摘要

Drilling fluid to reduce or control the circulation lost a formation surrounding a borehole subterru00e1nea pit in a process of drilling of a well, the method to reduce or stop the movement lost of drilling fluid to a training subterru00e1nea during the P. Rocesso of drilling of a well.A loss of flow to reduce or control the loss of disposal for a training subterru00e1nea permeable during a process of drilling of a well into a recovery operation of oil or gas.Drilling fluid to reduce or control the loss of outlet for underground permeable formation in a process of drilling of a well into a recovery operation of oil or gas, the method to reduce or control the loss of disposal for a training subterran And the permeable in a process of drilling of a well into a recovery operation of oil or gas.The use of partu00ecculas solid wax with a size of more than 50 microns, the use of an agent of loss distribution and use of drilling fluid comprising a base fluid and an agent of loss of flow movement loss of drilling fluid is one of the most serious problems and more C Frames that are faced by the industry of drilling.The present invention relates to an improved drilling fluid to reduce or prevent the movement lost to an underground formation surrounding a borehole of a well in the process of drilling of a well. The drilling fluid comprises a base and a wax or a fluid. u00e2ncia waxy as an agent of the loss of runoff primary.The invention also provides a method for reducing or preventing the movement lost to an underground formation surrounding a borehole of a well in the process of drilling a borehole using drilling fluid of the invention, in which the agent of loss of primary flow is adding Ionado to drilling fluid before or during drilling.And the drilling fluid is pumped down the borehole during drilling.
