Description

Manual and electric combined type rock debris cleaning device for petroleum and natural gas exploration
Technical Field
The invention relates to the technical field of petroleum and natural gas exploration, in particular to a manual and electric combined type rock debris cleaning device for petroleum and natural gas exploration.
Background
Drilling fluid (in jargon called mud) refers to a fluid medium used in the drilling process. The drilling fluid may be a liquid or a gas, and therefore, the drilling fluid should be referred to exactly as a drilling fluid. During drilling, the circulating flushing medium used in the hole is also called drilling flushing fluid. The drilling fluid can be divided into clear water, slurry, clay-free phase flushing fluid, emulsion, foam, compressed air and the like according to the components. Clear water is the earliest drilling fluid used, does not need to be treated, is convenient to use, and is suitable for the areas with complete rock stratum and sufficient water sources. The mud is a widely used drilling fluid, and is mainly suitable for rock formations with unstable hole wall, such as loose, crack development, easy collapse and block falling, water swelling and peeling, and the like. The drilling fluid has the main functions of: (1) cleaning the bottom of the well, carrying rock debris; (2) cooling and lubricating the drill bit and drill string; (3) balancing the side pressure of the well wall rock; (4) balancing (controlling) formation pressure; (5) suspending cuttings and weighting agents; (6) sand and rock debris can be removed by sinking on the ground; (7) efficiently delivering hydraulic power; (8) bear part of the weight of the drill pipe and casing; (9) providing a plurality of data of the formation being drilled; (10) hydraulically breaking the rock.
The observation and analysis of rock cuttings are not separated from the work of geological logging, and the observation and analysis are also important bases for stratum evaluation and oil and gas resource evaluation. The rock scraps carried by the drilling fluid from the underground to the ground are all adhered with drilling fluid dirt, and the adhered dirt is required to be cleaned by clean water to restore the natural color of underground rock for observation and analysis of the rock scraps, so the rock scraps are an important job of geological logging sites. The conventional cleaning mode of rock debris is a basin and a stick; however, with the advent and continued penetration of fine and efficient exploration, this simple rock chip cleaning approach has not been suitable for a variety of new requirements, and a new chip cleaning device is needed.
In the process of logging rock scraps in a geological logging site, the rock scraps are cleaned by a simple and repeated working process, the basic method is kept unchanged for decades, namely, the rock scraps filtered by a vibrating screen are collected into a sand-bailing basin, and then are repeatedly stirred and cleaned by clear water by a stick, and if the stirring effect by the stick is poor, the rock scraps are rubbed by both hands until the rock scraps are cleaned. Under normal conditions, the rock debris drilled by the clear water is easy to clean, because the rock debris itself is already washed and cleaned in the upward return process; however, as the drilling depth increases, the performance of the drilling fluid needs to be continuously adjusted to meet the requirements of carrying cuttings, stabilizing the well wall, balancing the formation pressure and rapidly drilling, and the density and viscosity of the drilling fluid are firstly changed, and in order to meet the requirements, the density and viscosity of the drilling fluid tend to gradually increase as the well depth increases. The use of high density and high viscosity drilling fluid increases the difficulty of cleaning cuttings, as the high density and high viscosity increase the adhesion of the drilling fluid to the cuttings, which in turn results in increased difficulty of cleaning cuttings. Meanwhile, rock scraps with different properties can also cause different cleaning effects, compact rock scraps are easy to clean, and loose rock scraps are not easy to clean, because the loose rock scraps, such as shale with poor lithogenesis, are easy to hydrate when meeting water, so that the phenomenon that the rock scraps are washed more and less and the water quality is turbid is caused, and the repeated cleaning is needed until the rock scraps are cleaned. In addition to the above aspects, the reason that the rock debris is not easy to clean is that the cleaning tool and the cleaning method become another important aspect, and the fact that the cleaning is time-consuming and labor-consuming on the horizontal plane is not difficult to know from the practice of cleaning other objects, and the stirring effect of a stick is not added, so that various cleaning tools are appeared. In summary, conventional cuttings cleaning methods have a number of problems:
1. the cleaning mode of the cleaning tool, namely a basin and a stick is not scientific, and the cleaning efficiency is low;
2. the utilization rate of the washing clean water is low, so that the waste of water resources is caused;
3. poor cleaning efficiency, high operation labor intensity and no contribution to professional health protection;
4. the cleaning time is long, so that other operation progress is influenced, and the cross operation is influenced;
5. poor cleaning efficiency and high working efficiency, and influences the working quality;
6. the use of the basin and the stick is unreasonable, and is not suitable for the requirement of rapid drilling of medium-high frequency rock debris;
7. the tool is crude, and the standardization and standardization of the operation cannot be realized;
in a word, the rock debris cleaning mode of a basin and a stick can not meet the requirements of fine and efficient exploration, the labor intensity is high, the working time is long, the working efficiency is directly influenced, the consumption of clear water is large, the generated industrial wastewater is more wasted, and the environment is not protected. The key to solve the problem is to invent a high-efficiency rock debris cleaning device.
