摘　　要：江汉油田开展剩余油挖潜增效已进入了攻坚战的阶段,一般难度较大的三维定向井都设计成“S”型井眼轨迹,王4斜-5-3B井受地面条件限制,必须设计成“Z”形井眼轨迹才能达到地质要求。介绍三维“Z”形斜面圆弧井眼轨迹控制的技术难点与施工对策,为今后开展拐急弯变方位特殊定向井的研究与应用,奠定了一定的基础。The development of looking for surplus oil and improving the efficiency in Jianghan Oilfield is launching an attack against the heavily fortified positions. Generally speaking, the three-dimensional directional wells with difficulties are all designed with＂S＂ shaped borehole trajectory. With the restrictions of the aboveground conditions, Wang 4 inclined-5-3B must be designed with ＂Z＂ shaped borehole trajectory to meet the geological demands. This article introduces the technological difficulties and construction countermeasures of the control technology for borehole trajectory on three-dimensional＂Z＂ shaped circular arc with inclined planes, which establishes a certain base for the future research and application on special directional wells of turning emergent comer and changing direction.
