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。
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.
