Research On The Well-logging Evaluation Of Liaohe Archean Buried Hill Reservoir

Liaohe Archean buried hill reservoir belongs to the fractured reservoir, the types of reservoirs in Liaohe oil field development become "stable, guarantee benefit", the main production capacity to replace one of the directions. Explain the evaluation methods are not applicable to this type of reservoir, the conventional reservoir logging interpretation of the past, but due to the use of drilling fluid adding and high density drilling fluid for logging, oil and gas shows new challenges brought about by the recognition, we need to establish a set of suitable to Liaohe Archean Qianshan reservoir logging interpretation and evaluation method.This paper studied and analyzed the lithology and oil reservoir in Liaohe Archaean Qianshan gas characteristics, by the logging technique combined with real drilling data, oil test data, production data, well logging data, based on study of logging technology and logging series of characteristics and advantages, the response analysis of rock in Qianshan reservoir logging, finding an effective way to solve the problem of Qianshan, then these methods are applied to real drilling guide the practical work, the existence of the maximum resolution of the Qianshan geological study of the Archaean and logging problem. The establishment of the Liaohe Archean Qianshan reservoir logging evaluation of reservoir and oil-bearing property evaluation technology system, improve understanding and development effect of Qianshan reservoir.In view of the Liaohe Archean Qianshan reservoir logging evaluation, established logging evaluation method suitable for this type of reservoir, including the drill- drilling speed overlap method and DCS index of Qianshan reservoir identification technology, three-dimensional chart, light hydrocarbon, heavy hydrocarbon gas survey chart- form method evaluation of Qianshan oil and gas technology, the use of gas logging, quantitative fluorescence and identification technology of drilling fluid pollution technology. These methods have been applied and verified in Xing ancient Qianshan, has obtained the good effect in the practical application.
