Device capable of monitoring fracturing flow-back fluid accident leakage soil pollution

Abstract

Aiming at environmental pollution and soil structure damage caused by the fact that a large amount of flow-back fluid generated in the fracturing exploitation process of shale gas is discharged to the earth surface, the invention provides the device capable of monitoring the fracturing flow-back fluid accident leakage soil pollution. The device mainly comprises a fracturing flow-back fluid geologic model, a pressure gauge, a pressure pump, a fluid meter, a ground penetrating radar, a replenishment fluid pool and the like. The device can simulate flow-back fluid leakage accidents under the conditions of different pressures, different fluid metering and different leakage depths, monitoring of the time-space distribution range of fracturing flow-back fluid accident leakage can be achieved through the ground penetrating radar, and the device has an important guiding effect on field flow-back fluid pollution environment treatment and solving.

Description

Technical field[0001]The present invention relates to the field of returning liquid contamination environment after fracturing construction during shale gas mining, and in particular, there is a monitored fracturing returning discharge accident leakage soil contamination device.Background technique[0002]The oil and gas is extremely important, and my country's oil and gas exploration has experienced a decades of exploration and development, which basically seizes the exploration of conventional oil and gas. As the degree of exploration is continuous, exploration objects are increasingly complex, especially for exploration and development of non-regular oily and gas pages. Low penetration and special osmotic shale gas reserves are increasingly used in my country's unhappy oil and gas reserves, economical, effective exploration and development to the sustainable development of my country's oil and gas industry. However, the natural production capacity of low permeability lendo gas is p...
