完井方式对适度出砂井产能的影响研究

为了完善近几年提出的海上稠油油藏开采新模式中的部分技术——以钻井压裂、适度出砂、电潜螺杆泵为主的钻采工艺配套技术体系，根据不同完井方式（包括裸眼完井、射孔完井、筛管完井等）下钻井压裂井的表皮系数模型和产能模型，研究了不同完井方式下不同技术参数对钻井压裂适度出砂井的产能影响，结果表明，这些参数都不同程度地影响着井筒周围的出砂带物性，进而影响油井产能；在用适度出砂方式开采时，要严格评价完井方式及其技术参数对出砂带物性和产能的影响。

THE INFLUENCE OF WELL COMPLETION WAY ON PRODUCTIVITY OF REASONABLE SAND PRODUCTION WELL

In order to perfect the nearly presented partial technology in new mode of effective development of offshore heavy oil field,that is the drilling and production support technological system which takes drilling fracturing well,limited sand production and electric submersible progressive cavity pump as main technologies,according to the skin factor model and productivity model of drilling fracturing well with different completion ways including barefoot completion,perforation completion and screen pipe completion etc,the influence of different technology parameters of different completion ways on reasonable sand production well is researched.The result indicate these parameters impact the physical property of sand production belt and thereby the oil well productivity to some extent.It is necessary to strictly estimate the influence of completion ways and its technological parameters on the physical property of sand production belt and thereby on the oil well productivity.
