Hydraulic permeation increasing process for large-dip-angle low-permeability coal seam

PendingCN113756775AIncrease concentrationEasy extractionSurveyFluid removalHydraulic fracturingWater leak
The invention relates to the technical field of coal seam hydraulic permeation enhancement, and discloses a hydraulic permeation increasing process for a large-dip-angle low-permeability coal seam which comprises the following steps: step (1), drilling: drilling a coal seam to form a fracturing hole; step (2), a hole sealing process is determined, placing two packers in each fracturing hole, wherein the two packers are distributed in a spaced mode, a plurality of branch holes communicated with the fracturing hole are formed in one side of the fracturing hole, the intersection point between the branch holes and the fracturing hole is a branch point, a fracturing pipe is inserted into the fracturing hole, and a screen pipe section of the fracturing pipe is put into the position of the branch hole needed to be fractured; step (3), fracturing parameter design, including pump injection pressure parameter and injection liquid quantity parameter design; step (4), type selection of fracturing equipment; and (5) fracturing: after the fracturing hole is sealed through a hole sealing material, after the hole sealing material is solidified for 12-48 h, connecting a pipeline and equipment, and starting a pump for water injection fracturing. The phenomenon of water leakage caused by poor hole sealing effect in the hydraulic fracturing process can be avoided.

Regenerated waterproof layer construction method

The invention relates to the technical field of waterproof construction, and particularly discloses a regenerated waterproof layer construction method. The regenerated waterproof layer construction method comprises the following steps that S1, a water leakage position of a roof plate is determined and marked; S2, drilling and sampling are carried out, the depth of a waterproof layer is determined, and the drilling depth is determined; S3, holes are formed in the periphery of the water leakage position at intervals by taking the water leakage position as the center, and embedded objects in the roof plate is kept away during drilling; S4, waterproof materials are injected into the holes in sequence, and after the single holes are filled with water, corks are plugged into the filled holes; and S5, when all the holes are filled with the waterproof materials, the holes are filled and leveled up with concrete mortar. The waterproof materials are prepared from resin components and hardening accelerators, and the weight ratio of the resin components to the hardening accelerators is 1 to (0.05-0.1); and the resin components are composed of the following components: 35%-45% of petroleum resin, 6%-10% of acrylic resin and the balance of deionized water. According to the regenerated waterproof layer construction method, the waterproof layer damage can be effectively repaired, and the repairing efficiency is high.

Water collecting and spraying equipment for garden with small area

The invention provides water collecting and spraying equipment for a garden with a small area. Water is injected into a sucker through a pressing base; when the water in the sucker is sufficient, thewater leaks out through connecting belts, so that the water is sprayed on flowers through the connecting belts; when the amount of the water in the sucker is gradually decreased, the pressing base isblocked and pressed downward by a finger, so that the pressure of the interior of the sucker is gradually reduced, the water is sprayed through the connecting belts, fine holes in the connecting beltsmake the water sprayed more uniformly, and waste of the water is avoided.
