To tackle the challenge of great depth, high pressure and temperature (HPHT), low permeability porosity, serious heterogeneity in deep oil/gas reservoirs, this paper proposed efficiency reservoir stimulation based on temporary plugging & diverting, which can realize multi-stage to improve stimulated rock volume (SRV) without mechanical isolating tools. A series degradable nanometer ester material with resistance strength has been developed. The feasibility method was tested by modeling...
Uniform acid distribution is a critical challenge and key factor for the successful acidizing of carbonate reservoirs. Previous experimental studies have shown that nanoparticles can enhance viscosity thermal resistance viscoelastic surfactant (VES) fracturing fluids. However, there has been limited research on effects wormhole propagation diversion performance VES acid. This paper establishes nanoparticle rheological model based rheology experiments, introduces porous medium temperature...
In the drilling process of Tarim Oilfield, a representative ultra-deep oil and gas reservoirs, there are many problems wellbore stability/instability caused by development large number micro-fractures. According to nano-plugging mechanism, rigid nano-SiO2 deformable nano-paraffin emulsion added fluid improve plugging rate. The effect nanomaterials on mechanical properties limestone in Karatal Formation was evaluated through triaxial experiment, it found that can have better under high...
Abstract Most of oil fields in China have stepped into the middle or later stage waterflooding life, and wells begin to appear above water. In conventional acid treatment, fluid always flows pore path with high water saturation firstly, broadens filled However, it can't stimulate as well that To solve this problem, especially heterogeneous formation, paper indicates a novel selective emulsified system, which viscosity will increase when meets decrease formation. The core flooding experiment...
Abstract Carbonate reservoirs are wildly distributed in China, and the reserve is very large. Bulk of big middle oil fields were discovered Sichuan Basin, BoHai Gulf Ordos Tarim Basin so on. The cumulative demonstrated geological reaches 1.62 billion ton, gas 1.42 trillion. Formations newly carbonate oil/gas have following features: deep buried (>5000m); serious heterogeneity; full pores, caves cracks; long well section. So, it's difficult for acid stimulation treatment. And treatment...
Abstract The paper is proposed to introduce nanoemulsion into the ultra-drilling completion fluid system improve plugging performance. pressure conduction method was used evaluate properties of tight sandstone, evaluation results showed that loss ultrafine drilling and with reduced 6.3 mL, difference between upstream downstream reaches 0.29 MPa Plugging Property double higher than without nanoemulsion, 2.96 times only nanoemulsion. nano-emulsion micro-nano solid particles in can seal layer...
Abstract In the process of temporary plugging and diverting fracturing horizontal wells, seating large-size balls on perforation is unstable efficiency irregular perforations low, so a smaller-size composite agent needed to improve efficiency. this study, based actual situation Changqing oilfield, three kinds materials with small particle sizes were used plug perforation. A simulated device different permeability was built by artificial cores, law pressure-bearing capacity inside studied....
Abstract During the formation of offshore carbonate reservoirs, interaction between magnesium-rich seawater and calcium sediments leads to reservoirs with heterogeneous mineral distributions, especially layers. The layers tend affect dissolution patterns in whole region a larger extent during acidizing, due large difference acid-rock reaction rates dolomite calcite. It is necessary study law influence rocks on avoid under- over-acid dissolution. Currently, there extensive research acid...
Abstract In the process of oil and gas development, perfect reservoir damage evaluation method is an important condition to realize economical efficient development reservoir. At present, great progress has been made in exploration tight gas. However, due characteristics low porosity, permeability water saturation sandstone reservoirs, conventional methods are not applicable it, no systematic formed yet. The reservoirs mainly include steady-state unsteady-state method. high temperature back...

Based on elasticity theory, we use numerical Galerkin finite element discretization method and implement Matlab code to simulate “stress shadow” distributions of mutual orthogonal fractures. The principal stress have the symmetry characteristic intersection (coordinate origin). relationships between shadow flow pressure ratio, pore pressure, fluid horizontal contract are analyzed, respectively. By these techniques variable displacement construction, changing viscosity fracturing fluid,...
