喇萨杏油田已进入特高含水期开发阶段,剩余油高度分散,厚油层基本上层层见水,但是未水洗厚度比例仍占25%,剩余储量主要集中在河道砂储层,占水驱剩余地质储量的70%.水下分流河道砂体是典型的河道砂体,主要分布在大庆喇嘛甸至杏树岗的非主力油层.以喇萨杏油田水下分流河道砂体为主要研究对象,综合利用密闭取芯检查井、油水井分层测试、测井水淹层解释及生产动态等资料,采用密闭取芯检查井资料分析法、油藏工程方法、油藏数值模拟方法、物理模拟、综合分析法等方法,研究了喇萨杏油田水下分流河道砂体的剩余油形成机理及剩余油影响因素,并提出了剩余油分布模式.
喇薩杏油田已進入特高含水期開髮階段,剩餘油高度分散,厚油層基本上層層見水,但是未水洗厚度比例仍佔25%,剩餘儲量主要集中在河道砂儲層,佔水驅剩餘地質儲量的70%.水下分流河道砂體是典型的河道砂體,主要分佈在大慶喇嘛甸至杏樹崗的非主力油層.以喇薩杏油田水下分流河道砂體為主要研究對象,綜閤利用密閉取芯檢查井、油水井分層測試、測井水淹層解釋及生產動態等資料,採用密閉取芯檢查井資料分析法、油藏工程方法、油藏數值模擬方法、物理模擬、綜閤分析法等方法,研究瞭喇薩杏油田水下分流河道砂體的剩餘油形成機理及剩餘油影響因素,併提齣瞭剩餘油分佈模式.

Lasaxing Oilfield has come into a development stage with ultrahigh water cut and highly decentralized remaining oil. Remaining reserves are mainly stored in channel sand reservoir,which accounts for about 70%of water flooding remain-ing geologic reserve. Underwater distributary channel sand is typical channel sand body,mainly distributing in non major reservoirs from Lamadian Oilfield to Xingshugang Oilfield of Daqing Oilfield. Underwater distributary channel in Lasaxing Oilfield was taken to be main research object,using stratification testing of sealed coring inspection well&oil-water well,well log interpretation of water flooded layer and production data,remaining oil formation mechanism of underwater distributary channel in Lasaxing Oilfield was studied by using sealed coring inspection well data analysis method,reservoir engineering method,reservoir numerical simulation method,physical simulation and comprehensive analytic approach. The remaining oil distribution pattern was presented.
