Shale Shaker Working Efficiency Deterministic Factors

In the oil drilling process, The drilling fluids from the well can be transported to the mud control equipment by mud pump. As the first phase equipment of mud control, The drilling fluids shale shaker is one of the mud-water separation equipment and has the characteristics of the earliest separation, the fastest separation, economical and efficient. Shale shaker working efficiency determines the mud process efficiency of entire mud control system. so we must know what factors determine working efficiency of the drilling fluids shale shaker. There are three deterministic factors of shale shaker working efficiency.

The First Factor: Shale Shaker Mode of Vibration

There are three types vibration modes shale shaker. It is inear motion, circular motion, elliptic motion. If the center of gravity is at the vibrator, it can form the circular motion. If the center of gravity is above the vibrator, It can form circular motion. For the elliptic motion, the screen must have a slope in order to transportation of drill cuttings, but it can reduce the capacity of its screen. If the center of gravity is above and in front of the vibrator, The shaker can formed inear motion. The inear motion shale shaker has the constant speed of transportation of drill cuttings.

The Second Factor: The Amplitude and Frequency of Shale Shaker and vibrating motor

The capacity of shale shaker depends on three parameters: amplitude, mode of vibration, rotation speed of vibrating motor. The rotation speed of vibrating motor determines the vibration frequency of shale shaker. The higher of vibration frequency of shale shaker, the better of the solid phase screening. Generally, vibration frequency of the domestic high frequency shale shaker is approximately 2000 times /min.

The vibration mass and eccentricity determines amplitude of shale shaker. Amplitude is the vertical distance of the movement of shale shaker. Vibration strength is centrifugal acceleration of the vibrator. It reflects the mesh size of the force acting on the solid particles. In theory, The larger the vibration amplitude of shale shaker, the better of the removing effect. But after the vibration strength increases, The force of shale shaker is also increased. if so the expectancy shaker life can become shortened. Therefore we should considered comprehensively when designing and using.

The Third factor: Mesh and Material of Shale Shaker

Generally speaking, there are 2-4 shaker screens in shale shake. Drilling fluids must pass the first screen into a second screen, and so on. If the screen size is not suitable or be torn, the efficiency of solid-phase separation can decrease dramatically. If the screen can not be install reasonably, the screen will soon be worn or torn quickly. So when you select the screen, you must pay attention on the material of shaker sreen.

Structural Characteristics and Properties of Oil Sludge Sands in Oil Fields

The structural characteristics of oil mud sand in the oil field are particularly complex and diverse, making it very difficult to handle. It is generally composed of structures such as oil-in-water, water-in-oil and suspended solid impurities, and is an extremely stable mixture. The oil components in the sludge sand mainly contain saturated hydrocarbons and aromatic hydrocarbons, and the content of colloid and bitumen is less.

The composition of oil mud sand depends on the geological conditions of the major oil fields, the production technology and the process flow, and is also directly related to the variety of chemicals added, the quality of sewage, and sewage channels. Generally, the moisture content and salt content The amount of ingredients is high. Most of the sludge sands contain harmful substances such as arsenic, mercury, and salts. The characteristics of oily mud sand are mainly high crude oil content, some of which have oil content as high as 50%, high cohesion, and the main binding component of oily mud sand is also crude oil. Oil mud sand dispersed in water will be naturally divided into crude oil floating on the water surface and sand particles sinking to the bottom due to gravity, which mainly depends on the larger component density of oil mud sand. In water, the density of crude oil is lower than that of water.

There is also a big difference in the properties of the old oily sludge sand and the newly produced oily mud sand. The old oily mud sand has a long storage time, so there will be light components diffused during the long-term storage process, while some crude oil is due to the separation of seepage. The physical and chemical reactions of oil sludge will greatly change the properties of oil sludge, and therefore will slowly transform into a mixture of heavy oil, asphaltene, sand and soil.

Based on the above-mentioned structural characteristics, components and properties of oily sludge sand in the oil field, it is explained that the harmful components of oily sludge sand in the oil field are more and more complex, especially in the process of oil production, the addition of various chemicals will increase the toxic components of the oil sludge. These toxic components not only increase the difficulty of separation and purification of the oil sludge, but also more seriously, if the oil is directly discharged , Because the toxic substances are seriously exceeding the standard, the direct and arbitrary discharge will cause serious environmental pollution.
