随着老井数量不断增多,地面大建筑物多,导致定向井比例越来越大,地下井网密集、井眼轨迹复杂,钻新井过程中很容易新井井眼轨迹与老井井眼轨迹相碰造成两口井同时报废,而且多套井网同时开采,井网密度大,井距小,常规钻井不能保证注采关系,我们必须要求钻定向井时加以条件限制(采取五段制)以及防碰设计,由于条件复杂利用以往的二维设计已经不能有效、合理的设计出最佳的井眼轨迹,为了有一个更清晰的井眼轨迹设计,我们在以往钻井公司二维设计的基础上完成三维可视化空间漫游设计。该项成果已经得到实际中,并且对矿区内的和谐发展、油田老区二次开发具有重要意义。
With the increase of the number of old wells and large buildings on the ground, the proportion of directional wells is getting larger and larger, the underground well patterns are dense and the well trajectories are complicated. During the process of drilling a new well, the new well trajectory and the old well trajectory The two wells were scrapped at the same time. In addition, multiple well patterns are simultaneously mined. The well density is large and the well spacing is small. Conventional drilling can not guarantee the relationship between injection and production. We must request that drilling be restricted to the well (adopt five-segment system) Touch design, due to the complex conditions of the use of the previous two-dimensional design has been unable to effectively and rationally design the best trajectory trajectory, in order to have a clearer well trajectory design, we 2D drilling company based on the previous design completed 3D visualization of space roaming design. This achievement has been actualized, and it is of great significance to the harmonious development in the mining area and the secondary development of old oilfields.
