【摘要】：曹妃甸油田群河流相底水油藏是渤海海域已開(kāi)發(fā)的一類重要油藏類型,采用不規(guī)則水平井井網(wǎng)開(kāi)發(fā),目前大多數(shù)油藏已進(jìn)入中、高含水階段,但采收率偏低,亟需理清剩余油分布規(guī)律和主控因素,指導(dǎo)油田下步綜合調(diào)整。曹妃甸油田群新近系館Ⅲ油組下段儲(chǔ)量大、開(kāi)發(fā)井多,是一個(gè)已進(jìn)入高含水開(kāi)發(fā)期的小氣頂?shù)头鶚?gòu)造強(qiáng)底水油藏。通過(guò)靜態(tài)地質(zhì)資料和動(dòng)態(tài)生產(chǎn)資料相結(jié)合,認(rèn)為微構(gòu)造形態(tài)和小斷距斷層等構(gòu)造因素、河漫灘成因夾層、油水界面差異、油田早期開(kāi)發(fā)理念、目前開(kāi)發(fā)井網(wǎng)等5大因素控制了研究區(qū)剩余油分布。在以第2期夾層為界的上、下開(kāi)發(fā)層系中,剩余油分布具有一定規(guī)律性。上開(kāi)發(fā)層系剩余油主要分布在油環(huán)井網(wǎng)不完善區(qū)域,下開(kāi)發(fā)層系剩余油主要分布在油藏西部的油水界面較低及井網(wǎng)不完善區(qū)域、中部的水平生產(chǎn)井和氣油界面之間、第4期主力夾層下部構(gòu)造高部位以及距開(kāi)發(fā)井較遠(yuǎn)的斷層附近。
[Abstract]:Fluvial bottom water reservoir of Caofeidian oilfield group is an important reservoir type developed in Bohai Sea area. It is developed by irregular horizontal well pattern. At present, most of the reservoirs have entered the stage of middle and high water cut, but the oil recovery is on the low side. It is urgent to clarify the remaining oil distribution law and main control factors to guide the next comprehensive adjustment of oil fields. The lower member of the Neogene Gun 鈪，
