Description

救援井轨迹调整方法及装置 技术领域
本申请涉及钻井技术领域，尤指一种救援井轨迹调整方法及装置。
背景技术
随着高压井喷失控井救援、储气库复杂老井封堵、老油区套返弃井报废，环保井治理等生产需求逐渐暴露，也从有源磁导向钻井技术向无源磁导向钻井技术进行迭代升级。
目前，对于井间相对位置探测的研究较少，一般采用WELLspot导向工具来实现井间的精确连通，但其核心技术保密。现有技术中的CN202210600439通过重合点、三角导航和三维变二维方式进行轨迹校正，CN202111181808通过井眼轨迹反演方式进行轨迹校正，但是两种方案的校正结果滞后，未充分考虑不同仪器之间的相对误差，特别在定向井或水平井实际操作过程中仍面临失效风险。常规的测量方法，即磁导向与陀螺的分开测量方式虽然是在同一深度条件下对目标进行定位，但延长了测量作业的总体时间，增加了作业成本，并且每次测量的深度定位也存在误差，这增加定位目标的累积误差。

具体的，上述救援井轨迹调整方法可通过陀螺测量设备采集救援井在预设井深下不同测点的井斜角和方位角数据；根据井斜角和方位角数据获得角度参数；以及，通过磁导向测量设备根据所述空间坐标数据采集救援井与当前井的相对位置。在实际工作中，其调整流程可参考图1B所示，具体如下：
步骤S1：基于陀螺测量仪器测得救援井在预设井深下的井斜角和方位角；
步骤S2：递推计算得到预设井深下救援井的空间坐标；
步骤S3：基于磁导向测量系统测得所述预设井深下救援井与老井的相对位置；
步骤S4：将目标井轨迹校准到救援井基准上；
步骤S5：反推计算得到轨迹平稳段救援井与目标井的井斜角和方位角的角差；
步骤S6：按照校准后的井斜角和方位角给出轨迹调整的预测值。
各步骤的具体实现方式将在后续实施例中详细说明，在此就不再一一详述。
在步骤S1中，主要是基于陀螺测量仪器测得救援井在预设井深下的井斜角αn和方位角
其后，执行步骤S2，递推计算得到预设井深下救援井的空间坐标。具体的，请参考图2所示，在本申请一实施例中，根据所述角度参数计算获得预设井深下救援井的空间坐标数据包含：
S201根据所述井斜角和方位角数据通过递推计算获得不同测点的空间坐标；
S202根据所述空间坐标获得预设井深下救援井的空间坐标数据。
在实际工作中，基于测斜仪测得救援井在不同测深l处的井斜角α和方位角对于足够小的间隔，第li处的空间坐标可以通过第li-1的空间坐标递推积分而来，公式为：
递推至井口即可得救援井所有测点的空间坐标(x,y,z)，从而得到预设井深下救援井的空间坐标为(xn,yn,zn)。
接着进行步骤S3，基于磁导向测量系统测得所述预设井深下救援井与老井的相对位置，包括最近距离dn、高边方位θn和北向方位φn。
然后执行步骤S4，将目标井轨迹校准到救援井基准上,特别地，校准方式根据井斜角不同有所区别；具体请参考图3A所示，在本申请一实施例中，通过所述相对位置将目标井轨迹校准到救援井基准还包含：
S301将所述救援井的井斜角与预设阈值比较，根据比较结果获得预设的校准策略；
S302根据所述校准策略通过所述相对位置将目标井轨迹校准到救援井基准。
进一步的，请参考图3B所示，在本申请一实施例中，根据所述校准策略通过所述相对位置将目标井轨迹校准到救援井基准包含：
S303当所述救援井的井斜角小于预设阈值时，计算同垂深下救援井与目标井的水平距离；
S304根据所述水平距离计算获得目标井在同一垂深下的分析坐标数据，并根据目标井的历史测斜数据计算获得对应垂深下的原始坐标数据；
S305通过平移目标井井口将所述原始坐标与分析坐标数据重合，使得目标井轨迹校准到救援井基准。
再请参考图3C所示，在本申请另一实施例中，根据所述校准策略通过所述相对位置将目标井轨迹校准到救援井基准包含：
S306当所述救援井的井斜角大于预设阈值时，计算救援井在预设井深下法面扫描的目标井垂深，以及，救援井与目标井最近距离在水平面的投影数据；
S307根据所述投影数据计算获得目标井在所述目标井垂深下的分析坐标数据，并根据目标井的历史测斜数据计算获得对应垂深下的原始坐标数据；
S308通过平移目标井井口将所述原始坐标与分析坐标数据重合，使得目标井轨迹校准到救援井基准。
在实际工作中，当救援井井斜角αn小于10°时，校准过程如下：
计算同垂深下救援井与目标井的水平距离Dn，公式为：
计算目标井在同一垂深zn下的坐标(Xn,Yn,Zn)，公式为：
根据目标井历史测斜数据可以得到处该垂深下的原始坐标(X′n,Y′n,Z′n)。
然后平移井口，使得目标井历史测斜数据得到的原始坐标(X′n,Y′n,Z′n)与测得的坐标(Xn,Yn,Zn)重合。
当救援井井斜角αn大于10°时，校准过程如下：
计算救援井预设井深下法面扫描的目标井垂深Zn，公式为：
计算救援井与目标井最近距离dn在水平面的投影公式为：
计算目标井在垂深Zn下的坐标(Xn,Yn,Zn)，公式为：
根据目标井历史测斜数据可以得到处该垂深下的原始坐标(X′n,Y′n,Z′n)。
然后平移井口，使得目标井历史测斜数据得到的原始坐标(X′n,Y′n,Z′n)与测得的坐标(Xn,Yn,Zn)重合。
以此可以消除仪器之间的累积误差。
在前述步骤完成的基础上即可执行步骤S5，反推计算得到轨迹平稳段救援井与目标井的井斜角和方位角的角差，具体可参考图4所示，计算所述救援井与所述目标井之间的角差包含：
S401将所述相对位置转换为笛卡尔坐标系；
S402根据所述笛卡尔坐标系反推计算获得所述救援井与所述目标井之间在井斜角和方位角的角差。
实际工作中，其实现步骤如下：
将磁导向测量系统得到第li处的救援井与目标井的相对位置关系转换到笛卡尔坐标系，公式为：
同样地，对轨迹平稳段(井斜α0)第lj处的救援井与目标井的相对位置关系转换到笛卡尔坐标系，从而得到dj,x和dj,y。
反推计算得到井斜角角差Δα和公式为：
于是可以将目标井井斜角和方位角校准到与救援井统一基准，消除仪器之间的相对误差。
最后，即可进行步骤S6按照校准后的井斜角和方位角给出轨迹调整的预测值，具体过程为S5的逆推形式。
