand washing become heavy physical labor of geological bailing personnel, and are a miniature of field operation, namely 'low, old and bad'. Summarizing, there are several main problems:
firstly, the conventional rock debris cleaning mode occupies labor force and unit labor cost;
secondly, the conventional rock debris cleaning mode has high operation risk and has safety risk when crossing operation is carried out;
the working efficiency of the conventional rock debris cleaning mode is low, and the rock debris cleaning effect is poor;
the labor intensity of daily operation of the conventional rock debris cleaning mode is high, and the professional health protection of operators is not facilitated;
fifthly, sand washing sewage formed in the conventional rock debris cleaning mode is difficult to be intensively treated, cannot be recycled and pollutes the working environment;
sixthly, the continuity of the conventional rock debris cleaning mode operation is poor, which is not beneficial to improving the oil-gas exploration benefit;
and the automation of operation and on-site standardization cannot be realized under the conventional rock debris cleaning mode.
Therefore, a continuous, automatic and efficient sand washing operation device is urgently needed in an oil and gas exploration field.
