Embodiment 1

[0026] As the best implementation mode of the present invention, the present invention discloses a method for applying treated oil-based cuttings to inorganic stabilized road base, the steps are as follows:

[0027] (1) Using LRET technology and thermal analysis technology to process oil-based cuttings. The toxicity, flammability, corrosiveness, reactivity and acute toxicity of the leachate after treatment are all qualified and ready for use;

[0028] (2) Before the construction of the base layer, a comprehensive inspection of the base layer should be carried out. The surface of the base layer should be flat and solid, and it should have a specified road arch. Phenomenon;

[0029] (3) The mixture shall be fully mixed according to the content of gravel at 52%, sand at 12%, cement at 3-5%, and oil-based cuttings at 31-33%.

[0030] (4) Layer-by-layer filling: layer-by-layer compaction, the thickness of layered loose paving is less than 30cm, and the full-width and full-width f...

Embodiment 2

[0032] Refer to the attached Figure 1-3, this embodiment is a verification example, and the cost of cement-stabilized gravel materials mainly comes from the purchase and transportation costs of cement, gravel and sand. The mining of aggregates not only consumes manpower, material resources, and financial resources, but also has a certain impact on the ecological environment. In recent years, various places have attached great importance to environmental protection and restricted the mining of sand and gravel, which has also caused the continuous rise of raw material prices and increased construction costs. As a kind of industrial solid waste, oil-based cuttings can replace some sand and be used in inorganic binders, which will not only increase the treatment of oil-based cuttings, but also reduce construction costs. Different proportions of raw materials are blended to make the pavement structure meet the design requirements in terms of strength, which is technically reliabl...

Abstract

The invention discloses an application method of treated oil-based rock debris in an inorganic stable road base, which is characterized by comprising the following steps: (1), treating the oil-based rock debris by adopting a waste oil-based mud rock debris resource recovery technology LRET and a thermal analysis technology, and after the detection of various treated environmental indexes is qualified, standing by; (2), checking a subbase layer before a base layer is constructed, and removing pumice stones and sundries; (3), mixing the mixture according to the following mass ratio: 52% of gravel, 12% of sand, 3-5% of cement and 31-33% of oil-based rock debris; and (4), filling the mixture on the subbase layer in a layered manner and compacting the same to finally form the road base layer. The method can be used for harmless and resourceful treatment of the oil-based rock debris; the mixture can be used as an admixture of the road base layer, thus meeting the strength requirement of theroad base layer, and effectively reducing the cement consumption required in road construction and reducing the construction cost.

Description

technical field [0001] The invention relates to the technical field of resource utilization of pollutant oil-based cuttings produced in the process of petroleum exploitation, in particular to a method for applying treated oil-based cuttings to inorganically stabilized road bases. Background technique [0002] In the process of shale oil and gas development, after reaching the shale layer vertically, the drilling rig can travel horizontally along the shale layer for up to one or two kilometers to expand the gas production surface. In the process of horizontal travel, the well wall is easy to collapse, and a special drilling fluid-oil-based mud is required, so a mixture of oil-based mud, oil, water and underground cuttings, shale, etc. will be produced-oil-based cuttings . Oil-based mud is stable in performance, easy to maintain, and has good ability to stabilize the well wall and prevent collapse; it has good lubricity and can prevent drilling rigs from jamming to a limited ...
