定录导一体化技术服务系统开发及应用

Development and application of the directional,mud logging and geosteering integrated technology service system

在油田开发的中、后期,为了节约成本和提高采收率,各种类型的定向井竞相展开。为了确保定向井准确命中靶点,提高钻遇率,常规的几何导向已经不能满足现场需要,地质导向技术能够解决上述问题。基于目前现有装备及工艺特点,文章提出用于地质导向的定录导一体化技术。在定录导一体化技术和现场作业特点基础上,开发了定录导一体化技术服务系统软件。通过系统现场应用,在A靶着陆、水平段轨迹调整方面都取得了很好的效果,为水平井地质导向提供了新的服务模式,有益于勘探开发。

In the middle and later period of oilfield development,in order to save cost and improve the recovery efficiency,various types of directional wells are developed. Conventional geometric orientation already cannot satisfy the field needs. In order to ensure directional wells hitting its targets and improve drilling encounter rate,geosteering technology is apply to solve the above problems. Based on the existing equipments and technologies,directional,mud logging and geosteering integrated technology is put forward. Based on this technology and onsite operation features,directional,mud logging and geosteering integrated technology service system software was developed. Through field applications,good results of landing on A target,horizontal section trajectory adjustment have been achieved. This system provides a new service mode for the horizontal well geosteering and benefits the oil field exploration and development.
