ARRAY LATEROLOG RESPONSE AND RAPID CORRECTION OF THE SURROUNDING ROCK/LAYER THICKNESS INFLUENCE FOR HIGHLY DEVIATED/HORIZONTAL WELLS
摘要
Abstract
Due to the influences of the surrounding rock/layer thickness,the laterolog response of the array can not accurately reflect the actual resistivity of the reservoir,the surrounding rock/layer thickness correcting plate in the condition of the straight/vertical well is no longer suitable for the horizontal and high-inclination wells,so it is necessary to quantitatively correct the influences of the surrounding rock/layer thickness,and moreover the corresponding correcting plate was developed.With the help of the built 3D ball-like media model and finite element method,the response characteristics of the array laterolog in the horizontal and high-deviated wells were researched.On the basis of the 3D numerical calculation,the corresponding correction plate was established and furthermore by means of the nonlinear analyzing technique,the nonlinear correcting formula and the correcting plate were obtained for the instrument response.The study achievements show that the array laterolog response is obviously influenced by the sizes of the well inclination,the more the inclined angle is,the more obvious the influence will be.When the reservoir thickness is less than 2 m,the resistance is seriously influenced by the surrounding rock;while when the thickness is more than 6 m,there are no corresponding influences no matter how much the inclination angle is.The comparison discovers that there is much better consistency between the rapid correcting plate and the one of the numerical simulation,so it can be adopted for the fast real-time correction of the array laterolog response.关键词
