Problems solved by technology
Adding multiple materials into the well through the same channel makes it difficult to control the batching time. At the same time, it is easy to mix and react before the water is mixed, which may cause the quality of the liquid to be unqualified. The hidden danger of spraying will cause personal injury from liquid splashing, material entering the well and environmental pollution; improper selection and installation of liquid dispensing device will cause low operating efficiency and high intensity, which will greatly affect the actual use effect and have certain adverse effects. Therefore, we propose a device and method for profile control and liquid distribution

The invention discloses a profile control liquid preparation device and method. The device comprises a clear water tank, a double-control water feeding pump, a multi-way jet device and a liquid preparation tank; the clear water tank is connected with the double-control water feeding pump; the double-control water feeding pump is connected with an inlet of the multi-way jet device; a plurality of pan flute type material inlets are formed in the upper portion of a negative pressure cavity of the multi-way jet device, and the multi-way jet device is connected with the liquid preparation tank through a tail-swinging and sliding rail type water distributor. Through the arrangement of the double-control water feeding pump, the clear water tank, the liquid preparation tank, a hose and the like, multi-channel immiscible completion of well entering material addition can be performed during combined use; no valve is arranged on an outlet pipeline, the tail-swinging and sliding rail type liquid feeding, proper specification of assembly type selection and installation and skid-mounted integration of the liquid preparation device are achieved, perfect connection of all stages of raw material adding, processing, conveying, using and the like is finally achieved, the real-time using effect is guaranteed, the liquid preparation process is simple, convenient, efficient, safe and environmentallyfriendly, and finally, the overall operation is more convenient.
Description
technical field [0001] The invention relates to the technical field of petroleum exploitation engineering, in particular to a device and method for profile control and liquid distribution. Background technique [0002] In the field of tertiary oil recovery in oilfields, profile control of water injection wells is an important method to improve oil recovery. Among them, adding various materials into the well to prepare a qualified profile control fluid is the main process link in the profile control measure, and the qualified liquid preparation is also a necessary condition to ensure the effect of the profile control measure. [0003] In the present invention, through the dual-control upper water pump, clear water tank, liquid distribution tank and hoses, etc., when used in combination, multi-channel non-mixing can be used to complete the addition of materials into the well; there is no valve on the outlet pipeline, and the swing tail slide rail type liquid inlet ;The compon...
