Description

Technical Field

[0001] The utility model belongs to the technical field of gas reservoir water lock release devices, and in particular relates to a solar intelligent water lock release control device. Background Art

[0002] Low-porosity and low-permeability reservoirs are characterized by small pore size, strong capillary force, and poor reservoir connectivity. With the continuous development of gas reservoirs, the invasion of foreign liquids leads to a continuous increase in the water saturation of the gas reservoirs, causing serious water lock problems, and ultimately leading to a reduction in the seepage capacity and production capacity of the reservoirs. In the field of natural gas extraction technology, the method of injecting water-locking agents is usually used to solve reservoir water lock damage and achieve efficient development of gas reservoirs. The water-locking construction process usually uses a plunger pump or a cement truck to inject a water-locking agent into the wellbore at one time. After the water-locking agent is pushed into the matrix reservoir by blocking the well, gas lift, venting, or direct production is used to remove formation water.

[0003] The existing technology of water lock removal process has many supporting equipments, involving multiple equipments and systems, high energy consumption, complex operation, low automation, and requires professional operators. Manual operation and high energy consumption increase the operation cost, which is particularly disadvantageous to gas well sites in remote mountainous areas. The lack of intelligent control equipment makes it difficult to accurately control the injection conditions of the reagents, which restricts the implementation effect of the plugging removal process.
