In order to develop the unused Chang 8 and Chang 9 reservoirs reasonably and efficiently, it is necessary to establish a set of reasonable well pattern system to accumulate experience and guide the efficient and reasonable development of other deep oil-bearing areas in Wuqi oilfield. The water flooding recovery factor of Reservoirs 8 and 9 is studied in the research area, along with the relevant parameters. Based on the relationship between different well spacing densities and recovery rates at various flow rates, well spacing densities of 6.8 wells per kilometer are determined for the study area. Based on the actual well pattern density of 9.2~18 Walls/km 2 in the developed Triassic oil fields in the west of Yanchang Oilfield, considering the connection of new and old well patterns, it is determined that the development well pattern density of Chang 8 and Chang 9 reservoirs should be 10~15/km 2 , and the well pattern density deployed at 300 m well spacing is basically suitable. On the basis of the analysis of the maximum principal stress and fracture orientation in the study area, the well pattern plan is deployed on the basis of the original 300 m~300 m square well pattern as far as possible to inherit the original pattern, using 300 × 300 square reverse nine-point well layout, and using the reverse nine-point injection method. The results of this study have a certain guiding value for the development of deep reservoir in this area and even the whole Wuqi oilfield.

Jiangsu Guanshan copper deposit, located in the Dawangshan Formation strata of Lishui volcanic basin in the Yanjiang depression zone on the northern edge of the lower Yangtze plate. III, VII and VIII ore veins occur in coarse andesite porphyry and hornblende coarse andesite porphyry in the Northwest Angle of Guanshan Copper Mine. In order to identify the distribution characteristics and co-exist of mineralized metal elements in three ore veins, it is based on mathematical statistical analysis of major ore-forming metal elements Cu, Au, Ag, Pb and Zn in three ore vein regions. The abundance of Cu in the trench sample (TC) (2050 ppm) is lower than that in the soil sample (BT) (2458 ppm) and the abundance of Cu in the borehole sample (ZK) (10,300 ppm); the abundance of Ag in BT (7.25 ppm) is lower than that in ZK (22.6 ppm); the abundance of Au in BT (0.269 ppm) is equivalent in ZK (0.252 ppm); Pb gradually enriched from BT (30.96 ppm) to ZK (2332 ppm); Zn has similar characteristics in TC (327 ppm) and ZK (346 ppm). In the analysis of the linear fitting of mineralized metal elements, Cu and Au have the highest determination coefficients (0.754) in the TC. The coefficient of determination for Cu and Ag in BT is 0.547. The determination coefficients for Cu, Pb, and Zn are all below 0.5, indicating a poor linear fit and no significant linear relationship. Based on the results from research and analysis of geological chronology and isotope geochemistry data of the deposit, it is indicated that the formation of this deposit oc-curred during the Early Cretaceous (K1) period. The ore-forming materials mainly originated from the upper mantle and lower crust. The mineralization took place under alkaline, medium to low-temperature conditions when magmatic hydrothermal fluids mixed with later atmospheric water. By analyzing the major ore-forming metal elements in internal veins III, VII, and VIII of the Guanshan Copper deposit, this study elucidated the spatial distribution characteristics and coexistence relationships of these elements. Additionally, a brief summary of the geological evolution process of the deposit was provided, offering references for future work in the Guanshan Copper deposit.

The Zhanhua Sag is a significant oil and gas exploration area in Jiyang Depression, Bohai Bay Basin. Lacustrine carbonate reservoirs of the upper fourth member of Shahejie Formation are the key exploration target in this sag. To further reveal the relationship between lithology, sedimentary microfacies and petrophysical parameters of lacustrine carbonate reservoir, in this paper, the upper fourth member of Shahejie Formation in Zhanhua Sag was taken as the target. The petro-logical characteristics, sedimentary microfsacies, petrophysical parameters and parameter sensitivity characteristics of lacustrine carbonate reservoirs are systematically characterized by comprehensive use of petrological, physical characterization and petrophysical testing data, and re-servoir petrophysical modeling is carried out. The results show that the lacustrine carbonate rocks in the upper fourth member of Shahejie Formation in the Zhanhua Sag are mainly limestone, the secondary is mixed rock, and the dolomite is less developed. It mainly develops lime-reef, lime-beach and lime-mud, including microfacies of reef core, reef front, channel among reefs, reef back, reef margin, beach core, beach margin and channel among beaches. In the case of dry and saturated samples, the velocity of P-wave, S-wave, bulk modulus, shear modulus, Young’s modulus and Poisson’s ratio of the beach core microfacies are higher than those of the beach margin mi-crofacies. The velocity of P-wave, S-wave and volume modulus of biogenic limestone is higher, the velocity of P-wave, S-wave and volume modulus of calcarenite is larger, and the Poisson’s ratio of limy dolomite, calcarenite, sandy limestone and micrite is lower. The intersection of the density, the ratio of P-wave velocity to S-wavevelocity and λ shows that fluid has no influence on the re-servoir lithology. The ratio of P-wave velocity to S-wave velocity and shear waves and λ has different sensitivity characteristics to distinguish sedimentary microfacies under different fluid conditions. The carbonate reservoir is predicted by Gassmann petrophysical model as a whole, but locally by DEM petrophysical model. The DEM petrophysical model is more accurate than the Gassmann model as a petrophysical model of heterogeneous reservoir with micro-fracture development
