摘要： 根据随钻测录井实时地质导向和大斜度、水平井评价成图技术需求，针对传统绘图方法存在的弊端，提出了将测录井信息、井眼轨迹和地质模型进行二维分解的实时绘图方法。针对二维分解绘图方法绘图时空复杂度较高的问题，给出了不同事件驱动下的局部实时计算和拷屏重绘算法，控制了对CPU和内存的消耗、提高了绘图效率，消除了实时绘图的闪烁和卡顿现象。应用实例表明，二维分解实时绘图方法能够实现大尺度随钻测录井地质导向图形的流畅、无卡顿实时绘图，可提高大斜度、水平井储层模型评价的刻画精度和时效。

关键词: 随钻测录井, 地质导向, 巨尺寸, 二维综合成图, 高效实时画法

Abstract: According to the real time geo-steering and evaluation mapping requirements of logging while drilling in horizontal and high-angle wells, in view of the disadvantages of traditional borehole information displaying methods, a high efficient two-dimensional decomposition drawing method is proposed for real time logging information, well trajectory and strata. Aiming at the high time and space complexity of the two-dimensional decomposition drawing method, this paper provides local real time calculation and screen copy redrawing algorithms driven by different events, which control the consumption of CPU and memory, improve the drawing efficiency, and eliminate flicker and lag in real-time drawing. The application shows that the two-dimensional decomposition real-time drawing method can realize smooth, non-stuttering real time drawing of large-scale logging while drilling and mud logging geo-steering graphics, also it can improve the accuracy and timeliness of the evaluation of highly inclined and horizontal well reservoir models.

Key words: LWD (logging while drilling) and mud logging, geo-steering, huge size, two dimensional comprehensive graphics, efficient real time drawing method
