毛细管动态压力监测技术在新疆稠油注蒸汽井中的研究及应用

RESEARCH OF DYNAMIC CAPILLARY PRESSURE MONITORING TECHNOLOGY ON STEAM INJECTION WELLS IN XINJIANG HEAVY OIL AND ITS APPLICATION

随着新疆油田稠油油藏的深入开发,稠油区块所占的比重越来越大,投入开发的六区、九区、克浅十、红浅、百重七等稠油区块的开发方式为吞吐注蒸汽、汽驱和注热水驱,如何科学地获得汽驱井群井下压力动态、吞吐井焖井压力的变化状况,对稠油区块制定科学注采开发方案、实施有效调整措施则显得越来越重要。稠油毛细管动态压力监测技术是为实现稠油注蒸汽井压力监测这一技术要求不断进行技术改造和创新而逐步成熟起来的技术,目前可实现注蒸汽井长期、连续的压力动态监测。

With further development of heavy oil reservoir in Xinjiang oilfields,heavy oil blocks take more predominant proportion.Blocks under development in Block 6,Block 9,KS 10,HS and BH7 use huff-puff,steam and hot water flooding.It is more important to obtain down-hole pressure behaviors of steam driven wells and the pressure differences of braised huff-puff wells scientifically.It is high time to make scientific programme for injection and production of heavy oil blocks to apply more effective adjustment measures.By reforms and innovation,dynamic capillary pressure monitoring technology is now a mature technology used for pressure monitoring in steam injection wells in heavy oil recovery.It helps to achieve long and continuous dynamic pressure monitoring for steam injection wells.
