【摘要】：高3618塊蓮花油層為一厚層塊狀稠油純油藏,含油面積1.16km2,地質(zhì)儲(chǔ)量1323.3×104t,標(biāo)定采收率14.6%。于1987年采用蒸汽吞吐開(kāi)發(fā)方式投入開(kāi)發(fā),近年來(lái)受油藏地質(zhì)特點(diǎn)及蒸汽吞吐末期采出程度高,地層壓力水平低,繼續(xù)吞吐效果差等影響,產(chǎn)量遞減較快,最終采收率低。本次結(jié)合區(qū)塊已完鉆井的鉆井、錄井、測(cè)井及三維地震等資料,利用精細(xì)地層對(duì)比技術(shù)、儲(chǔ)層綜合評(píng)價(jià)技術(shù)、測(cè)井識(shí)別技術(shù)、地質(zhì)建模技術(shù)、剩余油研究及數(shù)值模擬技術(shù)等,綜合對(duì)高3618塊蓮花油層的構(gòu)造特征、沉積特征、儲(chǔ)層特征、油藏類型、油水關(guān)系、地質(zhì)儲(chǔ)量、蒸汽吞吐開(kāi)采效果、剩余油分布規(guī)律進(jìn)行深入研究與評(píng)價(jià)。在此基礎(chǔ)上,根據(jù)精細(xì)油藏描述地質(zhì)體認(rèn)識(shí)和剩余油分布和潛力提出了下一步提高采收率的合理開(kāi)發(fā)方式。
[Abstract]:The high 3618 Lianhua reservoir is a thick layer thick oil pure oil reservoir with an oil area of 1.16km2 and a geological reserve of 1323.3 x 104t. The calibrated recovery rate 14.6%. was developed by steam stimulation development in 1987. In recent years, the reservoir geological characteristics and the stage of steam stimulation at the end of the period are high, the level of the ground pressure is low, and the effect of continuous huff and puff is poor, and so on. In this combination, the drilling, logging, logging and 3D seismic data have been completed in this area, and the structural characteristics of the 3618 High lotus oil layers are integrated with fine stratigraphic contrast technology, comprehensive reservoir evaluation technology, logging recognition technology, geological modeling technology, residual oil research and numerical simulation technology. The product features, reservoir characteristics, reservoir types, oil and water relations, geological reserves, the effect of steam huff and puff exploitation and the distribution of residual oil are deeply studied and evaluated. On this basis, a reasonable development method for the next step of high recovery is proposed based on the description of the geological body and the distribution and potential of the remaining oil in the fine reservoir.
