[Abstract]:The AC gas cap reservoir in Xihu sag in the East China Sea is developed by using natural energy and producing gas cap and oil area simultaneously with the same set of well pattern. It is difficult to judge the condition of oil intruding into gas cap during dynamic tracking. Based on the principle of mass balance, a formula for calculating the volume of crude oil invading the gas cap is derived. The crude oil invasion indicator curve (crude oil invasion gas cap volume percentage-production time relationship curve) is constructed. The intersection point between the curve and the X axis is the starting time of the crude oil invasion gas cap, and the curve monotonously reflects the direction of fluid movement. The slope reflects the speed of movement. By using this method, the oil intrusion of AC gas cap reservoir is analyzed. The results show that when the recovery degree of oil is 4.3, the crude oil has quickly invaded the gas cap. Based on the sensitivity analysis of gas recovery rate in AC gas cap reservoir and the field test results, it is recognized that the ratio of production gas to oil can be reduced by reducing the oil recovery rate, thus achieving the purpose of reducing the gas recovery rate to restrain the crude oil from further rapidly invading the gas cap. The final site implementation effect is obvious. This method can be used for reference to guide the development of similar gas cap reservoirs.
