Abstract
The invention relates to a method of utilizing well-drilling solid waste soil to prepare concrete or concrete blocks. According to the method, the well-drilling solid waste soil is used as the main raw material, dinas is used as the aggregate, and a glueing material is added, wherein the proportion of the well-drilling solid waste soil to the dinas to the glueing material is 60:30:10. The well-drilling solid waste soil, the dinas and the glueing material are mixed uniformly, the building material with the required strength can be obtained through moulding, and construction of a well-drilling well site revetment and a road is completed through the specific onsite technology. With adoption of the method, the onsite and timely utilization and harmless treatment of the well-drilling solid waste soil are realized, and better economic and social benefits are achieved.
Description
Technical field
The invention belongs to oil-gas field gas development environment protection field, relate to the method that a kind of drilling well solid waste soil prepares concrete or concrete segment, make drilling well solid waste soil be able to recycling.
Background technology
When boring Oil/gas Well, will constantly to water filling in pit shaft, a large amount of magma waste liquid can be produced, metal ion in waste liquid and organism pollute the environment, therefore adopt curing technology to process, objectionable constituent in waste liquid of drilling are carried out Zhuanization ﹑ Feng Bi ﹑ by solidifying agent and are fixed by this technology, again through solid-liquid separation, the Harmful ingredient content in the waste water after separation is made to reach the emission standard of environmental regulations, isolated solid matter is called solid waste soil, need to carry out reprocessing, due to solid waste soil complicated component, water ratio is between 50%-70%, and moisture is comparatively stable, volatilization slowly, not easily broken, bring very large difficulty to further recycling treatment.Existing disposal method has the following two kinds: one is landfill of digging pit, and two are used to make ground.Landfill stabilization needs to take a large amount of soils; Dispose the inherent nature due to solid waste soil with making, after making ground, the short period of time is not suitable for plant-growth, could raise crop after needing several years slaking.
In sum, find better outlet also at present solid waste soil, along with the rapid expansion of oil-gas field development scale, the handling problems of solid waste soil becomes increasingly conspicuous, and becomes oil sector problem demanding prompt solution.
On the other hand, in the construction investment of well site, the proportion that construction investment accounts for is maximum, and civil engineering comprises well site terrace, road and bank protection, due to well site in the wild, need to build road and highway is connected, build the road and want at substantial cement, building well site bank protection also with a large amount of barnacle block and cement, is secondly terrace, also use many cement, these three engineerings become the major portion of well site construction investment.If can gather materials on the spot, solid waste land reform is caused material of construction, replace cement, build for well site, will significantly reduce well site construction investment.Because solid waste soil contains the inorganics of about 20%, mainly silicon, iron, aluminium and calcium etc., therefore available solid waste soil is as the various building materials of raw material production, such as concrete and building block thereof, build for well site bank protection, road, terrace, thus realize the innoxious and recycling of drilling well solid waste soil, thoroughly solve solid waste soil handling problems.The current not yet discovery report of drilling well solid waste soil as raw material production building materials.
Summary of the invention
A kind of drilling well solid waste soil is the object of the present invention is to provide to prepare the method for concrete and building block thereof, concrete the method prepared and building block thereof are used for well site bank protection, terrace, constructing road, thus realize harmless treatment and the recycling of drilling well solid waste soil, thoroughly solve solid waste soil handling problems.
The object of the invention is to be achieved through the following technical solutions:
