发明名称 Apparatus and methods for obtaining measurements below bottom sealing elements of a straddle tool
摘要 The present invention provides methods and apparatus for obtaining downhole well pressure during wellbore operations. One method comprises providing a well intervention tool comprising a straddle sealing assembly having upper and lower annulus sealing elements and a fluid injection port positioned therebetween, the well intervention tool comprising a fluid injection bore having positioned therein a pressure measurement tool; placing the tool in straddle position about a wellbore region to be intervened, with the pressure measurement tool fluidly connected to a wellbore region below the lower annulus sealing element; and performing the wellbore intervention operation while communicating fluid from below the lower annulus sealing element to the pressure measurement tool, thus obtaining a pressure measurement below the lower annulus sealing element during the wellbore intervention operation. This abstract will not be used to interpret or limit the scope or meaning of the claims.
