Abstract

The invention discloses a shale gas flowback fluid recovery treatment device and method. The device comprises a treatment pond, a feeding hopper is arranged at the top of the treatment pond, a filtering mechanism used for filtering shale gas flowback fluid is arranged on one side of the interior of the treatment pond, and a liquid conveying mechanism used for supplying diluent at intervals is arranged on the other side of the interior of the treatment pond; and a stirring mechanism used for mixing shale gas flowback fluid and diluent is arranged between the filtering mechanism and the liquid conveying mechanism, and a movable push plate is arranged at the bottom of a filter cartridge of the filtering mechanism. The invention further discloses a recovery treatment method corresponding to the device. According to the invention, the overall recovery treatment efficiency of the rock gas flowback fluid can be effectively improved, and the problems that the filter cartridge is easily blocked by filter residues and the diluent adding efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of recovery of shale gas flowback fluid, in particular to a recovery treatment device and method for shale gas flowback fluid. Background technique [0002] Shale gas refers to the unconventional natural gas deposited in organic-rich shale-based reservoir rock series, which is continuously generated biochemical origin gas, thermogenic gas or a mixture of the two, and can exist in natural fractures in a free state It exists in kerogen and clay particles in an adsorbed state, and a very small amount is stored in kerogen and asphaltene in a dissolved state. The proportion of free gas is generally 20% to 85%. The fracturing fluid is a fluid ore ( Gas, gas, oil, fresh water, brine, hot water, etc.) in the process of exploitation, in order to obtain high yield, the liquid used in the fracturing measures is borrowed from the liquid conduction force (such as hydraulic power, etc.), and the fracturing fluid is used t...
