“…At present, the buried depth of the reservoir on the South Bank of Tahe River generally exceeds 7500 m, the formation temperature exceeds 160℃, the porosity is 0.4%-4.6%, and the permeability heterogeneity is strong. Deep carbonate reservoir has complex geological conditions and strong heterogeneity [1][2][3]. Based on the existing materials and previous research results, in this paper, through the fitting of fracture static pressure and fracture conductivity curve, the reservoir seepage characteristics are analyzed, the reservoir seepage characteristics were analyzed by using fracture static pressure fitting and fracture conductivity curve [4][5][6][7].…”

Since the deep and ultra-deep carbonate rocks in the Fuman oilfield have made continuous breakthroughs, the acidification and fracturing of the reservoir on the south bank of Tarim River have been faced with problems such as faster acidification and shorter effective acidification fracture length with the increased burial depth and formation temperature, which seriously restrict the effect of acidification and fracturing. At present, the Fuman oilfield has achieved remarkable results after acid fracturing construction. In this paper, the acid fracturing construction effects of multiple reservoir reconstruction Wells in Tahe Yueman, Fuyuan, Guole, and Manshen blocks are evaluated and classified by analyzing acid fracturing construction curves, using fracture static pressure fitting and fracture conductivity curve analysis. The characteristics and distribution law of carbonate reservoirs corresponding to different construction curves are studied, and various situations of artificial fractures communicating with natural fracture-cavity systems are analyzed. The research results can accurately guide the design optimization and development of acid pressure.

“…In addition, granite is hard to detect when buried thousands of metres underground, resulting in little attention to be paid during hydrocarbon exploration (Ye et al, 2020;Yi et al, 2021). However, with the development of global oil and gas exploration, breakthroughs have been made in granitic buried hills worldwide, and a few medium-to large-sized oil and gas fields have been discovered, such as the BachHo field in Vietnam, the Dongping gas field in China, the Penglai oil field in China, and the BC oilfield discovered in the Bongor Basin in Chad (Cuong and Warren, 2009;Dou et al, 2015;Chen et al, 2018;Guo et al, 2019;Li et al, 2021a;Dai et al, 2021). The exploration of buried-hill reservoirs in the basement has gradually become a new exploration field (Cuong and Warren, 2009;Dou et al, 2020;Ye et al, 2020).…”

Predicting the distribution of fractured and dissolved reservoirs in granitic buried hills is a prerequisite for finding high-quality hydrocarbon reservoirs and improving the success rate of exploration activities. Granitic buried-hill reservoirs in the Bongor Basin are characterized by strong heterogeneity and poor lateral continuity. Through the analysis of seismic, core, logging and dynamic production data, this study predicts the distribution of fractured reservoirs and fractured-cave reservoirs in the granitic buried hills in the BC Block of the Bongor Basin. In this study, we predict fractured reservoirs using coherence cubes and linearly enhanced attributes and identify fractured-cave reservoirs with single-frequency attribute bodies. Integrated predictions of fractured reservoirs and fractured-cave reservoirs are conducted using attribute fusion techniques. With these methods, good results have been achieved in reservoir prediction in BC buried hills. Furthermore, this study summarizes a set of granitic buried-hill reservoir prediction techniques for densely inverted rift basins in the Central African Rift System.
