The Research and Application of Ultra High Temperature Fracturing Technology for Glutenite Formations

open access: yesInternational Oil and Gas Conference and Exhibition in China, 2010
Abstract The temperature of some glutenite reservoirs of Shengli oil field located in the east of China reaches up to 180°C, and it would exceed 190°C in the subsequent exploring reservoirs, even close to 200°C. Nevertheless, neither the fracturing fluid system nor the down hole instruments can satisfy the fracturing technology demands ...

Fracability Evaluation Method of Tight Glutenite Reservoir

open access: yes, 2020
The tight glutenite reservoir has the characteristics of low permeability, uneven distribution of pore throat and strong heterogeneity, and the effect of fracturing stimulation is not obvious. Therefore, it is necessary to deeply study on the characteristics of tight glutenite reservoirs.

Influence of mechanical contrast between the matrix and gravel on fracture propagation of glutenite

Journal of Petroleum Science and Engineering, 2022
Abstract Glutenite is composed of gravel, matrix and their cementing surface in meso-scale. The fracture propagation in it is therefore different from the fine-grained rocks such as shale and sandstone. In order to study the influence of mechanical contrast between the matrix and gravel on fracture propagation and mechanical properties of glutenite ...

Characterization of meso-structure of glutenite reservoirs by ultrasonic characteristics and the velocity heterogeneity

Journal of Petroleum Science and Engineering, 2022
Abstract Different from fine-grained sedimentary reservoirs such as sandstone and shale, glutenite reservoir is rich in gravel. Its physical and mechanical properties are affected by gravel content and gravel size and are related to the cementation and support pattern between the matrix and gravel.

Experimental study on the mechanism of hydraulic fracture growth in a glutenite reservoir

Journal of Structural Geology, 2017
Abstract Glutenite reservoirs are frequently significantly heterogeneous because of their unique depositional environment. The presence of gravel in this type of formation complicates the growth path of hydraulic fracture (HF). In this study, laboratory fracturing experiments were conducted on six large natural glutenite specimens (300 mm × 300 mm ...

Influence of gravel on the propagation pattern of hydraulic fracture in the glutenite reservoir

Journal of Petroleum Science and Engineering, 2018
Abstract The clear mechanism of hydraulic fracture propagation in glutenite reservoirs with high heterogeneity is still not obtained, thus it is difficult to carry out the design of fracturing plan effectively. Based on the characteristics of the glutenite reservoirs, a coupled flow-stress-damage (FSD) model of hydraulic fracture propagation with ...

Study on Fracture Development in Glutenite Reservoir

56th U.S. Rock Mechanics/Geomechanics Symposium, 2022
ABSTRACT: Composed of gravel, matrix and the cementation surface, glutenite is different from fine-grained homogeneous reservoirs such as sandstone and shale in meso-structure. This unique structure inevitably leads to different fracture propagation characteristics.
