随钻测井是实现地质导向钻井的关键技术之一,在地质勘探和油藏开发中发挥着重要的作用。随钻测井技术是地质导向的核心技术,其中四参数组合LWD仪器(电阻率、密度、中子和自然伽马)已成为标准的随钻测井仪器,被广泛应用于地质导向和地层评价中,在地质勘探和油藏开发中发挥者日益重要的作用。由于我国在随钻测井技术研究方面与国外差距较大,严重地影响了地质导向钻井技术在我国的应用。因此该技术研究必将极大地促进我国随钻测井和地质导向钻井技术的发展,扩大该技术的应用规模,缩短与国际先进水平的差距,具有显著的经济效益和社会效益。
Logging while drilling is one of the key technologies to realize the geosteering drilling and plays an important role in geological exploration and reservoir development. While LWD technology is the core technology of geosteering, four-parameter LWD instruments (resistivity, density, neutron and gamma ray) have become the standard logging-while-drilling tools and are widely used in geosteering and stratigraphic evaluation In the geological exploration and reservoir development play an increasingly important role. Due to the large gap between China and other countries in the logging-while-drilling technology research, the application of geosteering drilling technology in our country has been severely affected. Therefore, this technology research will greatly promote the development of LWD and geosteering drilling technology in our country, expand the application scale of this technology and shorten the gap with the international advanced level, with significant economic and social benefits.
