摘要
根据中原油田深层低渗复杂断块油藏开发状况,建立该类油藏最小含油面积、开发投资、收益、油藏开发经济可行性、油藏递减规律、经济规模储量等计算模型。开发经济技术界限研究表明:边际油藏最小含油面积为0.02 km2;油井经济界限产量受油藏埋藏深度、原油价格、吨油操作成本的影响,其中油藏埋藏深度、原油价格是影响油井经济产能的敏感因素;最小储量规模受油藏埋藏深度、采收率、原油销售价格、吨油操作成本等影响,其中油藏埋藏深度、原油销售价格是影响经济规模储量的敏感因素。由于原油价格不断上涨,原来评价为低效或无效的小规模储量可能已变为可开采的经济储量。对卫360块沙三段中亚段6-7油藏总体评价结果表明,该油藏处于经济开发的边缘。
This article builds up the computational models of the minimum oil-bearing area, development investment, development profit, economic feasibility, decline rules and economic reserve scale of deep low-permeabilhy reservoirs. Study shows that the minimum oil-bearing area of the marginal reservoir is 0.02 km^2 ; the economic threshold production is affected by reservoir burial depth, price of the crude oil, and operation cost of per ton of oil, of which burial depth and crude oil price are the sensitive factors affecting the economic production capacity; minimum reserve scale is affected by burial depth, recovery and consumption price of the crude oil and the operation cost of per ton of oil, of which burial depth and the consumption price of the crude oil are the sensitive factors affecting the economic reserve scale. Because of the increasing crude oil price, the original low efficiency or invalid reserves could be reestimated as the economic ones. The Esx^6-7 reservoir of the block Wel 360 is on the edge of the economic development.
