摘要： 传统单项录井解释方法由于自身技术局限往往适用性较差,需要根据不同油气性质建立不同图板,其种类繁多且需要提前进行人工油气性质判别。为此通过将气测录井与地化录井的关键参数Tg、Pg进行组合,进一步提出了Tg-Corr和Pg·PS两个修正参数,建立了一套受油气性质影响较小,且适用性较强的油气水解释组合图板。该图板在渤海油田20个二级构造带油气水解释应用的结果表明,平均解释符合率达到86.3%,显著提升了井场油气水录井解释精度;同时该方法的成功应用也为录井解释提供了一种新的思路,具有一定的推广价值和应用前景。

Abstract: Traditional single mud logging interpretation methods often have poor applicability due to their own technical limitations, requiring the establishment of different charts based on different oil and gas properties. There is a wide variety of charts to manually discriminating oil-gas properties in advance. Therefore, by combining the key parameters Tg and Pg of gas logging and geochemical logging, two corrected parameters Tg-Corr and Pg·PS are further proposed to establish a set of oil-gas-water interpretation combination charts with less influence from oil-gas properties and strong applicability. The application results of the charts in oil-gas-water interpretation of 20 second-order structural belts in Bohai Oilfield show that the average interpretation coincidence rate reaches 86.3%, which significantly improves the mud logging interpretation accuracy of oil,gas and water in well site. The successful application of this method also provides a new idea for mud logging interpretation, which has certain popularizing value and application prospects.

Key words: Bohai Oilfield, second-order structural belt, gas logging, geochemical logging, combination chart, interpretation accuracy
