随钻地质导向技术在川中水平井中的应用
|
摘要
随钻地质导向技术实现了以井下实际地质特征来确定和控制井眼轨迹,达到提高钻井效率和钻遇率的目的。本文分析了随钻放射性和电阻率测井受井眼、围岩、泥浆、各向异性等环境影响因素和校正方法,实际资料处理证实校正结果可信;简述了地震测井联合反演和三维可视化建模在地质导向储层预测中的作用。结合川中磨溪构造××水平井,用随钻测井资料确定中靶点、判断从上部还是下部出层、确定钻头在目的层位置、井眼轨迹调整等方法,最终使得该井目的层钻遇率达到87%,成功实现了地质导向钻井,取得了良好的效果。
LWD(logging while drilling) geologic steering technique can determine and control well track using the actual geologic feature,so,it can raise working efficiency and driiled rate.This paper analyze the environment effect such as borehole、bed rock、mud、anisotropy on LWD radioactive logging and resistivity logging,meanwhile,this paper give a method to correction the effection,the actual result show the correction is reliable;the paper describes how to use seismic -logging joint inversion and 3D geological visualization modeling methods in predicting reservoir of geost- eering drilling.In MoXi structure of Chuanzhong gasfield,this paper uses logging date deciding target、upper or under leaves reservoir、the position of drill bit、adjusting well track,at last,the LWD geological steering technique makes the driiled rate up to 87%,this shows that the LWD system has better application effect.
