A multi-stage game model for the false data injection attack from attacker’s perspective

The old oilfields in our factory have entered the period of high water cut, the target of fracturing has changed from the main layer to the non-main layer, and the main layers have been fractured again and again. We have difficulty in choosing proper layers because good layers are in high-water-cut and there are not enough emerge in poor layers. As the oil quality of new oilfields deteriorates gradually, the effect of the fracturing gets worse and the effective period is short. The fracturing potential is gradually reducing. In this paper, according to the characteristics of different oilfields, the focus of potential exploitation will be shifted to the high aquifer where the remaining oil is enriched and thin differential layer in old oilfields, The new oilfields will carry out fracturing reconstruction corresponding to oil and water wells to shorten the displacement distance. By constantly quantifying and optimizing the principle of well selection and layer selection, perfecting the adjustment mode, optimizing the fracturing technology and scale, and taking the “three development”, the fracturing potential is further released. The effect of the fracturing is guaranteed, and the development of the oilfield is improved.

“…Turpan-hami Basin is one of the three major sedimentary basins in Xinjiang. The basin is located in the eastern part of Xinjiang, extending in east-west direction, with a length of about 660km from east to west and a width of 60-130km from north to south, covering an area of about 53000km2 [2][3]. Located at the intersection of tarim plate Siberia plate and Kazakhstan plate.…”

Based on the study of geological conditions in Lianmuqin area, Turpan-Hami Basin, the structural characteristics of upper Shanshan Group, upper Sandili Dadun Formation, and the top of Kalaza Formation from the bottom to the bottom in the study area are analyzed. According to the structural morphological characteristics of the fault interpretation, comprehensive description of the size and length of the fault, the new fault interpretation. The interpretation process is more logical under the guidance of sedimentary and tectonic theories.

“…After analysis and checking the cementing quality chart, it was found that the cementing quality above the casing damaged stratum was poor, which led to the dislocation of the well in pi1-4JC mudstone interlayer. This mechanism of segmented growth of main boundary faults controls the migration of trough, and thus the distribution of effective hydrocarbon stoves in different periods [1].In recent years, with the deepening of research, more and more scholars have realized that most of the trunk boundary faults have a segmental growth mechanism [2].Generally speaking, the growth of a single fault is characterized by the increase in the displacement of the ascending dip fault and the increase in the length of the ascending strike fault [3]. As for the relationship between the displacement of the fault and the length of the fault, many scholars have conducted a large number of quantitative studies by observing the morphology of faults in the field and established a variety of growth models.…”
