Abstract

The invention discloses a method for determining real-time steering fracturing parameters based on a composite temporary plugging system, and relates to the technical field of unconventional shale oiland gas reservoir reconstruction. The method for determining the real-time steering fracturing parameters comprises the following steps that temporary plugging of perforating holes and fractures of different scales is achieved by using the composite temporary plugging system including a soluble temporary plugging ball and temporary plugging particles, meanwhile, integrating of the data analysis of geological parameters, construction pressure, and micro-seismic real-time monitoring is conducted to form the real-time optimization of the adding amount, adding timing and adding frequency of composite temporary plugging materials, the uniform transformation of the horizontal section is achieved, and the complexity of a fracture network is improved.

Description

technical field

[0001] The invention relates to the technical field of unconventional shale oil and gas reservoir stimulation, and more specifically relates to a method for determining real-time steering fracturing parameters based on a composite temporary plugging system. Background technique

[0002] The successful commercial development of unconventional shale oil and gas in North America has transformed the world's energy landscape. National shale gas demonstration areas such as Changning-Weiyuan, Zhaotong, and Fuling have been established in China. CNPC has listed Dagang Oilfield, Xinjiang Oilfield, Turpan-Hami Oilfield and Changqing Oilfield as important demonstration areas for shale oil development. The ultra-low porosity and ultra-low permeability of unconventional shale reservoirs, horizontal wells and volume fracturing technologies have boosted the commercial development of such reservoirs. With the advancement of horizontal well drilling technology, the effective...
