An ordinary horizontal well consists of vertical section,curve section and horizontal section. Radial horizontal well is the most complicated one in horizontal well series,it has a major horizontal section and one or several branch sections. The design of a horizontal well includes the steps: 1)designing the horizontal section in the light of drilling target and reservoir configuration,which involves determination of the coordinates of starting point,ending point and control points ; 2 )using the starting-point...

An ordinary horizontal well consists of vertical section,curve section and horizontal section. Radial horizontal well is the most complicated one in horizontal well series,it has a major horizontal section and one or several branch sections. The design of a horizontal well includes the steps: 1)designing the horizontal section in the light of drilling target and reservoir configuration,which involves determination of the coordinates of starting point,ending point and control points ; 2 )using the starting-point parameters to calculate well-head coordinate and curved-section parameters:locus coordinates, curvature, vertical and horizontal displacements. Branch sections are designed to ascertain oil-water contact in slant reservoir. Control point parameters of branch sections are designed in the same way for the horizontal section.

普通水平井轨迹由三部分组成:直井段,造斜段,水平段。辐向水平井是水平井系列中的高难度井,它除了有一段水平井段外,还有另外一条或多条分支井段。在实际设计水平井时,首先根据钻探目的及油气藏的空间组合模式设计水平井段,确定始靶点、终靶点及各轨迹控制点的坐标,然后按始靶点轨迹参数反推,设计造斜段的造斜点坐标、造斜率及垂直、水平位移,并确定井口坐标。设计分支井的目的主要是探明倾斜油层的油水界面,分支井段各控制点参数的设计方法与水平段类似。

LWD(logging while drilling) is a new logging technology developed in recent years, its main charateristic is logging can be run while drilling. It is a good solution for ERD (extended reach drilling) well logging when it is hard to use wireline well logging. The application of LWD in ERD well is analyzed and compared with wireline (i.e. drill pipe convey) logging. The comparison indicates that LWD is a best choice in ERD wireline well logging. And LWD advantages as well as its application environments are described.
