【摘要】：辽河太古界潜山油藏属于裂缝型油气藏,该类型油藏开发成为辽河油田“保稳产、保效益”最主要的产能接替方向之一。以往的常规储层录井解释评价方法已不适用于该类油藏的解释评价,而且由于钻进液添加和高密度钻井液的使用,给录井油气显示识别带来的新的挑战,因此需建立一套适合辽河太古界潜山油藏录井解释评价方法。本文研究和分析了辽河太古界潜山油藏的岩性和油气特征,通过录井技术结合实钻井资料、试油资料、采油资料、测井资料等,在研究录井技术与录井系列特点和优势的基础上,分析岩潜山油藏的录井响应,寻找解决潜山问题的有效方法,再把这些方法应用到实钻井中指导实践工作,最大限度的解决太古界潜山地质研究与录井中存在的问题。建立了辽河太古界潜山油藏录井储层评价和含油性评价技术体系,提高了对潜山油藏的认识和开发效果。针对辽河太古界潜山油藏录井评价,建立了适合该类油藏的录井评价方法,包括钻时-钻速重叠方法和DCS指数识别潜山储层技术,三维立体图版、轻烃-重烃图版、气测形态法等评价潜山油气技术,利用气测、定量荧光和地化技术识别钻井液污染技术等。这些方法在兴古潜山得到了应用和验证,在实际应用中取得了较好的效果。
[Abstract]:The Liaohe Taigu buried hill reservoir belongs to the fracture-type oil and gas reservoir, which is one of the most important capacity replacement directions in the "stable and stable yield" of Liaohe oilfield. The prior conventional reservoir logging interpretation evaluation method is not applicable to the interpretation and evaluation of the oil reservoir, and the new challenge brought by the identification of the mud logging is displayed due to the use of the drilling fluid addition and the high-density drilling fluid, Therefore, it is necessary to set up a set of evaluation methods for logging interpretation of buried hill reservoir in Taigu, Liaohe. Based on the study and analysis of the lithological and oil-gas characteristics of the buried hill oil reservoir in the Liaohe Taigu, it is based on the characteristics and advantages of the logging technology and the logging series by combining the logging technology with the real drilling data, the test oil data, the oil production data, the logging data and so on. The logging response of the buried hill reservoir is analyzed, the effective method for solving the buried hill problem is found, and the method is applied to the practical work in the real drilling, and the problems existing in the geological research and the recording well of the ancient-boundary buried hill are solved to the maximum extent. The evaluation of the reservoir and the evaluation of the oil-bearing property of the reservoir of the buried hill reservoir in the Taigu-Gujie of Liaohe Oilfield has been established, and the understanding and development effect of the buried hill reservoir is improved. In view of the logging evaluation of the buried hill reservoir in Taigu, Liaohe, a logging evaluation method suitable for this kind of reservoir is established, including the drilling-time-drilling speed overlap method and the DCS index identification buried hill reservoir technology, the three-dimensional perspective version, the light hydrocarbon-heavy hydrocarbon map, the gas-measurement form method and the like to evaluate the oil and gas technology of the buried hill. The technology of drilling fluid pollution and so on is identified by gas measurement, quantitative fluorescence and geochemical technology. These methods have been applied and verified in Xinggu buried hill, and have achieved good results in practical application.
