井间地层压力分布预测方法及应用

Interwell Strata Pressure Distribution Prediction Methods and the Application

油藏的井间地层压力分布是油田开发过程中重要的开发指标之一。对动态预测、储量计算来说是一个非常重要的参数,如何获得准确的井间地层压力分布数据就显得尤为重要。以往的地层压力分布计算方法具有一定的局限性,无法准确的利用少数井来预测井与井之间的地层压力分布。在理论模型的研究基础之上编制了地层压力分布预测的计算机程序语言和计算模块,根据建立的压力场分布预测技术,预测并绘制了二区七断块历年压力场分布图。预测结果与实际生产一致,说明该地层压力预测技术是可行的,为油田的开发提供了较准确的参数依据。

The interwell strata pressure distribution of reservoir is one of the important development indexes in the process of the oil field development. Dynamic prediction and reserves calculation are very important parameters, so it is particularly important that how to get accurate strata pressure distribution data. Due to the inaccuracy of pre- vious reservoir pressure distribution calculation method , cant use a few wells to predict the interwell strata pressure distribution. This method based on the research of the theory model, developed computer programming language and calculation module of reservoir pressure distribution forecasting. Based on the established pressure field distri- bution prediction technology, predict and draw pressure field distribution map of 7 fault block of 2 area in the recent few years. Prediction results and the practical production are consistent. This method is feasible. Basis for the de-velopment of oil filed correctly is provided.
