    摘要:

    山东新汶矿业集团ZJ02—PJ02对接井,直井ZJ02设计深度为94112 m,斜井PJ02井设计深度为120300 m,两井相距25200 m。设计井身为三开结构并合理配置钻探及造斜专用设备;为防止井斜采用塔式钟摆钻具;根据不同井段,合理选用钻压、钻速和泵量,配制不同的钻井液;采用高精度的PST随钻测斜和最小曲率法计算钻井轨迹,保证了两井的顺利对接连通。

    Abstract:

    The paper introduced ZJ02-PJ02 butted wells of Xinwen Mining Group, the designed depth of the shaft and the inclined well were 94112m and 120300m, and these two wells was 25200m apart. The designed well structure was trisected with drilling and angle building equipment rationally installed. Tower-type pendulum drilling-assembly was used to prevent well deviation. Drilling pressure, drilling ratio, pumping volume and drilling fluid were selected according to the different situation in different well section, highprecision PST MWD and minimum curvature method were applied to calculate the drilling trajectory to guarantee the butting of two wells.
