摘要/Abstract

摘要： 塔中4油田石炭系巴楚组含砾砂岩段层状边水油藏埋深约3 700 m，边水能量弱，地层压力保持程度低；其下伏的东河砂岩段油藏发育大型水体，压力保持水平较高，2套层系间的层间压差为15~25 MPa. 通过分析井区因层间压差导致层间倒灌形成自流注水的矿场实例，结合塔中4油田的油藏地质和开发特征，建立了数值模型，并模拟了层间倒灌、分别采用直井和水平井作为自流注水井等不同井型和井网条件下自流注水技术的开发指标。研究表明，在巴楚组含砾砂岩段层状边水油藏进行自流注水是可行的，并优选出下步矿场试验井组。

Abstract: The pebbly sandstone section of the Carboniferous Bachu formation in Tachong 4 oilfield in Tarim basin is a layered edge water reservoir of burial depth of about 3 700 m and characterized by weak natural energy and low degree of formation pressure. The underlying Donghe sandstone section of it is characteristic of in?situ large water body and higher degree of formation pressure. The interlayer pressure difference between the 2 sets of series of strata or reservoirs ranges from 15 to 25 MPa. This paper analyzes the field case of in?situ dumpflooding from interlayer cross flow caused by the interlayer pressure difference, and builds a numerical model for the reservoir geology and development features of Tazhong 4 oilfield, by which the dumpflood development indices by using different types of producers (vertical well and horizontal well) as dumpwater injectors and different well patterns as well as interlayer cross flow are simulated. The results show thatapplication of dumpflood technology to such a layered edge water reservoir is feasible in this oilfield and further pilot test area of well group is selected as well
