Method of utilizing well-drilling solid waste soil to prepare concrete or concrete blocks

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 [0001] The invention belongs to the field of environmental protection for oil and gas field gas development, and relates to a method for preparing concrete or concrete blocks by using drilling solid waste soil, so that the drilling solid waste soil can be utilized as a resource. Background technique [0002] When drilling oil and gas wells, it is necessary to continuously inject water into the wellbore, which will generate a large amount of magma waste liquid. The metal ions and organic substances in the waste liquid will pollute the environment, so solidification technology is used for treatment. The harmful components of the waste water are transformed, sealed and fixed, and then separated by solid and liquid, so that the content of harmful components in the separated wastewater can meet the discharge standards stipulated by environmental protection. The separated solid matter is called solid waste soil, which needs to be reprocessed. The composition of sol...
