| Abstract | Foreign near-bit measurement technology was first developed in 1920 and has become increasingly mature. It started relatively late in China, and is still in the test stage. This paper introduces the development course of near-bit measurement technology at home and abroad, and introduces the targeted market using the best five technologies: near-bit DQNBMS-1 type of MWD system, Pathefinder near-bit geological drilling technology, nearbit CGDS LWD system, nearly bit CGDS LWD system, MRC near-bit geological system. The downhole data transmission mode of the near-bit measurement system can be divided into three types: acoustic wave, mud pulse and electromagnetic tracking measurement system. , according to the technical characteristics of near-bit analysis in Fuling area and field application situation of Shengli oilfield, real-time acquisition underground strata information, timely and accurately reflect the true physical underground, combined with logging data to complete real-time formation evaluation, the stratigraphic classification more reasonable, the reservoir porosity and fluid types of discrimination is more scientific, and improve the reservoir drilling rate. |
