Abstract

The invention discloses a method for improving the complexity of a fracturing exploitation crack system, a fracturing operation method and an underground heating device. The method for improving the complexity of the fracturing exploitation crack system comprises the steps that in the fracturing operation process, slick water in a horizontal shaft is heated after perforation is completed so as toincrease the complexity of cracks. According to the method disclosed by the invention, the complexity of the fracturing exploitation fracture system can be effectively improved, so that the long-termeffective flow conductivity of the normal-pressure shale gas reservoir fracture is improved, the effective period of a yield increase measure is prolonged, and the economic development benefit is improved.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation, in particular to a method and a construction process for increasing the complexity of a fracture system in fracturing exploitation. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale-dominated reservoir rock series. It is continuously generated biochemical gas, thermogenic gas or a mixture of both, and can exist in natural fractures in a free state. It exists in kerogen and clay particle surfaces in an adsorbed state, and a very small amount is stored in kerogen and asphaltenes in a dissolved state. [0003] With the depletion of conventional oil resources, the extraction of shale gas has gradually become the focus of today's oil and gas extraction. Shale gas resources include high pressure shale gas and normal pressure shale gas. The resources of normal-pressure shale gas are extremely huge. Once a commercial breakthrough is ma...
