Abstract

Предложен сжимаемый объект, который может быть использован в буровом растворе и в бурильных системах для регулирования плотности бурового раствора. Сжимаемый объект включает оболочку, которая заключает внутреннюю область. Сжимаемый объект имеет внутреннее давление, превышающее значение около 200 фунтов на квадратный дюйм при атмосферном давлении и выбранное для заданного наружного давления, в котором наружные давления, превышающие внутреннее давление, сокращают объем сжимаемого объекта, при этом оболочка спроектирована для снижения местных напряжений в сжимаемом объекте при его расширении и сжатии.A compressible object is proposed that can be used in drilling mud and in drilling systems to control the density of the drilling fluid. The compressible object includes a shell that encloses the inner region. A compressible object has an internal pressure greater than about 200 pounds per square inch at atmospheric pressure and selected for a given external pressure, in which external pressures greater than internal pressure reduce the volume of the compressible object, while the shell is designed to reduce local stresses in the compressible object at its expansion and contraction.
