Problems solved by technology

[0003] In foreign countries, because there are many kinds of polymer components in the flowback waste liquid of polymer flooding, it is difficult to treat them, so the oil production of polymer flooding is not carried out in foreign countries

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific examples.

[0014] On June 7, 2007, during the construction of the Liaohe Oilfield Shenyang Oil Production Plant Tongjing Road in the reconstruction project of the Guanbao-Xicaaogan Highway Baiyin Village Section of the Kerkang Oilfield in the Inner Mongolia Autonomous Region, the method of the present invention was laid on the upper base. The road grade is The specific construction technology of the oilfield patent road is as follows:

[0015] (1) On June 7, spread 30cm of wind-blown sandy soil in Kezuohou Banner, Liaohe Inner Mongolia Autonomous Region on the base.

[0016] Weigh polyacrylamide according to the ratio of sandy soil and polyacrylamide=100:10; weigh polyacrylamide according to the ratio of sandy soil+polyacrylamide to polyflooding waste liquid=100:3 (weight ratio) liquid, and add 1% water to the waste liquid to dilute evenly.

[0017] Crush the subgrade soil and spray th...

Abstract

The invention relates to a new use and a construction method of flow back waste liquid of the polymer flooding in road construction field. The waste liquid is always generated by the polymer flooding and has difficult treatment, but through reaction with porous earth, consolidating agent and the like, the poisonous substances can be sealed, which solves the environmental protection treatment of flow back waste liquid of the polymer flooding; the consolidated road bed is provided with high compression strength, which can satisfy roads construction requirements of each class, and more importantly strongly guarantees the application of the oil field polymer flooding process.

Description

Technical field: [0001] The invention relates to an application method of polymer flooding and flowback waste liquid, in particular to a method for applying polymer flooding and flowback waste liquid to the field of road construction so that the waste can be reused. Background technique: [0002] In the development and production of my country's petroleum industry, especially when polymer flooding technology is adopted in the later stage, oilfield exploration, development and production will produce a large amount of polymer flooding flowback waste liquid every year, because there are many kinds of polymer flooding waste liquid in polymer flooding Composition, in the case of a single environmental protection treatment, the investment is large, but the effect is not ideal, and it is easy to cause secondary pollution, which not only affects the environment, causes oil field environmental pollution, but also wastes resources and loses use value. Many developed countries now adop...
