METHOD FOR DIRECTING CUMULATIVE CHARGES (VARIANTS), DIRECTED SHOOTING PERFORATOR (VARIANTS), METHOD FOR PLACING WELL COMPONENTS (VARIANTS), RIGID CENTERING HOLDER, DEVICE FOR MEASURING DIRECTION Russian patent published in 2004 - IPC

FIELD: perforation technologies.

SUBSTANCE: method includes increasing weight of one or more components of perforators column, while in one or more component material is partially removed for changing gravity center. Directed shooting perforator has one or more cumulative charge having cover, charge body and charge pipe. One or more component of perforator is eccentrically increased in weight, and other one or more components have some material removed eccentrically. Method for placement well components includes lowering one or more focused detectors. One or more well components is detected. Their position is displayed by gyroscope. Rigid centering holder contains transfer sleeve, waist ring, spring stopping ring and stopping ring. Device for measuring direction of cumulative charges has detonating wire and checking device made with possible activation by detonation of detonating wire. Checking device is made with possible use on both ends of perforators column.

EFFECT: higher efficiency.
