Five schemes for remediation of oilfield soil pollution

The sources of oilfield soil pollution are mainly from the invasion of drilling mud during oil and gas exploration, extraction, transportation and storage. If the contaminated drilling mud cannot be disposed of in a timely, reasonable and effective manner, serious pollution of the soil around the oil field will occur. As the main source of pollution, drilling mud contains pollutants such as petroleum, heavy metals, organic chemicals, chloride ions and other pollutants that enter the soil without treatment, which will not only cause great harm to the soil, but also to the environment. The content of trace harmful elements in the soil exceeds the background value, and the content is too high due to excessive deposition, so it is called “soil heavy gold pollution”. Five schemes for remediation of oilfield soil pollution:

1) Oil sludge thermal desorption method oilfield soil pollution remediation plan:

The sludge thermal desorption method to remediate oilfield soil pollution is based on an integrated solution of solid-liquid separation. Through sorting equipment, the stones, weeds, tree roots and other sundries in the contaminated soil are separated; the proportions of oil and water are different. Physical properties: water, oil, and mud sand are fully stratified through water temperature and chemical stirring. The oil floats on the top layer according to the specific gravity. The water layer is in the middle, and the mud sand settles at the bottom layer. Finally, it passes through three-phase separation equipment or oil-water separation equipment. And mud-water separation equipment to achieve the purpose of three-phase separation of water, oil and mud.

2) Bio-method oilfield soil pollution remediation plan:

Bio-method oilfield soil pollution remediation program: Bioremediation is a method that uses biological growth and metabolism to degrade and transform organic matter. It has the characteristics of safety, reliability, and low repair costs. This soil pollution remediation plan includes: key processes, remediation preparations, supporting equipment and other core technologies.

3) Physical method of oilfield soil pollution remediation plan:

The physical method of oilfield soil pollution remediation program refers to pollution control technologies such as the soil method, incineration method, physical separation method, solution leaching method, solidification stabilization method, thermal desorption method and electrodynamic method based on physical methods.

4) United Technologies Oilfield Soil Pollution Remediation Plan:

The composition characteristics of oil and secondary metabolism determine the difficulty and complexity of oilfield soil pollution remediation. Therefore, a single technology cannot solve the pollution problem well, and it is necessary to consider the combined use of various treatment technologies.

5) Remediation plan for soil pollution of oilfield by leaching method:

The leaching method for remediation of oilfield soil pollution is an in-situ remediation method, which is very similar and close to the technical principles of “water flooding” and “polymer flooding”. The water from the injection well flows into the soil contaminated area of the oilfield, so that the oil contaminants in the oilfield soil are flushed into the area that can be pumped out by the groundwater well under the accumulation and driving of the water. The extracted petroleum-contaminated groundwater and flushing water are treated by surface facilities, and the rinsing water is recycled and reused. After the treated wastewater meets environmental protection requirements, it is discharged. When choosing an oilfield soil pollution remediation plan, different soil pollution remediation plans should also be selected for the oilfield soil contaminated by light oil and heavy oil.

Construction Mud Treatment-mud dehydration and drying equipment

Improper treatment of construction mud will pollute the environment, cause a large amount of soil erosion, block up rivers, affect water quality, and destroy municipal facilities. Early Construction Mud Treatment methods included landfilling, natural drying, etc. These more primitive methods have lower costs, but they cannot meet the increasing Construction Mud Treatment needs.

Therefore, the mud dehydration and drying treatment introduced in recent years has the following contents:

(1) Vacuum suction filtration method: the effect is poor, because the mud settles in the lower layer. When the vacuum is applied, the mud layer becomes denser and the water is difficult to suck out.

(2) Filter press method: The effect is good, but it is difficult to use on the construction site.

(3) The centrifugal dehydration and drying method is better than the above two methods. The centrifugal closed automatic and continuous operation does not require flocculation equipment. It is suitable for on-site construction environment and can fundamentally replace the current original and backward processing methods and improve processing efficiency. Reduce processing costs, protect the urban environment, and achieve civilized construction on site.

Drilling waste treatment status and technology

In the process of oil exploration and production, a large amount of waste will be left on the well site. In view of these harmful substances, how to adopt corresponding drilling waste treatment technology to minimize the harm caused by waste drilling fluid to the environment is a very important task for oil and gas field enterprises.

For a long time, most of the domestic oilfield drilling waste treatment is to directly solidify the waste liquid in the waste storage pool after the completion of the drilling and completion work. Due to the high water content in the total waste to be processed, this method consumes a lot of chemicals, has a high cost, and has an unsatisfactory effect, and it cannot completely eliminate the hidden danger of pollution.

With the requirements of local governments for environmental protection, the current domestic onshore oilfields are gradually paying attention to the harmless treatment of waste drilling fluid. Therefore, the treatment technology route with solid-liquid separation technology as the core has begun to be used in drilling waste treatment. This technology has changed from simple and rough direct solidification in the past to a process technology route combining chemical method, solid-liquid separation method and solidification method.
