摘要
塔里木盆地K区块页岩沉积环境、有机质丰度、成熟度、产层连续厚度及页岩中脆性矿物含量等页岩气评价指标良好,具广阔的勘探开发前景.通过对成熟区块页岩气开发工艺调研,来研究本区块非常规气藏高效钻井工艺.针对地层特征推荐采用51/2″套管射孔完井,确保后期完井、措施作业的顺利进行.由于页岩气藏具有分布广、厚度大的特点,轨迹控制要求可以适当放宽,常规的MWD+随钻电阻仪器测量方式可以满足水平井轨迹控制的需要.
Abstract
In the block K of the Tarim Basin, shale gas evaluation parameters such as shale sedimentary environment, organic matter abundance, maturity, continuous producing layer thickness, and brittle mineral content are favorable, hence show a good potential for exploration. Through the studies of mature blocks for shale gas explorations, effective drilling techniques for unconventional gas reservoirs in the study area were discussed. 51/2″ casing pipes were recommended for perforation and completion. Due to the wide distribution and big thickness of shale gas reservoirs, borehole trajectory control was not strictly restricted. The conventional MWD+ drilling resis-tance instruments worked well in the borehole trajectory control of horizontal wells.
