Coring and Pressure Measuring Integrated Logging Tool and Its Application
To meet the oil company to the urgent need of formation fluid and large volume of core,an integrated logging tool is designed to guarantee the exploration of the formation fluid and core sample which can fully meet the demand of material physical properties laboratory analysis,get the characteristics of lithology and oil content of each rock,and directly test the formation pressure and fluid samples.The integrated logging tool can get the 38.1 mm in diameter,55 mm core and real formation sample.It can measure pressure and sample the formation by setting PARKER and setting the formation.It can also drill into the formation with a hollow diamond bit controlled by mechanical motion mechanism at the same depth and use the coring motor to drive the hollow diamond bit to rotate at high speed to obtain the large-diameter core in the same layer as the fluid sample.The development of the integrated logging instrument,with a variety of operation modes,greatly improves the efficiency of the operation and the core and fluid harvest rate.The equipment has been widely used in typical complex well conditions such as land oil and gas wells,loose coal seams,large deviation wells,small hole wells and so on,proving that the formation adaptability of the instrument is strong,safe,and reliable.
