Embodiment 1

[0024] The mixing ratio of oil field waste drilling mud solidification material is: mud: cement: sand: curing agent HA-1: mixing water = 10%: 10%: 70%: 1%: 9%, that is, 10kg: 10kg: 70kg: 1kg : 9kg. Mix mud, cement, sand and curing agent evenly, then add mixing water and stir for 10 minutes. For discharging, the mixed cured material is prepared into a sample block with a size of 10cm×10cm×10cm by pressing and molding, and it is cured naturally.

Embodiment 2

[0026] The mixing ratio of oil field waste drilling mud solidification material is: mud: cement: sand: curing agent HA-2: mixing water = 10%: 10%: 70%: 1%: 9%, that is, 10kg: 10kg: 70kg: 1kg : 9kg. Mix mud, cement, sand and curing agent evenly, then add mixing water and stir for 10 minutes. For discharging, the mixed cured material is prepared into a sample block with a size of 10cm×10cm×10cm by pressing and molding, and it is cured naturally.

Embodiment 3

[0028] The mixing ratio of oil field waste drilling mud solidification material is: mud: cement: sand: curing agent HA-1: mixing water = 20%: 20%: 59%: 1%: 0%, that is, 20kg: 20kg: 59kg: 1kg : 0kg. The solid materials were combined and stirred for 10 minutes. For discharging, the mixed cured material is prepared into a sample block with a size of 10cm×10cm×10cm by pressing and molding, and it is cured naturally.

Abstract

The invention discloses an oilfield waste drilling mud solidified material, which is characterized in that the solidified material is composed of oilfield waste drilling mud, cement, sand, a solidifying agent and mixing water, and the solidified material comprises the following components in percentage by mass: 10.0-50.0% of mud, 10.0-50.0% of cement, 50.0-90.0% of sand, 0.01-10.0% of a solidifying agent, and 0.0-10.0% of mixing water. The solidified material disclosed by the invention is high in intensity, and can meet the requirements of construction materials on strength; and extracts are low in toxicity, therefore, the solidified material is safe and environmentally friendly, and realizes the innocent treatment and resource recycling of oilfield waste drilling mud.

Description

technical field [0001] The invention relates to a treatment technology for waste drilling mud in oil fields, in particular to a solidification material for waste drilling mud in oil fields. Background technique [0002] Drilling mud can be called the "blood" of oilfield drilling. It mainly plays the role of carrying cuttings, stabilizing the well wall, balancing downhole formation pressure, cooling and lubricating the drill bit, etc. It is related to whether the drilling work can be carried out smoothly. Abandoned drilling mud is a multiphase stable colloid composed of clay, weighting materials, chemical additives, sewage, dirty oil, drilling cuttings, etc. , lead, etc.) have seriously polluted the environment. [0003] Thousands of wells are newly drilled every year in my country, and each well produces 200 cubic meters of waste mud, and the country produces millions of cubic meters of waste drilling mud every year. Traditional treatment methods include natural discharge,...
