| titleOfInvention | Deep shale gas development method |
| abstract | The invention discloses a deep shale gas development method, which comprises the following steps: evaluating the gas content of shale gas, and establishing a relationship between the analyzed gas content and a natural gas occurrence state; drilling three horizontal wells far away from a water layer and a fractured zone; step (3), mechanically segmenting the three horizontal wells, completing perforation in the segments, and then pretreating a shaft at the perforation by using acid liquor; step (4), performing large-scale fracturing by using the horizontal section; step (5), the type sequence of the injected fluid is medium-viscosity slickwater, low-viscosity acid liquid and medium-viscosity glue liquid, and after the proppant is conveyed in place, the high-energy material is excited to generate violent redox reaction in a mode of transmitting current to the stratum; and (6) after high-pressure mixed gas is mined from the gas recovery wells in the vertical well section and the horizontal well section, purifying and separating to obtain oil fuel substances, and further deeply processing according to product requirements. The application of the method makes economic and effective development of deep shale gas possible, is an important breakthrough in the technical field of shale gas methods, and has important significance in improving the development technical level and economic benefit of unconventional oil and gas reservoirs. |
