Description

Recycling method and system for base liquid thrown out by oil-based drilling cuttings
Technical Field
The invention belongs to the technical field of drilling waste treatment in the petroleum and natural gas industry, and particularly relates to a recycling method and a recycling system for base liquid thrown out of oil-based drilling cuttings.
Background
The oil-based drilling fluid is a drilling fluid system prepared by adding a matched treating agent by taking oil as a continuous phase, and the oil-based drilling fluid system is obviously superior to a water-based drilling fluid in the aspects of anti-erosion capacity, well wall stabilization, lubricity, reservoir protection and the like, so that the oil-based drilling fluid is widely applied to drilling operations of high-temperature and high-pressure deep wells, large-inclination directional wells, horizontal wells and various complex strata. With the increasing amount of oil-based mud that is returned from drilling, drilling operations generate a large amount of oil-based drill cuttings per day, and each well generates 400-; the oil content of the oil-based drilling cuttings is about 15-30%; meanwhile, the compound contains various toxic and harmful components such as phenolic compounds, heavy metals and the like, and is HW08 type hazardous waste specified in the national hazardous waste records. Thus, effective management and disposal of oil-based drill cuttings has the dual benefits of environmental protection and resource conservation.
Generally, at a drilling operation site, oil-based mud returned from a wellhead is separated into solid-phase oil-based drill cuttings (wet) and liquid-phase base fluid by a solid-liquid separation apparatus such as a shaker, a sand separator, a centrifuge, or the like. The liquid phase base fluid produced in the method is returned to a wellhead by a drilling crew for recycling, which is called as primary recycling, and the solid phase oil-based drilling cuttings (wet) generally contain 20-30% of base oil, so that further solid-liquid separation (drying) through a centrifugal drier is needed.
The oil-based drilling cuttings (wet) are separated into oil-based drilling cuttings (dry) and liquid phase throwing liquid by a centrifugal drier, wherein the oil-based drilling cuttings (dry) account for about 60-70%, and the liquid phase throwing liquid accounts for about 30-40%. The oil content of oil-based drilling cuttings (dry) is generally less than 10 percent, the oil-based drilling cuttings can be directly transported to a professional company for treatment, and the density of liquid phase throwing liquid is about 2.5-3.0g/cm due to the fact that the solid content is too high3The fluidity is poor, the oil can not be directly returned to a wellhead for recycling, and the oil needs to be purified, otherwise, the oil can be transported to a professional company for treatment.
70-95% of the throwing liquid is useful components, and the treatment of the throwing liquid as hazardous waste is a waste of resources, so that an advanced and practical technology and equipment are needed to fully filter solid particles contained in the throwing liquid and ensure that the solid particles meet the technical index requirement of recycling (the density is less than 1.0-1.2 g/cm)3) And secondary recycling of the liquid-phase base liquid is realized.
The existing treatment method of liquid-phase base liquid thrown out by oil-based drilling cuttings is mainly to use a centrifuge method to carry out solid-liquid separation, and the existing main problems are that:
1. the solid content of the liquid phase thrown out of the liquid is high (50-70 percent), the viscosity is high, the particle size of the contained solid is extremely small, the actual removal efficiency of a centrifugal machine on the small particles is not high, and the density after treatment is usually about 1.6-2.0g/cm3And, the recycling requirement cannot be met;
2. the high-speed centrifuge has a high-speed rotating part, so that the failure rate is high, and the energy consumption is high;
3. the operation and use are complex, and the field operation amount is large;
because the centrifuge can not guarantee the performance of the liquid phase (secondary base liquid) to meet the recycling requirement by solid-liquid separation, the liquid phase is thrown out and is directly boxed and transported outside to be treated in most occasions, the generation amount of hazardous wastes is increased, and the recyclable resources are wasted.
Therefore, a method and a system for recycling the base fluid thrown out of the oil-based drill cuttings are needed to solve the above technical problems.
