发明名称 Method for analyzing pressure buildup in low pumping rate wells
摘要 The pressure build-up of hydrocarbon wells is quickly measured allowing the well to be shut-in for a shorter length of time than previously possible to achieve the same results. After the well has been shut-in at the surface the rate of change of the level of the gas/liquid interface within the well bore is determined. The level change data are converted into pressure build-up data and flow rate data. Applying the convolution integral to the pressure build-up data gives the value of the equilibrated pressure of the well. The deconvoluted data can then be used to solve conventional algorithms to determine the state of the well bore and surrounding formation. The operator of the well can then make a variety of decisions, including continuing to produce from the well, stimulating the well, or abandoning the well.
