高含水油田注水后油藏参数变化规律研究

This paper proposes an algorithms of total optimization based on the method of the orthogonal experiment to estimate directly wellbore and reservoir parameters in single layered,boundless reservoirs from the possible bound of the unknown parameters.

提出了一种确定油藏参数的全局性优化算法:根据正交试验法原理,在未知参数(渗透率、井储系数、表皮系数)的可能变化范围内,通过试算,快速寻找出最佳参数组合。

The advances in time-lapse seismic were mainly in 3-D prestack seismic simulation, data processing aimed at improvement of repeatability, and inversion of reservoir parameters.

从第 6 5届EAGE年会上有关四维地震的论文看 ,四维地震的进展主要表现在三维叠前地震模拟、提高重复性处理以及油藏参数反演等方面。

On the basis of analyzing the theory of forming method of the milling helical surface, this paper presents contact condition equation and calculates the slope angle of discrete points on end cuspidate of workpieces based on the accumulated chord length cubic parametric spline method and offers mathematical model of the cutter profile.

本文在深入研究成形法加工螺旋曲面的铣削理论的基础上,建立工件和刀具之间的接触条件,基于工件端截形为离散点数据的一般情况,应用累加弦长三次参数样条法,计算了工件端截形各离散点处的倾斜角,采用弧微分法建立了铣刀廓形的数学模型。
