地层测试(试油)技术的发展及展望

Development and Prospect for Well Test(Oil Test) Technology

试油是探井钻井中和完井后,直接测取油气储层压力、产能、流体性质和地层参数的有效方法,也是提高勘探开发经济效益的重要途径之一。我国试油技术研究起始于20世纪60年代至70年代末期,其后,各油田结合不同的区块储层条件及工具装备实际,经过多年的试油生产实践,将上提下放类地层测试技术(MFE、HST、膨胀工具)、压控测试技术(APR、PCT、TTV、STV)、射孔技术、泵排技术、酸压技术进行单项或多项技术融合、创新,形成了适合不同储层条件、不同井况的试油工艺,为各油田的增储上产和快速发展做出了重大贡献。但随着勘探技术的不断进步,试油技术如何向智能化、一体化方向发展,更好地解决各类复杂油藏、特殊井况仍然引人深思。

The well test is an effective method to acquire oil and gas reservoir pressure,capacity,fluid properties and formation parameters directly during drilling and completion period of the exploratory well,is also one of the important ways to improve the economic benefit of exploration and development. Research of testing technology in China began in the 1960 s to the late of 70 s,later every oil field combines with different block reservoir conditions and practical tool and equipment,integrates and innovates the single or multiple technology to lift down formation testing technology( MFE,HST,expansion tools),pressure-controlled testing technology( APR,PCT,TTV,STV),perforating technology,pump discharge technology,acid fracturing technology continuously through years of testing,production practice,which develops and improves the well test technology rapidly to form a oil test process suiting for different reservoir and well conditions,making a significant contribution to reserve and oil increment and the rapid development of each oil field. But along with the advance of exploration technology,how to develop in the direction of intelligent,integrated of well test technology to better resolve all kinds of complex reservoir and special well conditions is still thought-provoking.
