旋转导向随钻测井在长庆油田致密油水平井实验区的应用

Application of Rotary Steering Logging While Drilling to Dense Oil Horizontal Well of Experimental Area in Changqing Oilfield

水平井开发作为提高单井产量的重要手段已在长庆区块普遍应用,但在致密油区块优质、高效地完成薄油层长水平段钻井已成为水平井开发的技术难点。在长庆油田致密油开发实验区,宁平×井应用旋转导向随钻测井技术安全优质地完成该井的测井、定向、导向及解释评价一体化的随钻测控服务,取得了良好的应用效果,为长庆油田致密油水平井开发摸索出了一套系统的解决方案。

It has been commonly applied that horizontal well is important means to improve the single well production,but how to efficiently complete drilling in thin dense oil reservoir with long horizontal section is the technical difficulty in developing horizontal wells.We applied the rotary steering logging while drilling technology to firstly complete this task which contains logging,directional engineering,geo-steering and log interpretation and evaluation safely and efficiently.Its effect is good,and provides a system scheme for dense oil horizontal well development in Changqing oilfield.
