Abstract

The invention relates to a continuous mixing device and a continuous mixing method of a fracturing fluid. The continuous mixing device comprises a first mixing unit, a second mixing unit, a third compounding unit and a detecting unit which are connected in sequence. The continuous mixing method comprise the following steps: preparing a first mixed solution, adding an additive, preparing a second mixed solution, detecting, and discharging. The continuous mixing device and method provided by the invention can be used for mixing fracturing fluid rapidly and efficiently on site, thus the transportation cost can be lowered, the work efficiency can be improved, and the investment of labor force can be reduced. The continuous mixing device and method can be particularly popularized and applied to large-scale fracturing during shale gas development.

Description

Technical field [0001] The invention relates to the field of oil and gas field exploitation, in particular to a fracturing fluid continuous mixing equipment and a mixing method thereof. Background technique [0002] At present, there are three main methods of fracturing fluid mixing, namely traditional method, on-site liquid mixing method, and automatic liquid mixing method; [0003] In the traditional way, after the fracturing fluid is prepared by the mixing station, it is transported to the operation site by the transport tanker. This method has high fracturing transportation cost and is only suitable for near-well fracturing. [0004] The on-site liquid mixing method transports all kinds of chemical additives to the fracturing operation site. It relies on some simple equipment and on-site operators to realize liquid mixing. This method takes a long time to mix liquid and has a high labor intensity. The environment is poor, and the batch-to-batch operation process can easily lead ...
