On March 21, the reporter from China petroleum logging company changqing division interpretation center learned that in the process of well drilling in northwestern ordos basin, using imaging logging data, comprehensive explanation results after expert group consultation, which will provide referential basis for the perforation and transformation of the late, after testing single commercial oil flow being made 121.72 tons/day, is in the region and a high yield well.

Higher resolution imaging logging, detecting depth further, is to address the complex geological problems of the telescope and microscope. In recent years, ji in northwest tableland area is the key area of changqing oilfield exploration, but the new formation of fluid property recognition is the interpretation of the difficulty in this area. , changqing department to strengthen the adaptability logging series technology research, in view of the geological characteristics of the imaging logging acquisition advice, help technical personnel detailed interpretation evaluation, provide reference for decision-making of exploration and development.

With the deepening of exploration and development degree, ordos basin, the geological target more and more complex, in the grindstone formation has more and more difficult to find favorable oil and gas enrichment dessert. Imaging logging technology is a complex geological and engineering problems of one's speciality, is indispensable to assess regional comprehensive geological and engineering logging technology. Changqing department promote the scale of the application of imaging logging technology comprehensive application in 2016 domestic "3 electric 2 1 nuclear magnetic imaging well logging instrument is 5603 times, an increase of 43.3% over the previous year. Among them, the company independently developed the multifrequency nuclear magnetic resonance (NMR) logging instrument applications in 70 Wells, effectively improve the density of complex reservoir, such as oil, water flooded layer interpretation accuracy.

On this basis, the changqing department research imaging logging evaluation technology, developed based on the imaging data of formation pore structure, hole seam, rock mechanics parameters, such as reservoir quality and heterogeneity quantitative evaluation technology, formed a double degree of saturation and pore space modulus array acoustic water accurate identification technology series of oil and gas.

Scale application of imaging technology, solve the complex lithology, complex formation water storage Spaces, complex reservoir fluid identification problems, provide strong technical support for oil and gas field exploration and efficient development.
