Summer 40 Fault Block Oil Reservoir Geology

Drilling has been the use of new geological information, located in Shandong Province went Yuhuangmiao, River oilfield business three block area east of 40 summer geological analysis, In the first phase of the re-structure based on the map of speed traps for the further study of igneous, In view of the main aims (the sand on the bottom of reverse order of sand, sand the top two under the sand). 40 regions in summer re-interpretation of seismic data processing, map and revised some correlation, layers division. produced a map of the results, the structure study, the sedimentary facies and reservoir, reservoir and other aspects of the comprehensive study, calculation of reserves.There are three obvious areas in the formation of magmatic activity concentrated period, the first three of the late sand to shallow intrusive as the main form; Second, sand—sand late on a two-to be divided into a large number of volcanic eruptions; Third, the three early Museum, The ground covered by the overflow magma (basalt) features. Depositional environment for the summer 40 wells belonging to the whole environment of deposition of sedimentary environment Huimin depression, With the formation of depression, evolution, the ancient lake movements, Es4 deposition from all strata to the confluence with the group. Well in Summer 40 Huimin depression sedimentary environment constraints, its own characteristics. The changes include microfacies and dynamic emerging igneous rocks. Based on the analysis of sedimentary facies in reference to Wells River region, especially near the stratigraphic correlation, Under accumulation of vertical and lateral accretion theory, first identified the standard level and stability of the region marked contrast, According to the sedimentary characteristics of the region Well, a reasonable correlation, According to data logging and log features comprehensive set of igneous rock layer, excluding stratigraphic thickness of the igneous interference Wells adjacent to the work area and the system, accurate comparison. Well at 40 Summer River Oilfield Construction on the three business areas eastward extension of the fault zone. three major fault zones in the north and transfer belt gradually disappeared, the area is very developed structure igneous both intrusive rocks. Rock also eruption, the initial phase of understanding, has many causes, there are multiple solutions has been made structures. Well summer 40 main purpose of the reservoir layer dye layer of fine gray sandstone, siltstone, shale, gravel sand, gray sandstone. the performance of a light brown oil. Reservoir comprehensive study to the source rocks that cover and reservoirs, and migration and accumulation of oil and gas, oil and igneous rocks, reservoir evaluation for the study. Block oil reserves calculated by analysis and evaluation.
