引言在钻井过程中,泥浆压力大于地层压力(或经加重处理后大于地层压力),泥浆漏入地层的消耗为井漏,其量称为漏失量(简称漏失)。观测漏失,是钻井地质工作中必不可少的录井手段之一。特别是开发卤,气藏在布井时,就有意识地把井位布置在渗透性良好的部位,如断层、溶洞、裂隙发育的地段则是卤、气储集的良好空间。在钻遇中 Introduction During drilling, mud pressure is greater than formation pressure (or greater than formation pressure after aggravating treatment). The amount of mud leakage into the formation is the loss of circulation, which is called the loss (or loss). Loss of observation is one of the essential logging tools in drilling geological work. In particular, the development of brine and gas reservoirs in wells, it is consciously arranged wells in well-permeable parts, such as faults, caves, cracks in the development of the site is halogen, gas storage space. In drilling encounter
