Establishment and Application of Electronic Well Location Information Template for Anticollision in Drilling Wells;

A simple method of discriminating well locations according to "well points in polygon";

3D seismic interpretation, comprehensive well log interpretation and reservoir numerical simulation are applied to study the direction of sand distribution in accordance with the characteristics of thin oil reservoirs with bottom water and to optimize well location and horizontal interval as per screen criterion.

The selection method of well position is putted forward.

Application of GPS and whole-station instrument in improving precision of well-site measurement;
