Application of geo-steering technique in mengping-1 well.;

The Application of MWD GAMMA Survey Technology in Geo-steering Drilling;

In view of the DOA of the other signals attained from the weight vector of the algorithm the steering vectors matrix of the interference signals are established.

Within the null space of the steering vectors vectors matrix of interference signals, the weight vector which is closest to the steering vector of the expected signal and deeply depresses the interference signals simultaneously comed be obtained with least square method through the linear combination of orthogonal basis.

On the basis of analysis of constraint equations,the actual space-time steering vectors of the desired signal can be solved using the Lagrange multiplier methodology.
