【摘要】：方正油田方4區(qū)塊位于黑龍江省通河縣,方4區(qū)塊烏一段油藏的形成主要受構造條件控制,具有一定的構造幅度,同時早期或繼承性發(fā)育的斷裂對油氣具有一定的側(cè)向封堵性,油藏上油下水,具有統(tǒng)一的油水界面,是典型的受構造控制的斷塊油藏。地質(zhì)研究發(fā)現(xiàn),方正斷陷整體表現(xiàn)為兩凹一凸兩斜坡的構造格局,可以劃分為南部斜坡帶、東部凹陷帶、西部凹陷帶、北部凸起帶和西部斜坡帶五個二級構造單元。巖性上以含礫砂巖、細砂巖、暗色泥巖和煤層為主。對層內(nèi)韻律性、巖心資料分析、孔隙度、滲透率剖面分布、砂體幾何形態(tài)和連續(xù)性、孔隙度、滲透率平面分布特征等參數(shù)研究發(fā)現(xiàn),儲層具有縱向和橫向的非均質(zhì)性。從地面原油性質(zhì)看,該區(qū)原油油質(zhì)較輕,具有低密度、低粘度、低凝固點、含蠟量中等的特點,屬于揮發(fā)性油藏。本文根據(jù)方4區(qū)塊特低滲透,導壓能力低等特點,確定采用人工補充地層能量的方式開采。結合長春油田等相似油田的生產(chǎn)經(jīng)驗,分別對注氣開發(fā)和注水開發(fā)方式進行了可行性評價,確定本區(qū)塊的開發(fā)方式。并針對開發(fā)方案、井網(wǎng)設計、工作制度選取、井位部署等進行了優(yōu)選,同時對開發(fā)指標進行預測及對開發(fā)方案進行了經(jīng)濟評價。
[Abstract]:Fang4 block in Fangzheng Oilfield is located in Tonghe County, Heilongjiang Province. The formation of Wuyi member reservoir in Fang4 Block is mainly controlled by structural conditions and has a certain tectonic range. At the same time, the early or inherited faults have certain lateral plugging to oil and gas. It is a typical fault block reservoir controlled by structure with uniform oil-water interface. Geological study shows that the Fangzheng fault depression is characterized by two concave and two convex slopes, which can be divided into five secondary structural units: the southern slope zone, the eastern depression zone, the western sag zone, the northern uplift zone and the western slope belt. Lithology to gravel sandstone, fine sandstone, dark mudstone and coal seams. It is found that the reservoir has vertical and horizontal heterogeneity by studying the rhythmicity, core data analysis, porosity, permeability profile distribution, sand body geometry and continuity, porosity, permeability plane distribution characteristics and so on. The crude oil in this area is characterized by low density, low viscosity, low freezing point and medium wax content, so it is a volatile reservoir. According to the characteristics of very low permeability and low pressure conductivity in Fang4 Block, the method of artificial supplementary formation energy is determined in this paper. Based on the production experience of similar oilfields such as Changchun Oilfield, the feasibility evaluation of gas injection development and water injection development is carried out, and the development mode of this block is determined. The development plan, well pattern design, work system selection, well location arrangement and so on are selected, and the development index is forecasted and the economic evaluation of the development plan is made at the same time.
