为了进一步优化丛式井的设计,研究了丛式井平台井口和靶点的优选和分配问题。当井口分布呈多排多列且不均匀分布时,首先对井口和靶点进行直线或同心圆划分,再基于井口与靶点的连线在水平面上的投影两两不相交且水平位移平方和最小的方法(即不相交水平位移最小距离法),建立了不相交水平位移最小距离法计算模型,并编制了相应的分析计算软件。以吉林油田某丛式井组为例,利用编制的软件进行了井口和靶点的优选及分配,快速求出了最优分配结果。这表明采用不相交水平位移最小距离法可以快速求出最优的分配结果,可提高设计人员的工作效率。

In order to optimize the design of cluster wells further,the optimization and allocation of wellheads and targets on well pad had been investigated.If the wellhead in multiple rows and columns was uneven,first the wellheads and targets were divided with straight line or concentric circles,then based on the principle that the wellheads and the target connections do not intersect on horizontal projection and the minimum sum of horizontal displacement square called "disjoint and minimum distance method",the corresponding mathematical model and calculation software had been set up.Taking the cluster wells in Jilin Oilfield as example,the optimal wellhead-target distribution was worked out quickly by this calculation software,proving that the proposed method by the author could get the optimal wellhead-target distribution results fast,enhancing the efficiency of designers.
