Description
Technical field
The core of getting that the disclosure relates generally to downhole drill operates, and more particularly, relates to drilling tool and the method for using with getting core well logging acquisition down-hole core sample measured value.
Background
Conventional logging technology as rope and well logging during (LWD) have employed the instrument of use sensor special from the surrounding formation collection data of well.Signal transmission between transmitter and receiver is by very complicated open environment, and described environment is subject to the impact of noise, multipath propagation, erosion, mud cake and intrusion problem.These borehole conditions greatly increase cost and the complexity of instrument, and affect its reading accuracy.Intrinsic geometric layout together with instrument is limited the direction of the classification of spendable measurement/sensor, data acquisition resolution ratio and measurement by this
The conventional tool that bit face for the end from well obtains core employs special coring bit to collect cylindrical core sample.Subsequently, depend on the information type that will collect, check at earth's surface place by various equipment and technology and analyze core sample.For example, core sample can provide the instruction of formation character, and described formation properties is as the porosity of down-hole formation, permeability and other physics or petrophysical property.
In typical operation, during coring bit is used in drill-well operation, collect the continuous core sample at bit face place.Can collect near coring bit and deposit multiple core sample.After collecting requisite number object sample, core sample is risen to earth's surface to measure the character of sample.Little chock (plug) is just extracted from core sample in most of laboratory, and provides the relatively small number destination data point crossing over whole well.
But rising in the process on earth's surface by core sample, core sample can be damaged or lose.Therefore, conventional system is typically included in and supports when core sample being risen to earth's surface and to protect the parts of core sample.Contact between drilling fluid and core sample may be lost after a while to the measurement that core sample is made.In addition, the mechanical force during the removing and promote of core sample can cause core sample to break, and this may make the ability gathered information from core sample complicate.When core sample is transported to laboratory or be otherwise transported to research point, described core sample can be demoted further.Incorrect or inconsistent value from core sample may have serious impact to well drill-well operation.
