The Tarim Oilfield Krasu tectonic zone is deeply burial, high temperature, low porosity and permeability, and constitutes the complex matrix-fracture dual media seepage channels. reservoir damage evaluation for such reservoirs is important for subsequent development. In this study, we firstly processed the fracture network in the reservoir core by controlled-pressure fracturing to improve the fracture tortuosity, and verified the reasonableness of this method by CT scanning and shape factor calculation. Then, based on the dual-media condition, we establish the water/oil-lock damage evaluation method, the stress-sensitive evaluation method, the fluid-sensitive evaluation method, and the in-well fluid damage evaluation method. Based on the above methods, the sensitivity of matrix-fracture dual-media reservoirs is moderately strong for water-oil locking, stress, and fluid salinity, moderately weak for liquid alkalinity, weakest for liquid flow rate. In-well fluid damage replacement experiments show that reservoir damage caused by first contact is the most important factor of reservoir damage during the whole process of drilling-completion-reconstruction. For deep tight reservoirs, fracturing fluid is easy to cause serious reservoir damage, and it is necessary to pay attention to reservoir protection during fracturing in low-yield blocks.

Paleozoic carbonate rock is the key field of oil-gas exploration in Tarim Basin. Fracture-cavity reservoirs are often developed in carbonate reservoirs in Tarim Oilfield, a large amount of oil and gas resources are dis-tributed in Paleozoic reservoirs with different burial depths and scales, accurately and quickly identifying these fracture-cavity reservoirs is Significant to the oil and gas exploration, development, and production of the Tarim Oilfield. With the continuous development of artificial intelligence technology, machine learning methods have been widely applied in various scenarios of oil and gas exploration and development, bringing new opportunities for the development of carbonate reservoir prediction technology. Based on drilling, logging and seismic data, this study comprehensively analyzes the structure, rock and physical properties of carbonate reservoirs in the study area, exploring the main controlling factors of carbonate reservoirs. On this basis, a sample set corresponding to the fracture-cavity reservoirs in the study area was constructed, by using machine learning methods, a prediction model for carbonate rock fracture-cavity reservoirs has been established, which can intelligently predict carbonate rock fracture and cave reservoirs in the research area.

Computerized Tomography (CT) technology has gained wide development in the field of petroleum geology due to its unique advantages in rapid, high-precision, non-destructive analysis, and three-dimensional imaging for microstructure analysis. This article reviews the research progress of CT scanning technology in the field of petroleum engineering in recent years and summarizes its applications in reservoir microstructure, rock and mineral properties, digital core simulation, and non-destructive analysis of rubber materials. Quantitative characterization information such as reservoir pore structure, mineral composition, particle size distribution, and fracture identification can be obtained through three-dimensional image analysis. By constructing digital cores, rock physical properties such as elasticity, permeability, electrical properties, and oil-water distribution can be further studied. In addition, CT scanning and imaging technology have also been gradually applied to defect analysis in rubber materials, providing new technical means for predicting their failure behavior. The construction of digital cores based on CT scanning technology has become a research hotspot in the petroleum field, providing technical support for the three-dimensional visualization and fine quantitative characterization of rock structures. In the future, achieving the integration of digital core data and constructing an application platform from core to reservoir, from micro to macro scales, is the development trend of high-precision CT scanning combined with computer technology. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

deploying horizontal well is one of the efficient methods to enhanced oil recovery. Maximum reservoir Contact (MrC) well, based on the horizontal well, which indicates the contacting area of wellbore and reservoir should be as large as possible to obtain the optimum exploration effects. The purpose of this paper is to build an assessment and optimization work-flow, which guides the well pattern improvement and well-type selection via a case study of the filed r in a Middle East Carbonate reservoir. Analyzing several field development index, like production performance, gas oil ratio, water cut, pressure, etc. in a pilot-scale well pattern both for the conventional horizontal wells and MrC wells using different injection schemes, including injection timing, injection volume, and injection components, via reservoir numerical simulation. The method using to evaluating reservoir exploration effect in this paper is numerical simulation, assuming different development strategies and well-type, via reservoir numerical simulator. Control-variate method as well as used in this study, which focus on keeping single factor analysis for the simulation. Comparing all the field development indexes among different cases while keeping other factors consistent, for example, exploring the influence from well types, which are MrC well and conventional horizontal well, two cases must be deployed the same injection schemes. Simulating different cases with analyzing the results, MrC wells obtain the better oil production generally compared with conventional horizontal wells. However, oil production performance is not the only index which is cared for in oil & gas industry, additionally, in terms of reservoir engineering, water cut, water breakthrough, gas breakthrough, gas oil ratio, oil steady production plateau, etc., while some economic indexes are extremely concerned by the experts and companies. Consequently, assessment of MrC wells effect should consider many factors from the perspe
