高西油田精细油藏描述及剩余油分布规律研究
|
摘要
大庆长垣西部外围地区分布着一批地质条件复杂的“低产、低渗、低丰度”的小块油田。这些油田具有多层系含油、多种圈闭类型、油气富集程度不均，油气水纵向、横向关系复杂的特点。对于这类油藏，采用常规的钻井开发技术很难在短期内认识清楚，并且经济效益也很差；必须将地质、地震、测井、油藏工程等多专业、多学科有机地结合起来，发挥多学科协同合作的优势，采用先进的预测技术及油气储层识别技术，开展精细地质研究工作，才能不断深入对油藏的认识，提高钻井开发的整体效益。近年来，在大庆西部外围地区的高西、新店、布木格、新站、新肇、龙南等低渗透油田钻井开发过程中，综合应用了地震预测技术、测井评价技术、油藏工程技术、地质综合分析技术等技术手段，并且将他们有机结合起来，取长补短，优势互补，提高了油藏描述的预测水平，有效地指导了钻井开发工作，取得了较好的效果。
本文针对高西油田开发中暴露出的主要矛盾，开展以细分单元、微相划分、储层非均质描述为主要内容的精细地质研究工作，为地质条件相近的布木格、龙南等油田积累经验和储备技术。结合高西地区的地质特点和油田开发的实际需要，把精细地质研究工作的重点放在以下几方面：
1、针对该地区动静不符比较突出的实际情况，开展了纵向划分沉积单元、横向细分沉积微相的精细沉积相研究，重新认识储层的发育特征和空间分布规律，为注采关系调整提供更加可靠的地质资料。
2、采用动静结合的办法，分析各砂体的储量动用状况，搞清剩余油分布规律，充分挖掘储量潜力。
3、应用精细地质研究成果，编制综合治理方案，改善油田开发效果，提高油田开发效益。
There are a series of low production, low penetrability, and low saturation oil field in the west of Changyuan of Daqing. These oil fields contain many oil quoit and there are on enough oil and gas and there are complicated characteristic. It is very difficult to realize the technology of artesian well and its economic benefit is very bad. We should connect the geologic earthquake, measure well, reservoir with other subject and reservoirs technology of oil and gas. We should develop fine geological study and increase the whole benefit of artesian well exploitation. In recent years, we apply earthquake forecast technology, measurable well appraise technology and geology analyze technology and connect them with other technology and increase the forecast level of reservoir describe and direct the exploit work of artesian well and acquire fine effect.
In this text, aim at main questions that exposed in the Gaoxi oil-field development, the fineness Reservoir Description researching work was done. For improving the oil-field development result, accumulating experience and storing technique for oil fields, such Bumuge oilfield, Longnan oil field etc. whose geologic condition are similar. Connect with the geology characteristics and demand in oil-field develop, the points of the work to the fineness reservoir description are as follows
1. Aimed at the region's action does not agree with the actual circumstance, fineness sedimentation microfacies was studied, by it the growth characteristic and distributing regulation were well known, offering more dependable geology data for relationship between injection and production.
2. The way of action combination was adopted to analyze each sand body condition and know remaining oil distribution regulation, deeply develop the potential of oil field.
3. Established synthesizes managing project, and improved the oil-field development result by applying the fineness reservoir description result, result to increasing oil-field development performance..
