The invention relates to the technical field of
oil field fracturing and acidizing, particularly to a method for enhancing network volume fracturing effects of complex
hydrocarbon reservoirs. The method comprises the following steps of, firstly,
flat network modification, secondly, tackifying
branch fracture formation, thirdly, artificial fracture formation, fourthly, three-dimensional network modification, fifthly, artificial fracture sand filling, and lastly, displacement liquid filling, well shutting, well opening for drainage, and reservoir yield measurement. The method for enhancing the network volume fracturing effects of the complex
hydrocarbon reservoirs can maximize network volume fracturing modification around perforation points and to the maximum degree improve the durability ofmodification volume and flow
conductivity of fractures and prolong the post-fracturing stable production period, save
working fluid by 10-30%. Meanwhile, the method for enhancing the network volume fracturing effects of the complex
hydrocarbon reservoirs increases common planar small-thickness irregular ellipsoidal network volume fracturing effects to high-three-dimensional-degree network volumefracturing effects, is simple and practical in field construction, reduces consumption of slick water and is applicable to ready-to-use integrated construction.
