Advanced Technology for Oil and Nature Gas Exploration

Topic Information

Dear Colleagues,

The unprecedented level of rapid globalization has accelerated the need for petroleum and gas. Without advanced petroleum and gas exploration technology, it becomes more difficult to recover sufficient amounts of oil and gas. Low-to-medium maturity shale oil is a promising alternative energy, and the in-situ conversion method, via a catalyst or high-temperature fluid, has been proven to be one of the most promising measures. Novel nanomaterials are also urgently needed. In addition, drilling causes serious formation damage without suitable pretreatment. To maintain stable oil and gas production, efficient formation protection measures must be taken; in this area, novel technology and agents are important safeguards.

The deterioration of rocks’ mechanical properties during the late stage of water injection development significantly reduces the rock-breaking efficiency of PDC bits. In this study, X-ray diffraction mineral composition analysis and triaxial compression mechanics tests were used to systematically characterize the weakening mechanism of water injection on reservoir rocks. Based on an analysis of mechanical experimental characteristics, this study proposes a multi-scale collaborative optimization method: establish a single tooth–rock interaction model at the micro-scale through finite element simulation to optimize geometric cutting parameters; at the macro scale, adopt a differential bit design scheme. By comparing and analyzing the rock-breaking energy consumption characteristics of four-blade and five-blade bits, the most efficient rock-breaking configuration can be optimized. Based on Fluent simulation on the flow field scale, the nozzle configuration can be optimized to improve the bottom hole flow field. The research results provide important theoretical guidance and technical support for the personalized design of drill bits in the later stage of water injection development. Full article

The Lower Cretaceous Jiufotang Formation in the Fuxin Basin contains a proven petroleum system. However, its southern part remains underexplored due to limited drilling and fragmentary sedimentary studies. To address this issue, we conducted detailed sedimentological logging of the two typical outcrop sections, Pijiagou and Tanjiagou. Field observations, petrographic data, and grain-size analysis were integrated to decipher hydrodynamic conditions, calibrate microfacies associations, and reconstruct the sedimentary evolution through facies stacking pattern analysis. The results show that the Jiufotang Formation predominantly consists of calcareous fine-grained clastic rocks, with poorly sorted sandstones indicative of low-energy conditions. Sediment transport mechanisms include both traction and turbidity currents, with suspension being predominant. The succession records a depositional transition from fan-delta to lacustrine environments. Two subfacies, fan-delta front and shore-shallow lacustrine, were identified and subdivided into seven microfacies: subaqueous distributary channels, interdistributary bays, subaqueous levees, mouth bars, muddy shoals, sandy shoals, and carbonate shoals. The sedimentary evolution reflects an initial lacustrine transgression followed by regression, interrupted by multiple lacustrine-level fluctuations. The alternating depositional pattern of lacustrine and deltaic facies has formed complete source-reservoir-seal assemblages in the Jiufotang Formation in the study area, making it a potential favorable target for hydrocarbon accumulation.

The intrinsic mechanism linking surface deformation to casing damage due to layer slippage remains unclear. Moreover, no method currently exists for calculating the slip deformation field of horizontal structural weakness planes from surface deformation. Therefore, we present a novel approach to infer formation pore pressure using surface deformation data based on Fourier transform and Wiener filtering. A forward modeling method is used to determine slippage along horizontal structural weakness planes, and a theoretical method is developed to derive slippage from observed surface deformation. We also apply a critical slippage threshold for casing damage to delineate risk zones via a maximum slip calculation model using data from the Daqing Oilfield in China. Our results reveal a strong correlation between casing damage occurrence and identified risk areas; within 6 months, 12 new casing damage wells appeared in high-risk areas, compared with 5 in low-risk zones. This method provides a scientific basis for the formulation of prevention schemes against shear casing damage in oilfields with weak horizontal structures. Full article
