目前大庆喇嘛甸油田已进入特高含水期开采阶段,各类储层动用状况存在很大差异,油层水淹状况差别很大,剩余油分布十分分散,挖潜难度极大,水淹层解释较为困难,其中尤以厚油层、薄差层为甚。本文根据井壁取心资料,建立了水淹层综合解释评价方法,几年来,在喇嘛甸油田新钻调整井中应用200多口井,综合解释符合率达87.2%,提高了喇嘛甸油田厚油层、薄差层精细评价水平,并为新钻调整井选层射孔提供了可靠依据。
At present, Lamadian Oilfield in Daqing has entered the stage of extra-high water cut. There are great differences in the utilization of various types of reservoirs. The flooded conditions of oil reservoirs vary greatly and the distribution of remaining oil is very scattered, making it extremely difficult to tap the potential, making it difficult to interpret water flooded layers , Especially thick oil layer, thin layer is even worse. In this paper, based on the wall coring data, a comprehensive interpretation and evaluation method of water flooded layer was established. Over the past few years, more than 200 wells were drilled in newly drilled adjustment wells in Lamadian Oilfield, with the coincidence rate reaching 87.2%, raising the thick oil layer , Thin layer of fine evaluation of the level, and new drilling adjustment wells perforated election provided a reliable basis.
