METHOD FOR OPERATIONAL FORECASTING OF HIGH-PRESSURE ZONES IN OIL AND GAS WELLS
The article analyzes methods and technologies for estimating anomalous reservoir pressure and predicting anomalous zones when drilling oil and gas wells. Methods for forecasting abnormal reservoir pressure, as well as signs (factors) used for these purposes are systematized and classified. The advantages of the developed methods are substantiated based on the dependence between the technical parameters of drilling. It is shown that the systems created on the basis of these methods make it possible to carry out the forecasting process without stopping drilling and in real time. The state of application of these systems in the drilling operations of SOCAR is investigated. A method included in this forecasting group is proposed. For the design of a working system based on the proposed method, the principle of forecasting, the algorithm of work and the conceptual architectural model are given. Information is given about experiments carried out by computer simulation to test the principle of the system (pp.29-36).
