精细地质导向模型在提高水平井钻井成功率方面的应用研究

Applied Research of Building Geo-pilot Model to Increasing the Success of Horizontal Well

地质导向技术在开发薄油层、致密油气层、复杂断块油藏、油水关系复杂油藏等方面发挥了重要的作用。本文以某油田B6h水平井为例,应用Geo Steer RT随钻实时地质导向软件,通过建立精细的前导地质模型,并在实钻过程中根据不断更新的实时数据,及时修正、精细刻画地质模型,准确预测、判断钻遇目的层,预测地层倾角变化,确定钻穿油层的位置,及时给出钻完井建议,大大提高了实时决策的科学性,取得了良好的经济效益,为应用水平井开发层状构造油气藏提供了有益的借鉴。

The technology of geo-pilot is very important in the development of thin,compact,implicated reservoir. This article takes B6h as the example,by using the GeoSteerRT software,and constructing the geo-model,and renewing the real-time data,it revised and anticipated the pay-top,and make sure the situation of the track,and gave the advice of next step. The scientific nature of real-time decision-making has been improved,and good economic benefit has been obtained,which can provide useful reference for developing the layered structural reservoir of horizontal wells.
