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 a kind of method for preparing concrete or concrete segment with drilling well solid waste soil, make drilling well solid waste soil be able to recycling.
Background technology
When boring Oil/gas Well, will be constantly to water filling in pit shaft, can produce a large amount of magma waste liquids, metal ion and organism in waste liquid pollute the environment, therefore adopting curing technology is processed, this technology is carried out Zhuanization ﹑ Feng Bi ﹑ by solidifying agent by the objectionable constituent in waste liquid of drilling and is fixed, again through solid-liquid separation, Harmful ingredient content in waste water after making to separate reaches the emission standard of environmental regulations, isolated solid matter is called solid waste soil, need to process again, due to solid waste soil complicated component, water ratio is between 50%-70%, and moisture is comparatively stable, volatilization slowly, be difficult for fragmentation, bring very large difficulty to further recycling treatment.Existing disposal method has following two kinds: the one, and the landfill of digging pit, the 2nd, be used for making ground.Landfill is disposed need to take a large amount of soils; Dispose the inherent nature due to solid waste soil with making, make ground after the short period of time be not suitable for plant-growth, needing could raise crop after the 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 the oil sector problem demanding prompt solution.
On the other hand, in the construction investment of well site, the proportion maximum that construction investment accounts for, civil engineering comprises well site terrace, road and bank protection, due to well site in the wild, need to build road and highway connects, build the road and will expend a large amount of cement, building the well site bank protection will, with a large amount of barnacle pieces and cement, be also secondly terrace, also will use many cement, these three engineerings become the major portion of well site construction investment.If can gather materials on the spot, the solid waste land reform is caused to material of construction, replace cement, for well site, build, will the construction investment of decrease well site.The inorganics that contains 20% left and right due to solid waste soil, mainly silicon, iron, aluminium and calcium etc., therefore available solid waste soil is as the various building materials of raw material production, for example concrete and building block thereof, for well site bank protection, road, terrace, build, thereby realize the innoxious and recycling of drilling well solid waste soil, thoroughly solve solid waste soil handling problems.Not yet find at present with drilling well solid waste soil the report as the raw material production building materials.
Summary of the invention
The object of the present invention is to provide a kind of by the native method of concrete and building block thereof for preparing of drilling well solid waste, concrete prepared by the method and building block thereof are for well site bank protection, terrace, constructing road, thereby realize harmless treatment and the recycling of drilling well solid waste soil, thoroughly solve solid waste soil handling problems.
