Abstract

The invention relates to a bonding agent of baking-free bricks prepared from drilling well solid waste materials, which is applied to the field of treating petroleum drilling well solid waste materials into resources for preparing baking-free bricks. The bonding agent comprises the following ingredients in parts by weight: 3.3 to 8 of polyaluminium chloride, 6 to 25 of phosphogypsum, 10 to 26 of lime, 20 to 60 of fly ash and 4.4 to 12 of ferrous sulfate. A method for using drilling well solid waste materials for preparing the baking-free bricks comprises the following steps that: the baking-free bricks are prepared from the following ingredients in parts by weights: 10 to 22 of bonding agents of baking-free bricks prepared from drilling well solid waste materials, 30 to 55 of drilling well solid waste materials and 35 to 45 of crude aggregate; and the ingredients are uniformly mixed, are extruded and formed through a baking-free brick machine, and are maintained for 14 to 21 days to prepare the baking-free bricks. The invention has the advantages that the baking-free bricks can be prepared, and through the analysis via the sampling and the water soaking experiments on the baking-free bricks, all contaminant indexes reach the primary standard. Through the examination according to the standard JC422-1991, the detected items of the samples reach the requirements of the standard.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to resource treatment of drilling solid waste, and is a cement for making unburned bricks from drilling solid waste. Background technique [0002] At present, drilling solid waste mainly includes drilling waste mud and drilling cuttings. Drilling waste mud is a stable gel system with high water content, mainly composed of bentonite, barite and mud treatment agent, etc., and also mixed with a small amount of cuttings and drilling additives. Generally, the water content is about 90%, and bentonite accounts for about 5%. %. Drilling cuttings are mainly formation cuttings produced during the drilling process. [0003] Drilling solid waste unburned bricks is a technology researched on the comprehensive utilization technology of drilling solid waste. Due to the characteristics of low soil content and high barite powder content in drilling mud, appropriate amount of coarse ag...
