Shale oil three-dimensional fracturing technology refers to the collaborative arrangement of fractures between layers and multiple wells in a plane, constructing a volume fracture network, and achieving the utilization of shale oil.

The design concept is to achieve the maximization of controlled reserves and effective transformation volume through three-dimensional well fracturing.

The technical key is the coupling design of three-dimensional well network and fracture network, optimization design of dense cutting and multiple clusters, control technology of three-dimensional pressure fracture network, and enhanced volume fracture network fracturing technology of horizontal wells. At the same time, it is equipped with online mixing of fracturing fluid, zipper/synchronous construction sequence optimization, and staggered peak production mode of well factories.

The three-dimensional fracturing technology of shale oil has technical advantages such as high degree of one-time utilization, large volume of fracture transformation, high fracturing efficiency, long stable production cycle, and low construction cost.

Through the overall fracturing production process and supporting integrated online mixed fracturing fluid system of the well factory mainly featuring “two well zipper fracturing and three well synchronous circulation fracturing”, multi well uninterrupted fracturing and relay production can be achieved. The well group can undergo 5-7 sections of fracturing per day, greatly improving the production efficiency. The shale oil three-dimensional fracturing technology system, which mainly focuses on three-dimensional cross layout and expansion of fractures, horizontal well reinforcement volume fracture network fracturing technology, online real-time adjustment technology of fracture network, and overall efficient fracturing production process of well factories, has become a key core technology for shale oil efficiency development.
