In the process of oil and gas field drilling,a large amount of solid waste will be produced,which contains lots of crude oil and chemical additives,and is very difficult forhandling.In order to effectively solve this problem and rationally use the resources,the study started from the non-curable rubber modified asphalt waterproofing coatings,by using thesolid waste of drilling to replace part of the inorganic fillers in non-curable rubber modifiedasphalt coatings.The feasibility of use of drilling solid waste in non-curable rubber modifiedasphalt waterproofing coatings was further explored by measuring the changes of coatingsperformance.The results showed that the solid waste could completely replace the inorganicfillers,effectively improve the softening point and ductility of the coatings,as well as the low temperature flexibility and the low temperature flexibility after thermal aging.Reduction of theviscosity of the coatings might be helpful for application and improved the creep and self-healing performance of the coatings. Due to excess performance,the formulation could be optimized to reduce the amount of Styrene-butadiene-styrene block copolymer(SBS) modifier,then reduce the cost of production.The study on use of the solid waste of oil and gasfields drilling in non-curable rubber modified asphalt waterproofing coatings not only solvedthe problem of difficult disposal of the solid waste and also improved the performance of non-curable rubber modified asphalt waterproofing coatings.
