Abstract:
In order to prevent a blow out, cooling the bit, displacement of drilling particle, etc., it is necessary to use a suitable fluid called drilling mud. The construction of drilling mud, especially the oil base, has a high cost and covers more than 20% of drilling costs, so maintaining and proper use of it is important, as well as drilling the reservoir layer due to the higher permeability of this layer than Other layers allow the drilling mud to influx into the formation, which in addition to the cost of fluid loss, damage to the reservoir, reduce its permeability and many problems during production. Therefore, in order to investigate the phenomenon of fluid loss, measure its size and provide a suitable method for preventing or reducing it, the design and construction of a simulated environment of the well and around the well was carried out. In this thesis, the stages of designing and manufacturing this device, how to perform the test, the accuracy of the data obtained, and a series of full-scale and comprehensive tests have been investigated
