Özet:
It is known that the absorption of the circulated solution is one of the most common complications during the drilling of oil and gas wells. The time spent on eliminating such complications annually is on average 350–400 thousand hours. It is no coincidence that the reduction of the well construction cycle by about 25–30% is achieved due to the improvement of methods and means of combating the absorption of tamponage and washing solutions into the formation during drilling, solidification, as well as repair and isolation works. The processes of absorption by the formation are characterized and correlated with permeability, porosity, strength of the collectors, formation pressure, thermal conductivity, formation energy loss, reservoir enthalpy, volume and quality of the injected washing and drilling solution. It should be noted that the absorption of the solution occurs when the permeability and energy transmissibility of the formation have significantly increased after hydraulic fracturing and the pressure difference between the well and the layer absorbing the solution has exceeded the critical limit. Many years of experience show that the best and most qualitative method of treating a boil is early diagnosis of the process of its formation.
