Embodiment 1-1— comparative example 3-2
[0069] It aims to illustrate the treatment method for the first type of mud, as follows:
Embodiment 1-1
[0071] 5kg of the first type of mud was mixed with a gel breaker and a modifier, followed by gel breaking treatment and pressure filtration to obtain solid waste.
[0072] The drilling mud is the waste produced in the upper section of the first and second drilling of natural gas wells.
[0073] The gel breaker is polyaluminum chloride, and the consumption is 1.8% of the drilling mud;
[0074] The modifier is calcium sulfate, which is recorded as modifier A, and the dosage is 5% of the drilling mud mass.
Embodiment 1-2
[0076] The same treatment method as in Example 1-1 was adopted, except that the dosage of modifier was 7% of the drilling mud mass.

Abstract
The invention relates to resource utilization of natural gas drilling waste, and specifically discloses a roadbed filler using natural gas drilling waste as a raw material and a preparation method thereof. Through the classified control of drilling mud, chemical improvement, gel breaking treatment and incineration treatment are carried out for the mud in different well sections, and the improvement agent is screened, the incineration process is optimized, and the treated harmless solid waste is used to prepare roadbeds with building material properties Filling, the drilling waste has been fully utilized as a resource, which can produce good social and economic benefits.
Description
technical field [0001] The invention relates to resource utilization of natural gas drilling waste, in particular to a roadbed filler using natural gas drilling waste as a raw material and a preparation method thereof. Background technique [0002] With the development of the times and the progress of mankind, people consume more and more fossil energy, and the main components of fossil energy are oil and natural gas. Oil and natural gas are obtained mainly through drilling, but oil and gas exploration and drilling will produce a large amount of drilling waste, including drilling cuttings and drilling mud, which has become one of the main sources of pollution in the oil and gas industry. Due to engineering requirements, chemical additives are added to the natural gas drilling mud, and water, bentonite and other substances are mixed, resulting in high indicators such as petroleum hydrocarbons, chroma, and pH. In the past two years, the drilling team has used more and more wa...
