Technical Field

[0001] The invention relates to the field of petroleum logging, and in particular to a cableless logging data processing method, system, terminal and storage medium thereof. Background Art

[0002] In the later stage of oilfield development, the development objects become more and more complex and the development difficulty becomes greater and greater. The number of large-displacement horizontal wells and high-angle wells gradually increases. These wells usually have the characteristics of shallow casing, open hole section deviation near the casing mouth, shallow inclination point, complex well conditions (step or threaded wellbore, diameter expansion and contraction, large dogleg, serious leakage, etc.), long horizontal section displacement, etc., and some complex wells with very serious obstruction often appear.

[0003] In the prior art, cable logging is usually used for measurement. However, for complex wells with very serious obstructions, the cable is often stuck in the complex well. Usually, the cable stuck in the complex well is removed by hard pulling or cutting. Under this operation, it may lead to inaccurate data collection at best, and even terminate the logging data collection at worst, which greatly affects the acquisition of data parameters of the oil field wells. Summary of the invention
