Restoration and application of historical data of the Nangou block in Yanchang oilfield
摘要
Abstract
The historical data documented in the production process of the Nangou block in Yanchang oilfield mainly include initial monthly oil production,present daily oil production and cumulative oil production of part of the wells. There is a lack of water production,pressure and production time,and the producing degree of reserves and pressure field are unknown,thus bringing difficulty to later life development and modification. The cumulative oil production of each well is split to historical stages based on the production decline law of reservoirs developed by elastic energy and Alps decline model. Reservoir simulation is conducted to match parameters and to determine mass production and formation pressure by using quantitative oil production method. The validity of restored historical data has been verified by information wells. The restored historical data and remaining oil distribution based on numerical simulation are employed to optimize reservoir deployment plan and improve development efficiency.关键词
