斜井层位标定技术及其应用
|
摘要
随着油田勘探开发的深入，对许多岩性、裂缝性、地层不整合、低渗透性及高陡构造等特殊圈闭类型的油气藏的勘探开发，已广泛采用斜井技术，斜井层位标定技术是储层研究和油藏描述中的关键技术之一。本文从斜井轨迹方程入手，论述了斜井的层位标定技术，介绍了空间层位标定和虚拟井层位标定的两种方法原理，并以斜井测井信息为纽带，建立起标志层和主力油层与地震剖面上反射同相轴的对应关系。通过实际应用具有较好的实用性。
The deviated well technology has found extensive application in the exploration and devel-opment of special-trap type oil and gas reservoirs such as lithologic, fractured, stratigraphic unconformi-ty, low permeability, and high-dip structure traps. The horizon calibration technique of deviated wells is one of key techniques for reservoir characterization. In this paper we start with the deviated well trajec-tory equation, discuss the technique, and introduce the principles for both space and virtual well horizon calibrations. Taking the deviated well log information as a link, we then construct the corresponding re-lation between the seismic reflection events and the marker layers or the main oil layers. Actual applica-tion results prove the practicality of the technique.
